Pricing and managing SLAs. In this section we discuss the basic components of our pric- ing and management scheme, namely the e ective band- width bound that we use as a proxy for resource usage (Section 3.1) and its fairness (Section 3.4), the information posted by the network, and the pricing and management of SLAs (Section 3.2), and the user selection of tra c con- tract parameters (Section 3.3). We assume that the user's tra c contract x includes a peak rate h and a token bucket ( ; ), where is the token rate and is the bucket depth.
