A method, programmed medium and system are provided in which system bus traffic is moderated with real-time data. The Operating System (OS) is enabled to get information from the firmware (FW) to determine if a resource threshold has been reached. This is accomplished by generating an interrupt to flag the OS when a bus request retry rate has reached a predetermined number. The system firmware plays an integral role in this mechanism, and should be interpreted as a general term which could also include a hypervisor technology. The system firmware will report the bus request retry rate to the operating system by way of, for example, a firmware-generated interrupt. The OS may have something similar to a kernel daemon/service running to intercept the interrupt notice.

If so, it will generate a system call that will moderate traffic with an operating system tunable. In one example, the number of simultaneous multithreading (SMT) threads per core will be reduced using a system call. This effectively throttles back the amount of logical threads per core and effectively alleviates the bus request saturation.

US07962434B2 Extended finite state automata and systems and methods for recognizing patterns in a data stream using extended finite state automata
Deterministic finite automata (DFAs) are popular solutions to deep packet inspection because they are fast and DFAs corresponding to multiple signatures are combinable into a single DFA. Combining such DFAs causes an explosive increase in memory usage. Extended finite automata (XFAs) are an alternative to DFAs that avoids state-space explosion problems. XFAs extend DFAs with a few bytes of “scratch memory” used to store bits and other data structures that record progress. Simple programs associated with automaton states and/or transitions manipulate this scratch memory. XFAs are deterministic in their operation, are equivalent to DFAs in expressiveness, and require no custom hardware support. Fully functional prototype XFA implementations show that, for most signature sets, XFAs are at least 10,000 times smaller than the DFA matching all signatures. XFAs are 10 times smaller and 5 times faster or 5 times smaller and 20 times faster than systems using multiple DFAs.

US07961647B2 Detecting interfering packet streams in packet networks
A method for estimating the network-layer topology of a telecommunications network is described. In particular, the illustrative embodiment of the present invention estimates the existence and connectivity of nodes in the topology based on the detection of network-wide end-to-end path intersections. This is based on the assumption that pairs of streams of packets that share a common node will interfere and that the interference can be detected in the received streams. In general, this interference is manifested as jitter. By transmitting streams on each pair of end-to-end paths in the network, and detecting interference (or a lack of interference) a matrix of path intersections for the network can be created. Using logic and supposition, the topology of the network can be estimated using the matrix of path intersections. Once the estimate of the topology is complete, the maintenance and operation of the network can proceed based on the topology.
