Microsoft recently announced H.265 video codec support for the Remote Desktop Protocol (RDP) protocol used in its Azure Virtual Desktop (AVD) product, which allows raw media to be compressed into a more efficient format when being streamed. While this is a positive development for users, the RDP protocol still lags behind Citrix and Other's HDX and Blast protocols in terms of customization and bandwidth adjustments.
Microsoft's RDP protocol sees little innovation compared to Citrix and Other protocols HDX and Blast.
Shortpath using UDP/3390 is an improvement in the RDP protocol but has been part of RDS using Gateway for a while.
Microsoft has released little news regarding the RDP protocol specification, with only support for newer Windows versions and integration with Entra ID.
Although the protocol has little customization compared to HDX and Blast, Microsoft has recently introduced H.265 support for the RDP protocol in its Azure Virtual Desktop (AVD) product.
H.265 support is not a game-changer, as both Citrix and Others already support AV1, a newer protocol than H.265.
Microsoft now needs to invest more in the RDP protocol stack and improve it for high-latency and high-packet loss scenarios.
The RDP protocol is in need of better throughput where high bandwidth connections are available.
Support for AV1 codec in RDP protocol is essential to keep up with the market.
H.265 support is only available for specific virtual machines and configuring H.265 can only be done using group policy at the moment.
