While several vendors had already added support for NFS Version 2 with TCP as a transport, Sun Microsystems added support for TCP as a transport for NFS at the same time it added support for Version 3. At the time of introduction of Version 3, vendor support for TCP as a transport-layer protocol began increasing. This became an acute pain point for Digital Equipment Corporation with the introduction of a 64-bit version of Ultrix to support their newly released 64-bit RISC processor, the Alpha 21064.
By July 1992, implementation practice had solved many shortcomings of NFS Version 2, leaving only lack of large file support (64-bit file sizes and offsets) a pressing issue. The principal motivation was an attempt to mitigate the performance issue of the synchronous write operation in NFS Version 2. The first NFS Version 3 proposal within Sun Microsystems was created not long after the release of NFS Version 2. a READDIRPLUS operation, to get file handles and attributes along with file names when scanning a directory.additional file attributes in many replies, to avoid the need to re-fetch them.
support for asynchronous writes on the server, to improve write performance.support for 64-bit file sizes and offsets, to handle files larger than 2 gigabytes (GB).NFSv2 only allows the first 2 GB of a file to be read due to 32-bit limitations. By February 1986, implementations were demonstrated for operating systems such as System V release 2, DOS, and VAX/VMS using Eunice. The Virtual File System interface allows a modular implementation, reflected in a simple protocol. People involved in the creation of NFS version 2 include Russel Sandberg, Bob Lyon, Bill Joy, Steve Kleiman, and others. Its designers meant to keep the server side stateless, with locking (for example) implemented outside of the core protocol. Version 2 of the protocol (defined in RFC 1094, March 1989) originally operated only over User Datagram Protocol (UDP). This protocol uses 139 and 445 TCP ports and 137 and 138 UDP ports.This section needs expansion. This protocol uses 111 port for both TCP and UDP.ĩ. This protocol is easy to implement and set up.ĩ.

NETWORK FILE SHARING PROTOCOLS MAC
This protocol is used with Apple Mac OS, Unix, and Unix-like operating systems such as Solaris, Linux, FreeBSD, AIX. It is implemented in that client/server application in which the server of NFS manages the authorization, authentication, and clients.
Network File System is a protocol that works on all the networks of IP-based. It uses the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) for accessing and delivering the data and files. This protocol is mainly implemented on those computing environments where the centralized management of resources and data is critical. This protocol is also built on the ONC RPC system. Any user can manipulate files as same as if they were on like other protocols. Any user can easily implement the NFS protocol because it is an open standard. It is that protocol which allows the users to access the data and files remotely over the network. It is an architecture of the client/server, which contains a client program, server program, and a protocol that helps for communication between the client and server. This protocol was developed by the Sun Microsystems in the year of 1984. It is a protocol of a distributed file system. NFS is an abbreviation of the Network File System.
