Network Considerations

In a PCoIP system, only the display and peripheral data leaves the corporate datacenter to the local user

network. This changes the resource profile required compared to the traditional model of PCs and workstations

located at the user's desk.

PCoIP Technology Networking Capability Summary:

•

PCoIP host and portal are IPv4 based (IPv6 capable) with static or DHCP IP assignment

•

PCoIP host/portal devices have integrated 10/100/1000 Ethernet.

•

All PCoIP traffic is fully protected with IPSEC using wire-speed, hardware accelerated 128-bit AES

encryption and authentication.

•

PCoIP traffic is primarily point-to-point between host and the peer portal with the bandwidth typically

dominated by downstream host-to-portal traffic

•

PCoIP downstream bandwidth is determined primarily by user profile and screen resolution. Only

screen changes are transferred so that a static display requires virtually no downstream network

bandwidth.

•

Upstream traffic from portal to host is dominated by USB input data.

•

Progressive build is used to deliver an exact image of the rendered host PC display with a minimal

network loading. Progressive build increases system responsiveness by quickly delivering an initial

image to the desktop while still supporting a fully lossless display image transfer.

•

The total network bandwidth used is automatically adjusted by PCoIP host and portal devices by

dynamically changing the compression ratios used. Users can select their preference for image quality

or image responsiveness.

•

Integrated traffic shaping allows source bandwidth metering and supports a hard device bandwidth limit

setting.

Figure 3 shows an example PCoIP deployment, and the flow of user and datacenter network traffic. PCoIP

technology can off-load corporate networks by containing a number of traffic types to the corporate datacenter.

These include:

•

file transfers between PCs and servers

•

database transactions

•

Internet data transfers
