This document describes a MAPOS extension, Node Switch Protocol, for automatic node address assignment. MAPOS is a multiple access protocol for transmission of network-protocol datagrams, encapsulated in High-Level Data Link Control (HDLC) frames, over SONET/SDH. NSP automates the HDLC address configuration of each node. Using NSP, a node retrieves its HDLC address from the switch to which it i...

In this note Local Search heuristics are proposed for the problem of minimizing the number of expensive Add-Drop Multiplexers in a SONET or SDH optical network ring, while respecting the constraints given by the overall number of fibers and the number of wavelengths that can carry separate information on a fiber.

In this paper, we present a panorama picture on how to achieve end-to-end video over IP service under the communication environments, consisting of backbone networks, hybrid access networks, and the end users. The paper consists of three equally weighted subtopics which cover some novel thoughts in designing and implementing the video over IP system in the different areas, namely, a Synchronous...

We provide a model and some solution techniques for some problems arising in the design of survivable telecommunication networks utilizing ber optics based techniques Given a set of network nodes and a set of possible links between them we decide where to build links and where to place multiplexers For this architecture to be survivable we use ring architecture combined with point to point dive...

The impetus focus is on to provide high data transfer and utilization of high bandwidth, so the era of computer networks completed a journey from co-axial, twisted pairs cables to optical cables migrating from SONET/SDH to WDM technology based networks. This paper deals with various aspects concerned to WDM based networks in context to failure of fiber links in WDM optical networks and the surv...

SONET/WDM networks using wavelength add–drop multiplexing can be constructed using certain graph decompositions used to form a “grooming,” consisting of unions of certain primitive rings. The existence of such decompositions when every pair of sites employs no more than 8 of the wavelength capacity is determined, with few possible exceptions, when the ring size is a multiple of four. The techni...
