Multiplexing/demultiplexing on a shared interface
View Patent ↗An embodiment of an interface system including, among others, an aggregation device comprising a plurality of ports, a first device comprising a plurality of ports, and one or more links that link the entire plurality of ports of the aggregation device and first device, the one or more links fewer in quantity than the entire plurality of ports.
1. A system, comprising:
an aggregation device comprising a plurality of ports;
a multi-port device comprising a plurality of ports; and
one or more links that link the entire plurality of ports of the aggregation device and multi-port device, the one or more links fewer in quantity than the entire plurality of ports, and wherein the multi-port device and the aggregation device are configured to exchange information responsive to congestion at the multi-port device, wherein the information is exchanged autonomously, by a polling mechanism, or a combination of both, and wherein the polling mechanism comprises an exchange of an opcode corresponding to a status query and an exchange of a status report comprising port information for the entire plurality of ports.
2. The system of claim 1 , wherein the multi-port device further comprises a plurality of xDSL ports in addition to the plurality of ports.
3. The system of claim 1 , wherein the one or more links each comprise one or more logical sublinks.
4. The system of claim 1 , wherein the one or more links comprises one of a media independent interface (MII) link, a serial media independent interface (SMII) link a gigabit media independent interface (GMII) link, a serial gigabit media independent interface (SGMII) link, a reduced gigabit media independent interface (RGMII) link, and a SerDes link.
5. The system of claim 1 , wherein the aggregation device comprises a multiplexing module configured to associate a packet received from an upstream device with a channel of the one or more links.
6. The system of claim 5 , wherein the channel comprises logical subdivisions corresponding to one or more parameters.
7. The system of claim 6 , wherein the one or more parameters include one or more of a port, a latency with the port, and a priority with the port and latency combination.
8. The system of claim 6 , wherein the multiplexing module is configured to uniquely address each of the logical subdivisions.
9. The system of claim 1 , wherein the information is exchanged in-band along the one or more links.
10. The system of claim 9 , wherein the information exchanged in-band comprises non-data bits and superframes.
11. The system of claim 9 , wherein the information exchanged in-band is one of communicated in one of an interframe gap of a preamble and encoded in reserved addresses of a packet.
12. The system of claim 1 , wherein the information is exchanged out-of-band separate from the one or more links.
13. The system of claim 1 , wherein flow control information is communicated between the aggregation device and the multi-port device using pause frames having a destination address that differs from a standards-based pause frame.
14. The system of claim 1 , wherein flow control information is communicated between the aggregation device and the multi-port device according to proprietary mechanisms, wherein the proprietary mechanisms include one of an associated mechanism and a non-associated mechanism.
15. A method, comprising:
exchanging first packets of data between a first port of an aggregation device and a first port of a multi-port device over logical sublinks of a single physical link; and
exchanging second packets of data between a second port of the aggregation device and a second port of the multi-port device over the logical sublinks of the single physical link, wherein exchanging the first and second packets are performed responsive to congestion at the multi-port device, wherein the first and second packets are exchanged autonomously, by a polling mechanism, or a combination of both, and wherein the polling mechanism comprises an exchange of an opcode corresponding to a status query and an exchange of a status report comprising port information for the ports.
16. The method of claim 15 , wherein the single physical link comprises one of a media independent interface (MII) link, a serial media independent interface (SMII) link a gigabit media independent interface (GMII) link, a serial gigabit media independent interface (SGMII) link, a reduced gigabit media independent interface (RGMII) link, and a SerDes link.
17. A system, comprising:
means for classifying and scheduling packets;
means for reporting a congestion status on a per-packet basis; and
means for sharing a single channel to send the packets to multiple destinations based on the congestion status, wherein information is exchanged autonomously, by a polling mechanism, or a combination of both, and wherein the polling mechanism comprises an exchange of an opcode corresponding to a status query and an exchange of a status report comprising port information for a plurality of ports.
