Traffic engineering (TE) is an efficient tool for optimizing traffic routing and balancing the flows in networks. Traffic is dynamic, previous TE optimization over a single traffic matrix (TM) have some limitations, because a single TM can have big measurement errors and is insufficient to depict the traffic flucuations. Thus, we consider using multiple TMs to overcome these limitations. With the...
Traffic engineering is a method to balance the flows and optimize the routing in the network. Software defined networking is a new network architecture and we can gain great benefit by migrating the traditional IP network to the SDN-enabled network from the perspective of traffic engineering. However, due to the economical, organizational and technical challenges, migrating to the network with a full...
Traffic engineering under OSPF routes along the shortest paths, which may cause network congestion. Software Defined Networking (SDN) is an emerging network architecture which exerts a separation between the control plane and the data plane. The SDN controller can centrally control the network state through modifying the flow tables maintained by routers. Network operators can flexibly split arbitrary...
Border Gateway Protocol (BGP) is the de facto standard protocol for the inter-domain routing. Due to multi-homing and traffic engineering, the BGP routing table size of default free zone (DFZ) is growing rapidly. Inter-domain routing is facing the scaling challenge. Many solutions have been proposed. Among them, the core-edge separation scheme gets more attentions than others due to its practical...
Internet routing system is the fundamental components of Internet. As the Internet growth, Internet routing system is facing the scaling issues of global routing table expanding due to the wide use of multi-homing, traffic engineering, and mobility. Existing proposed solutions need to change host protocol stack or routing architecture, hence, no incentive for practical deployment. In this paper, we...
BGP is the de facto standard protocol for the inter-domain routing. Due to multi-homing and traffic engineering, the BGP routing table size of default free zone (DFZ) is growing rapidly. Inter-domain routing is facing the scaling challenge. Such routing scaling issue has being concerned by research community and IETF, and many solutions have been proposed. Among them, the core-edge separation scheme...
