....are positive ones, bringing new features and new flexibility to the internet, there is no question that these changes require new functionality and result in added complexity. An alternative address assignment scheme is geographical addressing, such as exists in the global telephone network [14]. Because geographical addresses remove the dependency of address on provider, a subscriber can change providers or have multiple providers without changing addresses. 37 Bad Scaling Good Scaling Typical Operating Region Ideal Operating Region Good Paths Bad Paths Figure 3.5: ....

....of a packet (or, whatever writes the locator into the packet header) to control the path. A significant amount of attention has been paid to the locator in its scaling role, both in the research literature [67, 46, 62, 61, 103, 106] and in commonly used networks such as IP [87] and public voice [14] and data networks [15] Recently, some attention has been paid to the locator in its path control role, primarily in the context of the so called policy routing problem [11, 107, 36, 34, 35, 101] The latter function of the locator (path control) is important, and is treated later in this ....

....of the hierarchy are assigned according to the geographical location of the private network. In the latter approach, the top levels of the hierarchy are assigned according to the provider(s) that the private network connects to. International telephone numbers (E. 163) are assigned geographically [3]. X.121 (the numbering plan of X.25) is geographically assigned at the top, but has an element of provider orientation from the DNIC [4] The internet has historically been less regulated than either the global telephone network or X.25 networks. Thus, a pure provider orientation in the ....

....are positive ones, bringing new features and new flexibility to the internet, there is no question that these changes require new functionality and result in added complexity. An alternative address assignment scheme is that of geographical addresses, such as exists in the global telephone network [3]. Because geographical addresses remove the dependency of address on provider, a subscriber can change providers or have multiple providers without changing addresses. The use of geographical addresses, however, puts an additional burden on providers, in terms of how much routing information they ....
