the ability of individual network devices to quickly detect failures and reroute traffic to an alternate path. This detection is now typically accomplished via hardware detection mechanisms. However, the signals from these mechanisms are not always conveyed directly to the upper protocol layers. When the hardware mechanisms do not exist (eg: Ethernet) or when the signaling does not reach the upper protocol layers, the protocols must rely on their much slower strategies to detect failures. The detection

many examples, an area particularly demonstrating this inequality among classes, is exclusionary zoning. These local laws have been seen to detain lower-income individuals from residing in certain communities by mandating specifications on lot sizes, types of housing, and the number of buildings and occupants allowed. Consequently these factors trigger an increase in community housing costs, and thus drive away lower-income individuals. In the past few decades however, states’ tolerance for exclusionary

NO. 3, MARCH 2000 535 Performance Analysis of the IEEE 802.11 Distributed Coordination Function Giuseppe Bianchi Abstract—Recently, the IEEE has standardized the 802.11 protocol for Wireless Local Area Networks. The primary medium access control (MAC) technique of 802.11 is called distributed coordination function (DCF). DCF is a carrier sense multiple access with collision avoidance (CSMA/CA) scheme with binary slotted exponential backoff. This paper provides a simple, but nevertheless extremely
