ATM Adaptation Layer



• The ATM Adaptation Layer (AAL) defines the rules for breaking up a higher level protocol data unit (PDU) into ATM cells for transmission on the network, and for reassembling the PDU at the other end
AAL Services
• Handle transmission errors
• Segmentation/reassembly (SAR)
• Handle lost and misinserted cell conditions
• Flow control and timing control
AAL Protocols
• AAL layer has 2 sublayers:
o Convergence Sublayer (CS)
Supports specific applications usin ....etc

Dual-Link Failure Resiliency Through Backup Link Mutual Exclusion

Abstract”
Networks employ page link protection to achieve fast recovery. While the first page link failure can be protected using page link protection, there are several alternatives for protecting against the second failure. This paper formally classifies the approaches to dual-link failure resiliency. One of the strategies to recover from dual-link failures is to employ page link protection for the two failed links independently, which requires that two links may ....etc

Layer Reassignment for Antenna Effect Minimization in 3-Layer Channel Routing


Abstract

As semiconductor technology enters the deep submicron em, reliability has
become a major challenge in the design and manufacturing of next generation
VLSI circuits. .ln this paper we focus on one reliability issue - the antenna
effect in the context of s-layer channel routing. We first present an antenna effect
model in Z-layer channel routing and, based on this, an antenna effect cost
function is proposed. A layer ....etc

ATM

ATM is simply a Data Link Layer protocol. It is asynchronous in the sense that the recurrence of the cells containing information from an individual user is not necessarily periodic. It is the technology of choice for evolving B-ISDN (Board Integrated Services Digital Network), for next generation LANs and WANs. ATM supports transmission speeds of 155Mbits / sec. In the future. Photonic approaches have made the advent of ATM switches feasible, and an evolution towards an all packetized, unified, broadband telecommunications and data comm ....etc
