Data transmission protocol and its control method point-to-point connetion in inter connetion network

摘要

The present invention relates to a point-to-point connection protocol and a control method in an interconnection network. In particular, in a parallel computer using an interconnection network consisting of a point-to-point connection, automatic separation and coupling of nodes without additional signal lines between a dedicated diagnostic network or a point-to-point connection The present invention relates to a point-to-point connection protocol and a control method supporting recognition.;In general, the interconnection network of a parallel computer supports the separation and coupling of point-to-point connections in an uninterrupted state to ensure high availability of the system. To this end, a diagnostic dedicated network is separately configured and operated to monitor and determine whether a node or a connection medium is disconnected, or a special signal line is used to define separation and coupling between point-to-point connections. However, in the above case, there is a disadvantage in that an additional cost is required in hardware configuration. The present invention provides a protocol and a control method for lowering hardware implementation cost in a parallel computer interconnection network configuration and recognizing separation and combination of point-to-point connections without using a specific signal between a diagnostic-only network or a point-to-point connection.
