Research Of Evolution Strategies For MAN Facing The Entire Business Operation

According to the demand of the entire business operation,considerding the exiting network of the Guangdong Mobile,expored the methods of carrying the entire business and come to the network construction palns,by the research of new technologies for MAN.Huge investments,complex troubles are the problems of MAN construction which always persecutes the network operators。The new technologies for the MAN are emergeing out of the old,because of the focus of the network operators and the huge business opportunities for the manufacturers.Different existing networks,different demands for the technology and enquipment,which bring on the development direction for the MAN is multifarious.But using the MAN carrying the multi-service and minimizing the OPEX are the mutual demand of the network operators.With the development of the domestic broadband-access,the MAN is becoming the bottleneck which network operator fast reaction for the market and carrying the multi-service,so a new upsurge of MAN construction is setting off in China.Firstly, this article analysed the key technologies for the MAN including cluster,PPPoE and DHCP,accurate identification for consumers and the realization of QinQ,L2/L3 VPN and the QoS guarantee of VPN.Be aimed at these service which including a family Internet-access,VoIP-access,a enterprise VPN-access,IPTV-access and researched the carrying methods,offered the thereunder of the network construction plan.Secondly,according to the development customers and the existing network of Guangdong Mobile, formulated the target architecture of the big MAN,bring up the demands of functions and capabilities under this target architecture. Analyzed the service flow direction,the impacts of the network maintenance and manegment,matching of the existing resources under this target architecture. Estimated the amounts of investment under this target architecture.Finally, according to the target architecture shaped the specific scheme of network construction.Including the principle of zoning,the node setting,the scale of consumer forecasting,the intercommunity of network,the contrast of investment. The author hopes some parts of this paper could afford a reference for the research of Evolution Strategies for MAN.
