Abstract
A packet network employing a reservation-based protocol system includes routers having processing sections that schedule message processing of the protocol's control messages adaptively based on link utilization. A scheduler of the processing section employs a round-robin scheduling with adaptive weight assignment to allocate processing capacity for control messages. For the RSVP protocol, for example, messages are grouped in classes, and link utilization of the packet flows for each message class is monitored. Weights corresponding to a portion of the processing section's processing capacity are allocated to each message class. The weights are defined based on link utilization for the message class and average message queue length. For processing sections monitoring multiple links, weights are further defined for super-classes based on overall link utilization. Weights may change as link utilization and average message size changes. With defined weights adaptively defined, the processing section then processes each message class in a cyclic, 'round-robin' fashion.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
