Parallel user state protocol stack management method and protocol stack system

Abstract

Embodiments of the present invention provide a method for managing parallel user mode protocol stacks and a protocol stack system, and the method comprises: monitoring the running state of the instance corresponding to each protocol stack of the user mode protocol stacks, one instance corresponding to one protocol stack of the user mode protocol stacks; determining a first instance and a second instance, wherein the first instance is the instance in an abnormal running state, and the second instance has the capability of moving into at least one load to be migrated in the first instance; and re-establishing the at least one load to be migrated in the second instance according to a PCB in a shared resource pool, wherein the PCB corresponds to the at least one load to be migrated in the first instance. In the embodiments of the present invention, as the load to be migrated is reestablished in the instance with the capacity of moving into the load according to the PCB in the shared resource pool, wherein the PCB corresponds to the load to be migrated in the abnormal instance, the system distributing bottleneck caused by the protocol stacks sharing one distributing module is overcome, and the load balance and failure recovery are quickly performed, and therefore the performance of the protocol stack system is improved.

Description

technical field [0001] The embodiments of the present invention relate to the computer field, and more specifically, relate to a management method and a protocol stack system of a parallel user state protocol stack. Background technique [0002] With the development of Ethernet technology and the emergence and popularization of 10G and 40G network cards, the traditional single-core-based protocol stack can no longer keep up with the speed of network cards. In addition, the processor architecture has evolved from emphasizing high-frequency single processors to multi-core multi-processors, and the parallel processing capabilities of computers are becoming stronger and stronger. [0003] In the prior art, when data packets are distributed among multiple protocol stack instances, a common distribution module is used to distribute data at the granularity of connection. The distribution module may become the distribution bottleneck of the system, and maintenance is required during...

Problems solved by technology

[0003] In the prior art, when data packets are distributed among multiple protocol stack instances, a common distribution module is used to distribute data at the granularity of connection. The distribution module may become the distribution bottleneck of the system, and maintenance is required during load balancing and load fault recovery. A large amount of data consumes more system time, which is not conducive to the rapid recovery of load connection data
