A name based Network is a network where a node has a set of named objects which also gets named objects own by other nodes. A name is composed by a unique identifier of the node in the network that has it, followed by a subname localy unique attributed by the node. Each node has a cache memory with capacity to store a small amount of objects. The network topology is a tree.
When a user of a origin node wants to find a specific node, that node sends a intereset message with the name of that object. The intereset message is forward in the network in direction of the node that contains the object. The destination node or other intermidiate that has the the object stored in its cache answers to the intereset message with an object message contacining the name and the interest object. The origin node and the intermidiate which forward the object message from the destination to the origin stored that object in its cache.
The aplication starts by compiling it with the make command in the src folder. The next setp is to run the ndn executable as
./ndn IP TCP
where the IP TCP are the local IP and port of each node. To create a network use the command join only without the fouth and fifth arguments, and to join a node to a speacific node (which are already in a network) use all 5 arguments:
join <key_of_the_network> <name_of_the_node> <IP_of_the_neighbour> <PORT_of_the_neighbour>
After a node is in the network the following User Interaface is shown with the available commands:
