Network performance measurement methodologies in PGMS

Abstract

PGMS (P2P-based Grid Monitoring System) is a Grid monitoring system, which is based on peer-to-peer technology and GMA specification. Network performance measurement is a key component of monitoring system. Always, by all means, many monitoring systems avoid intrusiveness introduced by measurement and interferences between multiple sensors. In PGMS, the basic architecture and function cell is the peer, and some peers constitute a peer group, which is the management cell of PGMS and interconnected by peer-topeer means. The architecture character of PGMS imposes special influences on network performance measurement. Some network measurement methodologies and rough estimate algorithm of bandwidth and delay are presented, which are based PGMS framework. Adaptive control of sensors and on-demand measurement methods are adopted to reduce intrusiveness and interferences, and increase scalability of PGMS. © Springer-Verlag 2004.
