Internet Policy Going Forward : Does One Size Still Fit All?

Much of the current debate over Internet policy is framed by the belief that there has always been a single Internet that was open to everyone. Closer inspection reveals a number of important ways in which the architecture has deviated from this commitment. Providers frequently deploy Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV) over hybrid networks that reserve bandwidth or employ technologies such as MultiProtocol Label Switching (MPLS) that are not fully accessible to the public Internet. At the same time, the increasing value in variety and decreasing returns to scale is mitigating the value of being connected to a single network, and the growth of multihoming, in which subscribers maintain multiple connections, is contradicting the myth of the one screen that presumes that every connection must be everything to everyone. Finally, large customers who are unable to receive the services that they need use exit as an option by turning to private networking. These developments counsel against maintaining a one-size-fits-all approach to Internet policy that may not reflect current realities
