Abstract: Systems and methods include, responsive to a request to access an application, wherein the application is in one of a public cloud, a private cloud, and an enterprise network, and wherein the user device is remote over the Internet, determining if a user of the user device is permitted to access the application and whether the application should be provided in an isolated browser; responsive to the determining, creating secure tunnels between the user device, an isolation service operating the isolated browser, and the application based on connection information; loading the application in the isolated browser, via the secure tunnels; and providing image content for the application to the user device, via the secure tunnels.

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.

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.
