Communication method, transmission apparatus, reception apparatus, and transmission line bandwidth control apparatus for PVC connection type switched network

摘要

The invention provides a communication method for realizing communications between different apparatus in a PVC connection type switched network, which is improved in that PVCs in the inside of the switched network can be set efficiently using preset PVCs dynamically to allow high speed communications without complicating the communication protocol. The communication method is applied to a PVC connection type switched network wherein a plurality of transmission apparatus and at least one reception apparatus are connected to each other by PVC connections by way of an exchange switch which handles fixed length cells. According to the communication method, one or more of the transmission apparatus which have acquired an access right to a PVC to be used performs transmission to the reception apparatus using respective transmission line bandwidths.
