Shiva announces major software upgrade for family of remote access servers; ShivOS release 4.0 improves performance, enhances ease-of-use, controls WAN costs and simplifies deployment of ISDN technology.BEDFORD, Mass.--(BUSINESS WIRE)--March 11, 1996--Shiva Corporation today announced release 4.0 of the Shiva Shiva or Siva (shē`və), one of the greatest gods of Hinduism, also called Mahadeva. The "horned god" and phallic worship of the Indus valley civilization may have been a prototype of Shiva worship or Shaivism. operating system operating system (OS) Software that controls the operation of a computer, directs the input and output of data, keeps track of files, and controls the processing of computer programs. (ShivOS ) software for its family of remote access servers, including the LanRover, LanRover/PLUS, WebRover, and NetModem/E product lines. ShivOS 4.0 substantially enhances ease-of-use, improves performance, controls wide area network (WAN) costs and simplifies ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. installation. ShivOS 4.0 is a component of Shiva's Enterprise ISDN strategy to provide high-speed, cost-effective and transparent access to information with support for industry standards and ease-of-deployment features. ShivOS 4.0 adds integrated ISDN to the Shiva remote access solution allowing network managers to manage analog and ISDN multiprotocol access to private LANs, intranets, and Internets within one integrated platform. Shiva also announced today the availability of integrated ISDN Basic Rate Interface (BRI See ISDN. BRI - Basic Rate Interface ) hardware modules for its LanRover/PLUS remote access server. (See today's related LanRover/PLUS BRI release for more details.) "As remote access becomes increasingly critical to key business processes, customers want more than connectivity solutions," said Woody Benson, senior vice president of worldwide sales and marketing, Shiva Corporation. "Unlike competitive personal routers that are designed for TCP/IP-only environments and function best only with server equipment from the same vendor, ShivOS 4.0 enables full multiprotocol LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. access with an open choice of multiple client-side ISDN cards." Optimized Performance/Multilink PPP (Point-to-Point Protocol) The most popular method for transporting IP packets over a serial link between the user and the ISP. Developed in 1994 by the IETF and superseding the SLIP protocol, PPP establishes the session between the user's computer and the ISP using Shiva's ShivOS 4.0 software is an end-to-end solution (jargon) end-to-end solution - (E2ES) A term that suggests that the supplier of an application program or system will provide all the hardware and/or software components and resouces to meet the customer's requirement and no other supplier need be involved. Compare: turn-key solution. designed to support bursty Refers to data that is transferred or transmitted in short, uneven spurts. LAN traffic is typically bursty. Contrast with streaming data. , irregular, multiprotocol traffic characteristic of dial-in communications. It features Multilink PPP See PPP. channel aggregation, which increases performance significantly. With Shiva's modular LanRover/PLUS server with integrated BRI modules, users can obtain speeds significantly faster than the best 28.8 modem connection. Using LanRover/PLUS in a client-to-LAN environment, dial-in users can aggregate two 64-Kbps B channels for full 128-Kbps throughput. In a LAN-to-LAN environment, LanRover/PLUS 4.0 users can aggregate eight analog and/or digital channels for 512-Kbps data transfer speeds. Additionally, 4.0 implements STAC 1. (language) STAC - Storage Allocation and Coding Program. 2. (company) STAC - The company responsible for Stacker and stac compression. http://stac.com/. data compression data compression Process of reducing the amount of data needed for storage or transmission of a given piece of information (text, graphics, video, sound, etc.), typically by use of encoding techniques. at both ends of the connection for optimum performance. Continued Focus on Client Ease-of-Use With ShivOS 4.0, Shiva has provided a ShivaRemote client installation scripting utility that facilitates enterprise-wide client deployment. It includes an intelligent connection "wizard" that guides users through ShivaRemote client connection file setup. Additionally, users can save ShivaRemote client connection events, such as PPP negotiation details or compression statistics, to a file or display them on the screen to help them resolve potential connection issues. ShivOS 4.0 also has a "power switching" feature that allows users to switch quickly between two or more communications adapters. This is ideal for remote users who use one type of communication adapter at home, such as ISDN, and another type of adapter when traveling, such as a V.34 modem. "ShivOs 4.0 removes the complexity of implementing ISDN and makes overall installation simple," said George Staton, assistant vice president of LAN support services support services Psychology Non-health care-related ancillary services–eg, transportation, financial aid, support groups, homemaker services, respite services, and other services for Commerce Bank. "With virtual connections, the dial-in access is seamless and instantaneous; it's the next best thing to being on the LAN." Tariff Management for Controlling Connect Time Costs With ShivOS 4.0, Shiva extends its Tariff Management technology to include the concept of "virtual connections" for client-to-LAN environments. This means that dial-in users can now take advantage of ISDN's fast call set-up times In telecommunication, the term call set-up time has the following meanings: 1. The overall length of time required to establish a circuit-switched call between users. 2. and high performance while minimizing WAN connect-time costs by only keeping dial-in links active when actual data is being sent. Until now, this feature has only been available in LAN-to-LAN environments (including personal ISDN routers A device that enables several users on a network to access the Internet via ISDN. Also known as an ISDN LAN modem, it contains a BRI ISDN port and an Ethernet port. It may also provide several Ethernet ports, which lets it serve as a central Ethernet hub for a small workgroup. ). In addition to lower telephone bills, virtual connections provide superior ease-of-use by making set-up and tear-down of calls transparent to the user. Additional Tariff Management features of ShivOS 4.0 include enhanced data compression, flexible routing table A database in a router that contains the current network topology. See routing protocol. updates, Multilink PPP channel aggregation and spoofing (1) Faking the sending address of a transmission in order to gain illegal entry into a secure system. See e-mail spoofing. (2) Creating fake responses or signals in order to keep a session active and prevent timeouts. . Spoofing technology emulates an active connection on both sides of a LAN-to-LAN or client-to-LAN connection while the connection is in a suspended or disconnected state. "ShivOS 4.0's Tariff Management technologies answer the urgent need to manage ISDN connect time charges, which can represent up to 85 percent of the total cost of ISDN remote access solutions," said industry analyst Michael Howard
IP Dial-out/Windows 32-bit Virtual Device Drivers See VxD. (operating system) Virtual Device Driver - (VxD) A device driver under Windows 3.x/Windows 95 running as part of the kernel and thus having access to the memory of the kernel and all running processes as well as raw access to the hardware. ShivOS 4.0 provides IP dial-out. This enables Internet users Internet user n → internauta m/f Internet user Internet n → internaute m/f in TCP/IP TCP/IP in full Transmission Control Protocol/Internet Protocol Standard Internet communications protocols that allow digital computers to communicate over long distances. only environments to take advantage of Shiva's dial-out software which allows for seamless redirection Diverting data from their normal destination to another; for example, to a disk file instead of the printer, or to a server's disk instead of the local disk. See virtual directory, symbolic link, shortcut, redirector and DOS redirection. 1. of PC communication ports to LanRover attached modems. For Windows 3.1 and 3.11 users, the ShivaRemote dial-in client has been improved to run as a Virtual Device Driver (VxD) occupying a mere 2K of conventional DOS memory. This saves 32K of memory and allows users to execute more simultaneous applications. Open Client Platform for ISDN interoperability The capability of two or more hardware devices or two or more software routines to work harmoniously together. For example, in an Ethernet network, display adapters, hubs, switches and routers from different vendors must conform to the Ethernet standard and interoperate with each other. ShivOS 4.0 ensures interoperability by conforming to the Multilink PPP industry standard. It offers a high performance port driver that provides support for internal client ISDN terminal
Freedom Series ISDN access cards, and Synaptel's Syncard. ShivOS 4.0
also includes an application programming interface for client ISDN
adapters which will enable vendors to write drivers for their
specific hardware. This port driver API will facilitate the
interoperability of high performance client ISDN communications
adapters enabling more choices, flexibility and interoperability for
ShivOS 4.0 users in the future.
In addition, Shiva is committed to supporting Bandwidth
Allocation Control Protocol (BACP) for the dynamic allocation of
bandwidth. BACP is an extension to the MLP protocol enabling ISDN
channels to be added or reduced as needed. BACP has been submitted
to the Internet Engineering Task Force as an RFC by Shiva and several
other networking industry leaders (See announcement, January 4,
1996).
New Management and Security Features
ShivOS 4.0 adds many new features for network managers enabling
them to completely manage Shiva remote access servers from either IP,
IPX, AppleTalk or command shell environments. Protocols and features
can be managed by Windows, Windows 95 or Macintosh versions of Shiva
NetManager software. In addition, ShivOS 4.0 extends the SNMP
management capabilities of the device by providing Management
Information Bases (MIBs) for HP OpenView, Sun NetManager, and other
SNMP-based management tools.
Security features have been added or augmented to allow for more
security options and better integration with various third-party
devices. ShivOS 4.0 provides support for TACACS, TACACS+, and
RADIUS. It also supports Security Dynamics ACE Server and Digital
Pathways Defender Server software.
