High-speed data updating system and method based on protocol awareness forwarding

Abstract

The invention discloses a high-speed data updating system and method based on protocol awareness-free forwarding. The corresponding protocol is independent of forwarding equipment; the system comprises a protocol awareness-free forwarding module based on DPDK driving. The protocol awareness-free forwarding module is used as a module based on DPDK driving to operate in a user state. The protocol awareness-free forwarding module comprises a function plane sub-module, a Metadata query function sub-module, a Metadata updating function sub-module, a flow table maintenance function sub-module and arouting function sub-module. According to the protocol awareness-free forwarding module based on the DPDK drive, a DPDK development suite is utilized, the sub-module under the module processes a datapacket of protocol-independent forwarding equipment, the data packet is read from network card hardware equipment in a polling mode, and an inner core of an operating system is bypassed. The method has the advantage of updating data at a high speed.

Description

technical field [0001] The invention relates to a high-speed update system and method based on protocol-free forwarding, and belongs to the technical field of software-defined networks. Background technique [0002] Software-defined networking separates network control and forwarding, provides a centralized control plane, and monitors, configures, and manages the entire network. The software-defined network is an innovation to the traditional network architecture. The software-defined network architecture is divided into the application layer, the control layer and the forwarding layer. The physical entity corresponding to the forwarding layer is a protocol-aware forwarding device, and the physical entity corresponding to the control layer is a network controller. The protocol-aware forwarding device is responsible for the high-speed forwarding of network data, and its forwarding decision comes from the network controller. The network controller conducts centralized and un...
