Abstract

In one embodiment, the present invention includes a method for receiving a request in a router from a first endpoint coupled to the router, where the request is for an aggregated completion. In turn, the router can forward the request to multiple target agents, receive a response from each of the target agents, and consolidate the responses into an aggregated completion. Then, the router can send the aggregated completion to the first endpoint. Other embodiments are described and claimed.

Claims16

Dependent claims

An apparatus comprising:

a router including a plurality of interfaces each to couple to one or more of a plurality of endpoints and to route requests received from the plurality of endpoints to at least one destination endpoint, the router including an aggregation logic to, responsive to an aggregation request from a first endpoint, combine a plurality of responses received from at least some of the plurality of endpoints into a combined response and to send the combined response to the first endpoint, the aggregation request including an aggregation indicator corresponding to a predetermined source port identifier to indicate a request for the combined response, wherein the predetermined source port identifier is reserved for use by the plurality of endpoints for issuance of aggregation requests.

Dependencies are inferred from the claim text.
