Abstract
When connecting a plurality of packet processing parts each having a packet processing function as an added function of a virtual network for each user, there was a problem that the number of packet processing units that were connectable, a function of analyzing a communication packet, etc. were dependent on a transport technology of a core network of a virtual network. A communication system including the packet processing unit for performing an information processing of the communication packet on the virtual network has a virtual network system for the packet processing unit in addition to a wide area core network in a wide area network service.
Claims14
A communication system for performing a relay processing between a first network that consists of a plurality of virtual networks whose communication ranges are divided logically and a second network, comprising:
- a network relay processing unit that is connected to the first and the second network and that is constructed with first correspondence information showing a correspondence between a first identifier for identifying the communication packet in the first network and a second identifier for identifying the communication packet in the second network and an identifier conversion part for converting the identifier for identifying the communication packet based on the first correspondence information;
- and
- a packet processing unit that is connected to the second network and that consists of a packet processing part for performing data reference and/or rewrite processing of the communication packet, second correspondence information showing a correspondence between the packet processing part and the second identifier, and a packet distribution part for distributing the received communication packet to the packet processing part based on the second correspondence information.
A network relay processing unit for performing a relay processing between a first network and a second network each of which consists of a plurality of virtual networks whose communication ranges are divided logically,
- comprising:
- an interface connectable to the first network and the second network;
- first correspondence information that shows a correspondence between a first identifier for identifying a communication packet in the first network and a second identifier for identifying a communication packet in the second network;
- and
- an identifier conversion part for converting the identifier for identifying the communication packet based on the first correspondence information.
A management server for managing a relay processing between a first network and a second network each of which is constructed with a plurality of virtual networks whose communication ranges are divided logically,
- comprising:
- a packet processing part assignment part for assigning a packet processing part that performs data reference and/or rewrite processing of a communication packet and is connected to the second network;
- first correspondence information that shows a correspondence between a first identifier for identifying the user's communication packet in the packet processing part being assigned and the first network;
- and
- a second identifier for identifying the user's communication packet in the second network.
