Abstract

The embodiment of the present invention discloses an Interest packet forwarding method and device, which are applied to router nodes. The method includes: receiving a target Interest packet sent by a client; the forwarding path of the packet; if it exists, the target interest packet is sent to the response router node through the forwarding path; if it does not exist, the target interest packet is sent to the response router node through each forwarding path in at least two forwarding paths; receiving and Storing the delay for the target Interest packet fed back by the responding router node from each forwarding path; determining the forwarding path with the least delay among the stored delays as the forwarding path for sending the target Interest packet to the responding router node. By applying the embodiment of the present invention, the time delay for sending the target Interest packet through the determined forwarding path is relatively small, and the target Interest packet is sent through the determined forwarding path, thereby improving the forwarding efficiency of the Interest packet.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an Interest packet forwarding method and device. Background technique [0002] At present, the Internet has become the technology and industry with the most extensive influence, the fastest growth and the greatest market potential in the world today. The needs of Internet users have evolved from communication between hosts to repeated access to information from hosts to the network. Users focus on information, not where it is stored. However, the current TCP / IP protocol (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol) architecture cannot adapt to the development of application requirements. In order to completely solve these problems, researchers have designed a new Internet architecture. Information-centric Networking (ICN) is a typical representative of this idea, and it is gradually being considered as the most promisin...
