An Enhanced Dynamic Packet Buffer Management

Abstract

A packet buffer for a protocol processor is a large shared memory space that holds incoming data packets in a computer network. This paper investigates four packet buffer management algorithms for a protocol processor including dynamic algorithm with different thresholds (DADT), which is proposed to reduce the packet loss ratio efficiently. The proposed algorithm takes the advantage of different packet sizes for each application by allocating buffer space for each queue proportionally. According to our simulation results, the DADT algorithm works well in reducing packet loss ratio compared to other three algorithms.
