Packet-Transmission control method and packet-transmission control apparatus
First Claim
1. A packet-transmission control method for controlling transmission of packets, said method comprising:
- a judgment step of forming a judgment as to whether or not the number of queue buffers that can be used for VC merging is smaller than the number of VCs to be merged in processing to merge a plurality of virtual connections into 1 virtual connection; and
a merging step of merging virtual connections by giving a high priority to one with a large number of virtual connections to be merged in accordance with an outcome of said judgment formed at said judgment step.

Abstract
The invention relates to a packet-transmission control method for controlling transmission of packets, the method comprising, a judgment step of forming a judgment as to whether or not the number of queue buffers that can be used for VC merging is smaller than the number of VCs to be merged in processing to merge a plurality of virtual connections into one virtual connection, and a merging step of merging virtual connections by giving a high priority to those virtual connections in a list having a large number of virtual connections to be merged in accordance with an outcome of the judgment formed at the judgment step, and relates to a packet-transmission control apparatus for controlling transmission of packets.

5. A method for merging virtual connections, the method comprising:
-
determining a maximum number of virtual connections that can be merged;
determining a priority for each set of virtual connections to be merged; and
merging a set of virtual connections having the highest priority, if the set is smaller than the maximum number. - View Dependent Claims (8)

6. A packet-transmission control method for controlling transmission of packets, the method comprising:
-
determining whether the number of queue buffers available for merging a set of virtual connections (VCs) is sufficient to support a merging operation for merging the set of virtual connections into a single virtual connection; and
merging the virtual connections, if the number of queue buffers is sufficient, by giving priority to a set of virtual connections having a highest priority designation.
