Quality of service guarantee in smart grid infrastructure communication using traffic classification

Abstract

A fundamental requirement for smart grid is the design of a reliable and high performance communication infrastructure. The lack of timely access to information within domains of the smart grid serves as a real limit to detect and effectively react to system instability. Therefore, the delays are an important aspect and should be considered into any power system design or analysis. In this paper, we propose an IP/MPLS based communication infrastructure and optical fiber for the communication medium in the backbone network. In addition, in order to achieve the quality of service required for smart grid applications, traffic flows are classification into four classes using prioritize traffic and appropriate assignment of code point. Then, by using the Traffic Engineering with Diffserv (DS-TE) and active queue management algorithms as well as RIO, the quality of service is guaranteed in an acceptable level.

QoS metrics modeling and analysis for neighborhood area network in smart grid applications

“…In addition, it also can be classified as HD or SD as in our aforementioned definitions. However, the value of Δ r2 has not been noticed in previous works . Hence, this paper first identifies the important of Δ r2 requirement.…”

“…In general, this QoS method is based on the requirements in the electrical applications domain, then maps them to the QoS needs in the telecommunication domain. In the Alcatel‐Lucent QoS document , the authors have used the QoS in VoIP application as the reference source for different service QoS SG.…”

“…In the Alcatel‐Lucent QoS document , the authors have used the QoS in VoIP application as the reference source for different service QoS SG. In Refs , the authors have quantized the QoS SG priority into critical, high, low, and very low levels, and then map them to the existing QoS of the IP. Finally, the authors in Ref.…”

“…Because the SG network is still in the development stage, designing an efficient quality of service (QoS) model dedicated for the SG NAN communication architecture has attracted great attention of researchers. Most of the current SG QoS provisioning models choose the mapping method from the electrical to the telecommunication view. In particular, the expected SG service requirements are based on industry knowledge and electrical engineering judgments.…”

“…In particular, the expected SG service requirements are based on industry knowledge and electrical engineering judgments. Then, they change these demands into a VoIP QoS class or an Internet protocol (IP) class . Unfortunately, their QoSs model only a list the qualitative requirements, and hence they are difficult to be used in SG network planning, designing, and management.…”
