[Microsoft Home][Products][Search][Support][Shop][Write Us] [Microsoft Home] New Features Description ROUTING PROTOCOLS RIP v2 (and v1) Routing Information Protocol is a frequently for IP used routing protocol for small to mid-sized networks. It is relatively easy to use and provides very good performance. The service supports both version 1 and version 2 of RIP. OSPF Open Shortest Path First is a link state routing protocol used for routing IP, OSPF is a more sophisticated routing protocol than RIP and is primarily used in larger enterprise networks. OSPF offers faster routing algorithm convergence. The service's OSPF implementation is a result of collaborative effort between Microsoft and Bay Networks, a leading provider of internetworking systems. DHCP Relay Agent Dynamic Host Configuration Protocol (DHCP) for IP provides lower cost of ownership for IP networks because it dynamically assigns IP addresses to PCs or other resources connected to an IP network. This is a dramatic improvement in time and dollar savings compared to manually assigning useable IP addresses. The service provides a relay agent function for DHCP servers so that DHCP assignments can be made across routed networks regardless of whether the connection is made via LAN or WAN (Wide Area Network) links. RIP and SAP for Routing Information Protocol (RIP) and Service IPX Advertising Protocol (SAP) are two routing protocols commonly used in Novell Netware (IPX) small- to mid-size network environments. The service supports these routing protocols to enable interoperability in mixed network environments. Static Routing The service continues to support use of static, or fixed, routing assignments. EXTENSIBILITY WHICH MAKES THE SERVICE A PLATFORM Routing APIs The service supports a defined interface to enable third party companies to write additional routing protocols for use with the service In fact, the routing protocols included with the service were written to these same routing protocol APIs. Microsoft offers a Software Developer Kit (SDK) that describes for developers how to use these APIs. This is a unique feature enabling Windows NT Server with this service to be a platform for value-added development in routing and internetworking. It also provides customers great flexibility and investment protection. Management and The service supports an intuitive graphical User Interface user interface and command-line user interface APIs for administrators. This manageability is extensible. This feature enables a PC running the service to be managed as though it were a router made by another manufacturer. This enables the service to work well in legacy environments and makes it easier and less expensive to begin using the service in a variety of networks. The service supports SNMP MIB II so the service can be managed from an SNMP console. The service also supports proprietary management functions. The service's GUI and command-line controls are written to these same management APIs. EASE OF USE Graphical User The service provides a comprehensive, intuitive Interface graphical user interface which provides a wide range of monitoring and administrative functions for all routes, LAN or WAN interfaces, packet filtering features, and more. The service supports administrative screens that are consistent with other standard Windows GUI approaches, including support for right clicking on the mouse for additional control and a setup wizard. Scriptable, Many network managers are more comfortable Command Line User using a command-line interface to manage their Interface network infrastructure. The service supports command-line interface control, including support for scripting. Remote The service's GUI controls and command-line Manageability controls are remote-able to enable enterprise network management from a central location, remote site, or from mobile workstations. The service's GUI controls are remote-able via Remote Procedure Calls. The service's command-line controls are remote-able via telnet. RAS Restartable This feature automatically begins File Copy re-transferring a file upon re-connection whenever your RAS connection has been lost. Nearly anyone who has used a modem can probably remember times when they've nearly completed a file transfer across a modem only to have their remote connection disabled before the transmission was completed. Re-establishing the connection and starting the file transfer process all over again can be frustrating, time-consuming, and expensive. Re-startable file copy addresses these problems by remembering the status of your file transmission and continuing the transfer from that point once you re-connect. This is a feature included with RAS in Windows NT Server 4.0 and Windows NT Workstation 4.0 and is retained in this new service. RAS Auto-dial and The Windows oprerating system can map and Auto Log-On Dial maintain an association between a Dial-Up Networking entry and a network address to seamlessly integrate Dial-Up Networking with files and applications. This means if you double-click on an icon to open a file and if that file is only accessible over the dial-up connection, Dial-Up Networking will automatically initiate the call. This is a Windows NT 4.0 feature that is retained in the new service. IMPORTANT COST-SAVING FEATURES Available at no This new service is available to Windows NT additional charge Server 4.0 customers via web download at no additional charge, making server-integrated routing and remote access with Windows NT Server uniquely affordable. Demand Dial The new service supports on-demand dialing over Routing any variety of WAN links, including via the Internet with Point-to-Point Tunneling, eliminating the need for continuous, "nailed-up" connections. As a result, demand dial provides significant cost-savings. Point-to-Point The service includes support for award-winning Tunneling - technology first introduced in Windows NT Client-to-Server Server 4.0 and Windows NT Workstation 4.0 - Point-to-Point Tunneling. Point-to-Point Tunneling provides a way to use public data networks, such as the Internet, to create a virtual private network connecting remote client PCs with servers. PPTP encapsulates multiple protocols (IP, IPX, NetBUI) via TCP/IP connections and allows data encryption for privacy, making it safer to send information over non-secure networks. This technology allows you to securely extend private networks across the Internet without the need to change the client software. As this is written, PPTP client support is also available now for Windows 95, Macintosh, and Windows 3.1. Point-to-Point The service extends the Point-to-Point Tunneling Tunneling support offered initially in Windows Support: NT 4.0 by enabling remote servers - not just Server-to-Server remote clients - to connect using a secure, encrypted tunnel. This important feature enables branch offices to be connected to a corporate network via the Internet rather than via more expensive leased line arrangements. This new use of the Internet as a Virtual Private Network can provide big cost savings compared to traditional WAN link alternatives. Works with Because this is a service that runs on Windows Industry Standard NT Server 4.0, it can enable routing using any LAN & WAN Cards of the 2,000+ LAN and WAN cards that have earned the Windows NT Compatible logo. This provides unbeaten customer choice. Now customers, for the first time, can take advantage of PC industry economics for routing and internetworking. Microsoft Microsoft Point-to-Point Compression (MPPC) Point-to-Point lets an organization make the most use of WAN Compression links for remote access or routing. MPPC supports compression of up to about 4:1 -compression performance varies by the type of date being transmitted over the link. MPPC is available for third party licensing. RAS Idle This feature automatically terminates your RAS Disconnect connection after a certain period of time if there has been no activity over the remote dial-up communications link. The user or administrator can specify the amount of time before this feature is activated. This is a Windows NT 4.0 feature that is retained in the new service. SECURITY & MANAGEABILITY IP packet The service supports a variety of inbound and filtering outbound packet filtering features. These packet filtering features provide an important measure of network security. Here is a list of filtering options: TCP Port, UDP port, IP protocol ID, ICMP type, ICMP code, source address, destination address. IPX packet The service supports a similar level of packet filtering filtering for IPX packets. Here is a list of IPX packet filter options: source address, source node, source socket, destination address, destination node, destination socket, and packet type. RADIUS client - Now a server PC running Windows NT Server and RFC 2058 this new service can act as a RADIUS client to compliant a RADIUS server, providing expanded customer choice for authentication and user accouting. RADIUS (Remote Authent-ication Dial-In User Service) is a distributed security solution with widespread, growing adoption in the industry for use in enterprise and in public carrier networks. This is one of the latest features added to the service Complements use The service can be used with Microsoft Proxy with Microsoft Server to provide an even higher level of Proxy Server network security and performance. Microsoft Proxy Server reduces network costs and bandwidth needs by caching Internet or Intranet sites. Microsoft Proxy Server lets network administrators control what Internet or Intranet services their users can access and provides application layer security, complementing the service’s packet layer security. Authentication, The new service inherits all the features that Encryption, and make Windows NT Server RAS a secure, scalable more in Windows platform for remote access. NT Server RAS PERFORMANCE Great router The service is targeted to provide packet performance at forwarding rates in excess of 30,000 packets low-end router per second in regular use. This means the pricing service can be used in many routing situations. [Microsoft Internet Explorer] [Image] [Image] [Image] [Products] © 1997 Microsoft Corporation. All rights reserved. Terms of Use.
