and for a large-scale backbone network, it is an excellent TE solution for its great extensibility and ease
of implementation.
MPLS is better than IGPs in implementing traffic engineering for the following reasons:
• MPLS supports explicit label switched path (LSP) routing.
• LSP routing is easy to manage and maintain compared with traditional packet-by-packet IP
forwarding.
• Constraint-based Routed Label Distribution Protocol (CR-LDP) is suitable for implementing a variety
of traffic engineering policies.
• MPLS TE uses less system resources compared with other traffic engineering implementations.
MPLS TE Management
The MPLS TE Management component is a simple, efficient, visual management tool. It helps you
manage network operations and assign network resources reasonably. The MPLS TE Management
provides these functions: MPLS TE topology, resource management, advanced RSVP-TE features, MPLS TE
tunnel Management, explicit path management, protection management, and traffic access
management.
• TE Topology—This function provides a graphical view of all MPLS TE tunnel information, visually
reflecting the current network performance. You can use the information to optimize the network
performance.
• Resource Management
{
Device Management—This function allows you to import and synchronize MPLS TE devices.
Devices to be imported must support MPLS TE. The devices support manual synchronization and
automatic synchronization.
{
Interface Management—This function allows you to configure interfaces of devices to
implement MPLS TE.
• RSVP TE Advanced Features
{
Device Features—This function allows you to perform device RSVP TE configurations on MPLS TE
devices.
{
Interface Features—This function allows you to perform interface RSVP TE configurations on
MPLS TE devices.
• MPLS TE Tunnel Management—This function helps you establish MPLS TE tunnels, including static
and dynamic tunnels. This allows traffic to bypass congested nodes to achieve appropriate load
distribution.
• Explicit Path Management—This function allows you to configure explicit paths for dynamic tunnels.
• Protection Management—This function helps you with dynamic tunnel protection, including CR-LSP
backup and FRR, so that traffic is switched to another path when the current link encounters a
problem or congestion occurs on a network node.
