An Efficient and Reliable Centralized Connection Management Scheme for Computer Networks

摘要

The Centralized connection management method is vulnerable due to its single point failure and also it requires sufficient buffer and processing speed to handle the requests. To overcome this, we present an efficient and reliable centralized connection management scheme with two central management systems (CMS) for computer networks (ERCC). In ERCC, when a request comes, the odd-numbered requests will be taken up by CMS-1 and also stored in a queue of CMS-2 and vice-versa for the even-numbered requests. If the request-taken CMS cannot allocate a path, then the other CMS will automatically take it up after 't' seconds. It gives a second chance for failed requests. Furthermore, if any one of the CMS fails, other CMS will take over the entire work. By simulation, we showed that our proposed centralized connection management scheme has low blocking probability and processing time in comparison with the single CMS connection management scheme.
