-* RDP Shortpath transport is based on top of highly efficient  [Universal Rate Control Protocol (URCP)](https://www.microsoft.com/en-us/research/publication/urcp-universal-rate-control-protocol-for-real-time-communication-applications/). URCP enhances UDP with active monitoring of the network conditions and provides fair and full link utilization. URCP operates at low delay and loss levels as needed by Remote Desktop. URCP achieves the best performance by dynamically learning network parameters and providing protocol with a rate control mechanism.
-* RDP Shortpath establishes the direct connectivity between Remote Desktop client and Session Host. Direct connectivity reduces the dependency on the Azure Virtual Desktop gateways, improves the connection's reliability, and increases the bandwidth available for each user session.
-* The removal of extra relay reduces the round-trip time, which improves user experience with latency-sensitive applications and input methods.
-* RDP Shortpath brings support for [configuring Quality of Service (QoS)](./rdp-quality-of-service-qos.md) priority for RDP connections through a Differentiated Services Code Point (DSCP) marks
-* RDP Shortpath transport allows [limiting outbound network traffic](./rdp-bandwidth.md#limit-network-bandwidth-use-with-throttle-rate) by specifying a throttle rate for each session.

 5. After establishing the Shortpath transport, RDP moves all Dynamic Virtual Channels (DVCs), including remote graphics, input, and device redirection, to the new transport.
 6. If a firewall or network topology prevents the client from establishing direct UDP connectivity, RDP continues with a reverse connect transport.

 ## Requirements
 
 To support RDP Shortpath, the Azure Virtual Desktop client needs a direct line of sight to the session host. You can get a direct line of sight by using one of these methods:
 
-- Make sure the remote client machines must be running either Windows 10 or Windows 7 and have the [Windows Desktop client](/windows-server/remote/remote-desktop-services/clients/windowsdesktop) installed. Currently, non-Windows clients aren't supported.

 - Use [ExpressRoute private peering](../expressroute/expressroute-circuit-peerings.md)
 - Use a [Site-to-Site virtual private network (VPN) (IPsec-based)](../vpn-gateway/tutorial-site-to-site-portal.md)
 - Use a [Point-to-Site VPN (IPsec-based)](../vpn-gateway/vpn-gateway-howto-point-to-site-resource-manager-portal.md)
 - Use a [public IP address assignment](../virtual-network/ip-services/virtual-network-public-ip-address.md)
 
-If you're using other VPN types to connect to the Azure, we recommend using a User Datagram Protocol (UDP)-based VPN. While most Transmission Control Protocol (TCP)-based VPN solutions support nested UDP, they add inherited overhead of TCP congestion control, which slows down RDP performance.

 Having a direct line of sight means that the client can connect directly to the session host without being blocked by firewalls.
