Flow Admission Control for MPLS Support of DiffServ
نویسندگان
چکیده
In this thesis, an efficient traffic flow admission control mechanism supporting DiffServ is proposed to provide QoS in MPLS networks. We propose a dynamic and flexible flow admission control for MPLS support of DiffServ to prevent the waste of resources. Ingress LSRs may collect information to find out the congested area using control messages exchanged in QoS routing. We exclude the congested LSR from routing decision and LSP aggregation. Thus, the proposed model realizes improved traffic engineering by efficient resource utilization and traffic flow admission control while satisfying the MPLS property of separating control and forwarding.

Real-time voice applications generate network traffic streams that require stringent perconnection performance guarantees in terms of throughput, delay, delay-jitter, and packet lossrate. To guarantee such performance requirements two levels of control are needed: connection admission control (CAC) at the connection level and service discipline at the packet level. These two levels of control c...

متن کاملQoS Support in MPLS Networks
MPLS is sometimes used synonymously with QoS, but more accurately, it is a QoSenabling technology that forces application flows into connection-oriented paths and provides mechanisms for traffic engineering and bandwidth guarantees along these paths. Furthermore, when an MPLS network supports DiffServ, traffic flows can receive classbased admission, differentiated queue servicing in the network...
