Applications

H3C AR 28 in Enterprise Inter-connect Network

 

 

Main point of the this topology:

  1. AR28 series routers can be connected to the DDN, Frame Relay or X.25 through Syn/Asyn serial or CE1 modules, to PSTN through Asyn serial, to ISDN through ISDN BRI or PRI interface modules;
  2. The main lines and backup lines can be switched automatically by routers. The back-up can be dial-up backup or routing backup;  

H3C AR 28 in Integrated Terminal Solution for Banks

 

Regional banks can use the terminal server services and SNA function of AR 28 series routers to realize the coexistence of the SNA network and TCP/IP network, so as to provide new services based on IP and finally transit everything in IP network without changing the original system.

Benefits:

  1. Abundant finance features and access types;
  2. Backup technology;
  3. Smoothly evolve from SNA to IP network;
  4. Protect user’s investments.

 

H3C AR 28 in Enterprise IAD (Integrated Access Device) Solution

 

 

AR28 series routers can provide perfect IAD solutions for the SMB and small-to-middle branches;

1.       Support FXS modules, which supports the access to common analog telephone and fax;

2.       Support FXO or E&M modules, which supports the access to telephone exchange (PBX);

3.       Support E1 voice interface module, which provide high-density digital voice for the enterprise;

4.       Support 8/16-port LAN modules, offer small-to-middle-size businesses and enterprise branch office customers the option to integrate switching and routing in one device  

H3C AR 28 in MPLS VPN Solution

 

 

MPLS is the latest achievement on integrated routing/switching solution. It integrates the flexibility of IP routing technology and the simplicity of L2 switching. In addition, it has an outstanding advantage on VPN construction. A MPLS network can conveniently implement the IP-based VPN services to satisfy VPN scalability and manageability. Security measures can be taken on the MPLS VPN to isolate the VPNs. MPLS network also provides powerful QoS mechanism to guarantee the quality of VPN services such as bandwidth, transmission, and delay.

 AR28 series routers, serving as a Provider Edge (PE) router, is directly connected with the Customer Edge (CE) router to perform all the VPN-related functionalities. It exchanges routing information with other PEs through IBGP. A PE can be connected with more than one CE. 

H3C AR 28 in Traditional VPN and MPLS VPN integrated Solution

 

 

MPLS VPN is used for the enterprise network resource logical division and security isolation, often work on the core layer or convergence layer of the network.

 L2TP or GRE VPN is used for the access of the remote branches or mobile users, often work with IPSec on the access layer of the network.

 AR Routers can combine traditional VPN and MPLS VPN to present end-to-end solution for the customer.
