The North American standard provides 23 B-channels plus one D-channel. Software Features Nautica Routing Services (NauticaRS) NauticaRS software enables the Nautica 4000 to maximize connectivity by supporting standards-based protocol features and services (see Table 1). NauticaRS Protocol Implementations NauticaRS software provides a comprehensive set of standards-based IP, IPX, Frame Relay, and PPP features and services. IP NauticaRS ensures highly-reliable, standards-based connectivity and interoperability through standard IP functions and support for major Internet Engineering Task Force (IETF) Request for Comments (RFCs) for protocols including IP,TCP, Routing Information Protocol (RIP),Address Resolution Protocol (ARP), Internet Control Message Protocol (ICMP), User Datagram Protocol (UDP), Dynamic Host Configuration Protocol (DHCP), Bootstrap Protocol (BootP) Relay, Dynamic RIP routing, and static routes. This range of support ensures users highly reliable, standardsbased connectivity and interoperability. The DHCP and BootP Relay Mode in NauticaRS allow corporations and service providers increased choice and flexibility for determining and implementing their IP Address allocation strategy. DHCP gives a framework for passing configuration information to IP hosts connecting to a network, as defined under RFC1541. BootP Relay Mode passes IP address requests and delivers host-specific configuration parameters from a centrally located DHCP server to a DHCP client. The Nautica 4000 can be configured to function as a local DHCP server for workstations connected directly to the local Ethernet segment. A Nautica 4000 functioning as a DHCP server provides IP addresses dynamically to workstations as they appear on the LAN. This eases IP configuration and reduces costs by eliminating the need for workstations to dial up an ISDN session to get their IP address. Nautica 4000’s IP implementation increases network security and reduces overhead traffic through its IP RIP Direction Control feature. This feature controls the flow of broadcast traffic over the network. Broadcast traffic generated by IP RIP can be configured as send only, receive only, both, or neither on a per-path basis. IPX The NauticaRS’s IPX implementation supports Link Service Access Point /Logical Link Control 2 (LSAP/LLC2), IPX over Ethernet Type II, and Novell proprietary protocol. RIP routing is also supported to ensure that the best path to a destination is used. The Nautica 4000’s IPX implementation provides increased network security and reduced overhead traffic through the IPX Default Route feature, Service Access Point (SAP) Direction Control, and Sequenced Packet Exchange (SPX) spoofing. Network Address Translation (NAT) NAT is a method for translating an internal IP address or network into a globally unique IP address. NauticaRS’s support of NAT simplifies management, configuration tasks, and saves addresses by enabling service providers to assign a Nautica 4000 an IP address without requiring any reconfiguration of the network behind the router. NAT can be used on a Nautica 4000 in the following three ways: • • • NAT with a Single PC. This is a single PC connected to a Nautica 4000 that is connected to an Internet provider. The Nautica 4000 is provided with the IP address by the remote router. The Nautica 4000 translates between the PC’s IP address and the supplied IP address. NAT Many to One. All devices on the internal network are configured with internal addresses. The Nautica 4000 translates between these addresses and a single external address. NAT with Multiple Remote Routers. Each remote router provides the Nautica 4000 with a different IP address. The router translates between the different addresses depending on the path used. Additionally, IP filtering can be used in conjunction with NAT to prevent internal users from gaining access to specified external resources, enhancing security. Single IP (SIP) Addressing Support for this feature provides cost-effective Internet access by allowing users on a small LAN to only purchase a single IP address from their Internet Service Provider (ISP). SIP addressing support also simplifies the administration of remote users because one IP address pertains to all users. The Nautica series NAT implementation works in conjunction with SIP such that all internal IP addresses are mapped to a single, legal, external IP address. The Nautica 4000 automatically translates between the internal and external IP addresses and determines for which particular host the incoming data is destined.

This capability is referred to as BootP Relay mode. PPP and MP Industry-standard PPP and RFC 1990 — MP are supported for multivendor interoperability over ISDN and leased lines. PPP and MP are enhanced by the Nautica 4000’s support of PPTP, BCP, and BACP, which extend connectivity, ensure adequate bandwidth, and provide security. A Nautica 4000 can also be configured to function as a local DHCP server for workstations directly connected to the local Ethernet segment. This allows IP addresses to be dynamically allocated without an ISDN call being placed to the central site. PPTP allows PC users to extend the PPP connection over a composite path of LAN and ISDN links. An extension of PPP, PPTP supports Virtual Private Networks (VPNs) and provides branch offices and remote/mobile users with low-cost access to corporate network resources through an Internet connection. This eliminates long distance charges as well as management issues associated with maintaining private networks. BCP allows nonrouted protocols such as AppleTalk to be bridged over a PPP link to any other router or bridge supporting the PPP/BCP standard. DHCP and BootP support provides major corporations and service providers with increased flexibility when determining and implementing their IP address allocation strategies. Dynamic IP Addressing This feature allows an ISP or corporate IP address administrator to dynamically allocate an external IP address to any Nautica series platform for the duration of its connection. This is achieved through the use of PPP and the Internet Protocol Control Protocol (PPP/IPCP), or DHCP. This automatic address allocation technique can be enhanced, where required, by using the DHCP server feature to allow the Nautica series access router to dynamically allocate local (internal) IP addresses to the hosts, without activating the ISDN link, as is required when attached to a local LAN. Frame Relay NauticaRS integrates incoming Frame Relay traffic from Frame Relay access devices such as the Nautica CLAM, with dial-in traffic to incorporate networks or the Internet over public or private Frame Relay networks. Nautica 4000 routers can support up to 64 Permanent Virtual Circuits (PVCs) over a Frame Relay network. NauticaRS supports RFC1490 encapsulation, ensuring multivendor interoperability over Frame Relay for IP/IPX routing and transparent bridging. BACP manages the bandwidth available during Multilink calls. With BACP, a platform receiving the call has the ability to negotiate bandwidth with the platform initiating the call. The negotiation can be based on available resources or through the dynamic monitoring of the actual traffic across the link. This solves the problem of insufficient bandwidth, which often occurs when ISDN links are repeatedly initialized and brought down (thrashing), by making sure that both ends have adequate bandwidth for operation. Data Compression NauticaRS software enables the Nautica 4000 to increase the amount of data that can be carried across an ISDN or leased line. Bay Networks data compression support improves performance and throughput without compromising compatibility by using standards-based techniques. Compression interoperability is available in a wide array of remote environments, from third-party routers to Microsoft Windows workstations. Dial Services NauticaRS dial-up services ensure remote office connectivity and availability with features such as Dial-onDemand, Bandwidth-on-Demand, and Dial Backup. The Nautica 4000 can accept and make calls to standalone ISDN access routers with PC-integral or standalone ISDN Terminal Adapters over PPP or V.120. When equipped with integrated modems, the Nautica 4000 can accept dial-up calls from remote users dialing in with analog modems. The Nautica 4000 will automatically route incoming analog calls to an available modem. Dial-On-Demand The Nautica 4000 routers take full advantage of the speed and bandwidth of ISDN lines while maintaining control of call costs with ISDN Dial-on-Demand. A link is automatically brought up when there is data to transfer and closes down the link once traffic has stopped for a specified amount of time. Sites with intermittent data transfers can realize maximum cost savings connections using this feature. Bandwidth-on-Demand During peak usage periods, the NauticaRS Bandwidth-on-Demand feature gives additional bandwidth. BACP is the mechanism used to add or delete links. Once line usage reaches a predefined level, the Nautica 4000 will open an additional B-channel and load balance across channels. When line usage drops below the predefined level, the Nautica 4000 closes down one B-channel and returns to the original bandwidth. Bandwidth-on-Demand can increase the synchronous port’s bandwidth by using ISDN channels during peak traffic periods. It can also add bandwidth to ISDN B-channels that are already being used. Data Sheet Nautica 4000 5 Dial Backup The Nautica 4000 can use ISDN to back up a dedicated link. In the event that the dedicated link goes down, the Nautica 4000 activates the ISDN connection. When the dedicated link is restored, the Nautica 4000 terminates the backup connection and resumes use of the dedicated link. Minimum Call Duration Timer The Minimum Call Duration Timer is particularly cost-effective when an ISDN line is activated frequently for small data transfers. This feature minimizes recurring WAN costs by applying a set minimum call charge period. The ISDN line will be kept active for the duration of the minimum call period, allowing any subsequent data transfers to take place without clearing and subsequently redialing a second ISDN call. Configuration and Management With NauticaRS software, the Nautica 4000 provides many features that simplify configuration and provide SNMP-based network management capabilities. The Nautica 4000 can be configured and managed from any local or remote ANSI-standard terminal or from a PC on the network using Telnet. SNMP-based management systems including HP OpenView,Tivoli NetView for AIX, and Sun Microsystems Solstice Domain Manager can be used to manage the Nautica 4000. BCC This terminal-based (Teletype (TTY)-compatible) tool enables platform installation and maintenance to be performed locally or from a remote location such as the central site. It can be accessed through a terminal 6 Data Sheet Nautica 4000 attached to the Nautica 4000 or a PC running terminal emulation software or a Telnet session. With support for BCC, NauticaRS provides command line syntax, which is consistent with other Bay Networks platforms that support BCC. Nautica Configuration Wizard Bay Networks Nautica Configuration Wizard is a Windows 95 Wizard application that provides an easy-to-use GUI to set up and configure the Nautica 4000. HTML This feature provides useful status information on the Nautica 4000 using HTML. Users are provided platform independent access to useful information including routing table, active ISDN calls, ISDN history, and current NAT table. This information can be accessed via standard Web browers such as Netscape or Internet Explorer. Security NauticaRS allows authorized remote users to reach all the information they need while protecting the entire network from nonsanctioned access. Supports for RADIUS, a standards-based authentication system, lets the Nautica 4000 fit easily into an organization’s existing network security design. This client/server-based security protocol makes it easy to manage large-scale remote access applications from a central site. The Nautica 4000 is supported by Bay Networks Nautica RADIUS Server for Windows 95 and Windows NT. RADIUS offers network-wide accounting, authentication, and authorization to service providers and network managers who need to maintain security when remote access is required. Several levels of comprehensive security features are provided including the CLI feature, which verifies that incoming ISDN calls are authorized to connect. For PPP connections, PAP and CHAP are supported. The Nautica 4000’s RADIUS implementation will operate with other third-party RADIUS servers. The Nautica 4000 also supports Bay Networks BaySecure™ Access Control (BSAC) RADIUS. Based on award winning technology, BSAC is an industry-standard, remote access user authentication, authorization, and accounting solution for ISPs and enterprises. BSAC is the only RADIUS server optimized for Windows NT, NetWare, and UNIX Solaris environments and the only tool integrating network operating system user directories while including embedded databases, vendor specific attributes, GUI-based user profiles, and real-time statistics for managing remote access security.
