forwarding decision. It thus provides faster forwarding speed, gets support from IP routed
protocols and control protocols, and accommodates to emerging applications. MPLS VPN
is a VPN technology that uses label switched paths (LSPs) to interconnect private
networks. As a LSP is virtually a tunnel across the public network, MPLS has an intrinsic
advantage in terms of VPN implementation. The 3Com 6000 Routers usually act as label
edge routers (LERs) to connect an MPLS domain with a non-MPLS domain or connect
MPLS domains of different service providers, implementing service classification, label
distribution, encapsulation, and multi-label peel-off.
V. Data security and reliability
The following are the data security and reliability features that the Router 6000 supports:
z NAT. Besides some basic functions, NAT can limit concurrent connections to a
single user, and thus alleviate negative impacts caused by malicious resource
occupation without affecting the normal network applications. In addition, NAT of
the Router 6000 also provides the application layer gateway (ALG) function
specific to FTP and ICMP.
z Authentication protocols such as PAP, CHAP, data RADIUS, and VoIP RADIUS.
z Packet filter and firewall, which fend off external attacks.
z VPN (including GRE, L2TP, and MPLS) and the technologies of IPSec and IKE.
They can ensure security of private networks in an Internet environment.
z Backup center and virtual router redundancy protocol (VRRP). By providing a
backup scheme in case of communication line or device failures, they enhance
robustness and reliability of networks. Backup center also supports backup load
sharing.
z Hot swappable fans, interface cards, and PSUs to ensure high reliability.
VI. Online software upgrading
You are allowed to upgrade application and Boot ROM programs, and add new features
and functions on line as needed.
VII. Abundant fault isolation methods
z The monitoring of the states of system configurations, system service channels,
and system resources is available, as well as fault indication via console and
network management host. In addition, logging function is provided for recording
and outputting the abnormal information.
z You are allowed to monitor the FIC running state and make the judgment by
observing the LEDs on FIC panels.
z You are also provided with the functions of in-service system test and
out-of-service system test. In addition, loopback test and hardware key module
self-test are allowed.
