The serial to Ethernet connections plays a crucial role in modern networks. Industrial operations like process Automation, power, and utility, security, and surveillance, transportation, etc. Lets learn about why redundancy is required in serial to ethernet connection, its working and solutions to maintain the redundancy.
2. Why Redundant Serial to Ethernet Data
Connection require?
Serial device plays a vital role in Ethernet networks. The serial to Ethernet connections made
of devices like serial to Ethernet connectors. The serial to Ethernet connections plays a
crucial role in modern networks. Industrial operations like process Automation, power, and
utility, security, and surveillance, transportation, etc. are a few industries that depends on
serial to Ethernet connections. The failure of serial to Ethernet connections results in major
losses, accidents and security issues. It is necessary to have an Ethernet network with reliable
redundancy.
Transferring transmission from serial devices to the Ethernet network helps in reaping all the
benefits of Ethernet protocol. However, since Ethernet networks consist of multiple devices,
links and loops, the chances of failure must be reduced. That is why the redundancy of such
networks is essential to be maintained.
3. Serial to Port Ethernet Connection
Serial to Ethernet technology allows connection over Transmission Control Protocol or Internet
Protocol (IP) network. Serial to Ethernet connection converters data packets into serial data signals
and vice versa. The converter receives the serial data signals and converters and forwards them to
the Ethernet-compliant devices in the form of data packets over TCP/IP. In this way, serial
communication is converted to Ethernet communication.
The main reason to adopt serial to Ethernet Data conversion is to reduce number of ports. The
serial device requires a port per transmission stream. On the other hand, Ethernet permits the
transmission of multi-stream signal over a single port by using serial to Ethernet converters.
Implementation of serial to Ethernet technology to the existing Ethernet connections is not that
complex. It benefits to enhance the performance and efficiency of the ethernet network. It helps to
transmit data globally over LAN, WLAN, and global internet-based network.
4. Serial to Ethernet Connection
Redundancy
Ethernet networks typically have multiple transmission links. From the host servers to the
Ethernet switches and further to the receiving equipment, multiple transmission links are
connected in the form of topology. When it comes to implementing serial to Ethernet
connection into the existing Ethernet network, the complexity increases with the number of
intermediate serials to Ethernet devices. The connection has to follow the standards of
topology in order to maintain redundancy. Such networks are designed and built for a
reduction in the chances of failure. Therefore, the bypass or mirrored paths of data
transmission are adopted in serial to Ethernet networks. To achieve the redundancy of a part
of serial to Ethernet networks, the bypass links are kept ideal until the functioning part of the
network fails. As the functioning links fail, the data is directed to the bypass link so that the
loss of data is prevented.
5. Solutions to Maintain Redundancy in Serial to Ethernet Connections
• Ethernet Switching Solution for LAN Bridge Mode: The LAN bridge mode features a bypass by
switching the LAN networks. The LAN bridge mode features a bypass by switching the LAN networks.
In this type of network, the serial devices are connected in a LAN network over Ethernet. This LAN is
bridged with another LAN network. In cases of data traffic, failed links, etc., the bridge is activated and
then the data can be transmitted through a second LAN.
• Ethernet Switching Solution for LAN Redundancy Mode: The Ethernet switching solution is often
configured in the serial to Ethernet converters by using networking software. It uses a backup path that
is used when data loss is noticed. The backup link often goes back to the server or looped to the series
of devices. This solution is adopted to reduce network downtime. It is compatible with ITU-G.8032 and
IEEE 802.1D/W standards. It is used in tree spanning, port mirroring features.
• Ethernet Switching Solution for LAN Dual-Subnet Mode: In this solution, the converter with dual LAN
ports are utilized. A Dual-redundancy network is built using this solution. the first redundancy path
transmits data packets between the host device and network server. Another path transmits data
between the serial devices over Ethernet. the first redundancy path transmits data packets between the
host device and network server. Another path transmits data between the serial devices over Ethernet.
