摘要： A scalable Multimedia Network providing integrated networking of data, voice, video and image services over a variety of access facilities including metallic loops, fiber/coax or digital fiber is disclosed herein.The SMN establishes customer initiated switched virtual circuits for all traffic types and directs them to the appropriate backbone network. The SMN is based on a distributed switching platform that enables carriers to economically provide service to a small number of customers and add capacity incrementally as the customer base increases. The platform has a protocol adaptation capability which permits communications between customer premises equipment and potentially incompatible backbone networks or network servers.

摘要： A congestion relieving system in a communication system includes a local switch (62a) and a customer station including a network terminator (64a) connected to the local switch (62a) and plural data receiving/transmitting units (65) connected to the network terminator (64a) through buses (67D and 67U) conformable to a DQDB protocol. The local switch (62a) includes a congestion relieving signal generating unit for generating a congestion relieving signal when congestion is detected. The congestion relieving signal is inserted, as a request bit, into a request bit area in the cell having a format conformable to the DQDB protocol. The cell is then transmitted from the local switch (62a) through the network terminator (64a) to the data receiving/transmitting units (65), and each data receiving/transmitting unit (65), is restricted, under the DQDB protocol, to transmit data, when the data receiving/transmitting unit (65) receives the request bit.

摘要： A combination of two new access methods for ring and unidirectional bus networks supports high data rate integrated traffic. The first access method provides access for asynchronous traffic. When a node senses the channel idle, it can begin to transmit. When it senses an incoming signal, it must stop transmitting in order to avoid a collision. But unlike other access protocols which abort the transmission when a collision occurs or is imminent, the process truncates the message in a fashion such that it can be resumed later when the channel again is idle. The system is called Carrier Sensed Multiple Access-Ring Network (CSMA/RN). The second access method provides support for synchronous traffic. This method implements one or more circulating reservation packets which permit a node to have reserved space when the special packet returns. The media access system is called Circulating Reservation Packet (CRP) system. Both access protocols operate simultaneously on the network with minimal interference. The CRP system is preferably used with the CSMA/RN protocol but is applicable to other fixed length, non-corrupting, circulating network structures to enable the nodes in a network to reserve space for synchronous traffic and guaranteed access.
摘要翻译：环形和单向总线网络的两种新的访问方法的组合支持高数据速率集成流量。第一个访问方法提供异步流量的访问。当节点感知到信道空闲时，它可以开始传输。当它感测到一个进入的信号时，它必须停止传输，以避免碰撞。但是，与发生冲突或即将发生的中止传输的其他接入协议不同，该过程将以某种方式截断消息，以便在信道再次空闲时可以恢复该消息。该系统称为载波感应多址环网（CSMA / RN）。第二种访问方式提供对同步流量的支持。该方法实现一个或多个循环保留分组，当分组返回时，该分组允许节点具有保留空间。媒体接入系统称为循环预留分组（CRP）系统。两种接入协议在网络上同时工作，干扰最小。 CRP系统优选地与CSMA / RN协议一起使用，但是适用于其他固定长度的，不破坏的循环网络结构，以使得网络中的节点能够为同步业务保留空间并保证接入。

摘要： In a communication system comprising several nodes and a scheduler interconnected by a serial transmission medium, signalling information is transmitted by inserting it whenever required in the data stream in the form of basic data units (ADU). The scheduler inserts a request start and an end flag, and any node requiring allocation of a given type of service insert its request unit between the flags. Thus, the scheduler receives accumulated node-individual request information. The scheduler then sends a response comprising individual response units between two delimiting flags. Each node having made a request removes the respective individual response unit so that only the flags return to the scheduler. Special pipelined circuitry allows insertion and removel of the basic data units constituting the signalling information at very high speed without impeding the speed and timing of the passing data stream.

摘要： Bandwidth balancing is accomplished to DQDB networks that handle multi-priority traffic by causing each node to throttle its own rate of transmission in accordance with the priority of the data that the node transmits. In accordance with one approach, each node limits its throughput to the product of a bandwidth balancing factor (which is a fraction that varies according to the priority level of data) and the unused bus capacity. When parcels of different priorities are received within each node, the parcels are processed in priority order. In accordance with another approach, all active parcels within a node are handled concurrently and receive some bandwidth. The throughput of each parcel in a node is limited to the product of the bandwidth balancing factor and the unused bus capacity. In accordance with still another approach, each traffic parcel limits it throughput to the product of the bandwidth balancing and the bus capacity unused by parcels of equal or higher priority. This scheme allocates bandwidth first to the higher-priority parcels, then allocates the leftovers to the lower-priority parcels. Lower-priority parcels have no effect on the steady-state throughputs of higher-priority parcels.

摘要： A system and method for bandwidth management by controlling the bit rate of a signal stream in real time according to available link bandwidth. Applications include multiple-channel video data streams over a limited-bandwidth link such as a Digital Subscriber Line. A video signal is transrated at the head end to multiple streams having different bit rates, by a multirating device which sends the multiple streams over a network, along with metadata containing information about the data structure and parameters of the streams. At the network access edge, a demultirating device uses the metadata to select the stream with the highest video quality whose bit rate does not exceed the available bandwidth of the end-user's access link. This scheme provides multiple unicast signals to different end-users in place of a single multicast signal, supports multiple high-definition channels over a limited bandwidth link, and is compatible with standard encryption methods.

摘要： Novel tools and techniques are provided for implementing Internet of Things (“IoT”) functionality. In some embodiments, a computing system or IoT management node might receive sensor data from one or more IoT-capable sensors, analyze the sensor data to determine one or more actions to be taken, and identify one or more devices (e.g., household devices associated with a customer premises; vehicular components associated with a vehicle; devices disposed in, on, or along a roadway; devices disposed throughout a population area; etc.) for performing the determined one or more first actions. The computing system or IoT management node then autonomously controls each of the identified one or more devices to perform tasks based on the determined one or more first actions to be taken, thereby implementing smart environment functionality (e.g., smart home, building, or customer premises functionality, smart vehicle functionality, smart roadway functionality, smart city functionality, and so on).
