An Efficient Link Bundling Transport Layer Protocol for Achieving Higher Data Rate and Availability

Abstract

By using aggregation of more than one physical interface enables aggregated links to work at the same time for enhancement of bandwidth and data speed beyond capability of single link with additional feature of resilience. However, inappropriate schemes may cause undesirable network behavior and thus requires high efficiency and reliability in its implementation. A new link bundling transport layer protocol is presented which ensures efficient and reliable trunking of multiple wired or wireless network interfaces resulting in escalation of data rate. The proposed scheme is found efficient, reliable and independent of available paths by implementing the Luby transform (LT) codes. The LT codes do not require any interface characteristics management prior to transfer of data which helps in aggregation of interfaces having different characteristics in less time. Also, the data flows seamlessly even if one of the link experiences fluctuation or complete shutdown. The proposed protocol requires less processing requirement, minimum connection establishment time and no interface management as compare to any TCP based protocol. Experimental results demonstrate the effectiveness of the approach.
