Implementing Control Using A Single Path In A Multiple Path Interconnect System
First Claim
1. A method for implementing control using a single path in a multiple path interconnect system comprising:
- providing a transport layer (TL) with each source interconnect chip and each destination interconnect chip;
providing a control TL message to transfer control information between a respective pair of a source transport layer (TL) with a source interconnect chip and a destination transport layer (TL) of a destination interconnect chip; and
providing a respective TL message port identifying a port used to send and receive the control TL message for said source TL and said destination TL;
said respective TL message port defining the single path.

Abstract
A method and circuit for implementing control using a single path in a multiple path interconnect system, and a design structure on which the subject circuit resides are provided. Control TL messages include control information to be transferred between a respective source transport layer of a source interconnect chip and a destination transport layer of a destination interconnect chip. Each transport layer (TL) includes a TL message port identifying a port used to send and receive control TL messages for a pair of source TL and destination TL. The respective TL message port of the pair of source TL and destination TL defines the single path used for control messages.
