Abstract: ネットワークの接続に係る異常が発生してから、フレームの送信経路が変更されるまでにかかる時間を、従来よりも短縮する。通信システム（１）は、コントローラ（１０）と、各々が、第３の入出力ポート（２１）と第４の入出力ポート（２２）とを有する複数のスレーブ（２０）とを備える。スレーブ（２０）は、検出部（２５）と、スレーブ送信制御部（２３）とを有する。検出部（２５）は、第３の入出力ポート（２１）の接続に係る異常、および、第４の入出力ポート（２２）の接続に係る異常を検出する。スレーブ送信制御部（２３）は、検出部（２５）が、これら異常を検出したときに、第３の入出力ポート（２１）と第４の入出力ポート（２２）とから、接続状態の変化を検出した旨を示す断線ノード通知フレームの送信を試みる。コントローラは、断線ノード通知フレームを受信すると、通常フレームの送信経路を変更する。

Abstract: Techniques for internet last-mile outage detection are disclosed herein. The techniques include methods for monitoring, by a network appliance associated with a network, a plurality of network nodes, detecting, by the network appliance, that a network node of the plurality of network nodes in a last mile of the network has disconnected from the network, overlaying, by the network appliance, the network node over a network model for at least a portion of the network including the network node to generate a model overlay, and determining, by the network appliance, a last mile outage source associated with a disconnection of the network node by identifying a lowest common ancestor node of the network node from the model overlay. Systems and computer-readable media are also provided.

Abstract: In one embodiment, network node-to-node connectivity verification is performed in a network including data path processing of packets within a packet switching device. In one embodiment, an echo request connectivity test packet, emulating an echo request connectivity test packet received from a first connected network node, is inserted by the packet switching device prior in its data processing path prior to ingress processing performed for packets received from the first connected network node. A correspondingly received echo reply connectivity test packet is intercepted by the packet switching device during data path egress processing performed for packets to be forwarded to the first connected network node.

Abstract: A system and method for traffic classification using snippets and on-the-fly traffic classifiers can build traffic classifiers that leverage interpretable feature sets without the need to inspect payloads ensuring functionality across clear-text and encrypted flows. In one embodiment, the system identifies n-grams ("snippets") in a network flow's sequence-of-message-lengths that are strongly indicative of a given class of traffic and predicts a network flow's class by assessing the presence of snippets relevant to different classes.

Abstract: A system and method for determining human keystrokes in a secure shell (SSH) session from SSH session data traffic provides insight and evidence of an intrusion into a computer network. In one embodiment, the presence of human keystroke(s) in an SSH session may be inferred using a sensor appliance. In one embodiment, the SSH data traffic is encoded in a vector, one or more communication patterns are identified in the vector and the presence of human keystrokes may be inferred from the one or more communication patterns.

Abstract: Methods and systems are provided for providing preemptive actions for predicted data loss during connected gaming using mobile client devices. One example method includes receiving, by a server, data loss from a plurality of mobile client devices. The data loss is used to construct a data loss map that indicates connection quality between said plurality of mobile client devices to the server. The connection quality identifying geolocation data for said plurality of mobile client devices for constructing and updating said data loss map. The method includes receiving, by the server, navigation data for a mobile client device while streaming gameplay from the server. The navigation data is used to identify a route of travel for said mobile client device. The method includes identifying, by the server, a predicted data loss event for the mobile device client. The predicted data loss event is identified using the data loss map and tracking movement of said mobile device client along the route of travel. The method includes sending, by the server, notification data for the predicted data loss event to the mobile client device. The notification data is used for adjusting activity of said gameplay at the mobile client device before reaching a geo-location associated with the predicted data loss event.
