    摘要： The invention is a tool that accurately predicts the performance of each different priority or service level on a PON with multiple different service types and multiple users. Delays and bit rates are computed accounting for all packet, protocol, propagation, and scheduling overhead. The performance and delays of all services are further verified by running a real-time simulation that identically mimics the operation of an actual PON, resulting in very close prediction of the performances of different services before the services are actually used or tested for use by the subscribers. The invention allows the service provider to sell the maximum number of services possible, while still ensuring that they can all function acceptably. The tool may be used to model and predict behavior of various PON.

    摘要： The embodiments of the present invention relate to the field of communications technologies, and disclose a lossless adjustment method of ODUflex channel bandwidth and an ODUflex channel. The lossless adjustment method includes: respectively adjusting, according to bandwidth adjustment indication request information, a time slot occupied by an ODUflex frame in a higher order optical channel data unit at an egress side of each network node on an ODUflex channel; and adjusting, according to rate adjustment indication information, a transmission rate of the ODUflex frame of each network node on the ODUflex channel, to enable the transmission rate of each network node on the ODUflex channel to be unified. The embodiments of the present invention achieve the lossless adjustment of ODUflex channel bandwidth by respectively adjusting a time slot occupied by an ODUflex frame in a Higher Order Optical Channel Data Unit at an egress side of each network node on an ODUflex channel, and adjusting a transmission rate of an ODUflex frame of each network node on the ODUflex channel.

    摘要： A mechanism for recovering reserved resources in a wavelength-division-multiplexed based photonic burst switched (PBS) network in response to resource non-availability. The PBS network includes edge and switching nodes, which optically communicate information formatted into PBS control and data burst frames. Each PBS data burst frame is associated with a PBS control burst frame. A PBS control burst is sent to reserve resources along a lightpath comprising a concatenation of lightpath segments linked between in ingress edge nodes, switching nodes and egress edge nodes. During a subsequent data burst, an, unavailable resource is detected at one of the switching nodes. In response, a resource cancellation message (RCM) comprising a control burst is sent to upstream and/or downstream nodes along the lightpath. Upon receiving the RCM, the corresponding resource reservation is cancelled, freeing the network resources for subsequent bandwidth reservations and access.

    摘要： A method of establishing a data connection between terminal switching nodes in a network and switching nodes for implementing the method. The method involves switching nodes participating in a network layer wavelength routing (WR) protocol to determine the next hop switching node for every possible combination of terminal nodes based on the network topology. The method also involves the switching nodes participating in a network layer wavelength distribution (WD) once the data connection is to be established. The WR protocol determines the path used through the network, while the WD protocol assigns wavelengths on each link between switching nodes. The wavelengths may be different on different optical links. The switching nodes include wavelength converters with an optical switch or optoelectronic converters with a digital electronic switch. A digital electronic switch can also provide signal reformatting. Advantages of using potentially different wavelengths along various segments of a single end-to-end connection yields increased wavelength efficiency.

    摘要： The aim of the present invention is to achieve a low delay and high bandwidth efficiency in an upstream bandwidth and to accurately reflect assured bandwidth in an actual transmitted bandwidth. To achieve this, in the present invention the maximum value and the transmission cycle of a requested bandwidth are set for each service class. The present invention allocates bandwidth to a service path terminating section based on excess allocated bandwidth and requested bandwidth of each service path terminating section. For each service path terminating section the present invention also selects one bandwidth out of a plurality of bandwidths requested by a service path terminating section in such a manner that the sum value of the allocated bandwidths of the plurality of service path terminating sections is within a predetermined range.
