Predictive routing using machine learning in SD-WANs

In one embodiment, a supervisory service for a software-defined wide area network (SD-WAN) obtains telemetry data from one or more edge devices in the SD-WAN. The service trains, using the telemetry data as training data, a machine learning-based model to predict tunnel failures in the SD-WAN. The service receives feedback from the one or more edge devices regarding failure predictions made by the trained machine learning-based model. The service retrains the machine learning-based model, based on the received feedback.

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 NACK 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.

Information processing apparatus and verification system
11088960 · 2021-08-10 · ·

An information processing apparatus includes a processor that obtains a flow table from a switch apparatus that processes packets by using the flow table. The processor creates, for each flow registered with the flow table, a verification packet based on identification information that identifies each flow. The processor determines a number of verification packets based on a count value that represents a number of actual packets that have arrived at the switch apparatus. The processor generates the number of verification packets for each flow by copying the verification packet created for each flow. The processor determines transmission order of the generated verification packets based on the count value for each flow and time information that represents a time when a final actual packet of each flow has arrived at the switch apparatus.

PERSISTENT VOLUMES FOR STATEFUL APPLICATIONS

Systems and methods for implementing stateful services using cloud-based resources are described. A server computing system determines existence of a first volume based on a launch of a first instance by an auto-scaling group (ASG). The first volume is to have a resource tag having a value similar to a value of a resource tag of the ASG. The first volume was previously attached to a second instance terminated by the ASG. Based on a successful determination of the existence of the first volume, the server computing system attaches the first volume to the first instance. Based on a failed determination of the existence of the first volume, the server computing system generates a second volume, attaches the second volume to the first instance, and set a resource tag of the second volume to a value similar to the value of the resource tag of the ASG.

Load balancing for IP failover

Techniques are provided for load balancing for IP failover. A backend address of a first node is identified as a routing destination to which a request is to be routed by a load balancer based upon a load balancer rule mapping a frontend address, specified by the request as a request destination, to the backend address of the first node. The request is routed to a primary network interface of the first node using the backend address. The first node has a loopback interface with an address matching the frontend address for routing the request to a destination data structure based upon the request maintaining the frontend address as the request destination. Health probes are used by the load balancer for detecting a failure of the first node in order to failover to routing requests to a second backend address of a second node.
