three kinds of networking
Summary of LAN Server
LAN Server is a network operating system based on OS / 2 from IBM.
LAN Server file servers grouped by domains.
LAN Access Server delivers improved data bases.
LAN Server is preferred over other NOS to those customers who have invested heavily in mainframe computers.
Access to resources can be done by their nicknames or aliases.
Banyan VINES Virtual Networking System System (virtual network)
(Vines, formerly an acronym and is now a registered trademark) of Banyan Systems, a network operating system based on a version Modified UNIX. VINES represents the highest standard interredes connectivity and security and transparency of operation. The company offers various accessory products, including e-mail software and network management.
VINES supports a wide range of hardware architectures including the IBM Token Ring, SMC ARCnet, Ethernet Interlan, EtherLink and EtherLink Plus 3Com, Proteon ProNet-10.Requires a dedicated file server. All VINES services, including naming, file, print and mail processes running as UNIX. These services can be started and stopped from the server without disturb other services. Although for some time, industry experts have extolled the capabilities of multiple tasks and UNIX users also indicated that it hinders their acceptance by a large segment of the general public because it lacks a friendly user interface. While the user interface VINES is a menu system and VINES is based on UNIX, the user must exit this network environment before you can use UNIX.
VINES version 6.0 offers support for clients running DOS, Windows, Windows 95, OS / 2, Macintosh and a variety of UNIX clients.VINES 6.0 server can communicate with clients that support the following protocols: VINES / IP, IPX, IP, AppleTalk, and NetBIOS. StreetTalk is the distributed database VINES and acts as a naming service resources. Resources can represent users, services (such as printers, volumes, files or gates), and even lists. With StreetTalk and VINES, a user need not know the path or location of users (or other resources). To further facilitate things, StreetTalk allows creating aliases or nicknames for users.
The various VINES file servers communicate and exchange information StreetTalk, using what is known as bursts out. These communications occur whenever a user joins the network, when the administrator adds or removes information or service group and every 12 hours from the time the last server went online. In version III StreetTalk, Banyan added new management capabilities. Now network administrators can rename users and groups move through the network. This approach is much higher than the previous method of removing users and lists and then re-enter with new names and profiles. Administration Banyan VINES network provides network management software that provides statistics LAN and LAN interface, and detailed information about the servers, disk activity and the overall network performance.
This software, designed as a network diagnostic tool, provides information for network administrators about the size of the file server’s cache, the cache hit rate, the number of times the file system was not available and signs vital overall performance, the number of messages sent and received, the number of messages discarded and the average number of exchanges. In addition, network managers can observe the activities of multiple servers simultaneously. VINES offers different levels of security. A network administrator may require the use of a password to log into the network. You can also specify the hours and days on which a particular user can register on the network. In VINES printers PC linked to the network can be shared as linked directly to the file server. This eliminates the limitation related to the distance between printer and server and makes the location of the printer is much more flexible operation.
The network administrator determines which printers are available to certain users by assigning a virtual connection for each print queue listed in a user profile. VINES gates to other networks VINES The main strength lies in its ability to provide transparent access to network resources regardless of their location or the protocol they use. The routing software TCP / IP Banyan allows a PC user to access the resources TCP / IP, whether they reside on a local network or wide area network without having to worry about these physical details. VINES Option for Macintosh supports an unlimited number of Macintosh clients through a Banyan network. A Macintosh workstation located anywhere VINES network can access resources anywhere residing on the network.The VINES software for Macintosh is compatible with AppleTalk Filing Protocol. Banyan VINES future plans to make VINES can run on additional platforms. The company plans to add support for UNIX and Windows NT clients, improved email capabilities and offer new services VINES system level.
