Analysis of TCP performance over the PBB-TE during the protection switchover time

Adapting to meet service requirements to users and growth of market in factory automation and health control equipments, network environment is rapidly changing into the reliable and high-quality Internet. TCP is expected to be a solution of the reliable transport protocol. The carrier class transport network is also expected as a solution of the underlying transport network which supports high availability with 50 ms resilience time. This paper analyzes the impact of protection switching on TCP performance over the Provider Backbone Bridge Traffic Engineering (PBB-TE) network. Our experimental results suggest TCP protocol expected to be set Retransmission Timeout (RTO) to 50 ms or depending on the circumstances of the underlying transport network.
