EXISTING SYSTEM

PROPOSED SYSTEM

EXISTING SYSTEM:

In environments that not combine client mobility and server migration so it should not able to maintain cloud elasticity.

In particular, data transfer costs (i.e., bandwidth) is an important issue when trying to minimize costs. Consequently, cloud customers, applying a judicious use of the cloud’s resources

PROPOSED SYSTEM:

PACK, a receiver-based, cloud-friendly, end-to-end TRE that is based on novel speculative principles that reduce latency and cloud operational cost.

PACK does not require the server to continuously maintain clients’ status, thus enabling cloud elasticity and user mobility while preserving long-term redundancy.

EXISTING TECHNIQUE

Traffic Redundancy Elimination (TRE).

PROPOSED TECHNIQUE

PACK (Predictive Acknowledgement).

TECHNIQUE DEFINITION

TRE solutions are popular at enterprise networks, and involve the deployment of two or more proprietary-protocol, state synchronized middle-boxes at both the intranet entry points of data centers and branch offices, eliminating repetitive traffic between them.

TECHNIQUE DEFINITION

The stream of data received at the PACK receiver is parsed to a sequence of variable-size, content-based signed chunks. The chunks are then compared to the receiver local storage, termed chunk store

DRAWBACKS

It had issues in minimizing the cost using bandwidth calculation.

Cloud consumers were not got correct pay for their usages.

ADVANTAGES

The cloud environment redefines the TRE system requirements, making proprietary middle-box solutions inadequate.

Consequently, there is a rising need for a TRE solution that reduces the cloud’s operational cost while accounting for application latencies, user mobility, and cloud elasticity.
