If you are using standby redo logs on the standby and LGWR (versus ARCH) as the method in your dest_2 parameter on the primary, you aren't shipping the entire log (at one time), but instructing LGWR to propagate its redo I/O over the network as it is generated. I'm not sure that helps you, but if you are concerned about network bursts at log switches ("rather then ship the physical 50mb log"), that should help.
