Nodal delay dnodal= dproc+dqueue+dtrans+dprop dproc = processingdelay dependes on time checking error, packet forwarding algorithem. dqueue = queuingdelay depends on congestion and packet on thelink. dtrans = transmissiondelay = L/R, significant for low-speedlinks dprop = propagationdelay The propagation speed depends on the physical medium of the link (that is, fibre optics, twisted-pair copper wire, and so on = d/s 6
