What is remote node access?
Remote node network access allows remote users to connect to a network using a modem. Remote node users are typically mobile or telecommuter users who run a remote client software package on their PC or workstation giving them network access through a dial-up server. Remote node access to the network has become easier because of the TCP/IP or IPX support that's been built into Windows95 and other operating systems. Most of the current demand for such services involves either IP (Unix) or IPX (Novell NetWare) protocols.
Why is modem pooling important?
For the network manager, modem pooling provides the added conveniences of easy maintenance because all modems are in one location, and easy management as remote access servers typically have more robust network management than modems. Protocols such as IP and IPX support the sharing of modem resources through software tools available under a host or network operating system ( the remote access device that supports these applications provides ever greater value. INT14 support under IPX and redirection of serial port output to a communications port using IP and IPX protocols are essential features that this type of software should support.
Why is remote control important?
Remote control is useful when a user needs a lot of processing power or number crunching capability, because only the serial information sent to the keyboard, mouse and display need pass over the dial-up link. The drawback of this approach is that the user can only view the information and cannot transfer files or obtain data to be processed on their remote system. Remote control is more frequently used with the IPX (NetWare) protocol; IP users can use terminal servers to achieve the same result when a multi-user host is available.
