Here is an informal performance comparison for some of these IO methods. Note For examples that use the StringIO class, make sure you import it according to your Python version, i. They both use the same parsing code to intelligently convert tabular data into a DataFrame object.

The SMB "Inter-Process Communication" IPC system provides named pipes and was one of the first inter-process mechanisms commonly available to programmers that provides a means for services to inherit the authentication carried out when a client[ clarification needed ] first connects to an SMB server.

The most common official term is "SMB signing". The default setting from Windows 98 and upwards is to opportunistically sign outgoing connections whenever the server also supports this, and to fall back to unsigned SMB if both partners allow this.

The default setting for Windows domain controllers from Windows Server and upwards is to not allow fall back for incoming connections. This protects from man-in-the-middle attacks against the Clients retrieving their policies from domain controllers at login.

SMB supports opportunistic locking —a special type of locking-mechanism—on files in order to improve performance. Microsoft submitted some partial specifications as Internet-Drafts to the IETF[14] though these submissions have expired.

It adds the ability to compound multiple actions into a single request, which significantly reduces the number of round-trips the client needs to make to the server, improving performance as a result.

SMB2 includes support for symbolic links. Other improvements include caching of file properties, improved message signing with HMAC SHA hashing algorithm and better scalability by increasing the number of users, shares and open files per server among others.

SMB2 uses 32 or bit wide storage fields, and bits in the case of file-handlesthereby removing previous constraints on block sizes, which improves performance with large file transfers over fast networks.

SMB2 is also a relatively clean break with the past. SMB1 features many versions of information for commands selecting what structure to return for a particular request because features such as Unicode support were retro-fitted at a later date.

SMB2 involves significantly reduced compatibility-testing for implementers of the protocol. SMB2 code has considerably less complexity since far less variability exists for example, non-Unicode code paths become redundant as SMB2 requires Unicode support.

Client-server approach[ edit ] SMB works through a client-server approach, where a client makes specific requests and the server responds accordingly. One section of the SMB protocol specifically deals with access to filesystemssuch that clients may make requests to a file server ; but some other sections of the SMB protocol specialize in inter-process communication IPC.


This virtual share is used to facilitate communication between processes and computers over SMB, often to exchange data between computers that have been authenticated. Developers have optimized the SMB protocol for local subnet usage, but users have also put SMB to work to access different subnets across the Internet— exploits involving file-sharing or print-sharing in MS Windows environments usually focus on such usage.

SMB servers make their file systems and other resources available to clients on the network. Client computers may want access to the shared file systems and printers on the server, and in this primary functionality SMB has become best-known and most heavily used.

However, the SMB file-server aspect would count for little without the NT domains suite of protocols, which provide NT-style domain-based authentication at the very least.

Samba software This section needs to be updated. Please update this article to reflect recent events or newly available information. As of version 3Samba provides file and print services for Microsoft Windows clients and can integrate with a Windows NT 4.

Samba4 installations can act as an Active Directory domain controller or member server, at Windows domain and forest functional levels. It supports only SMB 2. The platform could be used for traditional NAS, Cloud Gateway, and Cloud Caching devices for providing secure access to files across a network.

Likewise was purchased by EMC Isilon in It has the following advantages over user-space implementations: It provides better performance, and it's easier to implement some features like SMB Direct. It supports SMB 3. Performance issues[ edit ] The use of the SMB protocol has often correlated with a significant increase in broadcast traffic on a network.

NetBIOS functions by broadcasting services available on a particular host at regular intervals.In computer networking, Server Message Block (SMB), one version of which was also known as Common Internet File System (CIFS, / s ɪ f s /), operates as an application-layer network protocol mainly used for providing shared access to files, printers, and serial ports and miscellaneous communications between nodes on a network.
