PACK: Prediction-Based Cloud Bandwidth and Cost Reduction System

Abstract In this paper, we present 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. PACK’s main advantage is 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. This makes PACK very suitable for pervasive computation environments that combine client mobility and server migration to maintain cloud elas ticity.

Abstract con… 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. We present a fully functional PACK implementation, transparent to all TCP-based applications and network devices. Finally, we analyze PACK benefits for cloud users, using traffic traces from various sources.

Existing System CLOUD computing offers its customers an economical and convenient pay-as-you-go service model, known also as usage-based pricing [2]. Cloud customers1 pay only for the actual use of computing resources, storage, and band¬width, according to their changing needs, utilizing the cloud’s scalable and elastic computational capabilities. In particular, data transfer costs (i.e., bandwidth) is an important issue when trying to minimize costs [2]. Consequently, cloud customers, applying a judicious use of the cloud’s resources, are motivated to use various traffic reduction techniques, in particular traffic redundancy elimination (TRE), for reducing bandwidth costs.

CONCLUSION Cloud computing is expected to trigger high demand for TRE solutions as the amount of data exchanged between the cloud and its users is expected to dramatically increase. The cloud en¬vironment redefines the TRE system requirements, making pro¬prietary middle-box solutions inadequate. Consequently, there is a rising need for a TRE solution that reduces the cloud’s op¬erational cost while accounting for application latencies, user mobility, and cloud elasticity.
