Re: [openflow-discuss] Pantou on WRT54GL

Eder (the person who implemented OF 1.3 and ported it to OpenWRT) is pretty busy right now, so I ask you to please read the instructions and try them out first before asking for his help. Please note that the implementation has some RAM and CPU requirements, so it won´t run on any WiFi device. Our

Re: [openflow-discuss] Flow setup rate in production network

2013-09-24 Thread Marcos Rogerio Salvador
Current controllers (e.g., Beacon) can handle millions of packet-ins/flowmods per second, the bottleneck is in the switches, which can handle hundreds to thousand or so packet-ins/flowmods per second. So depending on the network scenario switches may not cope with the bursts of packet-ins/flowmods.

Re: [openflow-discuss] Routing over openflow networks

2013-09-12 Thread Marcos Rogerio Salvador
I suggest you take a look at RouteFlow, a software solution that combines open source Linux routing stacks with OpenFlow controllers to transform OpenFlow switches onto IP routers: http://cpqd.github.io/RouteFlow/ -Marcos 2013/9/12 David Alejandro Montano Restrepo > Hello, > My name

Re: [openflow-discuss] SDN & Routing Protocols

2013-05-20 Thread Marcos Rogerio Salvador
Besides, in many scenarios/applications the idea of replacing the entire network with a new OpenFlow one is unlikely, which means that your OpenFlow switches will still have to interoperate with non-OpenFlow switches. This is why we decided to develop RouteFlow, a migration path towards SDN. http:

Thank you Bill for the pointer to CPqD´s OF 1.2. By the way, I don´t know the reasons for you to choose OF 1.2, but we have also developed OF 1.3 and associated tools, in case that could also meet your requirements. They are all available here on github: http://cpqd.github.com/ofsoftswitch13/ []

Depending on what you want to do you can do it with today´s version of NetFPGA. For instance, if you don´t really need QoS enforcement at data path level for now NetFPGA + FlowVisor should do. []s Marcos 2012/8/23 Cong Wang : > hi all, > I'm studying Openflow switch on NetFPGA implementa

If you think of GMPLS, where GMPLS protocol entities run as virtual entities on servers or in (most probably private) clouds to control traffic forwarding (through LSPs) in GMPLS-incapable nodes, that is a case of a non-OF SDN architecture. Take DRAGON as an example. Comercial GMPLS stacks can run
