20100138614Compression Status Bit Cache And Backing Store - One embodiment of the present invention sets forth a technique for increasing available storage space within compressed blocks of memory attached to data processing chips, without requiring a proportional increase in on-chip compression status bits. A compression status bit cache provides on-chip availability of compression status bits used to determine how many bits are needed to access a potentially compressed block of memory. A backing store residing in a reserved region of attached memory provides storage for a complete set of compression status bits used to represent compression status of an arbitrarily large number of blocks residing in attached memory. Physical address remapping (“swizzling”) used to distribute memory access patterns over a plurality of physical memory devices is partially replicated by the compression status bit cache to efficiently integrate allocation and access of the backing store data with other user data.06-03-2010
20110087840EFFICIENT LINE AND PAGE ORGANIZATION FOR COMPRESSION STATUS BIT CACHING - One embodiment of the present invention sets forth a technique for performing a memory access request to compressed data within a virtually mapped memory system comprising an arbitrary number of partitions. A virtual address is mapped to a linear physical address, specified by a page table entry (PTE). The PTE is configured to store compression attributes, which are used to locate compression status for a corresponding physical memory page within a compression status bit cache. The compression status bit cache operates in conjunction with a compression status bit backing store. If compression status is available from the compression status bit cache, then the memory access request proceeds using the compression status. If the compression status bit cache misses, then the miss triggers a fill operation from the backing store. After the fill completes, memory access proceeds using the newly filled compression status information.04-14-2011

20080212475Method and Device for Management of Flow in a Packet-Telecommunication Network - This A flow management method includes a step (E09-04-2008
20100046529METHOD OF CONFIGURING THE QUALITY-OF-SERVICE PROFILE OF A GIVEN STREAM AT AN ACCESS NODE OF A PACKET COMMUNICATIONS NETWORK - A method is provided for configuring the service quality profile of a given flow at the access node of a packet communication network to which is connected to the gateway of a receiving user of the flow. The method includes a step where the gateway determines on its own a service quality profile to be associated with the flow, that is triggered upon reception of a packet from the access node, and a step where the service quality profile thus determined is sent to the access node. The profile is used by the access node for transmitting packets intended for the gateway and belonging to the flow in question.02-25-2010
20100278053Method for Organizing Packets Belonging to Streams, and Associated Equipment - The inventive method consists in determining a flow (F) to which belongs each new incoming packet (P), when said flow (F) is on a list of active flows, in introducing said packet into a fair share scheduling mechanism (11-04-2010
20110038383A TECHNIQUE FOR TRANSMISSION BY A NODE OF A COMMUNICATIONS NETWORK - A transmission method is used by a node of a communications network, wherein nodes communicate with one another via a carrier-sense multiple-access channel, said method comprising a step of sending a signal at a given transmit power and a given data rate to a receiver node over the channel, and wherein the transmit power of the sent signal assumes successively a first power value during a first time period and then a second power value during a second time period, the two power values being different and one of them being equal to the given power, the first time period representing the given power and the second time period representing the data rate. The invention also relates to a method of receiving a signal sent by the transmission method enabling the transmit power and the data rate used by the sender node to be deduced from the received signal.02-17-2011
20110122791TECHNIQUE FOR COMMUNICATION BETWEEN A PLURALITY OF NODES - A method is provided for communication between a plurality nodes organized as a ring provided with transmission resources at least one of which is a control resource dedicated to transmitting control information and associated with at least one transmission resource, said method comprising the following step executed by a node of the ring: a step of receiving information relating to a reservation of a transmission window of the transmission resource received over the associated control resource. The method further comprises, if the transmission window is reserved by another node of the ring, steps of: comparing the respective volumes of reservations of resources of the ring made by the node in question and by the other node during a reference period; and pre-empting said reservation of the transmission window as a function of the result of the comparison step.05-26-2011
