Abstract: This application provides a packet transmission method and apparatus. The method includes: receiving, by a first transmission device, a first VXLAN packet sent by a first service device through a first virtual extensible local area network VXLAN tunnel; determining, by the first transmission device, first egress information corresponding to a first BD and a first destination media access control MAC address, based on a correspondence between the first BD, the first destination MAC address, and the first egress information; generating, by the first transmission device, a second VXLAN packet based on the first VXLAN packet and the first egress information, where the second VXLAN packet includes a second VNI and an Ethernet frame; and sending, by the first transmission device sends the second VXLAN packet to a second transmission device through a second VXLAN tunnel. This application facilitates more flexible packet transmission.

Abstract: A data write method includes: obtaining a first logical address of first data; determining whether second data is stored in a storage pool, where a logical address of the second data is the same as the first logical address; and when the second data is stored in the storage pool, writing the first data to a first logical block set of the storage pool, where the first logical block set is used for storing hot data.

Abstract: A packet transmission method includes: receiving, by a forwarding device through a port, a protocol packet from another forwarding device or user equipment; performing, by the forwarding device, virtual extensible local area network VXLAN encapsulation on the protocol packet to generate a first VXLAN packet, where the first VXLAN packet includes the protocol packet and the port information; and sending, by the forwarding device, the first VXLAN packet to the controller.
