This color is then used in the core to identify the class to which the packet belongs. Cisco FRR utilizes MPLS label stacking with RSVP signaling to create a backup tunnel around the link or node that needs to be protected. On detection of signal loss of signal from the link, the MPLS FRR application in Cisco IOS software starts forwarding the traffic onto the backup tunnel transparent to end users or applications in 50 ms or less. An MPLS TE feature, called Cisco AutoBandwidth allocator, to ease constant network monitoring and provisioning. The AutoBandwidth feature constantly tracks average use of MPLS TE Tunnel and can resize TE tunnel bandwidth to suit the traffic flow.
Service providers can efficiently utilize available network bandwidth and maximize profits.
The average monitoring duration is configurable, thereby providing better control of network resources. By using Cisco's technology, MPLS guaranteed bandwidth services can be used to construct virtual leased lines for IP traffic, an alternative first available with Cisco IOS software. Increasing utilization of bandwidth by load balancing traffic on alternate traffic engineered paths. Simplifying network manageability and reducing costs with the Cisco AutoBandwidth allocator to take advantage of available tunnel bandwidth while still providing guarantees for high priority traffic. Preventing theft of service with policing.
