A Novel Approach for Cloud Bandwidth Reduction and Cost Reduction Using PACK

Rajalakshmi.N | Aneel Narayanpur


Abstract: The PACK (Predictive ACKs), a novel end-to-end traffic redundancy elimination (TRE) system, designed for cloud computing customers. Cloud-based TRE needs to apply a judicious use of cloud resources so that the bandwidth cost reduction combined with the additional cost of TRE computation and storage would be optimized. PACKs main advantages its capability of offloading the cloud-server TRE effort to end clients, thus minimizing the processing costs induced by the TRE algorithm. Unlike previous solutions, PACK does not require the server to continuously maintain clients status. The PACK is suitable for pervasive computation environments that combine client mobility and server migration to maintain cloud elasticity. PACK is based on a novel TRE technique, which allows the client to use newly received chunks to identify previously received chunk chains, which in turn can be used as reliable predictors to future transmitted chunks. And a fully functional PACK implementation, transparent to all TCP-based applications and network devices.
