Abstract: A method and system for reducing the signal interference effects of metal doors in a metal detection system. The system includes a transmitter operable to transmit an interrogation signal that is used to detect transitory metal objects within the detection region, a receiver operable to receive instantaneous signals that represent electromagnetic field disturbances during operation of the metal detection system and include electromagnetic field disturbances attributed to the movement of metal doors. The system also includes a metal detection module that determines a resulting waveform representing the difference between the instantaneous signals received during operation of the metal detection system and a recorded pattern of signals representing electromagnetic field disturbances caused by a pattern of movement of the metal doors in the detection region when a transitory metallic object is not present.

Abstract: An improved packet handler for VoIP cable modems and other high-speed digital devices includes a direct communication link via hardware among internal processing components. Incoming and outgoing digital information packets are filtered into MAC packets, voice PDU packets, and non-voice PDU packets, such that priority can be given to relaying voice packets and minimizing potential voice delay within the cable network. Hardware components, including specialized logic circuitry, modify voice packets to an appropriate signal form for subsequent signal processing or signal transmission. Proprietary bus communication protocols can also be provided to facilitate relay of packets between a central processing unit (CPU) and a digital signal processor (DSP) within a VoIP cable modem. Line cards including subscriber line interface circuit (SLIC) and subscriber line audio processing circuit (SLAC) components provide analog-to-digital (A/D) and digital-to-analog (D/A) conversion functionality.

Abstract: A method and system provide in-band protection switch signaling in a communication system arranged as a point-to-multipoint tree. The point-to-multipoint tree includes a root node communicatively coupled to a plurality of leaf nodes through both a working link and a protection link. Data is transferred through a current link of the point-to-multipoint tree. The current link is either the working link or the protection link. A fault is detected in the current link in the point-to-multipoint tree. Each leaf node in the point-to-multipoint tree is notified of the fault using the current link. Upon receiving the notification, the root node and each leaf node switch to the other link of the working link and the protection link.

Abstract: An architecture that enables distributed storage capacity to be shared as though accesses were being made to a Fiber Channel Switch is described. The distributed capacity may include Fiber Channel devices and thus a method for addressing Fiber Channel devices coupled in a resilient ring has been provided. Expected Fiber Channel behavior and reliability are attained in the architecture of this invention through the application of bandwidth provisioning and extended reach mechanisms at each node in the ring. The bandwidth provisioning mechanisms ensure that access is provided to the communication links of the ring for each node according to a defined bandwidth distribution. The extended reach mechanisms of the invention ensure that the standard Fiber Channel packet delivery assumptions are satisfied. The solution exploits native ring characteristics to deliver customer separation and management of the resulting storage network.

Abstract: Frame contained destination information may be used by a switch to identify an appropriate output port for a given frame without performing a table access operation. This reduces the processing requirements of the switch to enable the switch to handle frames more efficiently. The frame contained destination information may be contained in the frame's local destination MAC addresses (DA) such that a portion of the DA directly indicates, for each switch that handles the frame, an output port for that switch. Different portions of the DA may be used by different switches, depending on where they are in the network hierarchy. Large switches may also use sub-fields within their allocated portion in the DA to identify internal switching components. A location resolution server may be provided to store and distribute IP and MAC addresses and respond to local ARP requests on the local domain.

Abstract: Described is a system and method of protection switching in an Ethernet network. First and second point-to-point Ethernet links are established to data equipment. Identical streams of Ethernet traffic are received at a first Ethernet port and at a second Ethernet port. The stream of Ethernet traffic being received at the first Ethernet port is transmitted to the data equipment over the first point-to-point Ethernet link, while the second Ethernet port is prevented from transmitting the stream of Ethernet traffic received at the second Ethernet port. During a protection switch, transmission of Ethernet traffic ceases over the first point-to-point Ethernet link, and commences over the second point-to-point Ethernet link, the second Ethernet port transmitting the stream of Ethernet traffic being received at the second Ethernet port to the data equipment.

Abstract: It is often required to send a plurality of streams of data in parallel between two network nodes in a synchronous transmission network and also to maintain a particular alignment between those streams of data. This is particularly required when the streams of data are to be transmitted over a wide area network, for example, for data mirroring applications. Virtual concatenation is used for each of the individual data streams as known in the art and in addition, the individual virtual concatenation processes are synchronized or co-ordinated. At a destination node it is then possible to realign the individual data streams with respect to one another.
