The concept of multi homing is understood based on the IP terminology, since it describes communication node or host as multi homed because it can be accessed by multiple IP address. IP networks in today’s world faces network failure and it needs a time to re-converge themselves to provide a new path. So routing plays a key role in multi homing in order to avoid the failure of paths in the network. Generally Multihoming is designed with TCP Protocol and if provides resilience to the network failures and provides fast recovery with minimum time and during this time the traffic is considered as black holed within the network. Stream controlled transmission protocol is not affected by network re-convergence term since the packet losses are identified immediately and it retransmits through another address based on the routing protocol suggestions. So this SCTP model provides faster recovery and better throughput. This can be implemented in the multiple interface networks to provide multipath communication through multiple IP address. Figure 1.1 illustrates a simple description about multi homing host. It consists of a single host and three interface lines such as N1, N2 and N3 with different IP address to ensure the multi homed model and in the host there will be a unique transport number that uses IP address as IP1, IP2 and IP3.
