Process of Traffic Policing In traffic policing, the Committed Access Rate (CAR) is used to control traffic. Packets are first classified according to pre-defined matching rules. Packets that conform to the specified rate limit are forwarded directly, whereas packets that exceed the specified rate limit are dropped or have their priorities re-marked before being retransmitted. …

The inter-AS seamless MPLS+HVPN networking obtains the collective advantages of the inter-AS seamless MPLS network and HVPN. Networking Requirements In Figure 1, the access and aggregation layers …
Continue reading Example for Configuring Inter-AS Seamless MPLS+HVPNWhen the access and aggregation layers belong to one AS, and the core layer belongs to another AS, inter-AS seamless MPLS can be configured to implement the service connectivity between a NodeB and an MME or SGW. Networking Requirements In Figure 1, the access and aggregation layers belong to one AS, and the core layer belongs …
Continue reading Example for Configuring Inter-AS Seamless MPLSWhen the access, aggregation, and core layers belong to the same AS, intra-AS seamless MPLS can be configured to implement the service connectivity between NodeBs and an MME or SGW. Networking Requirements In Figure 1, the access, aggregation, and core layers belong to the same AS. NodeBs need to communicate with an MME or SGW over …
Continue reading Example for Configuring Intra-AS Seamless MPLSSeamless MPLS network reliability can be improved using a variety of functions. If a network fault occurs, devices with reliability functions enabled immediately detect the fault and switch traffic from active links to standby links. The following examples demonstrate the reliability functions used on an inter-AS seamless MPLS network. A fault occurs on a link …
