Research On Multi-service Transport Network Of Chang Qing Oilfield

In recent years, with the development of telecom technology and diversified services，video, high rate data services and Applications are increasingly rich. In addition toordinary Internet demand, interactive TV, video phone, property management, home securitysystem are more urgent to consumer. Triple play, which the country is carrying on, isoptimizing resources, and providing network based for multi-service transport network。Inorder to meet the user’s demand，this article is researching the multi-service transport networkof Changqing oilfield and its related technology。In order to meet the diverse needs of user in the network to solve the original problem ofcomputer network load and network planning technology in the multi service, This task willstudy the broadband authentication technology, multicast technology, QinQ technology andP2P technology, and application of this technology to solve the multi service network capacityof Changqing oil field.This article take the broadband authentication mode corresponding to different users inthe network, using QinQ technology, multicast technology, IPTV service and other servicesshare the same IP logical channel, access the service through independent VLAN. Multiservice benefits by dividing the logic plane, so that the network with end-to-end QoSguarantee, through reasonable planning, can meet the requirements of multi serviceQoS. Safety isolation to achieve a variety of business, avoid mutual interference, fullyguarantee the security of the business.
