Hi Richard,
I looked the repo; he's defined 3 classes: one for packets, one for nodes, and one for links. So yes, he instantiates links. Likely each node has a collection of links (each of which leads to another node in the network). The application is to simulate a network by modeling it in ST, so that means generating packets, each with a destination node (where nodes have addresses), and simulating how the packets flow through the network to get from their source nodes to their destination nodes.
I hadn't though about sending the blocks to the nodes via the packets, but that *is* a cool concept... And entirely do-able in Pharo. However, if the exercise is to make a simple network model that runs to simulate network operation, I doubt that's what they're looking for, though (since it's not what you typically do in a packet network). I think they just want you to model the packet-handling behavior, and that's what the block is for. (I may be wrong.)
Thanks, Ted. That makes sense. I agree the problem is almost certainly not about sending blocks. Silly of me, really. I didn't see anything in this thread that explained the block. I could imagine that a link object knows how to deliver a packet to the node and the node object knows how to receive the packet. (Or something like that)
