A class of discrete plants controlled by a switching adaptive strategy is considered, and lp bounds, 1 ≤ p ≤ ∞, are obtained for the closed loop gain relating input and output disturbances to internal signals.

It is desirable that the traffic-control policy at a network node depends only on the external traffic loads on the input and output links, but not on the detailed addressing or distribution of packets from inputs to outputs. It should be possible to guarantee the gradeof-service of an input-output connection by controlling the aggregate loads on the input and output. Switch nodes in which such...
