Abstract

The present invention provides an uplink data packet forwarding method and device, a downlink data packet forwarding method and a device of the present invention, the kernel network interface is provided with an interface attribute, the interface attribute includes an interface name and an interface type, and the interface type includes a local area network interface and a wide area network interface; When the interface type is a LAN interface, the kernel network interface is also provided with an interface label, and the interface label includes an interface name and an interface number; the uplink data packet forwarding method includes: the kernel network interface whose interface type is a LAN interface receives a packet to be forwarded; The interface number of the interface determines whether the state of the receiving interface is bound; if so, add the interface mark of the kernel network interface in the data packet to be forwarded, and forward the data packet to be forwarded after adding the interface mark to the interface type of the WAN interface Kernel network interface. The forwarding process of the uplink or downlink data packet forwarding method is simple, the forwarding is accurate, and the efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an uplink data packet forwarding method and device, and a downlink data packet forwarding method and device. Background technique [0002] The rapid development of Internet network traffic, scale and application poses a major challenge to the design of Internet core routers. With the increasing bandwidth of optical fiber transmission and the number of hosts connected to the network, the switching capacity and port density of routers are difficult to meet the increasing demands of network traffic. With the rapid expansion of the network scale, the forwarding capability of routers is difficult to adapt to the exponential growth of FIB (Forward Information Base, Forwarding Information Base) capacity. With the development of IPv6, QoS (Quality of Service, quality of service), multicast, security and other applications, the packet processing capability of routers is dif...
