OpenFlow in Moscow
To the attention of all progressive system administrators well and just lovers to look into the future!
Tomorrow at 16:00 a seminar on the problems and future of computer networks will be held at Moscow State University, the seminar is supported by the Skolkovo Center for Applied Research of Computer Networks - and this is a unique opportunity to communicate directly with the developers of the OpenFlow protocol and learn how computer networks will be built in 5-10 years.

In short, OpenFlow is an attempt to develop network protocols from scratch, but with 40 years of experience in the existence of networks and immediately under current conditions with an avalanche of traffic. In the OpenFlow switch, only the data transfer layer is implemented. Instead of a controller, a much simpler device is used, whose task is to receive the incoming frame, extract addresses from it and, if the recipient is in the switching table, immediately transfer the frame to the switching matrix. Otherwise, the switch sends a request to the central OpenFlow network controller via a secure channel and, based on the information received, makes the necessary changes to the switching table, after which the switch processes the frame.
The central controller has accurate information about the structure and topology of the network. This allows you to optimize the advancement of personnel and, in particular, to build connections “every with each” at the L2 level, without resorting to IP routing, and, moreover, to pre-switch the data transmission channels all the way from the source to the destination. As a result, not individual frames, but data streams are transmitted over the network.
Details April 5 at 4:00 pm, 2nd Educational Building of Moscow State University, aud. 247 A.
Participation in the seminar is free. To register for the event, please send your full name and contact details to everizhnikova@arccn.ru before 6 pm on 4 April.
