65. A method of allocating resources in a plurality of transmission media, in which method data is associated with different classes of traffic, the different classes of traffic being associated with different priority levels, wherein resources are selectively reserved on the transmission media for traffic classes in accordance with the associated priority level;
- the method comprising;
allocating a predetermined set of traffic to ones of the media; and responsive to a failure of a transmission medium, re-allocating the predetermined traffic allocated to that transmission medium to one or more other transmission media in combination with the predetermined traffic allocated to said one or more other transmission media; wherein in the event that the one or more other transmission media do not have the capacity to take the existing traffic in addition to traffic from the failed transmission medium, the combined traffic thus associated with any transmission medium is allocated thereto in dependence on the priority associated with respective traffic classes. - View Dependent Claims (66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 81, 82, 84, 85, 86, 87, 88, 89, 90)
- the method comprising;
-
77. A method of allocating resources on transmission media having respective capacities, at least some data being associated with a traffic class having an associated priority level, the method comprising allocating data to at least one transmission medium, wherein responsive to failure of a transmission medium, traffic allocated to the failed transmission medium is allocated to at least one further transmission medium;
- wherein in the event that the at least one further transmission medium does not have the capacity to take existing traffic in addition to traffic from the failed transmission medium, the combined traffic is allocated thereto in accordance with a priority associated with the traffic.

83. A method of allocating traffic in which traffic is transmitted on at least two transmission media, traffic being associated with a traffic class, each traffic class being associated with a priority, and each media having a respective resource for traffic, wherein responsive to a failure on one transmission medium, the combined traffic for the at least two transmission media is allocated to the remaining at least one transmission medium in dependence on the priority of the traffic class, wherein once the resource of the at least one remaining transmission medium has been used up, traffic associated with any remaining traffic is allocated to the at least one remaining transmission medium on a best-effort basis.
-
91. A resource allocator for a plurality of transmission media, in which data is associated with different classes of traffic, the different classes of traffic being associated with different priority levels, wherein the resource allocator is adapted to selectively reserve resources on the transmission media for traffic classes in accordance with associated priority levels;
- there further being provided a rule allocator to determine the allocation of traffic to one or more of the transmission media, and a detector for detecting the status of the transmission media;
wherein responsive to detection of failure of a transmission media;
the resource allocator is adapted to allocate traffic allocated to the failed transmission media to one or more of the other transmission media; andthe resource allocator being adapted such that traffic allocated to the failed transmission media is allocated to one or more of the other transmission media in dependence on the traffic class in the event that the one or more other transmission media do not have the capacity to take the existing traffic in addition to traffic from the failed transmission medium. - View Dependent Claims (92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 109, 110, 112, 113, 114, 115, 116, 117, 118)
- there further being provided a rule allocator to determine the allocation of traffic to one or more of the transmission media, and a detector for detecting the status of the transmission media;
-
105. A resource allocator for allocating resources on transmission media having respective capacities, at least some data being associated with a traffic class having an associated priority level, the resource allocator including:
- a data allocator for allocating data to at least one transmission medium, and a detector for detecting failure of a transmission medium;
wherein responsive to failure of a transmission medium, the data allocator is adapted such that traffic allocated to the failed transmission medium is allocated to at least one further transmission medium, the traffic being allocated thereto in accordance with a priority associated with the traffic in the event that the at least one further transmission medium does not have the capacity to take the existing traffic in addition to traffic from the failed transmission medium. - View Dependent Claims (106, 107, 108)
- a data allocator for allocating data to at least one transmission medium, and a detector for detecting failure of a transmission medium;
-
111. A resource allocator for allocating traffic in which traffic is transmitted on at least two transmission media, traffic being associated with a traffic class, each traffic class being associated with a priority, and each media having a respective resource for traffic, the resource allocator being adapted such that responsive to a failure on one transmission medium, the combined traffic for the at least two transmission media is allocated to the remaining at least one transmission medium in dependence on the priority of the traffic class, wherein once the resource of the at least one remaining transmission medium has been used up, traffic associated with any remaining traffic is allocated to the at least one remaining transmission medium on a best-effort basis.
