EXISTING SYSTEM

PROPOSED SYSTEM

EXISTING CONCEPT:-

In the Existing system are OFG has the advantage of being a sequential decoder and it is able to incrementally consume and decode the received coded fragments. This is achieved by maintaining k decoding matrix that represents the set of collected linearly independent equations.

OFG can be used to incrementally filter the coded fragments to guarantee. This is achieved by imposing an additional constraint on the decidability of the fragments: ideally we want every coded fragment to be innovative

PROPOSED CONCEPT:-

In the proposed system are users and applications the access to persistent blocks storage devices (virtual disks) that can be directly accessed and used as if they were raw physical disks.

In this paper we investigate how a family of codes, known as Luby Transform codes can be used as the enabling technology for BLCS systems able to solve the problems mentioned above. In coding-based storage system, the data units are first split into k equal size information fragments.

EXISTING ALGORITHM:-

OFG Algorithm.

PROPOSED METHODS:-

Efficient algorithm.

ALGORITHM DEFNITION:-

This goal is achieved exploiting the mechanism used by OFG to build the decoding matrix without any additional modification; in particular, the jth equation is marked as innovative if it can be used to fill a new row of the OFG decoding matrix

TECHNIQUE METHODS:-

The proposed process eliminates failure while slightly improving also in terms of average decoding overhead.

ENIGMA employs caching to tolerate network latency and therefore the encoding of a sector is required only when it must be expunged from the cache.

DRAWBACKS:-

Not so efficient if there is heavy interaction between branches.

Data should be carefully maintained.

ADVANTAGES:-

This techniques is very efficient.

We can store the data normally and efficiently..
