QoS assurance in Smart Grid for IP-based applications of Mashhad Electric Energy Distribution company

Nowadays, the increasing demands and inadequate technology in electricity industry lead us to make it smart. To achieve this goal, the quality of service is very important for critical applications like teleprotection. Since the allowed delay for these kinds of applications are about milliseconds, having latency in packet delivery will cause serious damages. In this paper, we try to identify the verity of IF-based applications in Mashhad Electric Energy Distribution Company (MEEDC) and prioritize them based on their importance and traffic features such as allowed delay, arrival rate and packet size. After that we want to find an appropriate aggregation point for their traffics to analyse the input queue of the routers. By doing this we will be able to calculate the minimum required bandwidth for the egress link and according to the available communication network we can make decision whether the egress link is adequate or not. If not we can guarantee the QoS for critical applications.
