Communication apparatus, control apparatus, communication method, control method, and program
A technique enabling diverse communication quality control for a communication service is provided. A communication apparatus includes a first means for storing a parameter notified from a control apparatus, wherein the control apparatus can send a control signal related to the communication path to the communication apparatus; and a second means that can perform communication quality control on a packet, based on a quality class of the communication path corresponding to the packet and the parameter corresponding to the communication path.
1. A control apparatus, comprising:
a memory storing a packet forwarding policy for processing a received packet to control communication quality on a communication path, wherein the packet forwarding policy includes a process instruction to add a quality identifier to the received packet; and
a processor configured to execute program instructions to:
identify, based on the communication path, a first path attribute and a second path attribute for the communication path;
identify, based on the first path attribute and the second path attribute, the packet forwarding policy;
send the packet forwarding policy to a switch apparatus on the communication path; and
receive, from a management apparatus, a changing instruction to change one or both of the first path attribute and the second path attribute for the communication path.
2. The control apparatus according to claim 1 , wherein the first path attribute has priority over the second path attribute.
3. The control apparatus according to claim 1 , wherein the first path attribute represents a quality class of the communication path.
4. The control apparatus according to claim 3 , wherein the second path attribute represents a level of traffic congestion.
5. The control apparatus according to claim 4 , wherein the level of traffic congestion is monitored by a monitoring apparatus.
6. The control apparatus according to claim 1 , wherein the second path attribute represents a service provided to a user.
7. The control apparatus according to claim 1 , wherein the management apparatus is configured to manage user information.
8. A network system, comprising:
a communication apparatus; and
a control apparatus configured to control the communication apparatus, comprising:
a memory storing a packet forwarding policy for processing a received packet to control communication quality on a communication path, wherein the packet forwarding policy includes a process instruction to add a quality identifier to the received packet; and
a processor configured to execute program instructions to:
identify, based on the communication path, a first path attribute and a second path attribute for the communication path;
identify, based on the first path attribute and the second path attribute, the packet forwarding policy;
send the packet forwarding policy to the communication apparatus on the communication path; and
receive, from a management apparatus, a changing instruction to change one or both of the first path attribute and the second path attribute for the communication path.
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 system according to claim 8 , wherein the management apparatus is configured to manage user information.
12. A network control method, comprising:
identifying, based on a communication path, a first path attribute and a second path attribute for the communication path;
identifying, based on the first path attribute and the second path attribute, a packet forwarding policy which includes a process instruction to add a quality identifier to a received packet;
sending the packet forwarding policy to a switch apparatus on the communication path; and
receiving, from a management apparatus, a changing instruction to change one or both of the first path attribute and the second path attribute for the communication path.
13. The network control method according to claim 12 , wherein the first path attribute has priority over the second path attribute.
14. The network control method according to claim 12 , wherein the management apparatus is configured to manage user information.
