摘要： Various example embodiments are disclosed. According to an example embodiment, a method may include receiving a resource request for optical resources within a wavelength division multiplexed (WDM) optical network; comparing one or more parameters of the resource request to a list of pre-validated paths for the WDM optical network, each pre-validated path identifying an optically feasible label switched path between a source node and a destination node; determining that there is a pre-validated path on the list that matches the one or more parameters of the optical resource request; and sending a message to request a reservation of resources along the matching pre-validated path.

摘要： Techniques and a control architecture (apparatus and logic) are provided for an adaptive hybrid DWDM-aware computation scheme. The architecture is one that is a hybrid of a centralized control scheme and a distributed control scheme that performs adaptive physical impairment computations for an optical network. A central control server is connected to multiple client control devices each of which resides in a node in a dense wavelength division multiplexed (DWDM) optical network, wherein each client control device is part of an optical control plane associated with the optical network. The control server obtains data for path route analysis from the client control devices. The control server then determines optical feasibility of at least one path route from a source node to a destination node from optical parametric information based on the data obtained from multiple client control devices and without real-time communication between the central control server and the multiple client control devices while performing the optical feasibility computations.

摘要： Techniques are provided for detecting at a controller associated with a physical layer of a network an occurrence of a failure within the physical layer of the network. In response to detecting the failure, the controller sends messages to at least first and second nodes in a transport layer of the network, where the messages are configured to indicate normal operations in the physical layer so as to prevent execution of transport layer protection processes for a period of time.

摘要： Systems and methods for operating transponders that automatically accommodate multiple received signal types. The different signal types may include different clients such as, e.g., SONET/SDH, G.709, 10 Gigabit Ethernet, etc. as well as different data rates. A transponder can automatically detect the client signal type and data rate and respond by processing the received signal appropriately, notifying a control processor, and invoking an appropriate performance monitoring method. This maximizes the network operator's flexibility and ease of configuration.
