Priorities are assigned to network traffic across multiple connections for a session with quality of service (QoS)-supported routers. Four TCP/IP streams (real-time, interactive, background, and bulk) and one UDP/RTP stream (for voice) are available to carry ICA traffic between the user device and the server. Each virtual channel is associated with a specific priority and transported in the corresponding connection. You can set the channels independently, based on the TCP port number used for the connection.
Multiple channel streaming connections are supported for Virtual Delivery Agents (VDAs) installed on Windows 8 and Windows 7 machines. Work with your network administrator to ensure the Common Gateway Protocol (CGP) ports configured in the Multi-Port Policy setting are assigned correctly on the network routers.
Quality of service (QoS) is supported only when multiple session reliability ports, or the CGP ports, are configured.
Explicitly configure the firewalls on VDAs to allow the additional TCP traffic.
For policies containing these settings to take effect, users must log off and then log on to the network.
