Abstract
In a network architecture, selective grooming is performed. In selective grooming, a low traffic node is coupled (a) directly to an other low traffic node via a high capacity trunk, and (b) to a high traffic node via a high capacity trunk such that only a portion of the client signals destined for the other low traffic node are groomed into the high capacity trunk to the high traffic node.
Claims18
A node for grooming low capacity client signals into a high capacity signal, comprising:
- an interface to a high capacity trunk for coupling to a type one node;
- and
- an interface to a high capacity trunk for coupling to a type two node;
- wherein only a portion of those low capacity client signals destined for the type one node are groomed into the high capacity trunk to the type two node.
Apparatus for performing selective grooming of client signals, the apparatus comprising:
- a node coupled (a) directly to a first node via a high capacity trunk, and (b) to a second node via a high capacity trunk such that only a portion of the client signals destined for the first node are groomed into the high capacity trunk to the second node.
A method for use in performing selective grooming, the method comprising the steps of:
- determining an aggregate amount of traffic between two landing sites;
- and
- if the determined aggregate amount of traffic is greater than a predetermined portion of a high capacity trunk, provisioning a trunk for directly connecting the two landing sites.
A method for use in node, the method comprising the steps of:
- receiving low capacity client signals;
- selectively grooming a portion of the received low capacity client signals into a high capacity trunk for transmission to a first type of node;
- and
- transmitting others of the low capacity client signals over an other high capacity trunk directly coupled to a second type of node
