GMPLS grew out of MPLS, a packet-switching technology designed to improve the efficiency of data networks. In this paper, we discuss the GMPLS technology, analyze its application. GMPLS is an advanced protocol which is essential for managing a diverse and complex network, because service deployment and service provisioning are manual, lengthy and costly processes. GMPLS has caused technical challenges...
Wavelength-division multiplexing (WDM) is the best technology currently available to handle the rapidly increasing demand for bandwidth in fiber-optical telecommunications networks. This paper analyzes WDM transport network and discusses GMPLS technology for WDM network. Today, WDM optical transport networks have become more complex over the years and have extended into the metropolitan areas closer...
In recent years, IP over WDM has become a key technology of choice for meeting the tremendous bandwidth demand in the optical infrastructure. Survivability is an emerging discipline that blends optical network security with business risk management for the purpose of protecting highly distributed information services and assets. No system is totally immune to attacks, accidents, or failures. Therefore,...
In recent years, there have been dramatic changes in the character of security problems, in their technical and business contexts, and in the goals and purposes of their stakeholders. As a consequence, many of the assumptions underlying traditional security technologies are no longer valid. Failure to recognize the depth and breadth of these changes in combination prevents effective solutions to modern...
Generalized multi-protocol label switching (GMPLS) is being developed by the IETF as the industry standard for transport network control planes. GMPLS defines IP based control of optical resources. Routers are expected to deliver advanced services at higher throughput while handling large amounts of label switching path (LSP) creation/deletion, traffic engineering link information exchange, and link...
The huge demand for communication network has tend to make topologies of optical networks based on wavelength division multiplexing (WDM) complex. This article proposes a new approach for optical communication network with GMPLS technology in WDM networks. GMPLS grew out of vanilla MPLS, a packet-switching technology designed to improve the efficiency of data networks. A flavor of MPLS, known as MPLS-TE,...
