A fiber channel storage area network (SAN) provides virtualized storage space for a number of servers to a number of virtual disks implemented on various virtual redundant array of inexpensive disks (RAID) devices striped across a plurality of physical disk drives. The SAN includes plural controllers and communication paths to allow for fail-safe and fail-over operation. The plural controllers can be loosely-coupled to provide n-way redundancy and have more than one independent channel for communicating with one another. In the event of a failure involving a controller or controller interface, the virtual disks that are accessed via the affected interfaces are re-mapped to another interface in order to continue to provide high data availability. In particular, deadman timers, heartbeat signals internal to each controller, and heartbeat signals between different controllers are used to detect controllers that are no longer communicating with other controllers in order to identify those controllers which are failing or have failed.

The present application is directed towards systems and methods for systems and methods for handling real-time streaming protocol sessions by an intermediary multi-core system. When a multi-core intermediary receives a setup request for a real-time streaming protocol session, the intermediary processes and forwards the request to a server providing the streaming media. The server sets up an RTSP session and transmits a session identification to the multi-core intermediary. A core of the intermediary receives the transmitted session identification and determines an owner core of the session, based on a hash of the session identification. The core transmits the session information to the determined owner core, which selects two consecutive ports on which to establish listening services. The owner core then notifies all other cores to establish listening services on the same consecutive ports, such that any core that receives an RTSP control message from a client can handle it properly.

The parallel detecting spectroscopic ellipsometer / polarimeter sensor has no moving parts and operates in real-time for in-situ monitoring of the thin film surface properties of a sample within a processing chamber. It includes a multi-spectral source of radiation for producing a collimated beam of radiation directed towards the surface of the sample through a polarizer. The thus polarized collimated beam of radiation impacts and is reflected from the surface of the sample, thereby changing its polarization state due to the intrinsic material properties of the sample. The light reflected from the sample is separated into four separate polarized filtered beams, each having individual spectral intensities. Data about said four individual spectral intensities is collected within the processing chamber, and is transmitted into one or more spectrometers. The data of all four individual spectral intensities is then analyzed using transformation algorithms, in real-time.

The method provides a new fluid simulation technique that significantly reduces the non-physical dissipation of velocity using particles and derivative information. In solving the conventional Navier-Stokes equations, the method replace the advection part with a particle simulation. When swapping between the grid-based and particle-based simulators, the physical quantities such as the level set and velocity must be converted. A novel dissipation-suppressing conversion procedure that utilizes the derivative information stored in the particles as well as in the grid points is developed. Through several experiments, the proposed technique can reproduce the detailed movements of high-Reynolds-number fluids, such as droplets / bubbles, thin water sheets, and whirlpools. The increased accuracy in the advection, which forms the basis of the proposed technique, can also be used to produce better results in larger scale fluid simulations.

A policy enforcement point (PEP) attaches to the edge of a packet-switched network to manage loading when the network nears or exceeds its capacity due to changes in the network, e.g., component failures or incremental growth. Autonomous PEP's at the network's edges provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. Changes become necessary when a network event results in a loss of resilient bandwidth that effects the traffic class under admission control. Or, when an unexpected surge in traffic exceeds the PEP's reserved resources to a particular destination. The resources available across the network are recalculated for minimizing impact on existing sessions or calls, and it informs the PEP's of the new resources available. If the new maximum exceeds the current utilization to that destination, the PEP invokes a local priority drop mechanism to back off the traffic until it is under the new limit. A media gateway handling voice calls can keep all emergency calls up, and then invoke a local algorithm, such as random drop, for the remaining calls until calls to the constrained destination are under the new limit. In the second case, where there is an unexpected surge in demand, the PEP can request from the bandwidth manager additional resources to a particular destination.

Gate switches can switch an amount of attenuation, and are set in a distributed manner on distribution lines and a trunk on subscribers' house side in a CATV transmission path having a tree structure with an optical node that follows a headend being taken as a starting point. An upstream-transmission-quality monitoring unit monitors an S / N ratio of an upstream signal obtained from an upstream port having the headend connected thereto to detect a decrease in upstream transmission quality based on a degree of decrease and a continuation state of an S / N ratio. When the upstream-transmission-quality monitoring unit detects a decrease in upstream transmission quality, a noise-generation-source searching unit performs a sequential switching control over the amount of attenuation at the gate switches provided on the CATV transmission path from upstream to downstream to search for a source of generation of upstream ingress noise.

A data processing apparatus has address translation circuitry which is responsive to an access request specifying a virtual address, to perform a multi-stage address translation process to produce, via at least one intermediate address, a physical address in memory corresponding to the virtual address. The address translation circuitry references a storage unit, with each entry of the storage unit storing address translation information for one or more virtual addresses. Each entry has a field indicating whether the address translation information is consolidated address translation information or partial address translation information. If when processing an access request, it is determined that the relevant entry in the storage unit provides consolidated address translation information, the address translation circuitry produces a physical address directly from the consolidated address translation information. If on the other hand the relevant entry stores partial address translation information, the address translation circuitry produces an intermediate address from the partial address translation information and then performs the remainder of the multi-stage address translation process. Such an approach provides the performance benefits associated with a consolidated entry mechanism within the storage unit, whilst also allowing certain problem cases to be handled correctly and in an efficient manner.
