provision of more units for monitoring or policing parameters of traffic flow of cells in telecommunications systems operating according to the technique of atm, and method

摘要

arrangement and method for monitoring parameters of traffic flow of atm cells according to the principle of the so-called "leaky bucket" in a termination (et) comprising a central unitthe preparation and translation of the headers (htu).are provided for different units of monitoring or policing (pu1, pu2, pu3, pu4), for the control of the peak bit rate (pr) and medium (rm).by discriminating between the cells belonging to the flow to a high priority (clp = 0) and those belonging to the flow with low priority (clp = 1).the units are activated in parallel by the processing units and translation (htu) and linked to a combinational circuit (rc).in case of violation of the negotiated parameters, the cell priority can be downgraded and treated like any other lower priority, or may be discarded.the update is performed in the unit in the next cycle of monitoring of the cell on the same connection (fig. 5).
