For example: - DNS: the name is mapped to an IP address - early binding to a location. - Magnet links, if I understand correctly: like DNS, but with just in time binding to where they direct you. - Directors of various sorts: the IP address is essentially virtualized, referring to one of several possible servers. Early binding to the server group, late binding to the actual server. - Layers 4 and above deal only with a "service id". An IP option is inserted in the packets, to be read by special middleboxes that guide the packet in the right direction (how they determine the right direction, and cache such information, is orthogonal) - medium to late binding. - Layers 4 and above deal only with a service id. A shim below Layer 4 maps the service id to an IP address of the next smart middlebox. Late binding. - IP addresses are eliminated entirely, and packets are routed only on "interest" names. There is never a binding to an IP address. It seems to me that people's preferences for different layers and binding times depend on the time frame of deployment they are interested in.
