So, lets dig into LISP Routing a little more. If you have not done so, I would recommend you read my first post, since I am not going to review the concepts here. In this post, I am going to break things down into three steps: 1) how packets are forwarded (i.e. the data plane operation), 2) how mapping information is propagated (i.e. control plane operation), and 3) how we internetwork with non-LISP locations.
For starters, lets head into the weeds and take a look at the LISP header format. In the last post, I mentioned there is some flexibility in how handles IP addressing. The two examples below show a couple of scenarios: pure IPv4 and a IPv4/IPv6 hybrid:

Guest Blogger: Jamie MacQuarrie (@JMacQuarrie) has been working on Cisco’s cloud solutions, strategy and alliances since joining Cisco with the acquisition of newScale in April 2011. At newScale, he held product management positions focusing on data center automation and the evolution of traditional data centers to cloud operating models. Prior to joining newScale, he held product management positions at BMC Software and IT management positions at Washington Mutual bank. He started his career at Marimba, which was acquired by BMC Software in 2004.
We’re now into November, and though Halloween has come and gone, Cisco still has one last treat for everyone: Cisco Intelligent Automation for Cloud 3.1.
There have been a number of blog posts on the veritable cornucopia of features in IAC 3.1, so instead I’ll offer up this fun look at cloud maturity and extend the Halloween season just a little bit longer.
So tonight at 3am, long after your kids have gone to bed and you’re wired from eating all of their candy, instead of surfing the web trying to find the bottom of the internet, let me suggest a few more productive activities:
- Take a look at the Intelligent Automation blog posts
- Figure out what kind of Jack o’ Lantern your cloud strategy resembles
- Take your actual Jack o’ Lantern off your porch before it start attracting flies
And yes, that is a photo of a carved watermelon….It’s more popular than you might think.

On October 5th I posted part 1 of the Algo Boost series with a fantastic discussion around the latency innovations on the Nexus 3548. Today, we announced that these units are now shipping to customers and the much anticipated wait is over to get this game changing technology! This is perfect timing as I introduce part 2 of the series with Errol Roberts, Distinguished System Engineer for the top Data Center accounts, to bring a customer perspective to the ultra-low latency Nexus 3548 in a High Performance Trading fabric.
[GD] I know that you spend a lot of your time talking with customers. What are our Financial Services customers telling you about their environments and requirements?
[ER] When meeting with these customers, I like to ask a single question – “What value can an infrastructure company provide to high-performance trading workloads”. Key points relating to the switching are captured by the following:
- First, customers ask for a network solution and architecture that provides them with the fastest end-to-end functionality. Providing the “Lowest latency possible” is one vector, another vector being a rich “feature-set” answering the different architecture and network requirements end-to-end. Naturally there is a need for speed while at the same time providing the features within the same device. For example in collocated High Frequency Trading environments; the lowest latency being key; it’s not the only factor; support for the routing protocol such as BGP, multicast with PIM Sparse mode, ultra low latency SPAN at linerate with multiple ports; this is achieved with the technology called Warp SPAN.
- Next, “Handle microbursts”. Volatility is correlated. When you are running cross-asset class, cross-liquidity venue strategies, there is often short-lived congestion that increases latency. These volatile periods are often the most opportunity rich.
- Also, “Unique features”. They want features like Network Address Translation to meet their business needs. You don’t want these features to add latency. In fact you don’t want to have any of the L4 or services applied on the network to add latency.
- Next, “Flexibility and Programmability”. They want to control their traffic flow, mirror relevant traffic, have fine-grained flexibility and also have reactivity on events. Python scripting language is a good example of automation. With Python script, you can have the switch react on different environmental changes such as a sanity check when the device comes online as well as for example triggering emails when the burst happening at the buffer level exceed for example 10 nanoseconds.
- In addition, facilitate “Precision Time”. You cannot control what you cannot measure. Without precision time, you invest in an infrastructure and just hope you get optimal performance. With precision time protocol you can keep all of your servers and network elements highly synchronized at the nanosecond level. You can even measure the accuracy of the tool through a 1 pulse per second output port. Also, the Nexus 3548 can timestamp traffic with IEEE 1588, which allows analyzers to replay events.

If you haven’t already found your way into Cisco’s new online UCS Build and Price portal, there are some very interesting “Smart Plays” awaiting you. You can check our new UCS promotions page regularly to find the latest UCS Server Smart Plays such as the UCS B200 M3 Value Smart Play, currently offered (limited time) at only $7600. This includes two Intel® Xeon® processor E5-2650’s with 16 cores, 64 GB of memory, one VIC 1240 and one VIC 1280 virtual interface card offering a combined 80Gb of IO throughput in a half-width blade server. This blade server is a real powerhouse in a compact package and now it’s offered at an exceptional price through Cisco Build and Price.
See the new line-up of Cisco UCS blade servers and rack servers with Intel Xeon processors that just claimed another eight new world-record industry benchmarks.
Cisco UCS Performance Brief
Cisco UCS B200 M3 Blade Server
These same servers are now available at competitive prices as Smart Plays on Cisco’s new Build and Price portal. Download specifications, performance reports and compare blade server prices on these popular servers while they last.
In his most recent Blog on October 8th, Girish Kulkarni highlights several new World Record Benchmarks for Oracle E-Business Suite on the UCS B200 M3 Blade Server. You can see all UCS Rack Server and Blade Server World-Record Benchmarks on our Performance Benchmarks page on Cisco.com.

As a quick reminder , to participate to this 6 weeks challenge and have a chance to win every week a new iPAD, you want to visit our Facebook page. The questions are submitted on Sunday midnight PST, and answers have to be provided by Friday noon PST. Participation is easy and fun and allow you to collect points to compete for the highest IQ score. This best Unified Data Center “brain” will be the winner of the Grand Prize (valued US $2000). Every week-end , you can answer bonus questions, which give you additional points to catch up for the Grand Prize
So it’s Friday again, and we just finished the 5th week of this contest!
And it’s now time for our bonus questions ! This coming week –end bonus question are covering Intelligent Automation , LISP, Nexus 7000 , big data , and Cisco Validated Design (CVD) for Cloud . If you check regularly our blogs, you are in a good place – Following also @drombaut and @ciscodc is a good idea to get clues .
Each correct answer will give you 20 points – So you don’t want to miss the opportunity to catch up for the Grand Prize.
If your Unified Data Center IQ is higher than 100 , you still can be the winner , as this week-end can bring you 100 points , the next week another 50 points , and the following week-end another 100 points.
BTW, next week questions , starting on Sunday midnight , will be about UCS Central and UCSM (did you check the announcement?). Another great opportunity to win an iPad!
