1-6 CHAPTER 1: BRIDGE/ROUTER MODULE

When no data is being passed between the workstation and server, the Bridge/Router Module closes the ISDN connection and the units at each end of the link spoof the Novell IPX protocol so that both the workstation and server believe the connection is still valid. As soon as the unit identifies that data needs to be passed to the server, the ISDN connection is re-established without the user being aware of ever being disconnected. In this way ISDN calls are kept to a minimum.

Figure 1-1 Connecting To A Remote Novell Network

In the example shown in Figure 1-1, the Main Site is connected to a Remote Site. The Main Site provides many network facilities required by remote users. The Remote Site shown has several workstations and a server but could equally consist solely of workstations or even a single workstation (such as in the case of a homeworker) but could be a similar sized site to the Main Site.

If you are connecting to the remote site over a WAN leased line link, the Bridge/Router Module has no need to spoof the IPX protocol as there is a permanent connection in place. Once the unit has determined that the server is on the Remote Site all data between the server and workstation is passed over the link.

7000 specifications

The 3Com 7000 is a robust and versatile networking solution designed to meet the demands of enterprise environments. Renowned for its reliability and scalability, the 3Com 7000 is highly suitable for organizations requiring efficient data handling and enhanced network performance. This multi-layer switching platform integrates advanced technologies, making it a preferred choice for modern businesses.

One of the standout features of the 3Com 7000 is its modular architecture. This design allows businesses to customize their network according to specific requirements by adding or replacing various modules. The modularity ensures that organizations can scale their network operations without significant downtime or the necessity of overhauling existing infrastructure. Such flexibility is vital for growing enterprises that need to adapt to variable workloads.

The 3Com 7000 also incorporates advanced Layer 3 routing capabilities. This feature enhances the efficiency of data transmission and bolsters the overall responsiveness of the network. By allowing routing functions to occur directly on the switch, it reduces latency and optimizes traffic flow, which is critical for applications requiring high availability, such as VoIP and video conferencing.

Security is another core characteristic of the 3Com 7000. It comes equipped with built-in security protocols and features such as Access Control Lists (ACLs) and VLAN support, which segregate network resources and protect sensitive data. These security measures ensure that only authorized devices can access specific segments of the network, thus fortifying the organization's information security posture.

In terms of management, the 3Com 7000 offers an intuitive interface for monitoring and controlling network operations. It supports various management protocols and software, which facilitate streamlined administration and configuration. This ease of management can significantly reduce the operational burden on IT staff, allowing them to focus on strategic initiatives.

Additionally, the 3Com 7000 is designed for high performance. It supports extensive bandwidth and low-latency communications, making it ideal for high-demand applications. The ability to handle multiple simultaneous connections without compromising speed makes it an excellent choice for enterprises that rely on real-time data processing.

In summary, the 3Com 7000 is a sophisticated networking solution characterized by its modularity, advanced routing capabilities, robust security features, user-friendly management, and high performance. These attributes make it a compelling choice for enterprises looking to enhance their networking infrastructure for a competitive edge.
