Abstract: Systems and methods for private application access continuity include providing access to one or more private applications for users associated with a tenant of a cloud-based system; detecting one or more criteria suggesting an outage of the cloud-based system; and responsive to activation of a disaster recovery mode based on the one or more criteria, providing access to the one or more private applications via an on-site disaster recovery system including a site controller, wherein providing the access via the site controller does not require communication with the cloud-based system.

Abstract: The present disclosure includes, responsive to a request from a user device, performing a security check based on policy associated with the user device, wherein the policy includes setting related to content filtering and security; responsive to the security check, performing one of: directly allowing the request to the Internet based on the security check determining the request is allowed by the settings; directly blocking the request based on the security check determining the request is disallowed by the settings; and forwarding the request to a system for inline inspection based on the security check determining the request includes suspicious content, wherein responsive to the inline inspection, the request is one of allowed and blocked.

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.

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: 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.
