Abstract:

An asynchronous distributed cache protocol was designed to solve the issue of packets loss during migration downtime so as to guarantee
 the reliability and ordering of communication between virtual machines. Besides, we designed and implemented a hybrid virtual network architecture based on the overlay virtual network model. Our virtual network model enables the live migration to be completed across LANs. Our experiments show that the hybrid virtual network model and data cache protocol can effectively solve the problem of virtual machine live migration across LANs.

Key words: live migration, asynchronous distributed cache protocol, communication across LANs, virtual network
