Network resource reallocation
First Claim
1. A method comprising:
- ascertaining whether resources of an apparatus include total available bandwidth sufficient to carry a peak expected bandwidth for a data type which is the subject of a received request for a connection, wherein the apparatus includes one or more communication ports at which one of more termination points are established and wherein the one or more termination points terminate a requested connection;
in the event that the total available bandwidth is sufficient to carry the peak expected bandwidth for the data type which is the subject of the received request for a connection, but the arrangement of said one or more termination points is such that the total available bandwidth is too fragmented to be used by the requested connection, determining how to best reallocate the bandwidth among the one or more termination points to allow the requested connection to be established; and
without breaking one or more connections to which said one or more termination points relate, rearranging said one or more termination points in accordance with a result of the determining of how to best reallocate the bandwidth among the one or more termination points to allow the requested connection to be established.

Abstract
A method of assigning resources within a network element within which a traffic termination point or AAL2 termination point has been established is described. The network element accepts a connection request, and it is then ascertained whether available resources have sufficient capacity to establish the requested connection. In the event that there is sufficient capacity, it is ascertained whether the termination points defined in relation to the available resources fragments the resources such that the connection cannot be established. If the resources are so fragmented, then one or more of the termination points are reallocated, without breaking the connection to which they relate, thereby defragmenting the resources sufficiently that the requested connection can be established.

8. A apparatus comprising:
-
a processor; and memory operatively coupled to the processor and including computer program code that, when executed, cause the apparatus to; ascertain whether resources of a node include total available bandwidth sufficient to carry a peak expected bandwidth for a data type which is the subject of a received request for a connection, wherein the node includes one or more communication ports at which one of more termination points are established and wherein the one or more termination points terminate a requested connection; in the event that the total available bandwidth is sufficient to carry the peak expected bandwidth for the data type which is the subject of the received request for a connection, but the arrangement of said one or more termination points is such that the total available bandwidth is too fragmented to be used by the requested connection, determining how to best reallocate the bandwidth among the one or more termination points to allow the requested connection to be established; and without breaking one or more connections to which said one or more termination points relate, rearranging said one or more termination points in accordance with a result of the determining of how to best reallocate the bandwidth among the one or more termination points to allow the requested connection to be established. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A apparatus comprising:
-
means for ascertaining whether resources of a node include total available bandwidth sufficient to carry a peak expected bandwidth for a data type which is the subject of a received request for a connection, wherein the node includes one or more communication ports at which one of more termination points are established and wherein the one or more termination points terminate a requested connection; means for determining how best to reallocate the bandwidth among the one or more termination points to allow the requested connection to be established, in the event that the total available bandwidth is sufficient to carry the peak expected bandwidth for the data type which is the subject of the received request for a connection, but the arrangement of said one or more termination points is such that the total available bandwidth is too fragmented to be used by the requested connection; and mean for rearranging, without breaking one or more connections to which said one or more termination points relate, said one or more termination points in accordance with a result of the determining of how to best reallocate the bandwidth among the one or more termination points to allow the requested connection to be established. - View Dependent Claims (16, 17, 18, 19, 20, 21)
