Abstract
A communication quality control system for deciding an optimum communication quality in a received datagram to transfer the datagram, in which not only a destination is decided according to the data of the protocol layer 3 and beneath included in the datagram, but also attribute information of communication is taken out by an attribute detecting unit, according to the information of the respective protocol layers 4, 5, 6, and 7 or one of them, and communication quality for sending the datagram is decided by a communication quality deciding unit and a connection communication quality control unit, according to the quality information of connection corresponding to the attribute information taken out.
Claims33
A communication quality control system for realizing an optimum datagram transfer function for connection quality corresponding to attributes of communication, comprising:
- network end systems for respectively terminating a protocol layer of an existent data network;
- protocol end systems for respectively terminating the protocol layer 3 and beneath based on quality of communication of a received datagram;
- and
- a communication datagram transfer system for transferring the datagram to a specified end system according to quality information of a connection corresponding to communication attributes of the protocol layer 3 and beneath and communication attributes derived from the information on the respective protocol layers 4, 5, 6, and 7 or one of them included in a datagram received by an arbitrary end system,
- said communication datagram transfer system including
- attribute detecting means of checking identifying information included in the information of the protocol layer 3 and beneath of a datagram received by some end system and simultaneously checking identifying information included in the information of the respective protocol layers 4, 5, 6, and 7 or one of them, hence to take out the communication attribute information of the respective protocol layers, and
- communication quality deciding means for, when a datagram is received by a protocol end system, deciding communication quality for sending the datagram according to a set of the communication attribute information of the respective protocol layers derived from the datagram and the quality information of a connection, and notifying the communication quality to said protocol end system.
