摘要： In a traffic engineering technique, a determination is made as to whether any path of a number of predetermined paths meets requirements corresponding to a request. The predetermined paths are determined by substantially maximizing carried demand using at least traffic demand estimates and network topology information and by performing routing for the substantially maximized carried demand. If a given path meeting the requirements is found, a connection on the given path is created, if possible. The predetermined paths are determined through offline TE techniques referred to herein as offline design-based routing (DBR). The requirements for the path may include a destination address and a bandwidth. The offline DBR techniques can include uncertain static demand information or dynamic connections. The offline DBR techniques may be used with adaptive DBR techniques, such that paths are determined offline if possible but can also use shortest path first (SPF), constrained SPF (CSPF) or other techniques during an online path determination. An improvement to a conventional CSPF technique is also presented.

摘要： In a system and method of optical communication, optical signals are generated in multiple wavelength channels. Each optical signal is passively transported from an origination node of a network to a destination node. The destination node is determined by the signal wavelength. For at least some signals, the passive transport includes transport through a branch point of the network, such that the signal wavelength determines the output branch through which the signal is routed. In certain embodiments, signals are generated according to a schedule devised to substantially prevent the concurrent arrival, at the same destination node, of signals having the same wavelength but coming from different origination nodes.

摘要： Flow control techniques are disclosed for use in data communications networks such as those implementing a time-domain wavelength interleaved network (TWIN) architecture or other suitable architectures. Such techniques may provide for congestion management and scheduling for asynchronous traffic. For example, in one aspect, a technique comprises collecting information at a node of an optical-based communications network, wherein at least a portion of the collected information pertains to congestion in the optical-based communications network, and adjusting a transmission rate of the node in response to at least a portion of the collected information such that the node operates under a substantially stable transmission schedule with respect to asynchronous data bursts. The transmission rate adjusting step/operation may further comprise adjusting the transmission rate such that the node operates under a substantially fair transmission schedule. The node may operate under a random transmission schedule.
