Research Of Traffic Matrix Modeling And Application In Forces Architecture Router

Traffic matrix can completely describe the distribution of all traffic requirements in the network, combining with the network routing information, it can also clearly reflect the composition of the flows on the links, and is the key input to network management and traffic engineering task. This is the first time that introduces the concept of the traffic matrix into ForCES architecture routers, through the angle of internal flow measurement of ForCES router to monitor the operation of routers, and optimize the ForCES router’s internal flows on the estimated flow information of ForCES router in order to balance the flows on all of the links in the internal of router.ForCES architecture separates the forward element (FE) and control element (CE), they communicate by the standard protocol of ForCES, control element runs varies of software applications, such as SNMP protocol software, OSPF protocol software, forward element is composited of unified logic function block (LFB). The essence of ForCES architecture is that it separates the network components of software and hardware in the structure,and make the interface between CE and FE, and intenal modules of FE standardized, thus make the designation of network components as a process of reconstructing FE and LFB in FEAccording to the topology of FEs in ForCES architecture and analysize the characteristics of traffic matrix estimation methods, we decide to use the gravity model to estimate all the traffic demand of FEs, and analysize the estimation accuracy. By analyzing a variety of route optimization algorithm based on the traffic matrix, we decide to use the negative valence ring algorithm to calculate the set of route optimization, through optimize high traffic load links, we can make the balance of traffic on each link.
