Protocol conversion system for data communication between different types of open networks
First Claim
1. A protocol conversion system intervening, between a first open type communication network system conforming a first protocol and a second open type communication network system conforming a first protocol and being responsible for sending and receiving communication data therebetween, comprising:
- header adding means for adding to the communication data a header having protocol converting information; and
information including means for including information about success and failure in communication into the header.

Abstract
A protocol conversion system is provided to secure a highly reliable and smooth data communication between different two types of networks whose protocols differs in types from each other. A protocol conversion between such networks is realized by replacing headers added to communication data. Information indicating that sending data was success or failure in transmission is included in the headers, thereby sending results being recognized. A serial interface intervenes between the self and party systems in order to detect states of the party system. Further, for data communication, without processing (or terminating) layers up to an application layer, only lower layers, that is, a transport layer and layers lower than it, are processed (or terminated) to raise reliability in data communication.

4. A protocol conversion system intervening between different types of networks and being responsible for sending and receiving communication data therebetween, comprising:
-
a first node performing communication of data based on a first protocol defining a communication system of a first network;
a second node performing communication of data based on a second protocol defining a communication system of a second network, said second node including a protocol converting means for adding conversion information for conversion to the first protocol, adding control information for control of the first node, and terminating conversion information, for conversion to the second protocol; and
a protocol converter for mutually relaying the communication data between the first and second nodes and for controlling the first node, comprising;
first communication data processing means for processing the communication data to the first node layer by layer;
second communication data processing means for processing the communication data to the second node layer by layer;
node control means not only having serial interface means but also having means for controlling the first node using the serial interface means, monitoring a state of the first node, and notifying the second node of a monitored state of the first node; and
further protocol converting means for terminating the conversion information for conversion to the first protocol, converting to frames recognized by the first node based on the terminated conversion information, terminating the control information for control of the first node, and adding the conversion information for conversion of the communication data from the first node into the second protocol. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
