Scalability of inter-domain edge tunnels using bandwidth brokers: a region-based approach
نویسندگان
چکیده
In this paper we present a scalability study on interdomain tunnels using Bandwidth Brokers. Our approach is based on collections of Autonomous Systems called regions.We analyzed our architecture through simulation. Our analysis results show that scalability of the approach depends on the size of the regions, and as the size of the region decreases, scalability of the approach increases.We show that our architecture increases state scalability as well as signaling scalability for Diffserv networks.

Design of a Minimal Signaling Based Bandwidth Brokering Protocol
The DiffServ architecture uses automated agents known as Bandwidth Brokers for provisioning, allocating and managing QoS resources within domains as weil as communicating with agents of other domains so that QoS guarantees can be provided across domains. The Bandwidth Brokers attempt to establish an end-to-end Quality of Service through signaling between each other. This leads to an implicit tr...
متن کاملClass of Service Concepts in Autonomous Systems
The bandwidth broker architectures introduced to manage diffserv still have scalability flaws in the mean of large volumes of end-to-end tunnels and workload they have to handle. In addition they only provide solutions of inter-domainmanagement and do not consider the characteristics of intra-domain-management. The new signaling approach for intra-domain-management presented in this paper utili...
متن کاملInter-Domain Traffic Engineering on a Bandwidth Broker Supported Diffserv Internet
In this paper, we are proposing an Inter-domain traffic engineering architecture over a Bandwidth Broker (BB) supported Diffserv internet. The main components of our architecture are a novel inter-domain QoS routing architecture, the addition of an explicit path setup capability to the Simple Inter-domain Bandwidth Broker Signaling (SIBBS) protocol, and inter-domain label switched path (LSP) se...
متن کاملArchitectures and performance evaluation of bandwidth brokers
DiffServ is the basis of contemporary QoS-enabled networks. Setting up DiffServ QoS requires extensive engineering effort in dimensioning and provisioning, especially for adjacent networks under different administrations linked in a “federated” hierarchy. The bandwidth broker is an entity that is responsible for the management of the resources and the QoS service operation in an automated way. ...
متن کاملService Level Agreement Trading for the Differentiated Services Architecture
Bandwidth brokers as proposed in the diffserv framework build on the process of setting up Service Level Agreements (SLA). This is a very static procedure, usually performed manually and based only on a simple description of the SLA. However, diffserv is suited to handle a more dynamic environment and to provide more than connectivity with its service classes. Our proposal enhances bandwidth br...
