The embodiments of the invention provide a method, a device and a system for dynamic arranging network functions. The method comprises the steps of: receiving data packets; initializing non-retransmitted data packets, comprising: sending a network function execution chain identifier and network function unit information required to be executed for executing first-turn network function pipeline traversal to the data packets; traversing network function units in turn according to a network function pipeline to trigger the network function units that need to execute actions to process the data packets; if all network functions in a network function execution chain of the data packets are not completely executed, repeating the above steps based on the retransmitted data packets; and after allthe network functions in the network function execution chain are completely executed, outputting the data packets. The method, device and system for dynamically arranging network functions simplifyprogramming of programmable data planes through the modular network function units, and dynamically arrange the network functions during operation through virtual control logics.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of the Internet, specifically a method, device and system for dynamically programming network functions. Background technique [0002] In traditional networks, due to issues such as complex design and hardware process limitations, it often takes several years to add new functions or new network protocols to switching chips, making it difficult for network equipment to meet the development requirements of rapid new protocols and network protocols. Aiming at the challenge of slow evolution of network equipment, the team led by Professor Nick MckWeon of Stanford University proposed a protocol-independent programmable data plane architecture. Based on the reconfigurable matching action table, the architecture builds a protocol-independent data packet processing pipeline through programmable control logic, and can quickly add new network functions to the switching chip. Through the prog...
