  • Patent number: 11909653
    Abstract: Example methods and systems for self-learning packet flow monitoring. One example method may comprise monitoring a packet flow to identify attribute information associated with the packet flow between a source and a destination; and classifying the packet flow using a classification engine that is trained using a training dataset to determine a classification output associated with the packet flow. The example method may also comprise providing, to a user device, a user interface (UI) that includes a visualization of the packet flow and the classification output; requesting, via the UI, a feedback associated with the classification output for the packet flow; and updating the classification engine or the training dataset based on the feedback from the user device.

  • Patent number: 11870601
    Abstract: Systems, methods, and devices can be utilized for policy control function (PCF) fallback during the set up of a session utilizing a 5th Generation (5G) core network. An example method includes receiving, from a session management function (SMF), a request for a policy corresponding to a session. The request includes a first policy identifier corresponding to a first policy control function (PCF). The example method further includes determining that the first PCF is unavailable, generating a modified request by replacing the first policy identifier with a second policy identifier in the request. The second policy identifier corresponds to a second PCF. The example method also includes transmitting, to the second PCF, the modified second request.

  • Patent number: 11856097
    Abstract: A network interface card, such as a SmartNIC, is used to provide encryption, such as network encryption virtual function (NEVF), for a virtual machine, so that a customer can control network keys in a virtual cloud network. The NEVF includes a memory device (e.g., SRAM) and a crypto processor (e.g., a crypto core). The memory device stores a crypto key. The crypto processor uses the crypto key to encrypt data to and from a virtual machine in the virtual cloud network. A key management system can be used to securely transfer crypto keys to the NEVF. Having one NEVF per virtual machine can enable a customer to manage the crypto key for a virtual cloud network.

  • Patent number: 9985838
    Abstract: The techniques described are directed to providing mass withdrawal of media access control (MAC) routes for network devices in an Ethernet virtual private network data center interconnect (EVPN DCI). MAC routes to reach the learned MAC addresses are stored in routing tables with corresponding top-of-rack Ethernet segment identifier (TOR-ESI) values that represent the Ethernet segments from where the MAC addresses were learned. A provider edge (PE) network device may configure and advertise a virtual Ethernet segment identifier (vESI) that includes a plurality of TOR-ESI values. As Ethernet segments of the data center become unavailable, the corresponding TOR-ESI values may be withdrawn from the vESI to form an updated vESI. In this way, MAC routes having a TOR-ESI value that was withdrawn from the vESI may be removed from the routing tables in each of the network devices.

  • Patent number: 9781074
    Abstract: A method for sending a cloud server address to a desktop cloud terminal, where a terminal management server receives a request message from a desktop cloud terminal, obtains, by means of parsing, an address of the desktop cloud terminal carried in the request message, queries a mapping table according to the address of the desktop cloud terminal, acquires an address of a cloud server accessible to the desktop cloud terminal, generates a request response message, and sends the request response message to the desktop cloud terminal, where the request response message carries the address of the cloud server accessible to the desktop cloud terminal. Therefore a system administrator does not need to manually configure the cloud server address on the terminal management server for the desktop cloud terminal, and a desktop cloud terminal user does not need to manually configure the desktop cloud terminal.

    Abstract: Methods and systems for transmitting data are presented. In an example embodiment, data streams from one or more media content sources are received into one or more buffers. Each of the data streams includes contiguous, non-overlapping data sets of a first media content, and each of the data streams has a unique data rate relative to one or more of the other data streams. A request is received from a device to stream a next segment of the first media content from one of the data streams to the device, the next segment including one or more of the data sets of the first media content. In response to the request, the next segment is streamed from the one of the data streams via a buffer to the device.

  • Patent number: 9692693
    Abstract: Techniques are described for specifying and constructing multi-protocol label switching (MPLS) rings. Routers may signal membership within MPLS rings and automatically establish ring-based label switch paths (LSPs) as components of the MPLS rings for packet transport within ring networks. In one example, a router includes a processor configured to establish an MPLS ring having a plurality of ring LSPs. Each of the ring LSPs is configured to transport MPLS packets around the ring network to a different one of the routers operating as an egress router for the respective ring LSP. Moreover, each of the ring LSPs comprises a bidirectional, multipoint-to-point (MP2P) LSP for which any of the routers can operate as an ingress to source packet traffic into the ring LSP for transport to the respective egress router for the ring LSP. Separate protection paths, bypass LSPs, detours or loop-free alternatives need not be signaled.

  • Patent number: 9621470
    Abstract: Existing resource reservation techniques are inefficient for M2M communications. In an example embodiment described herein, a system comprises a service layer server that resides on a service layer and a control plane node that resides on an access network, wherein the service layer server communicates with the control plane node via a control plane interface. The control plane interface can be used to configure quality of service (QoS) policies (rules) that are based on an object that is being addressed. In this context, for example, an object may be a memory location or value. For example, the service layer may configure one or more QoS rules for the access network based on the object by sending a QoS provisioning message that includes one or more parameters to the control plane node. The control plane node may determine the object that is identified in the one or more QoS rules, and the QoS rules may be distributed to one or more routers that may be used to access the object.

  • Patent number: 9609059
    Abstract: Methods and apparatuses, including computer program products, are described for synchronization of shared initial filter criteria in an IP Multimedia Subsystem (IMS) network. A first computing device in the IMS network transmits a registration request to a second computing device in the IMS network. The first computing device receives a response to the registration request from the second computing device, including an identifier associated with a shared initial filter criteria set stored at the first computing device. The first computing device determines whether the shared initial filter criteria set corresponding to the identifier is stored at the first computing device and transmits a retrieval request to the second computing device if the shared initial filter criteria set corresponding to the identifier is not stored. The first computing device receives the shared initial filter criteria set from the second computing device, and stores the shared initial filter criteria set.
