Communication chip and data switching apparatus

A data switching apparatus, wherein the data switching apparatus comprises a backplane and at least one communication chip disposed on the backplane, wherein the at least one communication chip comprises:

• a plurality of switching dies and a plurality of network processing dies, and wherein:
• any one of the plurality of switching dies is connected to another switching die, any one of the plurality of network processing dies comprises an external port and an internal port, wherein the internal port is connected to another network processing die, or the internal port is connected to both another network processing die and one of the plurality of switching dies;
• and
• any one of the plurality of network processing dies is configured to:
• receive a first packet from outside of the communication chip via the external port;
• obtain destination information of the first packet;
• and
• send a second packet via the internal port, wherein the second packet comprises the first packet and the destination information, and the destination information indicates a destination network processing die of the first packet;
• any one of the plurality of switching dies is configured to:
• receive the second packet;
• and
• send the second packet to a connected switching die when determining, based on the destination information, that a preset condition is not satisfied;
• or
• send the second packet to a connected first network processing die when determining that the preset condition is satisfied;
• and
• the first network processing die is configured to:
• receive the second packet from the connected switching die;
• and
• send the second packet to outside via the external port;
• or
• send the second packet to the another network processing die via the internal port,
• wherein the preset condition comprises:
• the any one of the plurality of network processing dies is a switching die in the plurality of switching dies that is connected to the destination network processing die;
• or
• the any one of the plurality of network processing dies is a switching die that is connected to the destination network processing die via the another network processing die and that is connected to a minimum quantity of connected network processing dies.
