Barefoot‘s Tofino is a world’s fastest and fully user-programmable switch series able to handle up to 6.5Tb/s (65 X 100GE or 260 X 25GE). In their whitepaper Barefoot describes PISA (Protocol Independent Switch Architecture), a new model for processing packets at
A flowchart draft representing the planned modular design of GIXflow. Read more here.
Real-time stats and a few more features have been added to GIXflow. Added real-time stats include: – total volume of TCP/UDP/ICMP/IPv6/OTHER traffic – packet rate for TCP/UDP/ICMP/IPv6/OTHER traffic – received and processed packets – received and processed flows – prefix cache
Several features have been implemented to GIXflow: – Processing NetFlow v9/v10 templates. – Processing NetFlow v9/v10 data based on learnt earlier templates. – Adding support for IPv6 flows. – Adding stats for received and processed NetFlow packets, separate for IPv4
Several improvements have been implemented to GIXLG: – Multithreading. A few threads can now process updates received from ExaBGP. – A prefix cache to limit number of SQL queries. – An option to turn off all SQL operations. – Better
The code of GIXLG has been fully rewritten and is capable to process JSON format now.
Monitor your network for DDoS ExaDDOS is an application able to gather different data sources to present a real time unified view of your network. It can gather : SNMP information at your edge IPFIX export from your routers And
IXLeeds 3 will take place at aql’s Salem Chapel, Leeds on 20th June 2013 and is going to be biggest event so far.
The experimental version of AS-Stats (AS-Stats + ExaBGP + MySQL + Memcached) with Netflow v9, v10 (IPFIX) and IP2ASN mapping support is available as a GitHub project.
IXLeeds 2 took place at the Carriageworks, Leeds on 12th September 2012. IXLeeds 2 was second event and opened to members and non-members. The content of the presentation is available here.
On 30th August a first public version was released and is available in Google code repository.
Thanks to TVK for joining GIX with the IPv6 session. Network maps are available under following links: PNG image and SVG image.
NetFlow packets decoder written in Python works fine. It can be used combined with the route collector code in order to assess amount of traffic passing through a particular path.
ExaBGP works well, so all sessions were switched from Quagga to ExaBGP. New GIX looking glass is also ready. I am still working on processing Quagga dump files with updates (not only full dumps) from RIPE NCC and Route Views
A plugin to ExaBGP to inject prefixes directly to a MySQL database is almost ready (during testing process). I am going to prepare a replacement for KLG/MRLG looking glasses which will use directly MySQL database instead of Quagga cli and
