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
New modular design of GIXflow
A flowchart draft representing the planned modular design of GIXflow. Read more here.
Realtime stats in GIXflow
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
A new version of GIXflow
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
An improved version of GIXLG
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
A new version of GIXLG
The code of GIXLG has been fully rewritten and is capable to process JSON format now.

A first public release of GIXLG is available
On 30th August a first public version was released and is available in Google code repository.
Netflow packets decoder
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.
Migration from Quagga to ExaBGP, new looking glass
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 MySQL plugin to ExaBGP during testing process
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
