QoS for Aggregated Flows in VPNs
نویسندگان
چکیده
: Aggregation of flows is a natural consequence of the transition of flows across multiple network domains. The quality of service that is provided to an aggregated flow is dependent on a sufficient set of individual flow characteristics correctly transformed in to the aggregated flow characteristics. VPN routers at the boundary of the private networks encrypt information within the data packets of a flow and flow characteristics are no longer visible to the interface domain. This document describes the challenges faced by QoS mechanisms to provide quality of service to secure aggregated flows.

Building MPLS VPNs with QoS Routing Capabilty
Recently MPLS is used for building up VPNs in IP backbone, called MPLS VPNs. In this paper, we discuss issues on finding routes with QoS requirements (i.e., QoS routing) in MPLS VPNs. We first present background on MPLS VPNs as well as QoS routing. Then we discuss both the benefits and problems resulted from introducing QoS routing into MPLS VPNs. We particularly present an architecture of MPLS...
متن کاملA 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...
متن کاملSwitchlets and Resource-Assured MPLS Networks
MPLS (Multi-Protocol Label Switching) is a technology with the potential to support multiple control systems, each with guaranteed QoS (Quality of Service), on connectionless best-effort networks. However, it does not provide all the capabilities required of a multi-service network. In particular, although resource-assured VPNs (Virtual Private Networks) can be created, there is no provision fo...
متن کاملAdaptive marking for aggregated flows
Abstract— The differentiated services architecture is receiving wide attention as a framework for providing different levels of service according to a service profile in the Internet. The current architecture allows aggregated flows sharing a service profile. This paper looks at the problem of achieving specific QoS goals of individual flows by flexibly managing resources available to an aggreg...
متن کاملResource Allocation for Quality of Service Provision in Buffered Crossbar Switches with Traffic Aggregation
The capability of providing quality of service (QoS) in packet switches of computer networks is critical to implementation of distributed multimedia systems. The buffered crossbar switching architecture is promising to achieve high performance without complex implementation. In this paper, we study the problem of resource allocation to aggregated traffic classes in buffered crossbar switches fo...
