- FOLDER SYNC APP SMBV3 UPDATE
- FOLDER SYNC APP SMBV3 WINDOWS 10
Spoiler alert: a user probably can’t tell anything changed except that SMB now works when I’m at a hotel for Microsoft Ignite. Here’s a quick (heh) demo of the user experience. All seamless to the end user and their apps. And if they are travelling or an admin mandates QUIC, they can get that instead. This means if they can get faster perf on a local network with RDMA or unencrypted TCP, they will.

So, we don’t add extra UI or command-line arguments to the client experience – their updated Windows 10 machines will simply try TCP and RDMA like always, but then wait briefly and try QUIC too.
Simple: The user experience for SMB over QUIC can’t change from their corpnet/LAN/branch office experience, it’s too expensive to retrain users. The entire SMB conversation – negotiate capabilities, authentication, authorization, message bodies – all occur inside the QUIC layer, just like if the user was in an IPSEC or VPN tunnel. Secure: Prevent man-in-the-middle and spoofing by malicious parties as well as guarantee no sniffing of that sweet file payload or allowing any user credentials onto the Internet. We have two design imperatives for SMB over QUIC: Or enable it on their Azure Files instance. An admin will be able to opt- in to this new capability by deploying a Windows Server at the edge of the network, installing a certificate trusted by clients, then enabling the QUIC option. With SMB over QUIC – I don’t have a clever marketing name for this yet :) – QUIC becomes the transport, optionally replacing TCP/IP and RDMA, as well as a tunnel securing all SMB payloads with encryption, even if SMB encryption is not enabled, all while multiplexing over port 443 to an enlightened share. QUIC’s already in use in Windows 10 through the Edge browser and other apps. Unlike TCP, QUIC is always encrypted and requires TLS 1.3 with certificate authentication of the tunnel. QUIC is an IETF-standardized protocol that replaces TCP with a web-oriented UDP mechanism that theoretically improves performance and congestion, but still tries to maintain TCP’s reliability & broad applicability. Even though users are just as likely to be deskless and organizations are doing more hybrid computing than ever, SMB hasn’t kept up. Departments trying to use Azure Files often find their ISP has blocked port 445. In today’s world, SMB file share access for mobile users requires expensive & complex VPNs. 
Hi folks, Ned Pyle guest-posting today about SMB over QUIC, a game-changer coming to Windows, Windows Server, and Azure Files.
