A Shared-Memory Packet Buffer Management in a Network Interface Card

摘要

This paper proposes a dynamic shared-memory packet buffer management algorithm for a protocol processor in a network terminal. The protocol processor is located in a network interface card (NIC). In general, two types of packet buffer management algorithms, static and dynamic, can be used in a NIC; the dynamic buffer management algorithms work better than the static ones for reducing the packet loss ratio. However, conventional dynamic buffer management algorithms do not provide even packet losses to all the applications. Therefore, we propose an algorithm to enhance even packet losses and the proposed algorithm improves the packet loss ratio by 11.80% to 16.70% compared to other conventional dynamic algorithms.
