If, on the other hand, you're in a bandwidth-constrained environment, you may need a more efficient protocol. Bear in mind that the more bandwidth-efficient the protocol, the more CPU or graphics processing unit (GPU) cycles it will likely require at the host to compress information. There is always a tradeoff. A number of protocols are available to you, depending on which VDI solution you choose: » RDP: Assuming that most VDI environments are based on Windows, RDP is the default protocol and is available regardless of whether you go with Citrix or VMware. It's the lowest common denominator, but it's still good for many users. » PCoIP: Developed by Teradici and licensed by VMware, PC-over-IP was the solution to solve the need for an efficient protocol that also provided a closer-to-native experience for end-users. PCoIP provides an encrypted experience with granular bandwidth controls, support for 32-bit color, audio redirection, real-time audio/video, multiple monitor support, shared clipboard, and USB redirection. PCoIP is a lossless protocol that perfectly replicates the desktop environment. » VMware Blast Extreme: In Horizon 7, VMware introduced Blast Extreme, an H.264-based protocol that requires less bandwidth than PCoIP, making it more suitable for mobile devices. Blast Extreme works well and can leverage servers that have been equipped with GPUs for 3D work. Blast Extreme is based on a video codec that includes compres- sion, so the image displayed on the endpoint may not be a perfect match for what's on the host. It provides a number of benefits, including bandwidth friendliness, GPU support, lower CPU consumption, multi-monitor support, and hardware decoding. » Citrix HDX: Citrix has done well over the years with HDX, its high-fidelity, bandwidth-friendly VDI client. HDX, like PCoIP, aims to replicate, as closely as possible, a native-quality user experience in a virtualized environment. HDX also provides multi-monitor support, as well as support for 3D graphics and GPU acceleration.
