APPLICATION LAYER ANYCAST
Miklós Berzsenyi, István Vajk, Hui Zhang · 1999
In this paper, we present a new approach to application layer anycasting. The key to anycast is making it possible for clients to efficiently find the ‘best ’ server for a given application in an unknown group of servers. The anycast service makes a wide range of new multimedia applications possible, and will be part of future integrated services networks. We designed a selective anycast protocol, which is aimed at picking the right server based on application specific metrics, such as network delay and server load. This paper considers server-choosing metrics and efficient mechanisms to compute these metrics. We also present simulation results, which show our approach’s merit, and proves that anycast can significantly improve the performance as compared to the traditional methods.
