For future Internet, network virtualization provides the feasibility of running multiple routing architectures on a shared physical infrastructure. This paper presents the design and evaluation of a bandwidth allocation algorithm based on multi-commodity flow problem solver, which integrated with a traffic predictor. The basic idea of our design is that some failure in the MFP computation implies...
The rapid development of next generation Internet (NGI) and diversity applications make numerous traffic increase. After elaborating drawbacks that traditional MPLS forwarding can not process these enormous traffic, a multipath adaptive forwarding equivalence class (MAFEC) algorithm is proposed. MAFEC can transmit the same-label-traffic into multiple available LSPs (label switch path) and can avoid...
With the rapid increasing of the same destination address traffic, traditional forwarding equivalence class (FEC) can not process these traffic efficiently. After elaborating the drawbacks of single FEC, we propose a variable FEC (VFEC) algorithm and evaluate the algorithm using ns2 simulation. VFEC obtains alternative paths and forwards these traffic to multiple available paths. From the thorough...
Network virtualization provides the feasibility of running multiple architectures on a shared physical infrastructure. Within a virtual network, customized routing protocol can be implemented and deployed in the programmable router. This paper presents the design and evaluation of a service prototype over a virtual network, which provides bandwidth guaranteed multi-path routing with a bandwidth allocation...
The rapid development of next generation network (NGN), communication technology and programming router in the last few years have given rise to a strong research interest in concurrent multipath (CMP) technology. Based on the analysis of flow relation and forward granularity, a novel network layer CMP forward algorithm, CCRF (crosslayer CMP random forward), is proposed. CCRF can classify different...
