Abstract: A synthetic user profile is generated, representing a synthesized person based on a second person's preferences. The synthetic user profile is modified to improve engagement with the second person based on the second person's interaction with the synthesized person's profile. The synthetic user profile representing the synthesized person is maintained to remember past interaction with the second person between sessions of interaction.

Abstract: An indication of a known condition of a user is received in a computerized system. The system is operable to monitor the user for one or more physical indications related to the known condition, and provide counseling for the known condition to the user responsive to observation of the one or more monitored physical indications via a networked responsive personal guidance system trained on the condition. The networked responsive personal guidance system may be adapted based on the received input from the user, such as to remember a state of prior interactions with the user to provide consistent conversational guidance across multiple login sessions for the user.

Abstract: Techniques are provided for using light path priority of service information in an optical network. At a node in the optical network, priority of service information is stored for a plurality of light paths used in the optical network. The node serves traffic in the optical network using the plurality of light paths based on the priority of service information. These techniques provide for prioritizing light paths (wavelengths) for scenarios such as restoration, congestion and resource contention.

Abstract: In an OTN (Optical Transport Network), an OTN interface of a network element may receive a BDI (Backwards Defect Indicator) signal from a far end network element to which OTN frames are being transmitted. A BDI signal indicates the occurrence of a unidirectional failure in the transmission of OTN frames to which the far end network element responds by switching its routing to the network element. The OTN interface generates an AIS (Alarm Indication Signal) for its network element so that the network element switches network communication channels to the far end network element to ensure bidirectional switching upon a unidirectional failure.

Abstract: 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.

Abstract: 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.

Abstract: Methods and apparatus for efficiently allowing protection switch information to be communicated on bidirectional lines are disclosed. According to one aspect of the present invention, a method for communicating protection switch information from a first network element to a second network element across bidirectional links that include at least one working line and a protection line involves obtaining a generic framing procedure GFP frame at the first network element. The GFP frame has a payload area with a client payload field. The method also includes defining a command field associated with the GFP frame that is in the payload area but not in the client payload field, and storing protection switch information in the command field.

Abstract: In one embodiment, a SONET/SDH over Ethernet demapping point utilizes a pointer offset mechanism for clock recovery and timing. The pointer offset is determined by the difference between a client clock and a reference clock.

Abstract: 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.
