Look at BBs - don't care what happens within a domain, only between domains. Requests are aggregated. SLSs between domains, allocated in chunks of bandwidth. An individual BB will send changes to the other BBs, will query its local network, will have policy and management interfaces etc. For all of these, see the drafts.

Can script essentially any kind of queuing discipline. In April, will have an overlay network for several tests, including diffserv and multicast. More efficient mechanisms. IP security issues - mark before encrypting. Need diffserv on servers.
