label switching technology is a flexible and high performance method for forwarding layer three packets that are mapped to layer two flows. each label switch router, lsr, needs a specific label for every flow, where the number of labels depends on the mapping and granularity of flows. data and control driven methods are the most significant and popular methods in label mapping policy. the above...

Generalized multiprotocol label switching, also referred to as multiprotocol lambda switching, supports not only devices that perform packet switching, but also those that perform switching in the time, wavelength, and space domains. The development of GMPLS requires modifications to current signaling and routing protocols. It has also triggered the development of new protocols such as the Link...

In response to the need for higher flexibility in optical networks, a Generalised Multi-Protocol Label Switching (GMPLS) protocol suite is currently under standardisation. However, in these standards a Label Switched Path (LSP) hierarchy is defined that only considers circuit-switched optical networks. This paper aims at broadening the scope of this hierarchy to more advanced optical networking...

In order to provide reliable connections across metropolitan and wide-area optical networks, the network operator must provide some degree of redundancy so that traffic can be switched from damaged working paths to backup paths that are disjoint from the working paths that they are protecting. In the most general form of path protection, N working paths between two client edge nodes are protect...

Most of the initial efforts to utilize Generalized MPLS (GMPLS) have been related to environments hosting devices with a single switching capability. The complexity raised by the control of such data planes is similar to that seen in classical IP/MPLS networks. By extending MPLS to support multiple switching technologies, GMPLS provides a comprehensive framework for the control of a multi-layer...
