Improvement And Implementation Of Virtual Network Identification Mechanism For OpenVirtex Network Virtualization Platform

Network virtualization is one of the most important technologies in the future. Through the network virtualization technology, network service providers can create multiple virtual networks on the underlying physical network to provide users with a variety of customizable services. Through the virtual network traffic identification mechanism to physical and cyber source is divided into a plurality of virtual network and the physical network flow is divided into a plurality of mutually disjoint sets are distributed to different virtual network processing, to maintain the independence of each virtual network control logic and flow isolation.Although the academic and engineering circles have made some achievements in the research of the virtual network identification mechanism, there are still many areas to be improved and improved in the virtual network identification mechanism. The existing virtualization platform there is a common problem, they are all based on the packet in the common field or field combination to identify sections, which requires mandatory for users to opt out of the related field, and the field test for different groups of users requirements, perhaps the hope to control the field is different, it is you need to be able to provide a virtual network identification mechanism is flexible, also makes this problem facing lots of challenge.Aiming at this problem, improvement and Optimization on the recognition mechanism of OpenVirtex virtual network, with a more holistic and global perspective as a starting point, considering various constraints in real application environment and useful information, through dynamic virtual network mapping algorithm will be mapped to the physical network,virtual network with arbitrary topology the. Support a variety of virtual network traffic identification tags, the formation of a more perfect mechanism, optimize the overall situation is stronger, and can be used in engineering practice virtual network identification mechanism. This more flexible virtual network identification mechanism can meet the needs of the vast majority of test users, greatly improving the availability and scalability of the network virtualization platform.
