Switch, Switch Cabinet, and Data Switching Method

A switch, comprising:

• at least two interfaces and configured to:
• receive a to-be-forwarded packet;
• and
• send the to-be-forwarded packet based on a first protocol or a second protocol, wherein the at least two interfaces comprise:
• a first interface configured to send and receive a first packet based on the first protocol;
• and
• a second interface configured to send and receive a second packet based on the second protocol, and wherein the to-be-forwarded packet is the first packet or the second packet;
• a multi-protocol conversion apparatus configured to:
• receive the to-be-forwarded packet;
• convert the to-be-forwarded packet into a third packet based on a configuration, wherein the third packet and the to-be-forwarded packet are based on different protocols;
• and
• send the third packet;
• an ingress processing apparatus configured to:
• receive the to-be-forwarded packet;
• obtain indication information corresponding to the to-be-forwarded packet, wherein the indication information indicates a destination interface in each of the at least two interfaces corresponding to the to-be-forwarded packet;
• and
• send the indication information;
• and
• a first switching apparatus configured to:
• receive the third packet and the indication information;
• and
• send the third packet to a corresponding destination interface of the at least two interfaces based on the indication information.

A switch cabinet, comprising:

• a switch comprising:
• at least two interfaces configured to:
• receive a to-be-forwarded packet;
• and
• send the to-be-forwarded packet based on a first protocol or a second protocol, wherein the at least two interfaces comprise:
• a first interface configured to send and receive a first packet based on the first protocol;
• and
• a second interface configured to send and receive a second packet based on the second protocol, and wherein the to-be-forwarded packet is the first packet or the second packet;
• an ingress processing apparatus configured to:
• receive the to-be-forwarded packet;
• obtain first indication information corresponding to the to-be-forwarded packet, wherein the first indication information indicates a corresponding destination interface of the at least two interfaces that corresponds to the to-be-forwarded packet;
• and
• send the first indication information;
• a first switching apparatus configured to:
• receive the to-be-forwarded packet and the first indication information;
• and
• send the to-be-forwarded packet to the destination interface of the at least two interfaces based on the first indication information;
• at least one server electrically connected to the switch;
• and
• at least one resource pool electrically connected to the switch, wherein the at least one resource pool comprises at least one of a plurality of memory resources, a plurality of hard disk resources, and a plurality of accelerator resources.
