MLFR is a bundling capability allowing users to spray FR frame fragments over multiple T1/E1 links. This allows a dynamic provisioning of additional bandwidth by adding incremental bandwidth between T1/E1 and DS3/E3. A MLFR bundle increases fault tolerance and improves QoS characteristics because one single large frame of low priority cannot block a higher priority frame.
A MLFR supports up to eight (8) member links and a maximum of 128 bundles with up to 336 T1/252 E1 members links can be configured per MDA. NxDS0 circuits or higher speed circuits are not supported.
The MLFR implementation supports FRF.16.1 bundle link integrity protocol to verify serviceability of a member link.
