One of main feature of next generation of mobile networks is an integration of existing cellular systems with other wireless access technologies. In order to realize a seamless vertical handover (inter-RAT handover) among these different access technologies, a multi-interfaced mobile station is expected to communicate simultaneously on various network interfaces (i.e. to be multihomed) to achieve...
Network processors have exploited many aspects of architecture design, such as employing multi-core, multi-threading and hardware accelerator, to support both the ever-increasing line rates and the higher complexity of network applications. Micro-architectural techniques like superscalar, deep pipeline and speculative execution provide an excellent method of improving performance without limiting...
Meeting the future requirements of higher bandwidth while providing ever more complex functions, future network processors will require a number of methods of improving processing performance. One such method will involve deeper processor pipelines to obtain higher operating frequencies. Mitigation of the penalty costs associated with deeper pipelines have achieved by implementing prediction schemes,...
Ternary content-addressable memory (TCAM) is widely used in high-speed route lookup engines. However, restricted by the memory access speed, the route lookup engines for next-generation terabit routers demand exploiting parallelism among multiple TCAMs. Traditional parallel methods always incur excessive redundancy and high power consumption. We propose in this paper an original TCAM-based IP lookup...
