Flexible Traffic Splitting in OpenFlow Networks

摘要: Traffic engineering (TE) functionality aims to control and fine-tune the routing configuration bandwidth allocation in order optimize use of network resources avoid build-up congestion. The performance a given TE scheme is, however, strongly influenced by degree flexibility offered distributing traffic load. Multipath coupled with arbitrary splitting are two essential ingredients for achieving desired flexibility. Current proposals multipath OpenFlow have mostly focused on equal solutions, which impose limitations terms level that can be achieved. In this paper, we investigate new approach, exploits properties bit-masking operations enable flexible networks. proposed solution relies matching entry feature multiple table pipeline capability OpenFlow, as such, is line current standard. Based empirical evaluation, illustrate influence considered masking parameters how these configured achieve ratios. results demonstrate our similar accuracy one obtained hash-based approach. However, contrast proposals, it does not require complex extensions protocol easily implemented an environment.
