| Popis: | Connection provisioning with survivability has become very critical in optical networks in order to meet the increasing bandwidth requirements of applications. Shared path protection is a promising technique to provide survivability in network, but this technique also suffers from some redundancy in network. In this paper we have surveyed algorithms that support provisioning of connections with shared path protection and mixed shared path protection. Different connection provisioning strategies have been compared with respect to complexity and blocking probability. This paper focuses on exploiting the knowledge of holding time of connections to make an advance reservation of connection request in a given larger window, which will reduce blocking for future connections. For this purpose paper we proposed an enhancement in HT-AGSDP algorithm [1], that already exploit the knowledge of connection holding time in making choice of primary and backup path connection. |
