PACKET NETWORK WITH COMMUNICATION RESOURCE ALLOCATION AND CALL SET UP CONTROL OF HIGHER QUALITY OF SERVICE

摘要

A packet network in which the qualities of service can be maintained for different communications of different classes of requirement for quality of service, regardless of types of calls and data. In this packet network, a communication resource is subdivided into sub-resources which are to be allocated to communications classified into communication classes, where an amount of communications within each sub-resource is controlled independently to satisfy a required quality of service. Also, first type of calls for which a ratio of a maximum transfer speed of each call with respect to a transfer speed of multiplexed line of the packet network is greater than a predetermined threshold value, and second type of calls which are not the first type of calls are distinguished, and a priority control to favor the first type of calls over the second type of calls is performed.
