Abstract: Techniques for using Home Addresses, Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to obfuscate server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a Home Address that is mapped to the client device and at least one server IP address of the endpoint device. In this way, IP addresses of servers are obfuscated by a network mapping of the Home Addresses and the server IP addresses. The client device may then communicate data packets to the server using the Home Addresses as the destination address, and a virtual network service that works in conjunction with DNS can encapsulate the data packet with the server IP addresses and forward the data packet onto the server.

Abstract: Systems, methods and computer-readable storage media are provided for determining critical flow characteristics and predicting the network resources to compute time-based p-routes that satisfy different SLAs. Critical flows within a set of nodes organized in a DODAG are monitored and assessed according to applicable SLAs and relevant networking KPIs to generate a forecast of the traffic flow and the overall SLAs for these critical flows. These overall SLAs, KPIs, and the generated forecast are used by a PCE associated with the network to compute p-routes through the set of nodes in the DODAG that satisfy the overall SLAs for the critical flows.

Abstract: Multimodal wireless and deterministic mode operation may be provided. An indication may be provided to a client device by an Access Point (AP) that the AP supports multimode operation and which current sub-mode is enabled. Then a determination may be received from the client device to perform an operation based on the indication that the AP supports multimode operation and which sub-mode is currently enabled wherein the operation comprises one of prefer the AP and avoid the AP.

Abstract: Leveraging wireless direct transmissions may be provided. It may be determined that data traffic flowing on a first pathway between a first client device and a second client device is not meeting a predetermined service level. The first pathway may be partially wired and partially wireless. A second pathway that will meet the predetermined service level may be determined. The second pathway may be wireless. The data traffic may be caused to flow on the second pathway.

Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a virtual IP (VIP) address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a virtual network of VIP addresses. The client device may then communicate data packets to the server using the VIP address as the destination address, and a virtual network service that works in conjunction with DNS can convert the VIP address to the actual IP address of the server using NAT and forward the data packet onto the server.

Abstract: In one embodiment, an illustrative method herein may comprise: obtaining, by a process, operational performance metrics associated with one or more devices performing an operation and contemporaneous situational sensor data associated with the one or more devices performing the operation; establishing, by the process, a correlation between a health of the operational performance metrics and the contemporaneous situational sensor data for the one or more devices while performing the operation; determining, by the process, an adjustment to increase the health of the operational performance metrics for a particular device of the one or more devices based on the correlation; and communicating, by the process, the adjustment to a receiving device to facilitate adjusting of the particular device.

Abstract: A device for a virtual phone in a virtual network may be provided. A data packet may be received by the device, the device being in a personal-area-network (PAN) with a peer, the data packet containing information defining a characteristic of a software application. The data packet may be profiled, the data packet comprising information about the software application. An SLA table stored on the device may be seeded with the information in the data packet. A routing table may be populated with an address for forwarding the information to the peer.

Abstract: In one embodiment, a method comprises: generating, by a constrained low power and lossy network (LLN) device that is localized within a subregion of an LLN, a thin destination oriented directed acyclic graph (DODAG) having up to a prescribed limit of attached LLN devices at each hop of the thin DODAG based on generating a DODAG information object (DIO) message specifying an instruction for limiting attachment at each hop of the thin DODAG to the prescribed limit; and causing, by the constrained LLN device, multicast-only transmissions via the thin DODAG based on inserting into the DIO message a multicast-only transmission mode via the thin DODAG and outputting the DIO message, the DIO message causing each neighboring LLN device to selectively attach to the constrained LLN device as an attached child LLN device based on the instruction and execute the multicast-only transmissions via the thin DODAG.

Abstract: A method includes receiving, at a home controller of a home domain and from a first device in the home domain, a first message concerning a user device that is anchored to the home domain and that has roamed from the home domain to a visitor domain. The method also includes, in response to determining that the first device is a router, opening a tunnel between the home controller and a visitor controller of the visitor domain and communicating the first message to the user device through the tunnel. The method further includes receiving, at the home controller and from a second device in the home domain, a second message concerning the user device and in response to determining that the second device is not a router, communicating, to the second device, a proxy response to the second message.
