Distributed remote monitoring (dRMON) of network traffic and performance uses distributed nodes to collect traffic statistics at distributed points in the network. These statistics are forwarded to collectors which compile the statistics to create combined views of network performance. A collector may mimic a prior art, non-distributed, network probe and may interact with network management software as though it were a stand alone network probe thereby simplifying a user's interaction with the distributed system. The invention is designed to work in accordance with a variety of standard network management protocols including SNMP, RMON, and RMON2 but is not limited to those environments. The invention has applications in a variety of communication system environments including local area networks, cable television distribution systems, ATM systems, and advanced telephony systems. A specific embodiment of the invention solves is particularly optimized to work in LAN environments with end systems running under Windows-compatible network operating systems.

[ What is claimed is:] [1.] A method for distributed collecting of network statistics comprising:gathering network statistics at a plurality of nodes distributed in a network;transmitting data containing said statistics to a collector;combining said statistics from said plurality of nodes into group network statistics to form complied statistics;reporting network performance data based on said compiled statistics, from said collector, to a network manager; andwherein multiple nodes each respond to a multicast poll data unit from a collector and flooding of the collector is prevented by having each node delay its response by a random value.
