  • Patent number: 10375024
    Abstract: A virtual private access method implemented by a cloud system, includes receiving a request to access resources from a user device, wherein the resources are located in one of a public cloud and an enterprise network and the user device is remote therefrom on the Internet; forwarding the request to a central authority for a policy look up and for a determination of connection information to make an associated secure connection through the cloud system to the resources; receiving the connection information from the central authority responsive to an authorized policy look up; and creating secure tunnels between the user device and the resources based on the connection information.

  • Patent number: 10187307
    Abstract: A system and method for implementing transmission parameter control at a transmitting station is described. The exemplary system and method comprises querying a transmission parameter control module for a transmission schedule. The transmission schedule comprises at least one schedule entry defining a set of transmission parameter controls as they pertain to a destination address. At least one packet of data is then transmitted to the destination address according to the transmission parameters controls of at least one schedule entry from the transmission schedule. A system and method for selecting an antenna configuration corresponding to a next transmission of packet data is also disclosed.

  • Publication number: 20180270201
    Abstract: Virtual private access systems and methods implemented in a clientless manner on a user device include receiving a request to access resources from a Web browser on the user device at an exporter in a cloud system, wherein the resources are located in one of a public cloud and an enterprise network and the user device is remote therefrom on the Internet; performing a series of connections between the exporter and i) the Web browser and ii) centralized components including a crypto service, database, cookie store, and Security Assertion Markup Language (SAML) Service Provider (SP) component to authenticate a user of the user device for the resources; and, subsequent to authentication, exchanging data between the Web browser and the resources through the exporter, wherein the exporter has a first secure tunnel to the Web browser and a second secure tunnel to the resources.

  • Publication number: 20180124575
    Abstract: Systems and methods for improving data transmission rates in communication networks are disclosed. In an 802.11 wireless communication network, where a source node of the wireless network transmits TCP data to a destination node of the wireless network, the destination node does not transmit TCP acknowledgments (ACKs) for the TCP data if 802.11 ACKs indicate that the destination node received the TCP data. If a source outside the wireless network transmits TCP data to the destination node within the wireless network through an intermediate device, such as an access point, the destination node suppresses transmitting TCP ACKs. The intermediate device transmits TCP ACKs as proxy for the destination node to the source. The intermediate device also suppresses TCP ACKs where a source node within the wireless network sends the TCP data to a destination node outside of the wireless network.

  • Publication number: 20180113807
    Abstract: A Dynamic Name Server (DNS) surrogation method, a DNS system, and a DNS server provide DNS surrogation which is the idea that if a user device sends a DNS resolution request to a given DNS server that server does not need to actually perform the recursion itself. A policy can be defined telling the server that first received the request to take other factors into account and “relay” or “surrogate” that request to another node. This additional node is called a “surrogate” and it actually performs the recursion therefore allowing the resolving party to perform proper localization, optimization, or any other form of differentiated resolution. This surrogation also distributes the job of actually performing resolution, which adds scalability to the DNS server or service itself. A network of “surrogate” resolvers is possible as well as the concept of every client needing DNS resolution can also become a surrogate.

  • Publication number: 20170310709
    Abstract: A cloud-based security method using Domain Name System (DNS) includes receiving a request from a user device at a DNS server; performing a security check on the request based on a policy look up associated with the user device; responsive to the policy look up, performing a DNS security check on the request; and responsive to the DNS security check, performing one of allowing the request to the Internet; blocking the request based on the policy; and providing the request to inline inspection based on the policy, wherein the request is one of allowed to the Internet or blocked based on the inline inspection.

  • Patent number: 9705922
    Abstract: A cloud-based method, system, and transparent proxy for user-level policy, reporting, and authentication over Domain Name System (DNS) include maintaining a local user Internet Protocol (IP) database identifying users in an enterprise; and acting as a transparent proxy for all DNS requests from the users performing the steps of: for a user already identified in the local user IP database, forwarding a DNS request to a cloud-based system with an identifier from the local user IP database of the user associated with the DNS request; and for the user not identified in the local user IP database, performing a series of redirects and hand offs in the cloud-based system to identify the user.

  • Patent number: 9071942
    Abstract: An access point of a communications network receives a multicast or broadcast packet from a source. The access point converts the multicast or broadcast packet into a unicast packet addressed to a station associated with the access point. The access point then transmits the unicast packet over the communications network from the access point to the station. The access point further may determine a minimum data rate by which the access point may transmit the multicast or broadcast packet to the station and determines an effective unicast rate for transmitting the unicast packet to the station. If the effective unicast rate does not exceed the minimum data rate, the access point does not transmit the unicast packet to the station and transmits the multicast or broadcast packet.
