Chapter XXIII. Traffic Management

Introduction

Traffic Management capabilities built-in to Chelsio adapters can shape transmit data traffic
through the use of sophisticated queuing and scheduling algorithms built-in to the ASIC hardware
which provides fine-grained software control over latency and bandwidth parameters such as
packet rate and byte rate. These features can be used in a variety of data center application
environments to solve traffic management problems.
Traffic Management features in Chelsio's adapters allow the user to control three main things:
•
Guarantee low latency in the presence of other traffic
•
Control max bandwidth that a connection or a flow (a group of connections) can use
•
Allocate available bandwidth to several connection or flows based on desired levels of
performance
Once the offload transmit traffic shaping classes have been configured, individual offloaded
connections (flows) may be assigned to a traffic shaping class to manage the flows as per the
class configuration. The mechanism to accomplish this "flow to class" mapping assignment is the
Connection Offload Policy (COP) configuration system.
