The use of Internet Protocol Suite of TCP/UDP in
environments characterized by high delay and high Link Error
rates result in significant degradation of the Protocol
Performance. The DTN Bundle Protocol can be used in such scenarios. Performance evaluation of Delay-Tolerant Network Bundle Protocol in a live network is difficult due to the
absence of networks characterized by extreme environs
