Problems solved by technology

Generally, the network encapsulation function completed by the host is to run the software on the general-purpose processor. On the basis of storage, the data header and payload are completely stored and then encapsulated into a data packet. It is necessary to wait for the entire message to be prepared before sending, and the system delay is very long. Big
At the same time, the delay uncertainty caused by software cannot be ignored

Embodiment Construction

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0015] New communication technologies require lower latency, wider connections, and separation of network control and network transmission. In the new 5G protocol, it is necessary to use low-latency and high-reliability connections to provide wide-area IoT services for Internet of Vehicles, industrial control, etc. These services require extremel...

Abstract

An embodiment of the present invention provides a stacking network processor and a network data stacking processing method. The network processor includes: a storage module, including a header memory and a payload memory, for storing protocol headers and data payloads respectively; a framing module, It is used to obtain the corresponding protocol header and data load from the storage module according to the operation instruction, and after replacing or inserting the preset part of the obtained protocol header, output the data frame to be verified; the verification module is used to verify the After the data frame to be verified is verified, a verification result is obtained; the framing module is further configured to obtain a final data frame according to the data frame to be verified and the verification result, and output it to the network. The network processor does not need to store the entire final data frame before sending it, which can reduce the delay caused by storage. In addition, it is implemented through network hardware modules, which can effectively reduce the calculation delay.

Description

technical field [0001] The invention relates to the technical field of forwarding in a communication system, in particular to a stack-out network processor and a network data out-stack processing method. Background technique [0002] A network processor (NP) is a programmable device that can process data packets and data frames in the network in real time at wire speed, and is widely used in mobile communication, broadband communication, access communication, industrial control, etc. The network processor is also divided into two types: the stack processor and the stack processor. The stack processor unpacks the network data, disassembles, analyzes and processes the header information to obtain the final useful information; and the stack processing The router encapsulates the header information on the data payload after calculation to form a new message, and sends the message out. [0003] Network processors are divided into fast-path processors and slow-path processors. Th...
