A smart heuristic for relieving RBB in dependable transmission environment

摘要

Wireless access technologies had effectively accelerated the evolution of Internet and enhanced the overall capacity of networks. However, due to the complexity of multiple paths in mobile scenarios, the managements of network and terminal are more and more challenging. For instance, when disordered packets arrive at the destination, they have to be stored within the transport layer buffer at the receiver side, which may seriously restrict the transmission performance. We present a smart heuristic to handle and relieve such Receive Buffer Blocking (RBB) issue in dependable environment. A novel modeling approach for describing the properties of RBB is also presented by selecting “Theoretical maximum of disordered packets” as the target. Both loss free and loss occurs circumstances are considered comprehensively. The functionality of our scheme is confirmed via mathematical perspective based on the proposed model. The reasonable treatment method for one way delay and packet loss during the scheduling policy design are also discussed.
