Carrier ethernet network operation scenario and the assessment of control cycle duration

Abstract

Objective: To develop a formalized algorithm of carrier class network Carrier Ethernet operation and, by means of the latter, obtain an assessment of control cycle duration for intelligent control system (ISU) of the network in question. The given operation scenario is different from those currently in use by an account of processes of the new generation Carrier Ethernet network, failures’ identification and reconstruction of network elements by means of core control technologies of elements’ status (OAM technologies) and application of statistically defined change traffic (distributive laws) of Carrier Ethernet network elements’ status. Methods: In order to achieve the objective in question the following methods were applied: signature method, statistical method and neural networks. Results: The building principles of Carrier Ethernet network were presented and its OAM architecture was formed. In accordance with the analyzed types of Carrier Ethernet network connections and failure control mechanisms on the basis of OAM, control process and Carrier Ethernet network operation scenario was developed. Practical importance: The obtained operation scenario of the new generation network and the assessment of ISU control cycle of Carrier Ethernet network makes it possible to formulate the requirements to perspective operation system, whereas the assessment result of Carrier Ethernet network operation cycle duration allows one to determine probabilistically time response characteristics of network functioning and assess the input of different subprocesses in the total process time. The presented building principles of Carrier Ethernet network make it possible to solve the task halfway, which is aimed at the necessity of building a unified methodological basis for the formation of perspective operation system for the network in question.
