Abstract: Examples describe use of multiple meta-data delivery schemes to provide tags that describe packets to an egress port group. A tag, that is smaller than a packet, can be associated with a packet. The tag can be stored in a memory, as a group with other tags, and the tag can be delivered to a queue associated with an egress port. Packets received at an ingress port can be as non-interleaved to reduce underrun and providing cut-through to an egress port. A shared memory can be allocated to store packets received at a single ingress port or shared to store packets from multiple ingress ports.

Abstract: Examples are described herein that relate to a mesh in a switch fabric. The mesh can include one or more buses that permit operations (e.g., read, write, or responses) to continue in the same direction, drop off to a memory, drop off a bus to permit another operation to use the bus, or receive operations that are changing direction. A latency estimate can be determined at least for operations that drop off from a bus to permit another operation to use the bus or receive and channel operations that are changing direction. An operation with a highest latency estimate (e.g., time of traversing a mesh) can be permitted to use the bus, even causing another operation, that is not to change direction, to drop off the bus and re-enter later.
