Networks for Mission Critical Applications and their Challenges
Your check-list for planning network infrastructures of mission critical applications like IP video surveillance and security
If the infrastructure of mission critical application goes down, this can result in serious issues, damages or life-threatening situations. As a result, requirements for the network of such applications are significantly higher.
The following key issues have to be considered when planning a robust and secure IT infrastructure for security applications in mission critical environments.
- Network for mission critical applications need to be designed from the very start to maximised operating time in harsh environments - this means taking a different approach to everything from hardware to functionality.
- Network availability needs to be as high as possible, which requires ample transmission and power redundancy.
- Security must be enhanced to prevent unauthorized access and occasional events.
- As such networks can be located on large remote areas, easy maintenance from the central office is extremely important. Another vital topic is interoperability – it starts from the need to work with many different types of equipment and lands with interaction with SCADA systems.
- Development of Ethernet technology stimulated the migration of various security devices to IP network, so a higher number of PoE+ ports becoming more important.
- Although some devices are still ‘non-IP’ and need to be connected to the network and managed at the lowest cost, preferably with switches’ I/O modules.
