Adaptive queue-management

A method comprising, by one or more computing systems:

• storing in a quality-of-service (QoS) -enabled communication system a data structure that has a multi-level hierarchy comprising:
• a physical level comprising one or more physical-level nodes, each of the physical-level nodes corresponding to a physical interface for transmitting a bandwidth-limited traffic (BLT) stream of packets;
• a logical level comprising one or more logical-level nodes, each of the logical-level nodes comprising a bandwidth-limitation parameter;
• and
• a class level comprising one or more class-level nodes, each of the class-level nodes corresponding to a service provided by the QoS-enabled communication system;
• receiving a first request for M number of services provided by the QoS-enabled communication system;
• and
• in response to the first request, modifying an allocation of the logical-level nodes by mapping M class-level nodes to a first one of the logical-level nodes according to a first mapping mode of the data structure.

One or more computer-readable non-transitory storage media embodying software this is operable when executed by one or more computer systems to:

• store in a quality-of-service (QoS) -enabled communication system a data structure that has a multi-level hierarchy comprising:
• a physical level comprising one or more physical-level nodes, each of the physical-level nodes corresponding to a physical interface for transmitting a bandwidth-limited traffic (BLT) stream of packets;
• a logical level comprising one or more logical-level nodes, each of the logical-level nodes comprising a bandwidth-limitation parameter;
• and
• a class level comprising one or more class-level nodes, each of the class-level nodes corresponding to a service provided by the QoS-enabled communication system;
• receive a first request for M number of services provided by the QoS-enabled communication system;
• and
• in response to the first request, modify an allocation of the logical-level nodes by mapping M class-level nodes to a first one of the logical-level nodes according to a first mapping mode of the data structure.

An apparatus comprising:

• one or more communication interfaces;
• one or more memory devices containing one or more instructions for execution by one or more processing devices;
• and
• the processing devices, operable when executing the instructions to:
• store in a quality-of-service (QoS) -enabled communication system a data structure that has a multi-level hierarchy comprising:
• a physical level comprising one or more physical-level nodes, each of the physical-level nodes corresponding to a physical interface for transmitting a bandwidth-limited traffic (BLT) stream of packets;
• a logical level comprising one or more logical-level nodes, each of the logical-level nodes comprising a bandwidth-limitation parameter;
• and
• a class level comprising one or more class-level nodes, each of the class-level nodes corresponding to a service provided by the QoS-enabled communication system;
• receive a first request for M number of services provided by the QoS-enabled communication system;
• and
• in response to the first request, modify an allocation of the logical-level nodes by mapping M class-level nodes to a first one of the logical-level nodes according to a first mapping mode of the data structure.
