Abstract

The invention provides an internal network interface mapping method and an internal network interface mapping device supporting the separation of forwarding and control. The method comprises the following steps of: loading a virtual network interface driver; transmitting a message by adopting the virtual network interface driver; receiving the message by adopting the virtual network interface driver; and unloading the virtual network interface driver, wherein a virtual network interface is between a forwarding plane and a control and management plane. By the method and the device, normal communication between control hardware and forwarding hardware can be ensured when the forwarding is separated from the control.

Description

technical field [0001] The invention relates to switch technology, in particular to an internal network interface mapping method and device supporting separation of forwarding and control. Background technique [0002] At present, the routing switch can be logically divided into three planes, namely, the forwarding plane, the control plane and the management plane. The main task of the forwarding plane of the routing switch is to process and forward various types of data on different ports of the switch, mainly including forwarding hardware and low-level software. The data plane of the switch needs to occupy most of the various plane tasks of the switch. The resource also directly plays a decisive role in the performance of the switch. [0003] The control plane of the routing switch is used to control and manage the operation of all network protocols, such as spanning tree protocol, virtual local area network (Virtual Local Area Network, VLAN) protocol, address resolution ...
