ATM Transmission Convergence implementations : SONET / SDH vs . Cell - Based
نویسندگان
چکیده
This article discusses various issues around the Transmission Convergence (TC) sublayer in the physical layer of ATM. A brief introduction is given to the layered approach and functionality of the ATM physical layer. This is followed by an introduction to the two main TC sublayer implementations for ATM at high line rates, namely the SONET or SDH option and the CellBased option. These options are then contrasted and evaluated for the 622.08Mbps implementation. Such an evaluation is critical in deciding between the two options.

The Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) [1][2][3][4] family of ITU-T standard protocols are designed to provide common, simple, and flexible interface for broadband optical fiber transmission systems. It enables direct octet-synchronous multiplexing of lower rate tributaries. SONET/SDH-compliant transmission systems are widely deployed by telephone carriers wor...

Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) are very closely related standards, which came into being primarily as a means of transporting telephone traffic in large volumes utilizing optical fiber transmission systems. SONET was brought forth by Bellcore (Telcordia), with coordination from International Telecommunication Union (ITU) as well as other standards or...

The Point-to-Point Protocol (PPP) [1] provides a standard method for transporting multi-protocol datagrams over point-to-point links, and RFCs 1662 [2] and 2615 [3] provide a means to carry PPP over Synchronous Optical Network (SONET) [4] and Synchronous Digital Hierarchy (SDH) [5] circuits. This document extends these standards to include a new encapsulation for PPP called Simple Data Link (SD...

This document describes a historical method for encapsulating Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) Path signals for transport across packet-switched networks (PSNs). The PSNs explicitly supported by this document include MPLS and IP. Note that RFC 4842 describes the standards-track protocol for this functionality, and new implementations must use RFC 4842 rather...
