View Patent ↗A technique enabling diverse communication quality control for a communication service is provided. A communication apparatus according to the present invention is a communication apparatus that performs communication over a communication path set up in a network, including: a first means for identifying the communication path corresponding to a packet; and a second means for adding quality information to the packet, wherein the quality information is selected from among a plurality of pieces of quality information associated with a quality class of the identified communication path.
1. A communication apparatus, comprising:
a memory storing a plurality of quality identifiers; and
a processor configured to execute program instructions to:
receive a packet;
identify, based on the received packet, a first path attribute and a second path attribute corresponding to a communication path of the received packet;
select, based on the first path attribute and the second path attribute, one of the plurality of quality identifiers;
add the selected quality identifier to the received packet; and
forward the received packet including the selected quality identifier.
2. The communication apparatus according to claim 1 , wherein the first path attribute has priority over the second path attribute.
3. The communication apparatus according to claim 1 , wherein the first path attribute represents a quality class of the communication path.
4. The communication apparatus according to claim 3 , wherein the second path attribute represents a service provided to a user.
5. The communication apparatus according to claim 3 , wherein the second path attribute represents a level of traffic congestion.
6. The communication apparatus according to claim 5 , wherein the level of traffic congestion is monitored by a monitoring apparatus.
7. The communication apparatus according to claim 1 , wherein the processor is further configured to execute program instructions to receive the packet from a node terminating the communication path.
8. A communication system, comprising:
a communication apparatus; and
a control apparatus configured to control the communication apparatus,
wherein the communication apparatus comprises:
a memory storing a plurality of quality identifiers; and
a processor configured to execute program instructions to:
receive a packet;
identify, based on the received packet, a first path attribute and a second path attribute corresponding to a communication path of the received packet;
select, based on the first path attribute and the second path attribute, one of the plurality of quality identifiers;
add the selected quality identifier to the received packet; and
forward the received packet including the selected quality identifier.
9. The communication system according to claim 8 , wherein the first path attribute has priority over the second path attribute.
10. The communication system according to claim 8 , wherein the first path attribute represents a quality class of the communication path.
11. The communication apparatus according to claim 10 , wherein the second path attribute represents a level of traffic congestion.
12. The communication system according to claim 11 , further comprising a monitoring apparatus configured to monitor traffic congestion, wherein the level of traffic congestion is monitored by the monitoring apparatus.
13. The communication system according to claim 8 , wherein the processor is further configured to execute program instructions to receive the packet from a node terminating the communication path.
14. A communication method, comprising:
receiving a packet;
identifying, based on the received packet, a first path attribute and a second path attribute corresponding to a communication path of the received packet;
selecting, based on the first path attribute and the second path attribute, a quality identifier from a plurality of quality identifiers;
adding the selected quality identifier to the received packet; and
forwarding the received packet including the selected quality identifier.
15. The communication method according to claim 14 , wherein the first path attribute has priority over the second path attribute.
16. The communication method according to claim 14 , wherein the first path attribute represents a quality class of the communication path.
17. The communication method according to claim 16 , wherein the second path attribute represents a service provided to a user.
18. The communication method according to claim 16 , wherein the second path attribute represents a level of traffic congestion.
19. The communication method according to claim 18 , wherein the level of traffic congestion is monitored by a monitoring apparatus.
20. The communication method according to claim 14 , further comprising receiving the packet from a node terminating the communication path.
