“…An important aspect that must be considered is that COPS-PR messages are usually binary-encoded following the Basic Encoding Rule [6], as well as the PIB modules are described in documents ruled by the Structure of Policy Provisioning Information (SPPI) [7]. These two features are important because they differ from the ones found in NETCONF.…”

Although COPS-PR is a policy management protocol already found in commercial network equipments, the IETF has been also working on the standardization of the NETCONF protocol, which can be seen as a competing solution when employed for QoS management. NETCONF seems to have the potential to become a feasible alternative to the established management protocols (e.g., SNMP), but few is known about its behavior and performance when it is used together with COPSPRo In this paper we present and evaluation of NETCONF and COPS-PR in a management environment for DiffServ-enabled networks. NETCONF to COPS-PR gateways have been developed in order to integrated COPS-PR commercial equipments into networks managed via NETCONF-capable management stations. Through such gateways a set of evaluations have been performed in order to draw the picture of integrated NETCONF and COPS-PR for QoS management. The results presented in this paper can help network operators in selecting adequate management setups, as well as provide guidelines for the improvement of NETCONF.

On the future of internet management technologies

2003

View full text Add to dashboard Cite

As the Internet continues to grow, it becomes more and more apparent that existing Internet management technologies need to be improved, extended or replaced in order to extend functionality and reduce development time and operational costs. Within the IETF, IRTF, and IAB, several new approaches are currently under discussion. Evolutionary approaches aim at improving currently used technologies, whereas revolutionary approaches try to replace existing management-specific technologies with standard distributed systems technologies. This article surveys the research and development work under way to develop future Internet management technologies.

“…The Internet Engineering Task Force (IETF) is working on the standardisation of PBNM technologies such as the Common Open Policy Service protocol for Policy Provisioning (COPS-PR) (Chan et al, 2001) and its associated data definition language, the Structure of Policy Provisioning Information (SPPI) (McCloghrie et al, 2001). COPS-PR messages are usually encoded according to the Basic Encoding Rules (BER), a binary encoding scheme.…”

Policy-Based Management of Diffserv Using XML Technologies

A design, implementation, and evaluation of a Policy-based Management framework for DiffServ networks using XML technologies is presented. XML is used for policy representation throughout the entire policy life cycle, as well as in the communication protocol, reducing development costs, while promoting clarity, simplicity, and interoperability. Furthermore, performance evaluation results show that the proposed scheme generates less network traffic than its COPS-PR counterpart when protocol messages are compressed. Moreover, XML messages generate higher processing delays. The added processing overhead caused by compression to XML messages is very small, thus the gains in reduced network traffic generated outweigh the losses in terms of processing delays.
