Purpose: The patent relates to a method for making admission control, and to a network node comprising software for performing admission control. According to the supplied text, configuring an asynchronous network for multiple services—some offering guarantees or assurances on forwarding quality—requires dividing forwarding resources (buffer capacity and forwarding capacity) into different classes; admission to classes carrying guaranteed/assured traffic must then be controlled (admission control). Admission control can also maintain guarantees or assurances in single-service networks.

Plain-language scope: The disclosed mechanism concerns controlling whether traffic is admitted to a resource class so that forwarding-quality guarantees or assurances are upheld. Admission control may be distributed across network nodes or centralized in servers/dedicated computers—all referred to as a "node." It may be invoked by, e.g., a signalling protocol; its location does not directly affect the forwarding quality guaranteed or assured, though it may affect scalability and performance.

The excerpt discusses traffic characteristics relevant to admission decisions, including peak-rate (maximum rate an ADF can send in a given time interval) and average-rate (typically calculated over a long interval). It notes that where the sum of peak-rates for ADFs sharing a common link exceeds the link's forwarding capacity or the allocated portion, while the sum of average rates does not, statistical properties matter. Such properties may be known beforehand (e.g., from a speech codec definition) or estimated through measurements—measurement being preferable for unpredictable ADFs (e.g., video conferencing). The excerpt then truncates ("Another approach to offer assurances...").

Classifications: H04L47/00, H04L47/70, H04L47/82, H04L47/822, among others.

What the excerpt does not establish: The full claim language, the complete detailed description, and the specific admission-control algorithms or thresholds are not reproduced; the excerpt is explicitly truncated. It also does not establish validity, enforceability, or the accuracy of the listed assignee/status, which the source itself notes are assumptions.
