Research On The Deployment Of VBRAS Based On NFV Architecture In Metropolitan Area Network

In recent years,China's government has launched the "Internet plus" and "broadband Internet China" and other major strategic initiatives,the Internet has gradually become the basic national strategy in the new situation of the facilities,the development of Internet,network data communication industry is facing many new challenges,network openness and innovation has become the main trend one of the.The current mainstream telecom operators data network is difficult to quickly respond to the requirements of the future development of the Internet business,data network upgrade and network architecture has become the common goal of major telecom operators.At the same time,in the face of sustained and rapid growth of Internet traffic and the continuous introduction of the Internet business,the traditional BRAS in terms of equipment utilization,backup mechanism,deployment cycle,etc.are difficult to deal with.In this thesis,the combination of theory and practice,focusing on the following aspects:(1)in the new Internet business development environment,in-depth analysis of the current mainstream of the operation of the mall in the field of traditional BRAS hardware,software,backup and other aspects of the problem.(2)through detailed analysis and comparison of current key technologies including SDN,SDN/NFV,NFV,Overlay,quasi selection advantage NFV architecture based on VBRAS technology is more obvious,more mature technology,to solve the various problems existing in traditional BRAS.(3)the VBRAS test environment based on NFV architecture is built in the actual operation mall network,and the function and performance of the H3 C VBRAS are verified.(4)according to the test results before the festival,with the difference compared with the traditional BRAS and VBRAS,analysis of NFV architecture VBRAS deployment scenarios based on the proposed architecture based on NFV VBRAS in the current mainstream network environment deployment principle and application scenarios for future mainstream telecom operators in the internal department of city area network to provide reference and VBRAS reference.
