Abstract
A device includes a port to couple to another device over an interconnect, where the port includes circuitry to: identify a receiver usage limit for a given virtual channel of a link to be implemented on the interconnect; generate a link layer packet, where the link layer packet includes a field to indicate the receiver usage limit; and send the link layer packet to the other device over the link.
Claims20
An apparatus comprising:
- a port to couple to another device over an interconnect, wherein the port comprises circuitry to:
- identify a receiver usage limit for a given virtual channel of a link to be implemented on the interconnect;
- generate a link layer packet, wherein the link layer packet comprises a field to indicate the receiver usage limit;
- and
- send the link layer packet to the other device over the link.

An apparatus comprising:
- a port to couple to another device over an interconnect, wherein the port comprises circuitry to:
- identify a first usage limit for a given virtual channel of a link to be implemented on the interconnect;
- transmit data on the given virtual channel based on the first usage limit;
- receive, on the link, a data link layer packet (DLLP), wherein the DLLP comprises a field to indicate a second usage limit for the given virtual channel associated with a receiver of the other device;
- and
- transmit data on the given virtual channel based on the second usage limit.
3 more elements
A system comprising:
- a first device;
- and
- a second device coupled to the first device by an interconnect, wherein the second device comprises a port to couple to the interconnect, and the port comprises circuitry to:
- identify a receiver usage limit for a given virtual channel of a link to be implemented on the interconnect;
- generate a link layer packet, wherein the link layer packet comprises a field to indicate the receiver usage limit;
- and
- send the link layer packet to the other device over the link.
