Background technique

Information centre's network (Information-centric networking, ICN) is to obtain information as core purpose network.ICN network is interest (interest) packet and the content-data packet for responding the interest packet respectively there are two types of core data packet, abbreviation data packet, includes the requested data content of interest packet in the data packet.

Each ICN node in information centre's network is stored with forwarding information table (Forwarding information base, FIB) and forwarding required list (Pending interest Table, PIT), FIB is used to inquire next forward node of interest packet, (its principle is the port that record receives interest packet to next transmission node of the PIT for inquiring data packet, this port is recorded in PIT, data packet just returns to request of data end according to the original route that interest packet is sent by this port.

Each ICN node further includes content storage (Content Store, CS) module, and when data packet passes through the ICN node, ICN node can be automatically by the storage of this data packet into CS module.

Data transmission procedure in ICN is described by taking Fig. 1 as an example:

Step 1:ICN node 1 sends content needed for an interest packet is requested.

After step 2:ICN node 2 receives interest packet, since this node does not have requested content, required content can not be thus provided, ICN node 2, which determines inquiry fib table, is transmitted to next node ICN node 3 for this interest packet, and by original route in ICN node 2, that is, ICN node 2 receives the port of interest packet and is recorded in PIT table.

After step 3:ICN node 3 receives interest packet, the same original route that records is into PIT table.Due to being stored with requested content in itself in ICN node 3, then inquiring PIT table and finding original route is ICN node 2, and the content is returned to ICN node 2 in the form of data packet.

, can be the content caching received after step 4:ICN node 2 receives the data packet, that is, storage is into the CS module of itself.Then the PIT table that ICN node 2 can inquire itself finds original Path is ICN node 1, and data packet is finally sent to ICN node 1.Thus a data transmission procedure is completed.
