8CHAPTER 1: INTRODUCING THE ROUTER 6000 FAMILY

which, implement connection between medium-and-small-sized enterprise networks and ATM networks.

MPLS Multiprotocol Label Switching (MPLS) is a combination of IP and ATM technologies. MPLS replaces the IP header with a short and length-fixed label as traffic identifier. This information is used by the router to make forwarding decisions. This provides faster forwarding speed while getting support from IP routed protocols and control protocols. This meets the requirements that various new applications put on the network. MPLS VPN is a Virtual Private Network technology that implements the interconnection of private networks via Label Switched Paths (LSPs). As a LSP is a tunnel across the public network on its own, MPLS has an intrinsic advantage in terms of VPN implementation. 6000 Routers usually act as Label Edge Routers (LERs) to connect to an MPLS domain with non-MPLS domain or connect to MPLS domains of different service providers.

Support for NAT. Besides some basic functions, the NAT available for 6000 can limit concurrent connections to a single user, and thus alleviate the negative impact caused by malicious resources without compromising the normal network applications. NAT of 6000 also provides the ALG (Application Layer Gateway) function to FTP and ICMP.

Support the authentication protocols such as PAP, CHAP, and data RADIUS

Implement packet filter and stateful firewall for preventing the intrusion from an external network.

Support VPN (including GRE, L2TP, and MPLS) and provide IPSec, and IKE. This ensures the security of the private networks in an Internet environment.

Support the Backup Center and Virtual Router Redundancy Protocol (VRRP) technologies. This enhances the robustness and reliability of the network by providing a backup scheme in case of communication line or device failures. So far, backup center supports backup load sharing.

Support hot swap of fans, interface cards, and power module to ensure high reliability.

Online software You can upgrade the application programs and Boot ROM programs, and add new upgrading features and functions on line as needed.

You can monitor the FIC running state by observing the LEDs on FIC panels.

You can use in-service system test, or out-of-service system test. In addition, loopback test and hardware key module self-test, are allowed.
