Abstract: Since explained by Clark in 2005, live migration become an inevitable standard feature of hypervisors. Performance optimization process of live migration is an active area of research due to its significance in data centers. Major criteria to improve performance optimization is to reduce the amount of data transferred while migration. To reduce amount of data transferred in migration we use delta compression method .The algorithm used for the same is LZ4; because of better compression ratio and faster decompression rate. To utilize multiple paths simultaneously we use MPTCP transmission network instead of conventional TCP. From the experiments we evaluated that delta compression with LZ4 method reduce the amount of data transferred effectively and reduce down time and total migration time during live migration. Utilizing sub flow feature of MPTCP allow to use multiple paths to the destination server, further reduce total migration time. So the method discussed here is a two-fold solution for the performance optimization issue of live migration
