Buffer management within SLS (simple load store) apertures for inter-endpoint communication in advanced switching fabric

A buffer management method in an advanced switching fabric comprising:

• checking if an empty flag for a descriptor at a write indicator is set;
• filling a length and data offset field in the descriptor;
• updating the empty flag;
• incrementing the write indicator;
• and
• filling a route field with a destination.

An article of machine-readable medium containing instructions that, when executed, cause a machine to:

• divide a simple load and store memory aperture into a buffer descriptor and at least one data buffer;
• provide offset addressing in the buffer descriptor;
• and
• access the buffer descriptor by more than one endpoint to allow direct memory access with multiple endpoints in a simple load and store memory aperture.

A system comprising:

• a first endpoint in an advanced switching fabric;
• a second endpoint in the advanced switching fabric;
• and
• a memory associated with the first endpoint, the first endpoint to divide the memory into a buffer descriptor and at least one data buffer, and to store offset address information in the buffer descriptor such that the second endpoint can access a data buffer in the memory.
