HIRSCHMANN Switches (Germany)

Brand Introduction:

Hirschmann Electronics, located in Neckartenzlingen, Germany, offers a range of products including mobile transmission and reception systems using analog and digital broadcast television transmission technologies, enterprise and industrial network solutions, and fieldbus systems. Founded in 1924 by Richard Hirschmann, the father of the "banana plug," the company has grown from a one-man operation into a modern enterprise in the field of modern communications over 81 years.

Hirschmann Company History:

Since January 1, 1997, Hirschmann has been part of the Rheinmetall Group's electronics division as a member of Aditron AG, developing and manufacturing automotive electronics, multimedia communication systems, and automated network systems. On March 24, 2004, Hirschmann joined the HgCapital Group, a financial investment company.

Hirschmann's technological strengths are primarily reflected in automotive communication systems, multimedia electronics, automated network solutions, and electronic control systems. To clarify the company structure, a multimedia division, Hirschmann Multimedia Electronics, was established in early January 2003. Hirschmann has since acquired its former sister company, PAT, located in Ettlingen, whose electronic control systems division is now part of the Hirschmann Group.

In computer network systems, the concept of switching represents an improvement over shared operating modes. A hub is a type of shared device. The hub itself cannot identify the destination address. When host A transmits data to host B within the same local area network, the data packet is broadcast on a network based on a hub architecture. Each terminal determines whether to receive the packet by verifying the address information in the packet header. In this mode, only one set of data frames can be transmitted on the network at a time; if a collision occurs, a retry is required. This method is called shared network bandwidth.

Main Features:

Key functions include physical addressing, network topology, error checking, frame sequencing, and flow control. Currently, switches also possess some new features, such as support for VLANs (Virtual Local Area Networks), link aggregation, and some even have firewall functionality.

Learning: Ethernet switches know the MAC address of each device connected to their port and store the mapping between the address and the corresponding port in a MAC address table cached by the switch.

Forwarding/Filtering: When a data frame's destination address is mapped in the MAC address table, it is forwarded to the port connecting to the destination node instead of all ports (if the data frame is a broadcast/multicast frame, it is forwarded to all ports).

Loop Elimination: When a switch includes a redundant loop, the Ethernet switch avoids loop generation through the Spanning Tree Protocol (STP) while allowing for backup paths.

In addition to connecting networks of the same type, switches can also interconnect different types of networks (such as Ethernet and Fast Ethernet). Many switches today offer high-speed connection ports supporting Fast Ethernet or FDDI, used to connect other switches in the network or provide additional bandwidth for bandwidth-intensive critical servers.

Generally, each port on a switch is used to connect an independent network segment, but sometimes, to provide faster access speeds, we can directly connect important network computers to the switch's ports. In this way, critical network servers and important users can enjoy faster access speeds and support larger data volumes.
