Network Processor: May 2005 Archives
TIPPINST - The Irish times are reporting in the technology section of their newspaper about the 15 million euro funding round led by Apax Partners, one of the world's biggest private equity firms. ACT Venture Capital and Cisco Systems are also investors in Corvil Networks.
Corvil is a recent startup who develop a number of products that analyse packet switched ip based networks so as to provide better levels of QoS. From talking to some of the people in Corvil last year I understand that they are in the process of developing a family of appliances for high speed links with additional functionality such as deep/stateful classification, content classification, shaping, policing etc. At the time they were considering using the Intel IXP2400/IXP2800 with classification and encryption processor support.
Some of the algorithms encompassed in the products were developed by the Dublin Institute for Advanced Studies (DIAS) who had filed several patents in the area of QoS in particular how TCP is handled.
Forrester research highlighted Corvil last december as as leader in the area of QoS.

TIPPINST - My site receives numerous queries from China regarding the intel network processor and related research. It came as no surprise when google alert informed me of the Network Processor Group at Tsinghua Univeristy in the Peoples Republic of China. They describe on their site an Intel Council funded project titled "AntiWorm NPU-based Parallel Bloom filters in Giga-Ethernet LAN".
The main idea is to find and locate the worm by detecting the signatures of worms in every packet en route. NPU-Based implementation can scan every packet with high performance and can live update the worm’s signature flexibly to keep pace with fast evolution of worms.

TIPPINST - I recently put up a wanted notice for an ixp1200 die photo, I came across a site today that contained the info I required when I was looking for something else (google is not yet perfect).The gigascale research centre have a document title Modeling peripherals http://www.gigascale.org/mescal/forum/174/modeling-peripherals.pdf. This pdf contains IBM, Intel and Motorola die photos as well as some details on area and power consumptions.

TIPPINST - As part of our research into the ixp1200 network processor we require a die photo. Any suggestions or photos to lnoonan_blog at yahoo.ie.
TIPPINST - A number of companies are starting to ship Carrier Grade versions of their realtime operating systems, the latest to do is FSMlabs who have registered their version with the ODSL. AS the name implies Carrier Grade Linux specifications adhere to the characteristics required by carrier-grade applications. Carrier Grade Linux complies to recognized standards such as the Linux Standard Base. The effort is aligned with existing forums and communities such as the Service Availability Forum.
Eventhough companies are adhering to a common standard they are going to great lengths to differeniate their products from a performance point of view
Until now carrier grade linux has focussed on the control plane and left companies such as Windriver to handle the data plane.
Control plane traffic is typically queued in multiple priority queues since it is not processed "on the fly" like data plane traffic. Examples of control plane include
•Protection against DoS attacks at infrastructure routers and switches
•QoS control for packets that are destined to the control plane of routers or switches
Hemant Trivedi at Commsdesign believes that integration of the control and data plane is essential if 10Gbs plus speeds are to be achieved. FSMlabs agree with Hermant and have this objective firmly in mind.
Network processors in the future will also have to achieve both control and data plane handling, this requires high speed low jitter solutions.
