NQE™ Network File Sharing

Brings File Sharing to the Embedded System What is File Sharing?

You are probably using it every day. • Windows Network→Host→Shared Folder→File

“File Sharing”: • Expose your own files • View other’s files Either manually or by program.

2 Confidential What is CIFS/SMB?

CIFS/SMB is a File Sharing protocol which realizes File Sharing functionality. CIFS（Common Internet File System） SMB（） “File Sharing protocol” includes:  CIFS/SMB protocol itself  A series of SMB services which runs over the protocols such as:  RAP(Remote Administration Protocol)  RPC(Remote Procedure Call Services) etc…

3 Confidential Outline of CIFS/SMB history

SMB-1982 Designed by IBM (Barry Feigenbaum)  PC-DOS – 1984  LAN Manager – 1988  Unix and other operating systems (part of the OS or as a suite like ) CIFS- Adopted by as of Win95  Common Internet File System Strictly speaking,  Windows NT 4.0 – 1996 “CIFS” has started  IETF draft – Common Internet File System – 1997 its history from this  SNIA Technical Specification – 1999 year. SMB (returned to the original name) - 2000  Extensions – 2000 So, let’s call the  Extensions for other implementations of SMB oldest SMB as SMB1! SMB 2.0 (or SMB2) – 2008 SMB 2.1 (or SMB2.1) – 2010 Windows 7 SMB 3.x (or SMB3) – 2012 Windows 8

4 Confidential SMB2.x and SMB3.0

Re-designed major SMB versions by Microsoft. Performance improvements

 Much smaller command set ( 75 → 19 )  Improved request compounding (reduced round trips)  Asynchronous operations (Multiple packets sent concurrently)  Larger reads/writes (more data in each packet) Security improvements  SMB Durability provide limited network fault tolerance  Signing – Uses HMAC SHA-256 instead of old MD5

 SMB Encryption Now that IBM cannot interfere Increased file sharing scalability any more.

5 Confidential SMB versions – Who speaks what?

Windows 8 Windows 7 Windows Vista Previous versions Client / Server OS Windows Server Windows Server Windows Server of Windows 2012 2008 R2 2008 Windows 8 Windows Server SMB 3.0 SMB 2.1 SMB 2.0 SMB 1.0 2012 Windows 7 Windows Server SMB 2.1 SMB 2.1 SMB 2.0 SMB 1.0 2008 R2 Windows Vista Windows Server SMB 2.0 SMB 2.0 SMB 2.0 SMB 1.0 2008 Previous versions SMB 1.0 SMB 1.0 SMB 1.0 SMB 1.0 of Windows

6 Confidential SMB – The future of SMB1.0

• Prior to Windows 8.1 SMB1 was an integral part of the OS. • Starting from 8.1 SMB1 is an optional component that may be disabled. It’s still enabled by default. • In the next Windows release We will make SMB1 disabled by default, So that a user will need to turn it on. Not each user knows how to do that. • Later on We are planning to remove SMB1. • We consider the 8.1 case as a "yellow warning" for those that still count on SMB1.

7 Confidential SMB vs. others TFTP, FTP, HTTP  Advantage : The most standard protocol supported by a variety of applications.  Disadvantage : - Pre-installation is required for both of client and server. (and for both of Windows and UNIX) - Configuration is complicated. - File transfer is the main job so downloading/uploading is required for file operations. NFS  Advantage : Seamless linkage with OS. (Depending on each distribution)  Disadvantage : - Not supported by Windows machines ( besides Windows server )  - Configuration is complicated. SMB  Advantage : Windows standard protocol - Seamless mechanism with OS. - Can be used even in UNIX machines by using SMB. - Easy Configuration. - Direct “open” and “modification” is allowed because of its nature of “File Sharing protocol”. - Temporary area is not needed.  Disadvantage : Installation of Samba is required for UNIX machines.
