Abstract
The present invention proposes a measurement-based connection admission control device for a packet data network, comprising at least one measurement module adapted to measure packet data traffic in said packet data network and to output corresponding measurement results; at least one estimation module adapted to perform an estimation to obtain an estimated maximal rate envelope of traffic based on said measurement results, and an admission control module adapted to admit a requested new connection in said packet data network based on the estimated maximal rate envelope of traffic.
Claims24
A measurement-based connection admission control device for a packet data network, comprising
- at least one measurement module to measure packet data traffic in said packet data network and to output corresponding measurement results, said measurement module comprises counting means which measure the packet data traffic on a per packet basis by counting data packets;
- at least one estimation module to perform an estimation to obtain an estimated maximal rate envelope of traffic based on said measurement results, and
- an admission control module to admit a requested new connection in said packet data network based on the estimated maximal rate envelope of traffic,
- wherein said measurement result interface further comprises a measurement result ready indicator adapted to be set by said measurement module and to be read by said at least one estimation module, and wherein said at least one estimation module copies results indicated to be ready by said ready indicator from said a commonly used memory area for being processed by said estimation module.
A measurement-based connection admission control device for a packet data network, comprising
- at least one measurement module to measure packet data traffic in said packet data network and to output corresponding measurement results, said measurement module comprises counting means which measure the packet data traffic on a per packet basis by counting data packets;
- at least one estimation module to perform an estimation to obtain an estimated maximal rate envelope of traffic based on said measurement results, and
- an admission control module to admit a requested new connection in said packet data network based on the estimated maximal rate envelope of traffic, wherein a reading operation from said counting means and an update operation of previously measured results is prioritized, so that stability of the device under processor overload situations is achieved.
A method for admitting a requested new connection in a packet data network, the method comprising:
- measuring packet data traffic in a packet data network on a per packet basis by counting data packets;
- providing an indication that measurement results are ready;
- copying measurement results from a commonly used memory area when the measurement results are indicated to be ready;
- performing an estimation to obtain an estimated maximal rate envelope of traffic based on the measurement results;
- and
- admitting a requested new connection in the packet data network based on the estimated maximal rate envelope of traffic.
A method for controlling a measurement-based connection for a packet data network, the method comprising:
- measuring packet data traffic in a packet data network on a per packet basis by counting data packets;
- performing an estimation to obtain an estimated maximal rate envelope of traffic based on the measurement results;
- admitting a requested new connection in the packet data network based on the estimated maximal rate envelope of traffic;
- and
- prioritizing a reading operation in counting data packets and an updating operation of previously measured results.
