JoBS: Joint Buffer Management and Scheduling for Differentiated Services

نویسندگان

  • Jörg Liebeherr
  • Nicolas Christin
چکیده

A novel algorithm, called JoBS (Joint Buffer Management and Scheduling), is presented for loss and delay differentiation of traffic classes in a packet network. JoBS has two unique capabilities: (1) JoBS makes scheduling and buffer management decisions in a single step, and (2) JoBS supports both relative and absolute QoS requirements of classes. The JoBS algorithm 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 of the approach and to compare JoBS to existing methods for loss and delay differentiation. Keywords— Buffer Management, Scheduling, Service Curves, Quality-of-Service, Service Differentiation.

Buffer Management and Scheduling for Enhanced Differentiated Services

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 ...

A Novel Fuzzy Logic Base Scheduling Mechanism for Service Differentiation in IP Networks

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...

Rate allocation and buffer management for differentiated services

A novel algorithm for buffer management and rate allocation is presented for providing loss and delay differentiation for traffic classes at a network router. The algorithm, called JoBS, provides delay and loss differentiation independently at each node, without assuming admission control or policing. Contrary to most existing algorithms, scheduling and buffer management decisions are performed...
