Problems solved by technology

[0012] The length of the IP data packet in IPv6 is variable based on the byte, which can range from the minimum byte to the maximum 65536 bytes, but this leads to the inability of the data to be self-delimited, that is, the corresponding data cannot be distinguished in a pure IP data stream. The location of the IP header and data information must be carried by other technical methods (such as Ethernet MAC frames, HDLC, ATM cells, etc.) in order to be transmitted on the link and delimited normally

Abstract

The invention discloses a method for granulating and delimiting IP envelopes, which relates to the technology of data transmission network and network link layer IP packet encapsulation in the communication field. The present invention granulates IPv6 data packets into IP envelopes, specifies k=1 granulated IP delimited envelopes, and adopts granulated IP delimited envelopes to delimit link data. The present invention is suitable for different application occasions such as wired network and wireless network, achieves self-delimitation of envelopes at the link layer, simplifies the underlying bearer, high encapsulation efficiency, good support performance for voice services, good interoperability with IPv6, and simplifies data exchange It has the advantages of front-end processing and strong expansibility, and is especially suitable for building a data and voice mixed transmission network system.

Description

technical field [0001] The invention relates to a method for granulating and delimiting IP envelopes in the communication field. It is especially suitable for constructing data and voice mixed transmission network system in optical fiber internet, wireless internet, satellite communication network and other dedicated high-speed switching networks. Background technique [0002] In recent years, with the advancement of informatization in various countries in the world, the Internet based on the TCP / IP protocol is facing more and more challenges and problems while achieving great success. The root cause of these challenges and problems is The existing IPv4 protocol used by the Internet has many design defects. Compared with IPv4, the proposal of IPv6 has the following improvements and advantages: 1) expansion of address space; 2) simplification of header format; 3) introduction of extended header! Better support for mobility and security; 4) Introduce mechanisms such as flow ...
