Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Explanation of terms:

[0032] Packet: It is the basic unit of data transmission in a packet switching network. Consists of header control information and payload data. The present invention includes query data packets and response data packets.

[0033] Protocol-aware forwarding: Network forwarding devices have no awareness of network protocols and data packet processing and forwarding processes, and operations such as reading and writing access to data packets are defined by a set of common network instruction sets, which flexibly define the processing logic of data packets .

[0034]Protocol-aware forwarding device: It is a constituent entity of the forwarding layer in the software-defined network architecture, including several flow tables, each flow table includes multiple flow entries, and each flow entry expresses the rules for proces...

Abstract

The invention discloses a high-speed data query system and method based on protocol awareness-free forwarding. The corresponding protocol-independent forwarding equipment 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 updating function sub-module, a Metadata query function sub-module, a flow table maintenance function sub-module and a routing function sub-module. According to the protocol awareness-free forwarding module based on the DPDK driver, a DPDK development suite is utilized, the sub-module under the module processes a data packet of protocol-independent forwarding equipment, the data packet is read from a hardware driver in a polling mode, and an operating system kernel is bypassed. The system and method have the advantage of high-speed data query.

Description

technical field [0001] The invention relates to a high-speed query 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 uni...
