Drawing an Internetwork Map

Drawing an Internetwork Map

This section deals with the internetwork as a whole. The internetwork worksheets consist of an internetwork map, which shows an overview of your internetwork, and an internetwork table. You will take the following steps when filling out the internetwork worksheets:

•Draw sketches of each network in the internetwork.

•Write network names, IP network addresses, and network types.

•Draw gateway nodes.

•Indicate network boundaries.

An internetwork map provides information about the whole internetwork. Figure 3-1is an example of an internetwork map. This sample internetwork will be used throughout the instructions in this chapter to help explain the other drawings and tables that make up the configuration worksheets.

Before you can draw your internetwork map, you must know how many networks your internetwork will contain, and you must know each network type (ThinLAN, Token Ring, FDDI, 100VG-AnyLAN, 100Base-T, NS Point-to-Point, or X.25). The internetwork in the example (Figure 3-1)contains six networks. NET1 and NET5 are LANs, NET1 is 100Base-T LAN and NET5 is a ThinLAN, NET2 is a Point-to-Point network, NET3 is an X.25 network, NET4 is a Token Ring network, and NET6 is an FDDI network.

If you have an X.25 network, you should indicate the presence of each Datacomm and Terminal Controller (DTC) in your internetwork map, as shown in this example (Figure 3-1). Both the NS 3000/iX node and the DTC must be specially configured for X.25 links.

E3000 MPE/IX, E3000/IX specifications

The HP E3000 series, particularly the E3000/IX and E3000 MPE/IX, represents a significant milestone in the evolution of business computing, developed by Hewlett-Packard (HP) during the late 1970s and early 1980s. These systems were designed to provide robust, reliable, and efficient operation for mid-sized businesses, leveraging the power of the MPE (Multi-Programming Executive) operating system.

One of the main features of the HP E3000 series is its multitasking capability. MPE/IX allows for multiple applications to run concurrently, maximizing the utilization of system resources. This is particularly beneficial for organizations that require simultaneous access to various business applications, ensuring enhanced productivity and efficiency.

The HP E3000/IX architecture is built on a powerful 16-bit or 32-bit microprocessor, enabling it to handle substantial workloads. The system architecture is known for its modular design, which allows for easy upgrades and customization. This flexibility is essential for businesses that need to adapt to changing demands without overhauling their entire computing infrastructure.

Another notable technology incorporated into the HP E3000 series is its support for a range of storage solutions. The E3000 systems were compatible with various disk drives, providing organizations with options for data storage that matched their performance and capacity requirements. Additionally, they featured advanced data management capabilities, such as built-in backup and recovery systems, ensuring that critical business information remained secure and accessible.

Beyond hardware capabilities, HP E3000/IX and MPE/IX systems provide extensive programming support. They included tools for developing custom applications, with support for languages such as COBOL, BASIC, and FORTRAN. This versatility made it easier for businesses to tailor their software solutions to their specific needs, enhancing operational effectiveness.

Networking capabilities were also a significant innovation of the E3000 series. The systems offered robust support for various networking protocols, allowing for seamless integration with other computing environments. This facilitated communication and collaboration within an organization, as well as with external partners and clients.

In summary, the HP E3000/IX and E3000 MPE/IX systems were pivotal in delivering reliable computing power to mid-sized enterprises. With their multitasking operating system, modular architecture, advanced data management, and programming support, these systems provided an adaptable and comprehensive solution for evolving business needs. The legacy of the E3000 series is evident in how it paved the way for modern enterprise computing, focusing on flexibility, scalability, and efficiency.
