摘要： The present disclosure generally discloses a network infrastructure virtualization mechanism configured to support virtualization of the network infrastructure (NI) of a communication network to provide thereby a virtualized infrastructure (VI) for the communication network. The network infrastructure virtualization mechanism may be configured to support virtualization of infrastructure resources (IRs) of the network infrastructure to provide virtualized infrastructure resources (VIRs) of the network infrastructure. The IRs of the communication network may include network resources (NRs) which may be virtualized to provide virtualized network resources (VNRs) and service resources (SRs) which may be virtualized to provide virtualized service resources (VSRs). The network infrastructure virtualization mechanism may be configured to support multi-owner virtualization such that multiple owners may share portions of the network infrastructure of the communication network and multi-tenant virtualization such that multiple tenants, at one or more hierarchical layers, may share portions of the network infrastructure of the communication network.

摘要： Disclosed is a method of identifying service topologies in a network, including determining a group of network devices having a same traffic identifier and indicating each network device of the group as not processed, selecting a first network device that is indicated as not processed in the group, indicating the selected first network device as partially processed, and associating the first network device with a service container identifier, identifying, for each port of the selected first network device, at least another network device in the group indicated as not processed connected to the first network device or a termination point, wherein the identified another network device is identified as partially processed and associated with the service container identifier, repeating step (c) for each identified another network device until only termination points are reached, wherein the identified another network device becomes the first network device in step (c), and when any network devices in the group of network devices remain not processed repeating the steps (b)-(d).

摘要： Various embodiments relate to a method performed by a network node for terminating an S9 roaming session, the method including: receiving a Gx roaming session termination request; forwarding a corresponding S9 roaming session termination request to a controlling Policy and Charging Rule Function (PCRF) node; waiting a preconfigured time interval; and terminating the S9 roaming session without receiving an expected S9 acknowledgement message from the controlling PCRF node. Embodiments can include scheduling an IPCAN session audit for a selected IPCAN session of an S9 roaming session at preconfigured time intervals; generating an IPCAN session status request message; converting the IPCAN session status request message to a corresponding S9 status request message; forwarding the S9 status request message to a visited PCRF node; and responsive to receiving an S9 message indicating an unknown session from the visited PCRF node, removing the selected IPCAN session at the network node.

摘要： We disclose a modular fiber-interconnect device that can be used in a ROADM to optically interconnect wavelength-selective switches and optical add/drop blocks thereof. An example module of the modular fiber-interconnect device has seventeen optical ports, each implemented using an MPO connector of the same type. The number of (nominally identical) modules in the modular fiber-interconnect device depends on the degree N of the ROADM and can vary, e.g., from two for N=4 to fourteen or more for N≥20. A proper set of duplex optical connections within the ROADM can be created in a relatively straightforward manner, e.g., by running MPO cables of the same type from the wavelength-selective switches and the optical add/drop blocks of the ROADM to appropriate optical ports of the various modules of the modular fiber-interconnect device.
