Assignee:

Airmagnet, Inc. - Sunnyvale CA

International Classification:

H04L 12/28

US Classification:

370252, 370338

Abstract:

In one exemplary embodiment, voice quality of Voice over IP data in a wireless network is measured by first receiving at a detector in the wireless network a set of wireless frames transmitted between a first wireless device and a second wireless device in the wireless network in a predetermined time period. The wireless frames in the set carry Voice over Internet Protocol data. A rating value indicative of voice quality is determined based on the loss rate and burst rate that are determined only using frames received by the detection during monitoring.

International Classification:

US Classification:

370252, 370338

Abstract:

In one exemplary embodiment, a process for detecting a phone includes monitoring wirelessly transmitted traffic between first and second stations. Next, the process determines whether the traffic sent in both directions between the first and second stations are close to each other in term of traffic volume. The process identifies a total frames count of a number of frames of an identical frame size transmitted, where the number of frames is greater than any number of frames of a same size. The process calculates the percentage of the count that was just collected out of the count of the total frames. The process identifies the first station as a phone if the calculated percentage is over a first threshold and the total frames count is over a second threshold.

International Classification:

G06F 15/173

US Classification:

709224

Abstract:

A backend server for a peer-to-peer network manages nodes according to a pod-based management scheme. Each pod comprises a plurality of nodes and only nodes within the same pod can directly share data in the peer-to-peer network. The server dynamically allocates nodes to pods and dynamically allocates computing resources for pushing data to the pods based on characteristics of the incoming data stream and performance of the peer-to-peer sharing. By dynamically adjusting the pod structure and resources available to them based on monitored characteristics, the server can optimize performance of the peer-to-peer network.

International Classification:

G06F 15/16

US Classification:

709227

Abstract:

A message passing protocol allows two clients to establish a connection even when the clients are behind different NAT devices such as NAT firewalls. Beneficially, the protocol does not require that either client has knowledge of where the other client is located (e.g., behind the same NAT device or behind a different NAT device). When two clients want to establish a connection, the clients exchange identifying information with each other by passing the information through a rendezvous server. Based on the identifying information, each client determines and sends a plurality of synchronization packets to a number of different predicted addresses. When synchronization packets reach the actual addresses of both devices, a connection can be established between the clients.

International Classification:

G06K 9/62
G06N 3/08

Abstract:

The present disclosure provides an improved training methodology that enables supervised contrastive learning to be simultaneously performed across multiple positive and negative training examples. In particular, example aspects of the present disclosure are directed to an improved, supervised version of the batch contrastive loss, which has been shown to be very effective at learning powerful representations in the self-supervised setting. Thus, the proposed techniques adapt contrastive learning to the fully supervised setting and also enable learning to occur simultaneously across multiple positive examples.

G06Q 30/02

Abstract:

Techniques for automatically creating geographic region groups are provided. Attribute data about a plurality of regions is stored. Based on the attribute data, each region is classified as belonging to a tier of multiple tiers. A first set of region groups is generated, where each region group includes at least two regions assigned to different tiers. For each region group, group attribute data for that region group is generated. A comparison of first group attribute data of a first region group is performed with group attribute data of each other region group. Based on results of the comparison, first arrangement data that associates a second region group with the first region group is stored.
