Problems solved by technology

However, as the network speed increases to 1Gbps and 10Gbps, the transmission capacity of the network is no longer the main constraint factor.

Embodiment Construction

[0049] The method of the present invention mainly includes six parts: the reorganization principle of the fragment package, the fragment tree, the fragment detection, the classification of the fragment, the advance processing mechanism, and the specific reorganization method.

[0050] 1. Reorganization principle of fragmented package:

[0051] On the host of the destination node, the fragmented packet is reorganized into the original unfragmented form, such as figure 2 (Note: The reassembled data packet does not contain the fragment extension header).

[0052] Reorganization should follow the principle: the original packet can only be reorganized by fragmented packets with the same source address, destination address, and fragment identification. The non-fragmentable part of the reorganized packet is determined by the first fragmented packet (that is, the fragment offset). The packet with a shift of 0) is composed of all the headers (excluding the fragment header) in front of the...

Abstract

The invention relates to a segmentation and reset method based on the Version 6 of a network protocol, which is a method that can improve the transmission performance of the new generation Internet protocol (IPV6) by improving the segmentation and reset efficiency, the specific method includes the following steps: (1) a segmentation and reset system receives a data segment transmitted from a network; (2) the data segment received in step (1) is sent to a segment detection module; (3) the data segment that is not the currently-processed data segment distinguished in step (2) is transmitted to a segmentation tree module for cache, and the segmentation detection module is invoked to guarantee that the segmentation on the branch of the segmentation tree is legal during the branch cache process; 4) the segments passing the authentication in step (2) are transmitted to a segment classification module, and the segments are classified into four types and imprinted with type marks; (5) an advanced processing module is invoked to judge if advanced processing can be carried out, if so, a specific reset module is started to complete the restoration of a data package; otherwise, the data package is transmitted to the segment tree module for cache; and (6) the coming of the next segment is waited and the process is returned to step (1).

Description

Technical field [0001] The invention is a method for improving the transmission performance of a new generation Internet protocol—IPV6 by improving the efficiency of fragmentation and recombination, and belongs to the technical field of network data transmission. Background technique [0002] Web technology promotes the development of the Internet at an astonishing speed. Ten years ago, people who were concerned about the expansion of the Internet in the future began to worry that the limitations of the IPv4 (Internet Protocol Version 4) network itself would be difficult to support the continuous development of the Internet. For this reason, the IETF (Internet Engineering Task Force) has launched a new generation of Internet protocol-IPv6 (Internet Protocol Version 6). Compared with IPv4, IPv6 provides many brand-new features, such as address space expansion, security settings, and automatic configuration. [0003] The development of IPv6 has been supported by many equipment manu...
