IPv6 (Internet Protocol Version 6) message fragmentation recombination method based on multi-thread interaction processing

Abstract

The invention discloses an IPv6 (Internet Protocol Version 6) message fragmentation and recombination method based on multi-thread interaction processing, which comprises the following steps: fragmenting and recombining fragmented messages, and searching in a hash table serving as a global variable according to fragmentation information acquired by analyzing the fragmented messages; storing the fragmentation message into a global variable according to the fragmentation recombination information obtained by searching; and if the packet receiving thread is inconsistent with the packet receiving thread stored in the table entry found in the hash table, sending the fragmented message to a thread scheduling module, scheduling the fragmented message to other packet receiving threads by the thread scheduling module to recombine the received fragments of the same type, and if the fragmented message is consistent with the received fragments of the same type, recombining the fragmented message in a fragment recombining module; and carrying out common message processing on the recombined message. According to the method, the recombination and forwarding efficiency can be improved, the thread state can be switched without entering a blocking state, and resource waste caused by context switching is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to an IPv6 message fragment reassembly method based on multi-thread interactive processing. Background technique [0002] As the basic technology protocol of the next generation network, the purpose of IPv6 is to solve the problem of IPv4 network address exhaustion. In recent years, with the continuous development of technologies such as the Industrial Internet, the Internet of Things, and 5G, the demand for IP address space is increasing. From the commercialization of IPv6 to the comprehensive transformation of the network at the national level to support IPv6, hundreds of millions of IPv6 terminal devices have been connected in my country, and tens of billions of IoT terminals will be connected in the next five years. By 2025, my country will rank first in the world in terms of the three key indicators of network scale, user scale and traffic scale. [0003] With the leapfrog improveme...

AI Technical Summary

Problems solved by technology

[0006] Based on the problems existing in the prior art, the purpose of the present invention is to provide a method for recombining IPv6 message fragments based on multi-threaded interactive processing, which can solve the problem of processing data fragmented messages through software in the existing network function virtualization technology. , when multi-thread reorganizes fragmented packets, there is a problem that the thread state switches to the blocking state and affects the reassembly performance
