SLS to DiffServ configuration mappings

چکیده
This document addresses the problem of mapping Service Level Specifications (SLS) to IP Differentiated Services (DiffServ) configuration. We introduce a two step mapping controlled via a policy-based management system. The two step mapping includes the service specification to intra-domain service mapping (Per-Domain Behavior (PDB) [PDB-DEF]) and the further mapping to the DiffServ mechanism available in the domain. The first step uses an Ndimensional room (e.g. including delay/jitter, loss and throughput) to classify the SLS into a limited set of available intra-domain services. Based on this classification, assignment of the service class, and per service class admission control is performed. The mapping is implemented on top of a QoS configuration API using a Linux-based DiffServ implementation.

An End-to-End QoS Adaptation Architecture for the Integrated IntServ and DiffServ Networks
In this paper, we propose an end-to-end quality of service (QoS) adaptation network architecture to guarantee service qualities for mobile users, according to user requirements and available network resources on the end-toend path which is across the wired backbone DiffServ network and wireless IntServ networks. Further, we adopt the bandwidth broker (BB) for resource allocations and COPS-SLS p...
متن کاملINTERNET - DRAFT IBM DiffServ Implementation Experience June 1999
This informational memo contains a description of some measurements from early DiffServ (DS) experiments that used a preliminary version of IBM's DiffServ implementation on an IBM router over an egress T1/E1 PPP interface. The service level specification (SLS) may be configured on the router or optionally controlled by an external LDAP policy server. The measurements were intended to examine th...
متن کاملDiffServ Management on Mobile IP Networks using COPS-PR
This paper describes and evaluates a framework for managing Differentiated Services (diffserv) configuration on Mobile IP-based networks. In the considered scenario, users can keep their QoS privileges while they move along through different access networks interconnected by a diffserv domain. In this case, the edge routers receive the diffserv configuration dynamically, according to the authen...

متن کاملOn the Use of Rate Configuration in the Interoperation between DiffServ and 802.11e EDCA
This paper investigates rate configuration of the Expedited Forwarding (EF) class of Differentiated Services (DiffServ) when used with 802.11e EDCA. The rate configuration problem is presented, and several approaches are tested and evaluated in order to solve the problem. Results reveal that the contention window makes rate configuration very hard for the highest priority class (AC_VO) in 802.1...
