Abstract
To avoid lost packets that could otherwise occur were a round robin scheduling policy to be used to assign PPP packet fragments to multiple communication links, the links are assigned tokens based on their capacities, with a fragment being assigned to the link with the most tokens. When a fragment is scheduled to a link, the tokens of the link are decremented accordingly. The tokens are periodically refreshed.
