FDDI Applications

Configuring FDDI Frame Translation Settings

The HSIM-F6 interface must be conÞgured to translate packets from an FDDI frame format to an Ethernet frame format (and vice versa) when bridging packets between FDDI and Ethernet networks. The Frame Translation window lets you set the parameters for frame translation.

To access the FDDI Translation window (Figure 6-8):

1.In the Chassis View window, click on FDDI to display the FDDI menu.

2.Click on Frame Translation.

Information about Ethernet and FDDI Frame Types

There are four frame types which can be transmitted on an IEEE 802.3/Ethernet network Ð Ethernet II, Ethernet 802.2, Ethernet 802.3 (or Raw Ethernet), and Ethernet SNAP; there two frame types which can be transmitted on an FDDI network: FDDI 802.2 and FDDI SNAP. Each of these frame types is described in more detail in the sections that follow. Bridges connecting IEEE 802.3/Ethernet LANs to an FDDI ring have to provide frame translation, as there are addressing and frame format differences between the two network topology types.

For an Ethernet frame format to be forwarded onto an FDDI network, the Length (IEEE 802/SNAP) or Type (Ethernet II) Þeld must be removed (along with any frame padding), an FDDI Frame Control Þeld must be added, the bit-order of the address Þelds must be reversed, and the frameÕs CRC Þeld must be recomputed.

2000 specifications

Cabletron Systems was a prominent company in the networking and communications industry during the late 20th century, and by the year 2000, it had established itself as a leader in providing high-performance networking solutions. The company was known for its innovative approach to network architecture and its commitment to delivering reliable products that enabled seamless connectivity in various environments.

One of the primary features of Cabletron Systems in 2000 was its advanced networking technologies, including Local Area Network (LAN) and Wide Area Network (WAN) solutions. The company specialized in developing multi-layer switches that could efficiently manage traffic and deliver high-speed data transfer. Their products were particularly popular in enterprise settings, where network performance and reliability were paramount.

Cabletron's solutions included a range of products, from Ethernet switches to routers, which were designed with scalability and flexibility in mind. This allowed businesses to adapt their networks to accommodate growth, without the need for a complete overhaul of their infrastructure. The company’s Integrated Networking Architecture (INA) was a significant innovation during this period, enabling efficient communication and management of diverse network resources.

Another major characteristic of Cabletron Systems was its commitment to interoperability. The company’s products were designed to be compatible with several industry standards, ensuring that organizations could easily integrate Cabletron solutions into their existing networks. This focus on compatibility helped to foster collaboration among different devices and systems, further enhancing network efficiency.

Security was also a key feature of Cabletron’s offerings in 2000. With growing concerns about data breaches and unauthorized access, the company incorporated advanced security measures into its products. These features included robust authentication protocols, encryption options, and secure management interfaces, which helped safeguard sensitive data during transmission.

Customer support and service were paramount to Cabletron Systems' business model. The company provided extensive resources, including training and technical support, to ensure that customers could maximize the potential of their networking solutions. This dedication to customer satisfaction contributed significantly to Cabletron’s reputation in the marketplace.

In summary, Cabletron Systems in 2000 emerged as a frontrunner in the networking industry, characterized by its innovative technologies, commitment to interoperability, emphasis on security, and strong customer support. Their products and solutions were designed to empower businesses, helping them achieve greater efficiency, scalability, and reliability in their network operations.
