PCoIP Client-Side Image Cache
PCoIP client-side image caching stores image content on the client to avoid retransmission. This feature
reduces bandwidth usage.
The PCoIP image cache captures spatial, as well as temporal, redundancy. For example, when you scroll
down through a PDF document, new content appears from the boom of the window and the oldest content
disappears from the top of the window. All the other content remains constant and moves upward. The
PCoIP image cache is capable of detecting this spatial and temporal redundancy.
Because during scrolling, the display information sent to the client device is primarily a sequence of cache
indices, using the image cache saves a signicant amount of bandwidth. This ecient scrolling has benets
both on the LAN and over the WAN.
n
On the LAN, where bandwidth is relatively unconstrained, using client-side image caching delivers
signicant bandwidth savings.
n
Over the WAN, to stay within the available bandwidth constraints, scrolling performance would be
degraded without client-side caching. Over the WAN, client-side caching saves bandwidth and ensure a
smooth, highly responsive scrolling experience.
With client-side caching, the client stores portions of the display that were previously transmied. The cache
size is 250 MB.
