摘要： Example embodiments relate to selective invalidation of packet filtering cache results based on rule priority. In example embodiments, a network node determines whether a rule identifier included in a cache entry of a cache of results of a packet filtering rule set is of a higher priority than a highest priority rule corresponding to a rule set version identifier included in the cache entry. If so, the network node may apply an action included in the cache entry.

摘要： A network controls congestion by monitoring how well packets are actually being received at their respective dataflow destinations. The destination nodes are outfitted with a monitor that returns an acknowledgement (ACK) datapacket to the source node for each reception. The return ACK datapackets are marked according to whether congestion was encountered in the delivery to the destination. If so, a rate limiter at the source node is signaled to slow down the data injection rate. If not, the rate limiter is signaled to dial up the injection rate. Several dataflows can be independently and simultaneously controlled this way.

摘要： A method of detecting congestion in a communications network and a network switch are described. The method comprises identifying an output link of a network switch as a congested link on the basis of a packet in a queue of the network switch which is destined for the output link, where the output link has a predetermined state; and identifying a packet in a queue of the network switch as a packet generating congestion if the packet is destined for a congested link.

摘要： An embodiment of a method of virtualizing a counter in a computer system comprises a first step and iterative performance of second through fifth steps. In the first step, a virtual machine monitor programs a hardware event counter with an initial count for a profiling event for a virtual machine. In the second step, the virtual machine monitor saves a suspension count and disables the hardware event counter upon suspending operation of the virtual machine. In the third step, the virtual machine monitor programs the hardware event counter with the suspension count upon resuming the operation of the virtual machine. Upon receiving an interrupt from the hardware event counter that provides notification of reaching the initial count, the virtual machine monitor performs the fourth and fifth steps. In the fourth step, the virtual machine monitor saves a sample that comprises an event identifier and a code-in-execution indicator. In the fifth step, the virtual machine monitor reprograms the hardware event counter with the initial count.
