A ccn subnet mobile data transmission method

Abstract

The invention discloses a CCN subnet mobile data transmission method. The method comprises the steps that each access router in a CCN domain broadcasts a mobile discovery message in real time; when a mobile router enters the CCN domain for the first time and receives the mobile discovery message, identification information in the mobile discovery message is extracted a default router is established, self identification is subjoined, the mobile discovery message is upgraded and is broadcasted in the subnet; when the mobile router enters another router and detects that the current received discovery message is different from last time, the identification information of the discovery message is extracted, a default router is established, self identification is subjoined, the mobile discovery message is upgraded and is broadcast in the subnet; a node in the subnet detects that the mobile discovery message sent by the mobile router is different from last time, a waiting request is sent again; the access router responds to the received request and returns data to a corresponding request node. The method supports drive type mobile discovery of mobile nodes in the subnet.

Description

technical field [0001] The invention relates to a CCN data transmission method, in particular to a CCN subnet mobile data transmission method, which belongs to the technical field of computer network communication. Background technique [0002] With the rapid development of information technology, new Internet applications emerge in an endless stream, causing traditional IP technology to face many challenges. In particular, the rapid development of mobile communication technology and the emergence of emerging data applications such as the Internet of Things and cloud computing are gradually changing the traditional mode of Internet users' access to service resources, making the Internet gradually develop from the basic functions of interconnection to supporting massive data interaction. , and pose new challenges to network security and efficient mobility. [0003] In recent years, researchers have used many methods and means to improve and optimize the existing Internet to ...

AI Technical Summary

Problems solved by technology

[0008] In the case of subnet movement, the CCN communication mode will not be able to trigger the node to resend the request packet in time because the movement of the mobile router is transparent to the nodes in the subnet, which will cause a huge switching delay (the node can only pass the request message timeout to trigger the re-request process)
