Latest Patents

Kumazaki holds a patent for a "Converter and communication control method." This invention is designed to connect ATM networks with other ATM networks through a Local Area Network (LAN). The converter features an address translation table that stores external Virtual Path Identifiers (VPIs), internal VPIs assigned to the LAN, and corresponding MAC addresses for opposing converters. The processing unit within the converter performs control functions to transmit frames modified from external VPI/VCIs of headers of cells from its ATM network to internal VPI/VCIs. This is achieved by referencing the address translation table and attaching the appropriate MAC addresses. Additionally, it removes opposing MAC addresses from frames received from the LAN and transmits cells modified from internal VPI/VCIs back to external VPI/VCIs.
