Buffer Management and Scheduling for Enhanced Differentiated Services
نویسندگان
چکیده
A novel framework, called JoBS (Joint Buffer Management and Scheduling), is presented for reason-ing about relative and absolute per-class service differentiation in a packet network without informationon traffic arrivals. JoBS has two unique capabilities: (1) JoBS makes scheduling and buffer managementdecisions in a single step, and (2) JoBS supports both relative and absolute QoS requirements of classes.JoBS is presented in terms of the solution to an optimization problem. Numerical simulation examples,including results for a heuristic approximation of JoBS, are presented to illustrate the effectiveness ofthe approach and to compare JoBS to existing methods for loss and delay differentiation.

Quality of Service (QoS) refers to a set of rules or techniques that help the network administrators use the available network resources optimally to manage the effects of congestion and to treat the applications according to their needs. The differentiated services architecture (DiffServ) allows providing quality of service to users. The major DiffServ premise is that individual flows with sim...

This paper proposes a method for scheduling and buffer management in differentiated services networks which is based on JoBS algorithm. JoBS differentiates traffic classes base on delay and loss rate. Furthermore, it supports both relative and absolute constraints. Nowadays with the expansion of Internet traffic and its diversified service requests, the focus is on requirement of new traffic us...

متن کاملA Core-Stateless Buffer Management Mechanism for Differentiated Services Internet
The IETF differentiated services (DiFerv) framework achieves scalability by moving complexity out of the core of the network into edge routers which process fewer number ofjlows. Recently, an end-to-end service called the premium service (PS) has been proposed under the Dimerv model to provide coarse grained guaranteed rate service. This paper presents a buffer management mechanism based on sim...
