摘要： Embodiments of the present invention provide a network system and a network communication method. The network system includes: a third-party server and an edge node that are located in a radio access network or an IP transport network between the radio access network and a wireless core network, where the edge node steers a TCP packet that is of user equipment for a central server and that corresponds to a TCP connection to the third-party server, and the third-party server includes an application server or a cache server, and is configured to store delivery data of the central server and respond to the TCP packet according to the delivery data. In the embodiments of the present invention, a cache server or an application server is moved from an IDC equipment room in a metropolitan area network to a local radio access network or an IP transport network between the radio access network and a wireless core network, and an edge node is deployed to steer a TCP packet for a central server to the cache server or the application server, to implement traffic scheduling. In this way, a transmission delay from the radio access network to a packet core network is reduced, thereby improving user experience.

摘要： An I/O board of a VXLAN switch searches out a layer 3 entry; when an egress port in the layer 3 entry is a VXLAN tunnel port, modifies a source MAC address of the packet into a gateway MAC address of the VXLAN switch, modifies a destination MAC address of the packet into a MAC address in the layer 3 entry, and sends the packet to a fabric board of the VXLAN switch. The fabric board determines to perform layer 2 forwarding for the packet, searches out a MAC entry, and when an egress port in the MAC entry is a VXLAN tunnel port, sends the packet to an I/O board associated with the egress port in the MAC entry. The I/O board associated with the egress port adds VXLAN encapsulation to the packet and forwards the packet with the VXLAN encapsulation to a VXLAN.

摘要： A method for operating a mesh network is described. The method includes using a protocol comprising an address and a payload, wherein the address and payload are restricted. The method also includes using a hash function to generate an address from a description, wherein the description uses ASCII characters, wherein a message uses the description as an address and wherein the description is transformed into the address using the hash function and added together with the message into the payload, assigning the generated address to a device, wherein the device is part of a mesh network, and in a transmission from a source to the device, providing the generated address within the payload.

摘要： Embodiments of the present invention provide a remote resource access method and a switching device, so as to implement data transmission between a local computer system and a remote physical resource device, and enable the remote physical resource device to access a computer system using an interrupt manner. The remote resource access method is as follows: When the computer system accessing the remote physical resource device, the switching device converts a virtual address that is of a virtual resource device and that is in a first access message into a corresponding physical address of the remote physical resource device, so as to generate a second access message. Then, the switching device sends the second access message to the remote physical resource device corresponding to the physical address by using a network, thereby implementing the data transmission between the local computer system and the remote physical resource device.
