The Cisco 7600 OSR consists of a 256 Gbps switching fabric and a 30 million packets per second (mpps) forwarding engine. Its breadth of IP services comes from Cisco IOS, which provides features such as security, enhanced QoS, and destination sensitive services. In addition, the Cisco 7600 OSR allows the migration of existing port adapters from Cisco 7500 series routers, via the Cisco FlexWAN module, giving service providers one the industry’s widest array of interface options in any single platform. This provides service providers great flexibility in deploying the Cisco 7600 OSR for a variety of applications, protects their investment in existing systems, and gives them a practical migration path to the New World Optical Internet.

A Revolutionary Platform For Evolving Networks

The Cisco 7600 OSR helps service providers break through service and bandwidth barriers today, while designing networks to scale for future growth. The Cisco 7600 OSR achieves this through “adaptive network processing,” or the ability to evolve the platform for new IP services without hardware upgrades. Unlike fixed, ASIC-based platforms, which are hardware encoded, the Cisco 7600 OSR relies on the highly flexible Parallel eXpress Forwarding (PXF) technology for scalable performance of services. PXF is a patented, Cisco-developed network processor capable of line-rate IP services delivery that can support new IP services through periodic software upgrades. Each OSM has two PXF processors capable of 12 mpps of IP services delivery per interface card.

“IP+Optical combines the dynamism of the Internet world with the foundation of the transport world, creating an infrastructure that can deliver the services that service providers need,” said Lele Nardin, vice president of the Internet Systems Business Unit at Cisco. “Cisco will continue to add innovative solutions on top of this solid foundation to make service providers better equipped to meet the constantly escalating and changing customer demands for new networking services.”

Pricing and Availability

The base Cisco 7600 OSR system is list priced at $73,000 and the entry level system, with interfaces, start at $100,000. The interfaces modules are priced between $27,000 to $180,000. The Cisco 7600 OSR is available now worldwide.

I agree that these gentlemen are top notch researchers, witnessed by the fact that the authors do not mention nor claim to be “complex event processing” anywhere in their paper!  This paper is not about CEP, nor does it claim to be about CEP, it is about stream processing and unifying SQL standards.

ABSTRACT: This paper describes a unification of two different SQL extensions for streams and its associated semantics. We use the data models from Oracle and StreamBase as our examples. Oracle uses a time-based execution model while StreamBase uses a tuple-based execution model. Time-based execution provides a way to model simultaneity while tuple-based execution provides a way to react to primitive events as soon as they are seen by the system.

Asmentioned on numerous occasions, stream processing is a very important area in CEP/EP.   It is important not to confuse the higher situational knowledge from object-object correlation and state management with the single-object event refinement that occurs in stream processsing.    Event stream processing is fundamentally different than complex event processing. 

Event stream processing performs operations on streaming event objects.   In almost all advanced CEP/EP applications is is necessary to perform robust track and trace operations on streaming event objects, like tracking the position of an airplane.    Tracking the position of an aircraft can be modelled very nicely with event stream processing.  Tracking individual event objects is a precuror to multiclass object situation refinement.

When we manage the state of all the aircraft in the skies over New York, you need more than a stream processing construct.  You need to manage the state of all the aircraft.  Paul Vincent of TIBCO Software being to address this important point in The Value of State…  

Again, we will be better equiped to solve complex distributed event processing problems if we do not confuse the notion of event stream processing and complex event processing.   These technologies are indeed complimentary, both very important, but they are not the same.

I applaud Oracle and StreamBase’s work toward a unified standard for SQL extensions for streams.

I arrived in Austin Sunday night to get ready for a factory tour on Monday, a kickoff dinner and then two days of briefings from Dell executives, including Michael Dell himself! Dell’s ISG business is growing at a very fast pace and continues to build momentum and focus within the broader organization.

We had a nice overview of the product roadmap, including some of the exciting enhancements Dell is making to their storage products such as the MD3000 and the new EqualLogic PS5000 series iSCSI solutions.

I really enjoyed the Council meeting and it reminds me all over again; what I admire about Dell is the way they and Michael Dell himself stay close to the customer. The entire purpose of this event is to “get it right” and determine meaningful ways to embrace change (including change in the manufacturing process) in order to make their customers more successful. Ah shucks, you may say that all companies behave this way… well I must tell you that is not true and at times, I find it difficult as we continue to grow to stay as close as I would like to all of our customers varying needs and directions.

This concept of gathering, internalizing and embracing customer feedback is a simple principle of Business Success stories. Always trying to improve the pace of change and build meaningful sticky relationships with customers. Dell’s very successful Ideastorm site where customers post product feedback and are active participants in the Dell community is a great example of how to do this right. No other hardware vendor that we have worked with or attempted to work with has ever gone to the extent of embracing change that Dell has during our 5-year relationship.

From the custom factory integration services to the attention to detail in the order and manufacturing, and logistics processes, Dell helps us execute for our customers and I must admit that we could not have built the business as quickly or efficiently without Dell!

So thank you Michael Dell for building a business that embraces change and is focused on helping your ISG customers succeed.

The following excellent discussion is reposted from Streaming SQL approaches insist in ignoring causality by PatternStorm.

The recent paper “Towards a Streaming SQL Standard” by Oracle and Streambase unifies and generalizes two different execution models of Streaming SQL: Oracle’s and StreamBase’s.

While it’s true that the generalization succeeds in overcoming the unability of both execution models of producing correct results for astonishing simple queries (showing evidence of the actual limitations of these two Streaming SQL languages) it is also true that the generalization is closer to being overly complex than natural and intuitive.

The root cause behind the actual limitations of these two Streaming SQL languages is that their execution models “hardcode” the way events can be related to each other: in the Oracle case events are partially ordered by timestamp, in the StreamBase case events are totally ordered by time of arrival. These design decisions (natural in a stream oriented lamguage) have strong implications on what queries can be answered correctly, particularly when these queries involve joins of derived streams.

The generalization, of course, mainly consists in providing a new operator that allows the user to establish custom ordering relationships among the events (the SPREAD operator), which is good news but takes us to the fundamental issue: event processing cannot be reduced to stream processing, that is, to the processing of events that are totally or partially ordered by a pre-defined relationship (as Oracle and StreamBase actual implementations do), on the contrary, no particular ordering can be assumed because the user needs to be able to order the events in different ways in order to solve different problems. This is what event processing is about and the paper provides evidence that Streaming SQL approaches have found the need to move towards that direction and are having trouble in their way.

For instance, one of the queries used in the paper as an example of a query that StreamBase cannot solve (but Oracle can) is the following: correlate the stream that contains the total number of cars on the road for each time interval with the stream that contains the total average speed of the cars on the road for each time interval in order to detect the situation where the avergae speed is below 45 and the total number of cars is two or more. This query can be very easily and more robustly solved if you order the events by causality rather than by time, that is, if you have each position report update the average speed stream and the total number of cars stream and then you causally relate each position report to the new average speed event and the new total number of cars event that it generates; then the query is just a matter of detecting all report speeds that are causally related both to an average speed event below 45 and a total number of cars event of two or more (notice that this approach is more robust than Oracle’s time-based one because it works without requiring derived streams to be synchronized with the report speed stream)

Conclusions:

• Event Processing is a generalization of Stream Processing (as the paper shows)
• Event Processing requires providing the ability to the user of creating custom relationships among events and then define patterns/queries using those custom relationships.
• Causality is more often than not a more robust and easier criteria to order events than time or order of arrival.
• Event Processing Languages should support causality.

First, the most obvious conclusion: people still don't care much about log security; I am saying that since this was BY FAR the least popular of my polls. Only 24 people responded, so everything below is pretty unscientific :-)  A good way to explain it: look at the recent media? Do these people care about their key business data and their customer data security? Nope. So, how on Earth do you make them care about securing their log data?

Second,  it is entirely unsurprising that 83% of respondents want "Authenticated access to log server." In fact, I'd opine that 100% of people want authenticated access to any of their servers :-) But, this was my "red herring" to set the baselines for the rest of the questions... 

However, this is where the buck stops: other security measures are notably less popular.

Third, "Logging all access to logs" is my favorite and I am happy to see it reported as popular. But do you really do it?  Do you log access to log server OR access to actual logs? Think about it... I think a lot of people who do the latter still answered "yes" to this one.

Fourth,  "Reliable / acknowledged network transfer of log data" and "Encryption of log data in transit " are two true "no-brainer" security features; they took the next spot at 45% and 50% of those who answered. They are simple, they are easy, they make  sense - and, obviously, they don't make logs entirely secure so you need to do more. Why only 50%? Where is THE OTHER 50%?!

Fifth, "all things crypto" are below 40%. "Cryptographic hashing of stored logs", "Cryptographic signing of stored log data" and "Encryption of stored log data" all hover at around 30%. I attribute them to general disregard of log security AND reliance on "system security" (separate server, etc) over "data security" measures for log protection.

Finally, I am embarrassed to say that I missed  the obvious security measure "Separate server for logging, not accessible from the Internet;" one of my readers added this using "Other security measures" choice. Indeed, this is a good point - and a good idea to do it. Another option mention there was "Destroy old logs." Amen to that too!

So that's what he asked for, and that's what he got. And now it's time to create some cryptographic applications for the rings. Cory and I are holding an open contest for the cleverest application.

I don't think we can invent any encryption algorithms that will survive computer analysis -- there's just not enough entropy in the system -- but we can come up with some clever pencil-and-paper ciphers that will serve them well if they're ever stuck back in time. And there are certainly other cryptographic uses for the rings.

Here's a way to use the rings as a password mnemonic: First, choose a two-letter key. Align the three wheels according to the key. For example, if the key is "EB" for eBay, align the three wheels AEB. Take the common password "PASSWORD" and encrypt it. For each letter, find it on the top wheel. Count one letter to the left if there is a dot over the letter, and one letter to the right if there is a dot under it. Take that new letter and look at the letter below it (in the middle wheel). Count two letters to the left if there is a dot over it, and two letters to the right if there is a dot under it. Take that new letter (in the middle wheel), and look at the letter below it (in the lower wheel). Count three letters to the left if there is a dot over it, and three letters to the right if there is a dot under it. That's your encrypted letter. Do that with every letter to get your password.

"PASSWORD" and the key "EB" becomes "NXPPVVOF."

It's not very good; can anyone see why? (Ignore for now whether or not publishing this on a blog makes it no longer secure.)

How can I do that better? What else can we do with the rings? Can we incorporate other elements -- a deck of playing cards as in Solitaire, different-sized coins to make the system more secure?

Post your contest entries as comments to Cory's blog post -- you can post them here, but they're not going to count as contest submissions -- or send them to cryptocontest@craphound.com. Deadline is October 1st.

Good luck, and have fun with this.

It's not just terrorism; it's any rare risk in the news. The big fear in Canada right now, following a particularly gruesome incident, is random decapitations on intercity buses. In the US, fears of school shootings are much greater than the actual risks. In the UK, it's child predators. And people all over the world mistakenly fear flying more than driving. But the very definition of news is something that hardly ever happens. If an incident is in the news, we shouldn't worry about it. It's when something is so common that its no longer news - car crashes, domestic violence - that we should worry. But that's not the way people think.

Psychologically, this makes sense. We are a species of storytellers. We have good imaginations and we respond more emotionally to stories than to data. We also judge the probability of something by how easy it is to imagine, so stories that are in the news feel more probable - and ominous - than stories that are not. As a result, we overreact to the rare risks we hear stories about, and fear specific plots more than general threats.

The problem with building security around specific targets and tactics is that its only effective if we happen to guess the plot correctly. If we spend billions defending the Underground and terrorists bomb a school instead, we've wasted our money. If we focus on the World Cup and terrorists attack Wimbledon, we've wasted our money.

It's this fetish-like focus on tactics that results in the security follies at airports. We ban guns and knives, and terrorists use box-cutters. We take away box-cutters and corkscrews, so they put explosives in their shoes. We screen shoes, so they use liquids. We take away liquids, and they're going to do something else. Or they'll ignore airplanes entirely and attack a school, church, theatre, stadium, shopping mall, airport terminal outside the security area, or any of the other places where people pack together tightly.

These are stupid games, so let's stop playing. Some high-profile targets deserve special attention and some tactics are worse than others. Airplanes are particularly important targets because they are national symbols and because a small bomb can kill everyone aboard. Seats of government are also symbolic, and therefore attractive, targets. But targets and tactics are interchangeable.

The following three things are true about terrorism. One, the number of potential terrorist targets is infinite. Two, the odds of the terrorists going after any one target is zero. And three, the cost to the terrorist of switching targets is zero.

We need to defend against the broad threat of terrorism, not against specific movie plots. Security is most effective when it doesn't require us to guess. We need to focus resources on intelligence and investigation: identifying terrorists, cutting off their funding and stopping them regardless of what their plans are. We need to focus resources on emergency response: lessening the impact of a terrorist attack, regardless of what it is. And we need to face the geopolitical consequences of our foreign policy.

In 2006, UK police arrested the liquid bombers not through diligent airport security, but through intelligence and investigation. It didn't matter what the bombers' target was. It didn't matter what their tactic was. They would have been arrested regardless. That's smart security. Now we confiscate liquids at airports, just in case another group happens to attack the exact same target in exactly the same way. That's just illogical.

This essay originally appeared in The Guardian. Nothing I haven't already said elsewhere.

Cablevision will ultimately spend about $300m in building a Wi-Fi network exclusively for its customers; 2.4m of these customers qualify to use the service at no cost. There's no pay as you go option, no monthly subscription; you're either a subscriber of theirs, or not. It's a fascinating strategy, because they're leveraging all these dollars as a tool to crack its competitors in the market. With increasing competition from telephone companies that are offering television service, cable companies need to compete on voice, data, and video, as well as well as on mobile offerings. When the network is built, Cablevision can conceivably offer Wi-Fi telephony service, too.

I'm dying to know what the reduced churn rate and increase in subscriptions will be in six months. Given that hotspot access costs $10 to $30 per month depending on the network, Cablevision is delivering something of value. It's great honey for new subscribers and glue to keep current subscribers.

The company is claiming that with this latest activation, they have the largest Wi-Fi network for consumers in the U.S. They're likely correct. The only other public access network of scale that's being used by large numbers is in Minneapolis, and based on what I know about both networks, Cablevision probably deserves bragging rights. The network in Taipei, Taiwan, is likely still larger, but I haven't heard any usage number in nearly two years; at that point, subscription rates were 10 percent of what had been projected.

• ValidationSummary controls look at the ErrorMessage field to figure out what to display, so always use ErrorMessage in a verbose enough way that it will be helpful from a ValidationSummary control.
• If you need a shorter message to display inline (i.e., where the validation control is on the form, as opposed to the ValidationSummary) use the body of the control to define it.

In the past, I've used RequiredFieldValidator controls on my web forms to remind users that certain fields are required. I would set the ErrorMessage to something vanilla like, "This field is required", or even something simpler like "*" (an asterisk) if I didn't have much room on the form to display more prose for an error.

A friend was recently testing a new feature that I'd built for our sales team and she had a hard time seeing the little red asterisks that were showing up next to required fields. It felt to her as though she was pushing the submit button on the form but nothing was happening. It was clear that a ValidationSummary control would be helpful, especially if placed close to the submit button for the form.

I've been a bit lazy in the past about using ValidationSummary controls, partially because most of my forms are simple enough that they feel a bit redundant. But on a more complicated form, they can be very helpful to guide users back to the places on the form where there's problems.

So I threw one of those puppies on the form and immediately saw that there was a problem - my error message was set to "*", which meant that my validation summary was pretty useless - it just displayed a bunch of red asterisks! And in places where I'd used the prose, "This field is required", well that was pretty useless as an error message in the summary.

After a bit of research and experimentation, I discovered that the ValidationSummary control looks at the ErrorMessage property on each validation control in order to figure out what to display in the summary. So it's important to use ErrorMessage with a summary in mind! Don't use text like "*" or "This field is required". Be more specific so the user can find her way up to the problem field, as in, "PostalCode is required".

But if you make ErrorMessage verbose so that it's helpful in a summary, it may make your form really ugly when displayed inline next to the control being validated. The trick is to use the body of the validation control element to specify the inline error message. Then you end up with two messages: a verbose one that's used in your summary, and a more localized, brief message that shows up right next to the control being validated. Note the asterisk that's in the body of the RequiredFieldValidator below:

<asp:RequiredFieldValidator
      ErrorMessage="Zip/postal code is required"
      ControlToValidate='txtPostalCode'
      ValidationGroup='BasicInfo'
      Display="Dynamic"
      runat='server'>*</asp:RequiredFieldValidator>

I've learned a lesson from all of this. In the future when I use validation controls I'll always provide a summary-friendly message in the ErrorMessage field, and if I need something different (typically shorter) to display inline, I'll put it in the body of the validation control element.

Hope this helps!
