INTRODUCTIONTraffic EngineeringProcess of controlling how traffic flow from one network to another and optimizingresouces utilization and network performance.Why traffic engineering is needed in IP network:Current IGPs always use the shortest path to forward the traffic.MPLS Generally a mechanism in high performance telecommunication networkWhy MPLS: Lack of traffic engineering controlling in the network. MPLS provides increased scalability, manageability, and Quality of Service (QoS) functions to IP-based networks in order to improve traffic engineering.
OBJECTIVES To study on how to Improve traffic engineering in the IP network To study which algorithm that can be completely useful to implement the direction of this project To study on how to utilized the use of paths in the network to avoid over-utilized or underutilized To study on how to solved the congestion problem that exist in the IP network To study on how to apply new technologies – MPLS
PROBLEM STATEMENTTraffic engineering problems in IP network: Uneven distribution of traffic In fowarding the traffic, it causes the traffic congestion on the path and remain other paths over-utilized or underutilized.
LITERATURE REVIEW Papers ‘A Load Balancing Scheme For Congestion Control In MPLS Networks’ describe that the other way to solve the congestion control that exist in Traffic Engineering is by using load balancing scheme. A study by David Culley, Chris Fuchs and Duncan Sharp in their journal entitled An Investigation of MPLS Traffic Engineering Capabilities using CR-LDP compared the performance of the network before and after CR-LDP has been setup.
METHODOLOGY (cont) MPLS Domain
METHODOLOGY (cont)Algorithms deployed in the IP network for trafficengineering controlling: IGP algorithm CR-LDP algorithmSoftware that will be involved in performing thesimulation:a. NS2 (Network Simulator)b. NAM (Network Animator)
METHODOLOGY (cont)Network Scenario:Packets are considered based on their priority withdifferent bandwidth requirement. Set up the LSPs in the MPLS network based on their priority of the packets so that the higher priority will traveled in the shortest path while less priority traveled in longer path of the network. Proposed Model Network
EXPECTED RESULT MPLS enables the traffic engineering in the IP network and that is done essentially by the capabilities of Constraint –based Routing algorithm. (CR-LDP algorithm)
CONCLUSION We can conclude that MPLS has many advantages for traffic engineering. It increases network scalability, simplifies network service integration, offers integrated recovery and simplifies network management, design and operation. Designing suitable algorithm will make better use in improving the traffic engineering throughout the simulations.
