Hi, I am working on a application which is meant for Delay Tolerant Network. I want to emulate the opportunistic link availability for the data sending nodes using dummyNet . One scenario, suppose from source node to destination node let's say a data link is available at around 9 a.m. morning and the latency of the link from source node to destination node is 1hr. So if a request for upload comes around 8 a.m. at the sending node then the data should start reaching to the destination node after 10 a.m. as the link between the nodes comes at 9 and the latency is 1 hr so delivery time at the destination node(9 a.m. +1hr. = 10.am.). In other words sending node should hold the data in its buffer till 10 a.m as the nodes are actually in my 100 Mbps LAN so for emulating this the sender must start sending the data after 10 a.m.
Can the buffer holds such large amount of data e.g. 500 MB for an hour. Or I have to modify the buffer size if yes, to which file i have to modify and then build dummynet. Or simply writing a batch scripts is fine for this. Please let me know.
