Abstract: In one embodiment, a network assurance service that monitors a wireless network receives data regarding connection failures of a wireless client of the wireless network. The network assurance service forms a behavioral profile for the wireless client based on the received data regarding the connection failures of the wireless client. The network assurance service uses machine learning to determine whether the behavioral profile of the wireless client is an outlier in relation to behavioral profiles of other wireless clients of the wireless network. The network assurance service causes performance of a mitigation action with respect to the wireless client, when the wireless client is determined to be an outlier.

Abstract: One embodiment provides a system that facilitates routable prefix queries in a CCN. During operation, the system generates, by a client computing device, a query for one or more indices based on a name for an interest, wherein a name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level. An index indicates a number of the contiguous name components beginning from the most general level that represent a routable prefix needed to route the interest to a content producing device that can satisfy the interest. In response to the query, the system receives the one or more indices, which allows the client computing device to determine a remaining number of name components of the interest name which can be encrypted, thereby facilitating protection of private communication in a content centric network.

Abstract: Offloading of location computation from a location server to an access point through the use of projections on base phase vectors may be provided. First, an Access Point (AP) may receive a set of two or more base phase vectors from a location server. Next, the AP may measure a measured phase vector for a first signal from a user device.

From these comparisons, the AP can determine a subset of base phase vectors with the highest projection values. The AP can then send the projection values and the subset of base phase vectors to the location server, wherein the location server determines the device location from these projection values and subset of base phase vectors.

Abstract: In one embodiment, a particular device along a path in a deterministic network receives a first packet sent from a source towards a destination via the path. The particular device sends the first packet to a next hop device along the path, according to a deterministic schedule associated with the first packet. The particular device determines, after sending the first packet, an action to be performed on the first packet. The particular device then sends a second packet to the next hop device indicative of the determined action. The second packet causes another device along the path to perform the action on the first packet.

Abstract: In one embodiment, a device in a network splits each of a plurality of packets of two or more data streams into an equal number of fragments. The number of fragments for packets of a particular one of the streams controls the level of error correction for that stream. The device generates recovery symbols for the fragments for each of the plurality of packets. Each of the plurality of packets has an equal sum of fragments plus recovery symbols. The device multiplexes the fragments and recovery symbols for each of the packets, to form a set of new packets. The device sends the set of new packets to one or more recipients in the network.
