CCIT MPLS-VPN IP Private Network

 CCIT MPLS-VPN IP Private Network

The MPLS-VPN is built on CUnet or AS9929 network. It mainly uses Multi-Protocol Label Switching (MPLS) technology to build an internal private network to realize internal data, voice, and image between multiple cross-border branches. A service for business communication.

Technical application note:

MPLS VPN is a network technology for multi-protocol label switching and transporting packets on Layer 2 and Layer 3 media. The switching path can be point-to-point, multi-to-one, one-to-many, and many-to-many. It provides unique traffic class service (CoS) and quality of service (QoS). It can be set to prioritize unlatched, real-time traffic levels, assigning the right bandwidth for each application, and no longer freely competing for bandwidth. It supports high bandwidth utilization and low line rent.

The target customers are headquarters-type enterprises (IT companies, trade industry, news organizations, manufacturing, etc.), foreign-funded enterprises and offices.

The main application methods are:

1. Multi-branch enterprise interconnection (Intranet business): These companies have multiple branches in different locations. Most of them are enterprises with cross-domain voice and simple data requirements, and they do not have the ability to build private line networks across domains.

2. Enterprise and related partner interconnection (Extranet business): Some companies have frequent contacts with upstream and downstream business partners (suppliers or group customers), or have a large number of B2B business needs. MPLS-VPN provides a secure connection between business partners and also provides B2B's business model with greater security and reliability. Educational research institutions, news organizations, or group organizations can also use it to establish connections. 

 

Features： 

1. Quickly connect to the world with SDH, ATM and FR

2. Low latency, high reliability, and SLA protocol

3. COS and QOS can effectively guarantee the utilization of data

4. Flexible networking, strong scalability, high security

5. The price of multi-point networking is low

 

Ø Flexible networking and simple maintenance

The client router is only connected to the network operator's local node router and not directly to other nodes of the customer network.

 The MPLS VPN routing information is stored on the router of the carrier and managed by the operator. The customer does not need to perform special maintenance and management.

Ø Maintain customer's original network planning

The MPLS-VPN service has no special requirements for the client device, and the general router is applicable. Therefore, the customer can continue to use the original device to effectively protect the user's investment.

 The MPLS-VPN service supports the use of private addresses. If the customer has an existing LAN, there is no need to change the address plan.

 

Ø Safe and reliable

Each customer routing table is independent, and transparent packet transmission is implemented according to MPLS label switching, and has a similar security level as traditional VPNs such as ATM and FR.

Customer's own data encryption guarantees data security.

 It is carried on the CU net (IP network), and automatically returns the traffic to the fault point when the fault occurs, which has high reliability.

 

Ø Multiple business integration

Traditional technology can only be implemented on three different networks, and users need to rent three different telecommunication services;

 Three communication applications are implemented on Netcom's MPLS-VPN on the same network, that is, "three networks in one."

 

Ø High-quality service guarantee

CU net relies on the powerful QOS capabilities provided by routers to provide critical communication quality by supporting different service levels and supporting different applications.

The MPLS-VPN core layer only performs Layer 2 switching of IP data packets according to MPLS labels, speeds up packet forwarding, reduces delay and jitter, increases network throughput, and greatly improves network quality assurance.

Different levels correspond to different prices to achieve differentiated services.
