 terms of the large variety of players represented in the Internet space. It is also important to keep in mind that similarly to the PSTN, the Internet was not originally structured for what we're asking it to do now. Initially, the Internet was designed to support data communications-bursty, low-speed text data traffic. It was structured to accommodate longer hold times while still facilitating low data volumes, in a cost-effective manner. (With the packet-switching technique, through statistical multiplexing, long hold times do not negatively affect the cost structure because users are sharing the channel with other users.) The capacities of the links initially dedicated to the Internet were nar- rowband: 56Kbps or 64Kbps. The worldwide infrastructure depended on the use of packet switches (i.e., routers), servers (i.e., repositories for the information), and clients (i.e., the user interfaces into the repositories). The Internet was composed of a variety of networks, including both LANs and WANs, with internetworking equipment such as routers and switches designed for interconnection of disparate networks. The Internet relied on TCP/IP to move messages between different sub- networks, and it was not traditionally associated with strong and well-developed operational support systems, unlike the PSTN, where billing, provisioning, and network management systems are quite extensive, even if they are not integrated. The traditional Internet relied on the PSTN for subscriber access to the Inter- net. So the physical framework, the roadways over which a package travels on what we know as the Internet, is the same type of physical infrastructure as the PSTN: It uses the same types of communications, links, and capacities. In order for users to actually access this public data network, they had to rely on the PSTN. Two types of access were facilitated: dialup for consumers and small businesses (i.e., the range of analog modems, Narrowband ISDN) and dedicated access in the form The Organization of the Internet of leased
