EMS assisted fault handling in virtual network function components

An example operation may include a method comprising one or more of receiving a heartbeat failure notification message when a VNFCI is in standby state, building, at a VNFCI, a next state request message with standby and heartbeat failure parameters, sending the next state request message to an EMS, retrieving, at the EMS, a peer VNFCI state when the next state request message is received, sending a next state response message to the VNFCI with active state when one or more of: a peer VNFCI admin state is not online, and when a peer VNFCI is not reachable when the peer VNFCI admin state is online, sending a next state response message with standby state when the peer operational state is active, and sending the next state response message with standby to the VNFCI when the request of current issues on resources associated with the VNFCI from the VNFM is received and there are critical issues at the EMS.

SYSTEMS AND METHODS FOR MANAGING STREAMS OF PACKETS VIA INTERMEDIARY DEVICES

Virtual application and desktop delivery may be optimized by supplying application metadata and user intent to the device between a client and a server hosting resources for the delivery. The data packets used to deliver the virtual application or desktop may be also tagged with references to the application. By supplying the metadata and tagging packets with the metadata, an intermediary network device may provide streams of data packets at the target QoS. In addition, the device may apply network resource allocation rules (e.g., firewalls and QoS configuration) for redirected content retrieved by the client out of band relative to a virtual channel such as the Internet. The network resource allocation rules may differ for different types of resources accessed. The device may also control a delivery agent on the server to modify communication sessions established through the virtual channels based on network conditions.

Lock reservations for shared storage

Techniques are provided for lock reservations for shared storage. A reserve command to reserve a storage structure is received by a driver from a node. The reserve command is formatted according to a storage protocol. The driver translates the reserve command into a lease acquire command formatted according to an object store protocol and targeting an object stored within an object store and corresponding to the storage structure. A lease identifier derived from a node identifier of the node is inserted into the lease acquire command. The lease acquire command is routed to the object store for obtaining a lease on the object for granting the node exclusive write access to the object.

Systems and methods for pooling multiple user requests to mitigate network congestion

Computer-implemented systems and methods configured to generate a plurality of data packages based on a combination of data elements; add the plurality of data packages to a data package pool configured to store available data packages for assignment; receive an assignment request from a user device in communication with a management server; add the assignment request to a request pool configured to queue a plurality of assignment requests, wherein generating the plurality of data packages and receiving the assignment request occur asynchronously; retrieve a first group of one or more data packages from the data package pool; retrieve a second group of one or more assignment requests from the request pool; assign the one or more data packages of the first group to the one or more assignment requests of the second group; and transmit the one or more assignment requests to corresponding user devices with the assigned data packages.

Virtualization of multiple network functions in high-scale routing

A network processing element and method for using it, are provided for use in a cluster comprising a plurality of network processing elements, wherein the network processing element is configured to enable provisioning of a plurality of different services, wherein the network processing element is configured to store state data associated with one or more functions required for carrying out each of the plurality of different services, and wherein the network processing element is further configured to provide a service or part thereof, based on the state data associated the network processing element's processing resources required for carrying out one or more functions in the provisioning of the requested service.

Early packet loss detection and feedback

A video encoding device (e.g., a wireless transmit/receive unit (WTRU)) may transmit an encoded frame with a frame sequence number using a transmission protocol. The video encoding device, an application on the video encoding device, and/or a protocol layer on the encoding device may detect a packet loss by receiving an error notification. The packet loss may be detected at the MAC layer. The packet loss may be signaled using spoofed packets, such as a spoofed NAM packet, a spoofed XR packet, or a spoofed ACK packet. A lost packet may be retransmitted at the MAC layer (e.g., by the encoding device or another device on the wireless path). Packet loss detection may be performed in uplink operations and/or downlink operations, and/or may be performed in video gaining applications via the cloud. The video encoding device may generate and send a second encoded frame based on the error notification.

EMS assisted split-brain resolution in virtual network function components

A method or system, comprising receiving, at a virtual network function component instances (VNFCI), a heartbeat message from a peer VNFCI with current operational state of active, sending the heartbeat message to the peer VNFCI with a current operational state of active, constructing and sending a next state request message to an element management system (EMS) with one or more of: an active parameter, and a split-brain parameter, starting a response timer, sending a heartbeat message to the peer VNFCI with a current operational state of active and a desired operational state of active when a receive next state response message is received and the VNFCI response state is active.

Shared storage model for high availability within cloud environments

Techniques are provided for a high availability solution (e.g., a network attached storage (NAS) solution) with address preservation during switchover. A first virtual machine is deployed into a first domain and a second virtual machine is deployed into a second domain of a computing environment. The first and second virtual machines are configured as a node pair for providing clients with access to data stored within an aggregate comprising one or more storage structures within shared storage of the computing environment. A load balancer is utilized to manage logical interfaces used by clients to access the virtual machines. During switchover, the load balancer preserves an IP address used to mount and access a data share of the aggregate used by a client.

In-vehicle communication system, relay device, and communication method
11463373 · 2022-10-04 · ·

A relay device directly connected to end nodes in an in-vehicle network transmits a failure detection packet to each end node. When each end node can receive the failure detection packet, each end node transmits a response to the relay device. When the relay device receives the response, the relay device transmits another failure detection packet. The end node determines that the in-vehicle network is normal when the value of the previous failure detection packet does not match the value of the other failure detection packet, and determines that the in-vehicle network is not normal when the value of the previous failure detection packet matches the value of the other failure detection packet.

Maintenance recommendation for containerized services

A maintenance recommendation for containerized services can find a time to perform maintenance on a particular service based on resource usage patterns such that the maintenance will have a reduced impact on dependent services. The dependent services can be determined for the particular service based on network interactions between the services.
