This work deals with routing schemes in SDH/SONET-WDM multilayer networks applying Synchronous Digital Hierarchy (SDH) or Synchronous Optical Network (SONET) on top of a dynamic photonic network in Wavelength Division Multiplex technology (WDM). The focus are integrated routing schemes which benefit from an integrated view of the SDH/SONET layer and the optical layer. Besides the comparison of ...

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects for modeling Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) circuits over a Packet Switch Network (PSN). Information about the current status of this document, any errata, and how to provide f...

Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract The Generalized Multi-Protocol Label Switching (GMPLS) suite of protocols has been defined to control different switching technologies and different applications. These include support for requesting Time Division M...

or High capacity backbone mesh network (Synchronous Optical Network/Synchronous Digital Hierarchy) a multipath provisioning system has been investigated and designed. The algorithm is suitable for the VCAT like issues. The work has been done to support the SONET/SDH network using the dedicated path protection and Shared Path protection schemes. The enhancement has been done in the Dedicated and...

Oscillators based on the SAW (surface acoustic wave) technology in general offer lower noise compared to the conventional crystal oscillators at higher frequencies. VCSO (voltage-controlled SAW oscillator) can be an important component in the phase lock loop (PLL) subsystem for clock and data recovery (CDR), clock smoothing or frequency translation in the SONET/SDH (Synchronous Optical Network ...

In this paper, the model of clock timing signal is first introduced, together with some basic quantities defined in telecommunications timing applications. Moreover, the time-domain quantities defined in ETSI and ITU-T standard bodies, for telecommunications clock stability specification, are listed and their standard estimators, recommended for time and frequency measurements, are provided. A ...

A new method that uses round-trip paths to accurately measure transmission delay for time synchronization is proposed. The performance of the method in Synchronous Digital Hierarchy networks is discussed. The feature of this method is that it sepamtely measures the initial roundtrip path delay and the variations in round-trip path delay. The delay generated in SDH equipment is determined by mea...
