“…For instance, operating in a different country would merely require downloading from a different website or using a new smart card. 5 Avoiding the creation of m n problems has long been a hallmark of good communications design (see [19]). The need for machine-understandable policies leads us to the problem of developing a language for expressing policies.…”

We consider the concept of opportunistic spectrum access (OSA)whereby radios identify unused portions of licensed spectrum, and utilize that spectrum without adverse impact on the primary licensees. OSA allows both dramatically higher spectrum utilization and near-zero deployment time, with an obvious and significant impact on both civilian and military communications. We discuss two broad classes of challenges to OSA: spectrum agility, which involves wideband sensing, opportunity identification, coordination and use; and policy agility, which enables regulatory policies to be applied dynamically using machine understandable policies. Focusing on spectrum agility, we present an architecture based on an OSA adaptation layer. We describe protocols for OSA, including a hole information protocol, idle channel selection and use, and an access protocol for the coordination channel. We present a simulation study, discuss insights, and show that even a simple protocol for opportunistic spectrum allocation can provide an order-of-magnitude performance improvement in throughput over a legacy system.

“…(That is, given an abstract enough interface--in the spirit of the Principle of Layering--a Host could, for example, go from doing TCP as its "Host-Host" protocol to, say, ECMA Class 4 as its "Transport" protocol without taking any particular cognizance of the change, however unattractive such a change would be to advocates of the APRANET Reference Model such as the author. See [3] for more on the implied "Reference Model" issues.) Finally, although a few rather specialized points could also be adduced, it should be noted that for network security architectures which are predicated on the ability to control all means of egress from and ingress to "the net", uniform use of OPEs is clearly desirable.…”
