POLICING DEVICE AND POLICING METHOD USING SAME

摘要

Policing device and policing method using same The proposed policing device includes selection means (SEL) to form a composite information stream which consists of the information units of a plurality of individual information streams. In this way the policing device can for instance police more efficiently information streams carrying bursty traffic. Indeed, a composite stream, formed from a plurality of such individual information streams, has, due to the statistical properties of such information streams, a less bursty information rate which can be characterized much more efficiently. Hence also the policing algorithm (PA1;..;PAN) used to police the composite stream will be much less complicated than the policing algorithm needed to police the separate streams carrying bursty traffic. Moreover can such a policing device inherently detect correlation between the information rates of the streams grouped together in such a composite stream. The detection of such correlation is very advantageous in an ATM network which presupposes that these information rates are uncorrelated.
