Abstract: An emergency alert system for alerting DSL subscribers of imminent perils includes an alert server connected over a direct link to an edge node of a metro network for receiving an event notification, configuring from an event notification a highest priority alert message, and broadcasting the alert message to subscriber terminals over the metro network. An Add-Drop Multiplexer (ADM) multiplexes the alert traffic with the regular traffic onto the direct link, and the multiplexed traffic reaches the edge node of the metro network, which is configured with a high priority policy. The edge node discards the lower priority traffic in the presence of the alert traffic and an applet installed on the subscriber terminal accepts and displays the alert message in a browser or a media player.

Depending upon which geographic zone the remote terminal is in or nearby, power level, and time period of communication vary.
Abstract: A method for analyzing the mitochondrial function of a subject involves: conducting a first test wherein the average oxygen consumption of the subject during exercise is measured while the subject is breathing air having a first oxygen concentration, preferably room air having a concentration of 20-21% by weight; conducting a second test wherein the average oxygen consumption of the subject during exercise is measured while the subject is breathing air having a second oxygen concentration, preferably air having an oxygen concentration of 30-33% by weight; measuring first and second energy quotients obtained from the first and second tests, respectively; and then using the energy quotients to calculate the subject's Mitochondrial Factor. The Mitochondrial Factor is directly proportional to the subject's mitochondrial efficiency and function. If conducted periodically, the method can be used to determine whether the subject's mitochondrial efficiency is increasing or decreasing over time.

Abstract: A method and system for filtering malicious packets received at the edge of a service provider (SP) domain is provided. A protocol aware border element identifies the protocol used by any ingress packet, and then determines which domain-specific information is used in the application payload of the packet to form the source identity. If this packet pretends to come from the SP domain, and no domain entity is allowed to roam, the packet is identified as illegitimate and is subjected to a given security policy. The border element also identifies as legitimate the SP domain entities that are allowed to roam, and legitimate sources outside said SP domain that communicates customary with entities in the SP domain.
Abstract: The invention enables an LSP or embedded LSPs to be mapped directly to an SPVC and carried over the ATM network. A unidirectional SPVC is established by associating it to a particular ingress LSP at the SPVC source endpoint on a multi-service switch, and to an egress LSP on the SPVC destination endpoint on another multi-service switch. The information necessary to establish the SPVC is appended in the SPVC setup message and includes LSP specific information such as the far end router ID and LSP label information, be it transport label or the full label stack. The information in the modified setup message is then used by the destination endpoint to find and connect the SPVC to the correct LSP. Incoming traffic from the LSP is switched to the SPVC at the source endpoint. The SPVC carries this traffic through the ATM network, and then the traffic is switched to the egress LSP when it emerges from the ATM network at the destination endpoint.
Abstract: The PIP system enables display of a mosaic of favorite channels in a Picture-in-Picture (PIP) format to a subscriber terminal. Picture-in-Picture support is efficiently provided by sending only I-Frames of the secondary video channel to the end-user. That is, any unnecessary packets (null, B-P frames, audio, etc.) in the secondary video channel are stripped away. This method uses very little bandwidth and is STB agnostic.

Abstract: In a system that provides decoding of A/V streams, this invention reduces switching delays between different streams by modifying the Program Identification (PID) values of the Audio and Video data to respective PID values that are already known by the decoder. This technique allows the decoder to stay in a run state when switching between A/V streams, thereby reducing channel change times.

Abstract: At telecommunications switches and routers, RED (random early packet discard) uses the queue depth to determine whether to keep or discard each packet as it arrives at a queue. This is done by determining a discard probability (P), which is dependent on the average depth of the queue, and comparing the discard probability to a random number. One way of performing the invention uses the summed discard probabilities, instead of counting the number of packets (count) and multiplying that by the current discard probability, as in the prior art. The resulting sum is compared to the random number for discard operation. The disclosure further describes a more accurate way of calculating average depth of a queue, especially when the queue encounters periods of idleness.
Abstract: A method of collecting consistent flow statistics through multiple congestion points within a multi-service switch/router is enabled by computing a payload length of each traffic unit received from a fabric of the switch/router. A PHY-level header containing the payload length, a class of service and a service ID is appended to the switch-internal encapsulated payload. Information associated with the PHY-level header is used at physical level congestion points to collect consistent flow statistics.

Abstract: An access system, such as a DSL (Digital Subscriber Line), includes a multiplexer for connecting subscriber devices, such as telephones and/or IP terminals, to a subscriber line; and an access multiplexer for connecting subscriber lines to a backbone network. The access system may also include a gateway for connecting the backbone network to a first system. When the access system receives a voice call to a second system via the telephone system and the first system employs a voice coding method, the access system is arranged to negotiate with the second system a type of voice codec to be used in both the first and second system. The access systems is configured to transmit an encoded voice signal from the subscriber device or the multiplexer to the first system and to transmit an encoded voice signal from the first system to the subscriber device or the multiplexer.
Abstract: One or more content sequences are created from a store of video content, which could simply be broadcast content which has been captured and stored at a server within a network. The content sequences are generated according to the viewer's specified, or demonstrated, viewing preferences. The viewer preferences are captured form entry by the user themselves, or by observation of their viewing habits. Multiple ‘users’ per household and multiple content sequences per viewer are possible. A content sequences is then streamed to the viewer, and looks to him/her just like a TV channel: when one program ends, another starts automatically. It is also possible for a viewer to select an item within the content sequence using an interactive program controller.
Abstract: Symmetric Connection Detection (SCD) is a method of detecting when a connection has been fully established in a resource-constrained environment, and works in high-speed routers, at line speed. Many network monitoring applications are only interested in connections that become fully established, so other connection attempts, such as port scanning attempts, simply waste resources if not filtered. SCD filters out unsuccessful connection attempts using a simple combination of Bloom filters to track the state of connection establishment for every flow in the network. Unsuccessful flows can be filtered out to a very high degree of accuracy, depending on the size of the bloom filter and traffic rate. The SCD methodology can also easily be adapted to accomplish port scan detection, and to detect or filter other types of invalid TCP traffic.
