Abstract: Methods, systems, and apparatuses for discovering dynamic path maximum transmission unit (PMTU) between a sending computing device and a receiving computing device (e.g., a client device and a host device) are described herein. A sending computing device may iteratively transmit bursts of probe packets, each burst being defined by a search range between a maximum packet size and a minimum packet size. The sending computing device may iteratively update the search range based on the previous iteration until the search converges on the PMTU. When the PMTU is discovered, each of the computing devices may update their transport and presentation layer buffers based on the discovered PMTU without any other protocol level disruption. In a multi-path scenario, the computing device may discover PMTU for each of the paths and select a performance optimal path based on the individual PMTUs and other network characteristics such as loss, latency, and throughput.

Abstract: Methods and systems for performing one or more path selection processes that determine connection conditions and send the data via established, multi-path, connections are described herein. The one or more path selection processes may be performed in a remote computing environment where the established, multi-path, connections are between two endpoint devices and are available to communicate data for a remote application and/or a remote desktop. Based on the one or more path selection processes, data for the remote application and/or the remote desktop may be sent via a connection that differs from connection assignments that were configured when the connections were initially established. Additionally, as part of the one or more path selection processes, routing information that indicates a routing path may be inserted into data sent via the connections. An intermediary device may be caused to route the data according to the routing path indicated by the routing information.

Abstract: Described embodiments provide systems and methods for determining a scale for buffers of a session. A device may identify a round trip time (RTT) of a session with a client for which one or more of a plurality of buffers are provided. The device may detect an indication in advance of an activity on the client to access through the session. The device may determine, responsive to detecting the indication, a scale based at least on a type of the activity. The device may set a number for the plurality of buffers to provide for the session in accordance with the scale and the RTT.

Abstract: The present solution provides systems and methods for providing remote access and packet retransmission via third party networks. A device can receive a client request to establish a session with a virtual server. The client and the virtual server can communicate using a presentation services protocol over a lower-level protocol. The device can select a node on a network to use for the session between the client and the virtual server. The device can cause an installation of one or more network stacks on the node, the one or more network stacks configured to communicate with the client and the virtual server using the presentation services protocol over the lower-level protocol and to handle retransmissions of packets between the client, the node, and virtual servers. The device can cause each of the client and the virtual server to establish the session via the node.
