Embodiment Construction

[0032] Embodiments of methods and apparatus for managing peer-to-peer communications in a serial-based interconnect fabric environment, such as an Advanced Switching (Advanced Switching AS) environment, are described herein. In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, component materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail so as not to obscure the invention.

[0033] Throughout this specification, "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described with respect to that embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases "in one embod...

Abstract

A peer-to-peer connection protocol for establishing and managing peer-to-peer connections between endpoints coupled via a serial-based interconnect fabric. A requesting endpoint generates and sends a query to a fabric manager requesting connection information for at least one target endpoint having attributes matching attributes specified in the query. The fabric manager returns a query reply containing connection information to connect the requesting endpoint to a target endpoint or multiple target endpoints having matching attributes. In the case of multiple target endpoints, one target endpoint is selected for the connection. The requesting and target endpoints then negotiate and establish the connection by passing connection information and parameters between themselves directly. Upon establishing the connection, the fabric manager is apprised of the new connection and updates its connection list. The method is facilitated by software components running on various devices coupled to the serial-based interconnect fabric. Such devices include server blades and ATCA boards. In one embodiment, the serial-based interconnect fabric comprises an Advanced Switching (AS) fabric.

Description

technical field [0001] The field of the invention relates generally to computer and processor-based systems, and more particularly, but not exclusively, to methods for facilitating the management of peer-to-peer communication links by serial-based interconnect fabrics Technology. Background technique [0002] The communications industry faces two clear trends: a greater concentration of computing technology and a changing value chain that stimulates the development and application of modular platforms for deployment - complex, convergent solutions. Adding to this trend is the realization that the silicon industry at the interconnect level is no longer divided into computers and communications, as it has historically been. Furthermore, the current situation in the silicon industry is more like a body of component manufacturers that care about balancing overall industrial investment in order to reduce costs and follow market trends. In combination, these influence the choice...
