Forward digisign ssn

last section in chapter four generalized forwarding and sdn so in these sdn routers okay the way we're doing forwarding is actually different from the traditional one therefore we call it the generalized forwarding in traditional routines you still recall in the data plane when packet arrives now we look at the destination ip address and we try to match destination ip address to the prefix entries in the forwarding table now if we match one what we essentially do is to forward the packet to the link interface indicated in the entry okay so in the traditional forwarding yeah what we're doing in terms of matching very specific the destination address what we're doing as an action is simply to forward the packet further putting sdn values in theta plane the matching and actions are now a lot more general this is the architecture of the modern routing or sdn based routing now the separation of data plane and control plane this part is actually very similar to the traditional routing now if you recall the overview of chapters 4 you should recognizing sdn the control plane look very different instead of having routing algorithms running on each individual routers we now run the routing algorithm centrally on one or maybe a couple powerful machines and these machines could be slightly far away from the routers in network now what's a bit similar though between sdn routing in the traditional routing is this after route computation we generate tables like this okay this is similar to a traditional routing line in the control plane of the traditional routing routing algorithm finish computation generates forwarding table and we install forwarding table to the data plane of the traditional router now in sdn tables are generated as well from the routing algorithm computation and we also install these tables to the data plane of the sdn routers you see the control plane to data plane connection there between sdn and traditional routing very similar the only slight difference is this in traditional routing we call these the forwarding tables but against the end we call them the flow tables okay so each router there will be installed with these flow tables to handle packets coming in and so on flow table if we zoom in it looks more like this in sdn in traditional forwarding we have what prefix the first column and the link interface the second column the actions being taken is very simple matching prefix and then four to a linked interface so what we're doing is always forwarding into traditional graphing but in sdn these actions could be more general okay not just forwarding so calling it a forwarding table is a bit awkward so instead in scn we call it the flow table instead and by flow sdn is actually referring to each of these entries each of these rows in the table that is also saying if packets coming into this router okay i'll wear...
