Problems solved by technology

However, the Linux kernel protocol stack does not consider its own processing performance too much when setting it up, and due to reasons such as locking, in the case of multi-core concurrency, the processing performance of the Linux kernel protocol stack drops sharply

Embodiment Construction

[0024] At present, with the development of Data Plane Development Kit (DPDK: Data Plane Development Kit), user-mode sending and receiving packages represented by DPDK are gradually becoming mainstream. The so-called sending and receiving packets in user mode represented by DPDK refers to bypassing the Linux kernel protocol stack through DPDK and directly sending, receiving and processing packets in user mode. DPDK provides library functions and driver support for efficient sending and receiving packets in user mode.

[0025] DPDK is a packet forwarding processing suite, but it is not a network protocol stack, and does not provide Layer 2 and Layer 3 forwarding functions. When running DPDK in the kernel mode of the network operating system, it is also necessary to run the protocol stack in the kernel mode.

[0026] In an example, the protocol stack in the user mode is mainly applied in the following two models: a shared model and an exclusive model. The following are analyzed...

Abstract

The invention provides a network operating system and a message forwarding method. In the application, the network operating system fuses the sharing model and the exclusive model to realize coexistence of the protocol stack (called the sharing protocol stack and the first protocol stack) in the sharing model and the protocol stack (called the exclusive protocol stack and the second protocol stack) in the exclusive model. Due to coexistence of the shared protocol stack and the exclusive protocol stack, a network operating system can support various services and can meet the requirement for high performance.

Description

technical field [0001] The application relates to network communication technology, in particular to a network operating system and a message forwarding method. Background technique [0002] With the popularization of smart devices, many application programs (APP) have a very large number of users, and some APPs even have hundreds of millions of users, which has high requirements on the performance of the network operating system that carries the APP in the smart device. [0003] The processing performance of the protocol stack in the network operating system reflects the performance of the entire network operating system. Currently, in network operating systems, the commonly used protocol stack is the Linux kernel protocol stack. However, the Linux kernel protocol stack does not consider its own processing performance too much when setting it up, and due to reasons such as locking, in the case of multi-core concurrency, the processing performance of the Linux kernel protoc...
