MPLS VPN builds broadband network for enterprise

What is VPN

VPN (Virtual private network) is a kind of business that uses public network resources to build a private network for customers, it transmits private data on the public Internet and achieves the security level of private network through packet and encrypted transmission of network data.

It has two characteristics. First, virtual. It does not need to set up a special network for the physical connection, the use of public network resources, as long as there is connectivity to the public network of physical resources. Second, dedicated. It has the characteristics of the special network, can realize the reasonable allocation of public resources and dedicated resources.

VPN establishes the private data transmission channel through the public network, can connect the remote branch office, the business partner, the mobile office personnel and so on, reduces the enterprise remote access expense burden, provides the secure End-to-end data communication.

Because of the many features of the public and private networks, VPN can make the public network reliable performance, expansibility, rich function and private network security, flexible, efficient combination, not only can reduce the user network equipment investment and line, reduce the user's monthly communication expenses, At the same time, the use and maintenance of the network become simple, easy to manage and expand, reduce the network operation and management of human and material costs.

Netcom MPLS VPN

MPLS VPN belongs to one of the Ip-vpn. According to Gao Yin, senior manager of CNC Data Product Management Department, IP-VPN adopts network-based solution technology to construct intranet and extranet to meet various flexible business forms. Ip-based VPN can seamlessly interconnect offices or internal networks in different regions, and can further expand external networks, connect business partners, suppliers and key users, thereby strengthening contacts, reducing costs and ensuring better business relationships.

At the same time, Ip-vpn can also provide corporate Internet services, IP telephony, as well as video conferencing, distance teaching, Information bulletin, a variety of application services and network business applications.

Ip-vpn is applicable to all kinds of large and medium-sized enterprises, especially those who need efficient operation, frequent business activities, large data communication, high degree of network dependence, have branches of enterprises and organizations. Like network companies, IT companies, the financial industry, news organizations and so on.

He said: "In the Ip-vpn family, MPLS VPN for users of the demand point is high bandwidth, mainly to meet those who need more than 2M of bandwidth applications." Netcom Broadband backbone network to provide users with large bandwidth transmission of the physical foundation, with high-speed and stable bandwidth and transmission rate, on the basis of the MPLS VPN is an end-to-end, full network of MPLS VPN. ”

Although MPLS technology has been widely publicized and promoted abroad, however, the technology in China is still a new face, there are many questions about the type, quality and price of the services that MPLS VPN can provide, and the security of MPLS technology in the industry, There are also different voices for scalability and the real cost savings that can be achieved.

Gao Yin that, in essence, Netcom MPLS VPN is not only a product, but also a service, it is based on MPLS technology, combined with differentiated services, flow engineering, to provide users with high-quality private network services. It has the following characteristics:

First, high security. First, Netcom MPLS VPN provides full redundancy protection from equipment, route to route, secondly, using MPLS as the channel mechanism to realize transparent message transmission, and the operator core network is invisible, it can reach the same security level as DDN and Fr; Again, users can still use their own network protection measures , such as firewalls, data security encryption, enhance the ability of the network to resist attacks.

Second, the expansion of strong. First, the scalability of the network itself. The VPN built on the Cncnet network can coexist, independent and influence each other, and each VPN user can expand its network freely. Second, business Extensibility. Netcom MPLS VPN will gradually achieve the following services: Internet Access Services (DIA), service Gateway, voice, video conferencing and ERP, CRM vendors to cooperate with the application-oriented services.

Third, flexible control strategy and strong management function. First of all, Netcom MPLS VPN can formulate special control strategy to meet the special requirements of different users, realize value-added services; Secondly, the centralized management of the business configuration and scheduling unified platform.

Four, service level agreements. Provide differentiated services, traffic shaping and service levels to ensure a certain level of communication quality.

Gao Yin introduced, Netcom MPLS VPN can also help users achieve cost savings, this mainly in several aspects. First, the line fee. Netcom MPLS VPN Price is more economical than leased line. Second, equipment costs. The user should only be equipped with CPE equipment and no special access equipment is required. Third, the integration of business. Users can save their daily telephone charges by compounding the devices that provide voice services. Four, management expenses. User-side equipment maintenance is very simple, users do not have to do specialized management maintenance.

He said that in the Netcom MPLS VPN, users only need to be connected to the point of renting the local circuit into China Netcom Ip-vpn network can be, do not need to rent another PVC circuit, which saves users including physical circuits, PVC, equipment, maintenance and other aspects of a large number of costs.

Market positioning

Gao Yin that, because MPLS technology is already very popular abroad, so after China's entry into the WTO, foreign companies entering the mainland will be more willing to use MPLS VPN, but in China because the concept of VPN has just arisen, MPLS technology is also being promoted, for the acceptance of MPLS VPN, Domestic enterprises also have a learning, validation and discussion process.

He said: "With the characteristics of the product itself, MPLS VPN is more suitable for those points more connections, generally can reach dozens of points, but for the traditional low bandwidth applications, users only 2~3 point or point-to-point connection, DDN and Frame relay or have their own advantages." Therefore, MPLS VPN should be based on its own advantages, the development of the corresponding market. ”

Gao Yin said that the Netcom MPLS VPN service will not compete with the low bandwidth access services, and the MPLS VPN also has some cooperation with the Frame Relay service in the enterprise 2M bandwidth application level.

Development and future

For the current situation of the development of Netcom MPLS VPN business. Gao Yin said: "Some Netcom's domestic users, such as Tatsu, Shiseido, such users are already in the process of gradually opening this business." ”

However, Gao Yin also said that domestic users to open MPLS VPN business still has a process problem. He said: "For instance, it is the first to put the Enterprise Office system into MPLS VPN." After the implementation of this step, it began to consider the voice system to join the MPLS VPN, in the implementation of MPLS VPN communication between the branches. After the speech system is built, it will also add other business to its own client. At the same time, China Netcom is also testing its own conference TV system, these applications are to be implemented step-by-step. ”

As the first operator to provide MPLS VPN in China, Netcom also hopes to have extensive cooperation with international operators in this area. Gao Yin Introduction: "Netcom is with the United States, the United Kingdom, Japan's operators to contact, for the future launch of International MPLS VPN business ready." ”
