[ndnSIM] Guidance for creating a new forwarding strategy

[Spyridon (Spyros) Mastorakis]

Hi Igor,

one way you could do that is to create a separate application (and install it on every node), which will get the info that you are interested in from NFD and advertise it to the other nodes. This app will also receive advertisements from others and send the required info to the modules that you want.

Hope that this helps,

Basically, the I'd use the number of replacements of the available policies (LRU, LFU, priority FIFO) to be used for forwarding interests. My intention is to create a new field in Interest packet set to 0 in the consumer node. the forwarding strategy would choose the next hop based on the number of content replacements of the adjacency nodes. So, it would be necessary to get this 'information  from next hop nodes  and store these values  in the faces attached  to them, so that the node handling the interest compare the current value in interest packet to the values of the faces. The strategy would send the packet to the face with the highest value.

My problem is regarded to which part of nfd I can make nodes advertise their replacement rates to their nodes, like the control messages of RIB manager do. I thought about using the variable cost used by the available strategies just to receive the replacement value and use as a cost.
