Embodiment 1

[0053] This embodiment provides an ICN routing method based on interest-based network slicing, that is, the network is segregated according to the user's interest, so that the data content that the user is interested in can be quickly searched.

[0054] image 3 It is a flow chart of using the ICN routing method based on interest network fragmentation according to Embodiment 1 of the present invention, including the following steps:

[0055] Step S301: the global controller obtains historical interest data packets of at least one switch in the network;

[0056] In the embodiment of the present invention, there is at least one switch in the network, and each switch stores the historical interest data packets of interest requests sent by multiple users, and the global controller will extract the historical interest data packets in at least one switch. The data package can represent the interest collection of most users, and it is of reference significance to classify user inter...

Abstract

The invention discloses an ICN routing method and an ICN routing system based on an interested network fragment. The method comprises the steps as follows: a client sends an interest request to a network, wherein the interest request is used for requesting for data content in which the user is interested; a switch determines a target interested fragment according to the interest request; the switch determines a target fragment controller corresponding to the target interested fragment; the switch uploads the interest request to the target fragment controller in the target interested fragment network; the target fragment controller searches the data content in which the user is interested; and the switch transmits the data content in which the user is interested to the client. According tothe method and the system provided by the invention, the data content in which the user is interested can be found in the interested fragment network, the finding efficiency can be improved, and the content hit rate can be further improved; the data is transmitted via the optical transmission path, and the hop count reduction rate and the bandwidth utilization rate can be improved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an ICN routing method and system based on interest network fragmentation. Background technique [0002] The Internet with the TCP / IP protocol stack as the main architecture has deficiencies such as fixed structure, poor scalability, and limited mobility support, and cannot adapt to the development needs of the future Internet. Therefore, people have proposed a variety of future Internet architectures, which are representative It is an information-centric network (ICN). The main idea of ​​ICN is to reduce the transmission delay of data by caching the content to the node closer to the user, and at the same time reduce the consumption of network bandwidth and server load. This communication mechanism based on direct addressing and routing of content names faces many challenges in deploying applications. Existing ICN routing technologies, such as full forwarding, random f...
