Lucent Technologies 5ESS - Multihoming

Multihoming
....................................................................................................................................................................................................................................
Overview
Multihoming has the added advantage of providing multiple paths in
the IP network thus increasing the reliability. In the 5E-XC
™
implementation, supporting multihoming requires two IP addresses per
endpoint. In order to take advantage of the multihoming capability, the
customer’s IP network must be engineered in such a way that packets
routed using the two IP addresses traverse different physical paths in
the network.
Note: Diverse IP routing only applies when multi-homed SCTP
endpoints are used to transport SIP messages. UDP does not support
multi-homing.
