A prototype SNMP management framework for DiffServ Linux Routers, its implementation and performance

Abstract

In Linux Router management, the Traffic Control tool is still the unique method provided to network managers for monitoring and configuration. Scripts invoked through telnet are used for this purpose. Router monitoring is obtained by parsing the report created from the tc show command. This leads in significant load for the management system imposing barriers for real time and dynamic management. The purpose of this paper lies in presenting a prototype implementation of the DiffServ MIB based on the Traffic Control API. The fundamental objective of this implementation is to provide an SNMP management framework for DiffServ Linux Routers. It is shown that, on the basis of the SNMP functionality, efficient and real-time management can be obtained, enabling the introduction of relative differentiated services. © 2003 by Springer Science+Business Media New York.
