METHOD AND SYSTEM FOR PROVIDING QOS FOR IN-BAND CONTROL TRAFFIC IN AN OPENFLOW NETWORK

摘要

A method for guaranteeing control traffic throughput in an in-band network configured for delivering control and data traffic, and considering both local and global views of the communication network. The method includes determining an initial configuration for forwarding first control traffic from the packet forwarding device, wherein the initial configuration comprises a first in-band queue for receiving the first control traffic that is delivered over the control path to the controller via a port in the packet forwarding device, and a first bandwidth reserved for the first queue. The method includes performing handshaking with the controller by sending a request to the controller confirming the initial configuration using a network control protocol, and receiving a response from the controller in association with the request. The method includes confirming or modifying the initial configuration based on the response.

1. A computer system, comprising:
a processor configured to:
establish a connection from a packet forwarding device to a controller over a control path in an in-band network configured for delivering control and data traffic;determine an initial configuration for forwarding first control traffic from said packet forwarding device, wherein said initial configuration comprises a first in-band queue for receiving said first control traffic that is delivered over said control path to said controller via a port in said packet forwarding device, and a first bandwidth reserved for said first queue;perform handshaking with said controller by sending a request to said controller confirming said initial configuration using a network control protocol, and receiving a response from said controller in association with said request; andconfirm or modify said initial configuration based on said response.
