1. A system comprising:
a plurality of integrated circuits that includes a first integrated circuit and a second integrated circuit that are connected through a die-to-die interface circuit;
a plurality of agent circuits distributed across the plurality of integrated circuits;
a fabric circuit implemented entirely within the first integrated circuit and configured to route packets among a subset of the plurality of agent circuits that are within the first integrated circuit, wherein the fabric circuit corresponds to a first segment of a network that includes a plurality of segments; and
a segment-to-segment (S2S) network interface circuit within the first integrated circuit configured to interface the first segment to one or more additional segments within the network; and
wherein for a given packet having a source agent circuit within the subset and a destination agent circuit external to the first segment, the S2S network interface circuit is a target destination from the perspective of the source agent circuit.
