QoS Restoration using a Disjoint Path Group in ATM Networks
نویسندگان
چکیده
A QoS restoration scheme for VP-based ATM network is proposed and its related characteristics are evaluated. The proposed scheme is a state-independent restoration scheme using a disjoint path group. A VP assignment and capacity planning problem using disjoint path group are formulated. When a failure occurs, failed working VPs are switched to protection paths with the same QoS level using a simple and fast restoration algorithm. The simulated restoration characteristics of the proposed algorithm are presented. A scheme of excess capacity assignment to protection path for dynamic traffic demands is also presented and analyzed.

Prioritized traffic restoration in connection oriented QoS based networks
Connection oriented quality-of-service (QoS) based networks offer several service classes each designed to handle connections supporting various types of applications. A network failure will typically result in a large number of disrupted connections in each service class, all of which need to be restored simultaneously. In this paper we propose a distributed fault recovery priority scheme for ...

متن کاملMultipath FEC scheme for the ATM adaptation layer AAL5
One approach to facilitate statistical multiplexing of bursty sources in ATM networks is dispersion of the traffic over independent paths. It has been shown within the literature that by dispersion of traffic over disjoint paths it is possible to increase the Quality of Service (QoS) (see e.g., (Maxemchuck, 1993), (Lee, 1993)). In multipath schemes without additional error control, the resultin...
متن کاملRestoration Strategies and Spare Capacity Requirements in Self-Healing ATM Networks - Networking, IEEE/ACM Transactions on
This paper studies the capacity and flow assignment problem arising in the design of self-healing asynchronous transfer mode (ATM) networks using the virtual path concept. The problem is formulated here as a linear programming problem which is solved using standard methods. The objective is to minimize the spare capacity cost for the given restoration requirement. The spare cost depends on the ...
