Determine Per-User Planning Bandwidth Use the table below to determine the planning bandwidth per user. If a user has more than one display, use the column for the largest display. Table 2: User Category Planning Bandwidth Guidelines Display Resolution vs Planning Bandwidth Table User category 1024x768 Task Worker1 3 Mbps Knowledge Worker/Basic CAD Performance User / 3D Modeling 10 Mbps 30 Mbps Video Editing - Extreme Bandwidth Allocation - 1280x1024 1680x1050 1600x1200 1920x1200 5 Mbps 7 Mbps 6 Mbps - 15 Mbps 20 Mbps 22 Mbps 25 Mbps 45 Mbps 60 Mbps 65 Mbps 80 Mbps 60 Mbps 80 Mbps 85 Mbps 100 Mbps 120 Mbps 160 Mbps 170 Mbps 200 Mbps Determine the Link Planning Bandwidth Conservatively, the network should be sized such that, when all users are active, each PCoIP connection is able to achieve the planning bandwidth allocated for each user. The planning bandwidth is the measure of the minimum quality a user will accept and feel they are receiving a true PC experience. For each link in the network, the network capacity required for a PCoIP implementation is calculated by summing the planning bandwidths of all the users sharing that network link, and adding 10% to allow for variations in the traffic profile and to ensure fair sharing of the network resources across multiple PCoIP Host/Portal pairs. Set the Device Bandwidth Target The Teradici PCoIP system provides an optional Device Bandwidth Target parameter to enable fair bandwidth sharing between many users sharing a constricted link. It is recommended to set the Device Bandwidth Target parameter on the PCoIP host to the planning bandwidth for the user. Example Deployment Scenario The following example deployment scenario illustrates the ability to fit Teradici's PCoIP technology within existing enterprise network infrastructure. Specifically, this example walks through the deployment of 190 users that are segmented into 48 task workers, 120 knowledge workers and 10 performance users within an existing switched enterprise network. Table 3: Example Bandwidth Determination per User Category Task Worker (48 users) Knowledge Worker (120 users) Performance User (10 users) Single display 1024x768 3 Mbps Planning Bandwidth (Table 2) Dual display 1280x1024 15 Mbps Planning Bandwidth (Table 2) Dual display 1680x1050 (wide screen) 60 Mbps Planning Bandwidth (Table 2) 1 The task worker planning bandwidth estimates, in contrast to the estimates for the other user categories, do not include an allocation for audio streams. If the IT administrator determines audio allocation is required for task workers, increase the task worker planning bandwidth by 0.85Mbps. TER0806005 Issue 1 8
