Abstract:
Service chaining is the concept of applying an ordered set of
services to a packet or a flow. Services in the chain may
include network services such as load-balancing, firewalling,
intrusion prevention, and routing among others. Criteria for
applying a service chain to a packet or flow can be based on
packet/flow attributes that span the OSI layers (e.g., physical
port, Ethernet MAC header information, IP header information,
Transport and application layer information). This document
describes use cases and I2RS (Information to the Rousting
System) requirements for the discovery and maintenance of
services topology and resources. It also describes use cases
and I2RS requirements for controlling the forwarding of a
packet/flow along a service chain based on packet/flow
attributes.
