Method for upstream priority lookup at physical interface within a wireless device
First Claim
1. A method for determining a priority classification of a burst at a physical interface of a wireless communications device, comprising the steps of:
- detecting an identifier from the burst at the physical interface of a wireless device; and
matching said identifier to a priority indicator to determine the priority classification.

Abstract
A traffic prioritization system and method performs a coarse classification of upstream bursts at the physical interface of a wireless communications device. The wireless device monitors and controls communications with a plurality of remote wireless communications devices throughout a widely distributed network, including the Internet. The traffic prioritization system includes a burst receiver that receives and sends the upstream bursts to a classifier. At an appropriate time, the classifier receives the upstream bursts and queries a priority lookup table (LUT) to determine a priority classification. The priority classification is used to separate the bursts into two or more priority levels. The higher priority level is used to designate services having a low tolerance for delay, such as telephony. Upon classification, the upstream bursts are forwarded to one of several priority queues. Each priority queue corresponds to at least one priority level. The headend device services each priority queue such that the higher priority queues are serviced before the lower priority queues.

16. A method for determining a priority classification of a plurality of bursts at a physical interface to a central controller within a wireless network, comprising the steps of:
-
processing the plurality of bursts at the physical interface to detect an identifier from each burst; and
matching said identifier from each burst to a priority indicator, wherein said priority indicator represents one of two or more available priority levels. - View Dependent Claims (17, 18, 19, 20)
