摘要： Validating a path in an optical layer of a communications network, for client traffic having an associated service level, involves setting an optical quality margin according to the service level associated with that client traffic. The optical quality margin indicates how close an estimated optical quality of the path can approach a level which produces a threshold error rate. This margin is used to check whether the estimated optical quality is within the optical quality margin set according to the client traffic service level. Making the optical quality margin dependent on client traffic service level, can enable increased optical reach. This can give more flexibility in path selection and enable better matching to service levels of client traffic.

摘要： Apparatus and methods are provided for application layer optimization in a modem data network. The optimization incorporates variable rate transmission across one or more optical data channels. Data throughput is maximized by enabling quality of service profiles on a per transmission channel basis. According to one aspect, a system is provided in which the application layer is aware of and controls the underlying transmission rate and quality of the transmission. This enables the system to fully utilize the transmission capacity of the channel. The application layer may map different applications to different transmission classes of service. The services can be classified based on data throughput rate, guaranteed error rates, latency and cost, among other criteria. This provides flexibility to the application layer to map some loss tolerant applications to a lower cost (per bit) transmission class.

摘要： The invention provides a method of simulcasting data fragments sent over a first packet-switched computer network to a trunk network and redistributed over a second packet-switched computer network. A method is provided comprising the steps of providing a trunk network including multiple links including an RF link and a fiber link, wherein all the transmission links transmit data packets to a receiver which will redistribute the earliest data packets with a matching frame check sequence (FCS) over the second packet switched computer network. The method provides for a sender for adding an incremental sender sequence number and sender FCS to the data packets, creating a sender data packet. Transmitting a sender data packet, simulcast over the transmission links, receiving, by a receiver, via the fastest links which may drop or change some bits unintentionally, a sender data packet and receiving, by the receiver, via slower links which are unlikely to drop or change some bits unintentionally, a sender data packet. The method provides for checking, by the receiver, a receiver calculated FCS of the received sender data packet and comparing them to the sender FCS that was added by the sender. Transmitting over the second packet-switched computer network, the first sender data packet with the next sequence number increment after the incremental sender sequence number and verifying sender FCS, verifying, by the receiver, the sender data packets and identifying, by the receiver, a gap between sender data packets, queueing up verified sender data packets when there is a gap in the verified sender data packets and sending all verified sender data packets in sequence order, once the gap is filled by any transmission link.

摘要： A method and apparatus for control and data burst routing in WDM photonic burst-switched network is disclosed. In one embodiment, only the control bursts and network management labels are going through optical-electrical-optical conversion inside the photonic burst switching (PBS) module. The building blocks of the control processing unit inside the PBS module may include input and output buffers, control burst parser, burst scheduler, PBS configuration and control, contention resolution, forwarding engine, network management controller, control burst generator, and queue manager. The contention resolution block may be used to resolve resource contention between multiple data bursts. Such contention resolution may take the form of adding additional delays to one of the data bursts, changing one of the data bursts to an alternate wavelength, or dropping some of the data bursts based on various criteria such as relative priority and wavelength.

摘要： To more fully utilize the available bandwidth of a network link, network nodes in accordance with the present invention allow TDM data to be combined with packet data. A Packet/TDM cross connect switch, having both a TDM switch and a packet switch, is used in these embodiments. Data packets are transformed into TDM packet columns. The TDM packet columns are combined with standard TDM data columns in the payload of a TDM data frame. Data packets may be sorted based on a priority scheme, in which high priority data packets are given precedence over lower priority data. However, both high priority and low priority may be combined in a TDM packet column.
