Embodiment

[0174] This embodiment provides an NDN multi-port forwarding method. The port weight value in this embodiment takes the score as an example. The process of the method provided by this embodiment is as follows Figure 7 shown, including:

[0175] When the router receives the data packet, it judges that the received data packet is an interest packet or a content packet. If it is an interest packet, check whether the content packet requested by the interest packet is stored in the locally stored CS table. If there is a content packet stored, return the content If there is no matching content package, then further query the local PIT table to determine whether there are other Interest packets requesting the same content in the local PIT table (that is, whether there are already Interest packets from other ports requesting this content), such as If there are other Interest packets requesting the same content in the local PIT, update the matching item in the PIT. The specific update...

Abstract

The invention is applicable to the communication field, and provides an NDN multiport forwarding method and a router. The method comprises the following steps: when an interest packet is forwarded, a matching item matching the interest packet is queried in a local forwarding information table (FIB), so as to acquire a plurality of ports corresponding to the matching item; according to weighted values of the plurality of ports, several ports are selected from the plurality of ports for forwarding the interest packet; and based on whether a port of a forwarded interest packet receives a returned content packet matching the interest packet, the weight value of the port of the forwarded interest packet is updated. According to the technical scheme of the invention, the advantages of reducing the interest packet flooding and improving the forwarding efficiency are realized.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a forwarding method and router based on content network multi-port. Background technique [0002] The changes in the production, dissemination, acquisition, and use of information and content are the most important changes that the Internet has brought to people's lives. Various Internet-based applications emerge in endlessly, most of which are related to "content". According to the 26th China Internet Development Statistical Report released by the China Internet Network Information Center in July 2010, online music, online news, Search engines, instant messaging, online games, online video, e-mail, blog applications, social networking sites, and online literature are currently the most important types of network applications. In June 2010, the usage rates of two traditional information acquisition applications, Internet news and search engines, reached 78.5% and 76.3%, res...
