Chapter 4. What's New and Noteworthy in ... > Communications and Networking

Communications and Networking

The Internet may be all the rage, but most corporate administrators are more interested in keeping their local area networks (LANs) running smoothly, improving remote access to their LANs, extending those LANs to their customers, and implementing higher-speed technologies. The communications gurus at Microsoft are aware of this, of course, so they included in Windows 98 many new communications and networking features:

Dial-Up Networking enhancements: Windows 98 incorporates several new Dial-Up Networking features, including an improved properties sheet, hands-free dial-up, support for scripting, and the ability to set up a Windows 98 machine as a dial-up server. I cover all of this in Chapter 30, “Remote Computing with Dial-Up Networking.”

ISDN 1.1 Accelerator pack: Windows 98 bundles the ISDN Accelerator pack, which enables Dial-Up Networking to work with an ISDN adapter card.

Virtual Private Networking and PPTP: Windows 98 supports the Point-to-Point Tunneling Protocol (PPTP), which enables you to establish an extended private network (called a Virtual Private Network) over a public network such as the Internet. See Chapter 30 to get the full details.

Multilink Bandwidth Aggregation: This is a communications feature that enables Windows 98 to combine the bandwidth from multiple lines into a single, larger pipe.

TCP/IP improvements: The Windows 98 TCP/IP stack boasts a number of enhancements, including support for Autonet Addressing, TCP large windows, Selective Acknowledgements, Fast Retransmission, and Fast Recovery. I give you an overview of TCP/IP concepts and implementation in Chapter 31, “Implementing TCP/IP for Internet and Intranet Connections.”

Windows Sockets (WinSock) 2: This is an update to the WinSock 1.1 support found in Windows 95. WinSock 2 implements a protocol-independent interface, which means it can work with protocols other than TCP/IP. It also utilizes protocol-independent name resolution, so it works not only with DNS, but also with domains such as SAP and X.500.

Resource ReSerVation Protocol (RSVP): This is a new networking protocol that Microsoft has proposed as an Internet standard. It's used to guarantee a particular level of transmission service by reserving in advance the network resources required by the transmission.

New modem support: The Windows 98 Unimodem driver implements support for VoiceView modems, controllerless modems, and Sierra modems. See Chapter 26, “Getting Started with Modem Communications.”

Updated telephony support: Windows 98 supports the new TAPI 2.1 telephony standard.

Distributed Common Object Model (DCOM): DCOM extends the Common Object Model (see Chapter 19, “Sharing Data in Windows 98: The Clipboard and OLE”) so that component-based applications can communicate across a network.

Novell NetWare 4.x client: Windows 98 includes the full client for NetWare 4.x, including client support NetWare Directory Services. See Chapter 28, “Setting Up Windows 98 for Networking.”

NDIS 5 and ATM support: Windows 98 supports the NDIS 5 network interface, which means Windows 98 can work with Asynchronous Transfer Mode (ATM) network adapters, as well as LAN Emulation (LANE) over ATM.

32-bit Data Link Control (DLC): Windows 98 includes the 32-bit DLC protocol for accessing IBM mainframe and AS/400 computers. Although I don't discuss the DLC protocol in this book, I show you how to install network protocols in Chapter 28.
