A Reliable Approach for Transport Session Management

An endpoint’s IP address can become inaccessible due to an interface failure, severe congestions, or due to Border Gateway Protocol’s (BGP) slow route convergence around path outages. In this situation, mission critical applications may require either a fast failure detection or multihoming service. A fast detect failure mechanism allows routing protocols to reroute traffic around problems as soon as they get aware of the link failures. On the other hand, redundancy at the network layer allows a host to be accessible even if one of its IP addresses becomes unreachable. Even though Transmission Control Protocol (TCP) provides some level of reliability for its applications, it does not provide these essential services required for mission critical applications. Accordingly, in this paper, it is investigated main requirements of a session maintenance protocol. Besides, it is presented a reliable approach of transport session management in order to overcome TCP’s shortcoming.
