Is Your Network Infrastructure Ready for the IIoT?


The Industrial Internet of Things (IIoT) trend aims to improve efficiency and productivity by connecting different devices together as well as collecting and analyzing large volumes of data to offer accurate information. However, before reaping the benefits of the IIoT, users need to ensure that the correct infrastructure is in place. To make sure your network is ready for the IIoT, check out five of the most frequently mentioned questions........more



White Paper

Ensure Nonstop IP Surveillance with an Optimized Industrial Ethernet Network


If your CCTV system uses multicast transmission over a redundant ring, then even if your ring redundancy protocol is able to activate backup paths in a fraction of a second when a disconnection occurs, it could still take more than 2 minutes for your multicast video streams to recover. This is because a number of different protocols—including IGMP (Internet Group Management Protocol) and PIM-DM (Protocol Independent Multicast - Dense Mode)—are implemented to transmit your video packets around the network, and these standard protocols are not designed for mission-critical applications. In this white paper, we show how implementing an appropriate non-standard proprietary protocol can optimize your network for video stream transmission, and in this way overcome IGMP’s sluggishness.........more
