20090122698	VIRTUAL QUEUE - An apparatus comprising a virtual queue configured to virtually receive virtual data units as the data units are actually received by a real queue. In various embodiments, the virtual queue may include a committed token counter (CTC) configured to represent a number of bytes available to be allocated to a committed burst having a maximum size. In such an embodiment, the virtual queue may include an excess token counter (ETC) configured to represent a number of bytes available to be allocated to an excess burst having a maximum size. In one embodiment, a token counter incrementer configured to, as an exiting data unit virtually exits the virtual queue, increment either the committed token counter or the excess token counter. In various embodiments, the virtual queue may include a token counter decrementor configured to, as an entering data unit virtually enters the virtual queue, attempt to allocate the entering data unit to either the committed burst or the excess burst and decrement either the committed token counter or the excess token counter respectively. In some embodiments, the virtual queue may include a congestion indicator configured to categorize the entering data unit. In various embodiments, the virtual queue may be configured to provide congestion feedback information based, at least in part, upon the state of the CTC & ETC.	05-14-2009

20080219285	Multi-Channel Communications Protocol - There is a need to improve design of communications protocols in which two or more channels are provided and, optionally, in which collision avoidance is not available. An improved protocol is provided in which communications nodes pick a channel on which to transmit and collisions may occur where two nodes attempt to transmit on the same channel. The node currently occupying a channel is arranged to have a specified probability of holding onto that channel as compared to a newcomer. Other methods are described whereby a node is able to occupy more than one channel at the same time and whereby nodes each occupy approximately the same number of channels.	09-11-2008

20080270842	COMPUTER OPERATING SYSTEM HANDLING OF SEVERE HARDWARE ERRORS - A system and method is provided for handling severe hardware errors communicated to a computer operating system as an abort indication. The method includes classifying the type of abort into a memory-related error or non-memory-related error. For memory-related errors, a debug file is written that includes error source information for an affected process without accessing the affected process memory.	10-30-2008
