What is dial up remote access?
Dial-up remote access requires only plain old telephone service (POTS) or ISDN lines, and allows users to make connections to many resources, from corporate headquarters, to bulletin board services, to the Internet/Intranet. Dial-up remote access also allows travelling or telecommuting remote users to connect to their network as if they were located on-site.
What is dial up connection?
A dial-up connection between two networks is termed as an LAN-to-LAN connection . In most cases, remote office locations will connect to a main corporate network at a central location. In other cases, one small office may connect to another small office or to a site where services such as Internet access or information services are provided.
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.
What is the key attribute of remote access?
No matter what remote access strategy you plan to implement, one key attribute that requires the greatest attention, is that of providing controlled access to your important/proprietary data. When a strategy for networking involves dial-up technology, issues of network security become very important. Each modem is a potential gateway for uninvited users, either by chance or malicious intent, to gain access to the attached network.
What is routing in network?
When a connection is made to another network, routing is the key to this type of functionality ( when a user on the network requests connection to a resource available only on another network, the remote access device recognises the need to dial another network and then automatically dials up the appropriate remote site according to a stored profile. Once the connection has been established, the remote access device will monitor the connection according to the parameters established by the network manager.

PPP utilizes the Link Control Protocol (LCP), which tests the link between client and PPP host and specifies PPP client configuration, to communicate between host and PPP client. LCP allows PPP to support authentication negotiation, in addition to compression and encryption negotiation between the client and the server, using encryption control protocols (ECPs) and compression control protocols (CCPs). PPP can support multiple network protocols by using protocol-specific network control protocols (NPCs). Because it can run over numerous physical media types and features error-checking functionalities, PPP has almost entirely replaced SLIP.

Dial-up involves one modem connecting with another over the Public Switched Telephone Network (PSTN), creating a temporary, dedicated WAN link. There are three possible protocols for making the initial connection: Point-to-Point Protocol (PPP), Serial Line Internet Protocol (SLIP), and Asynchronous NetBEUI (AsyBEUI). Table A explains their differences.
What is virtual private network?
Virtual private networking protocols encapsulate PPP frames (the data units at the data link layer of the OSI model) into IP datagrams at the network layer. These datagrams are then sent across an internetwork, which can be either a private network or, more commonly, the Internet. This encapsulation creates a “tunnel” that acts like a dedicated WAN link, even though it usually uses the Internet—thus, a “virtual” private network.
Why do you want to be encrypted in a remote session?
First, you want the best security you can provide for the remote session. You want authentication to be encrypted so that someone who is snooping cannot see it , and you want the data that is passed in the remote session to be encrypted for the same reason. Second, older systems and their associated protocols are less capable in terms ...
