PROMIS: a reliable real-time network management tool for wide area networks

The paper presents the PROMIS tool, a new network management tool based on a distributed architecture of traffic probes. PROMIS allows authorized users to monitor traffic from any WAN segment using a WWW console or a Tcl/Tk graphic interface. In contrast to current network monitoring platforms based in SNMP (Simple Network Management Protocol) or RMON (Remote network MONitor), PROMIS is based on an optimized software architecture that uses a reliable transport protocol (TCP) to provide lossless transmission of monitoring information, thus allowing for real time monitoring irrespective of network load.
