Huawei certification: VPN optical Ethernet to carry forward

The intelligent ADLE optical network, network traffic distribution becomes more flexible, network operators can provide more types of network services, such as OVPN.

It is understood, a stage of China Netcom were multiple vendor optical Ethernet equipment test based on VPN. In fact, the current major domesticoperators have realized the importance of this system, has embarked on atechnology assessment and actively carry out test.

As the backbone network and wide area network in the city within the scope of the extension, the metropolitan area network connecting the city tens of thousands of users, is the key to providing a new generation of voice service and data service location. Due to the deployment, in the metropolitan area network edge setting and management of a large number of equipment, so theman took most of the operators of the capital budget and the operating budget.

From the analysis of the current China Telecom, China Netcom, China Unicomhas been implemented and applied to the metropolitan area network, because the network using IP routing technology of the third layer, network deployedrouting equipment and complicated structure, the equipment has greatlyincreased the operator's investment cost. This is caused by the data businessinvestment, low income phenomenon. Therefore, how to reduce networkoperation cost is the main problem of the operator attention.

Many in the industry are concluded, the cost for Ethernet is a good method to solve the challenges of metropolitan area network. At present, 98% of the local area network (LAN) is based on Ethernet based. How will the Etherneteconomic, simple, easy to use features applied to operators in metropolitan area networks, each network equipment providers concern.

The use of Ethernet technology in metropolitan area network communication system, combined with the scalability and reliability of optical networktechnology. Some network devices to exchange for MPLS based network,optical Ethernet development can provide VPN services, to help the operators in the construction of metropolitan area network.

Optical Ethernet with the Ethernet simplicity, economy and reliability of opticalequipment and large capacity, provides a specialized for metropolitan area network and wide area network design solutions. Optical Ethernet can use different types of Ethernet transmission, including bare fiber Ethernet(Ethernet over Optical), DWDM Ethernet (Ethernet over DWDM) and resilient packet ring Ethernet (Ethernet over RPR). No matter what type of deployment of transmission network, each component can use simple and economicalEthernet to provide service.

Optical Ethernet with VPN is a second layer of VPN, using Ethernet as a link layer protocol, VPN tunnel is established through the MPLS label switching,transmission of VPN service. Because the VPN service is based on theEthernet environment, it is also called VPE (Virtual Private Ethernet). Using Ethernet "any to any" dynamic structure, ASPB VPN users can support a greater number in the metropolitan area network.
