Public utilities networks are generally both large and complex. With that in mind, it also follows that an effective out-of-band management solution for a public utilities network application must as well be relatively large and complex in order to solve the many challenges of managing a large number of devices spread across a complex network infrastructure, featuring a variety of different sizes and types of remote equipment sites. An efficient out-of-band management solution must be able to deal with problems at data centers, microwave antenna sites and also small monitoring stations.

How to Avoid Potential Pitfalls when Implementing an Out-of-Band Management Solution in a Large Enterprise NetworkMonday, August 3rd, 2015
The task of designing an out-of-band management solution for a large enterprise network presents a number of different challenges that are not commonly encountered in smaller scale out-of-band management solutions. In addition to the sheer size and scope involved in large enterprise networks, an effective out-of-band solution must also be able to address many other issues and must include the need to adapt to a variety of different sized remote equipment sites with varying power needs and communication capabilities.
Out-of-Band Management provides tech support personnel with a secondary, alternative avenue for communication with remote network elements during network outages. If a vital network element at a distant facility crashes and takes down network communication with it, an out-of-band management solution provides the most efficient means to contact unresponsive devices and restore network communication in a timely fashion. In a typical network application, the presence of both a primary and secondary avenue for communication with remote network elements is usually enough to get the job done. But in mission critical network applications, such as managing remote network elements in gas pipeline support roles often more than two avenues for communications are needed and a redundant out-of-band management strategy is required.
In most network applications, an out-of-band management solution equips support personnel with an alternative means to access console port command functions and reboot capabilities at remote sites when the primary avenue for communication is unavailable. When a critical device at a remote site crashes and takes down network communication, an out-of-band management solution ensures that NOC personnel can still communicate with the remote site via a secondary out-of-band channel. Although the presence of two separate avenues of communication provides an acceptable level of reliability for most everyday network applications, mission critical network applications in oil refineries often require a redundant out-of-band management solution that provides at least three avenues for communication with remote devices.
An effective out-of-band management solution provides support personnel with a secondary avenue for communicating with vital network elements at remote sites in the event that the primary avenue for communication is temporarily out of service. This means that even when the network is down, technicians can still communicate with remote devices via a secondary, out-of-band channel such as dial-up in order to restore network. Although this strategy serves well in most situations, there are also cases such as oil and gas industry network applications where the critical nature of the process demands a third avenue for communication. In these cases, a redundant out-of-band management solution can provide support personnel with an extra channel for communication with remote network equipment.
Unresponsive network elements on oil tankers can present a bit of a challenge to both on-board and shore based tech support personnel … especially if that oil tanker is currently at sea. When a router or firewall crashes and takes down important navigation, helideck monitoring or communication systems with it, network administrators need to be able to act fast to restore normal operation before safety issues ensue. There’s often no time to fly in a tech support team or take off on a trek to the other end of the ship to investigate problems in a remote equipment enclosure; NOC personnel need an out-of-band management solution that can deal with the problem at once.
When a crucial network device located at a distant pipeline monitoring station crashes and takes down the station’s monitoring or communication capabilities, the race is on to remedy the problem before the outage forces a temporary shutdown of the pipeline’s delivery functions. In cases like this, there isn’t time to wait for a service team to travel to the remote site and restore communication and monitoring functions. Network support personnel need an out-of-band management solution that allows them to deal with the problem at the pipeline monitoring station immediately.
Drill rigs and production platforms present a difficult challenge for network support personnel. When a router or firewall located on a distant petroleum production facility becomes unresponsive, NOC personnel need to fix the problem immediately in order to avoid downtime, but the remote location of the site often makes a quick response somewhat problematic. Fortunately, WTI’s RSM-8R8 Remote Site Managers can drastically simplify the task of dealing with network problems on remote drill rigs, production platforms and support vessels.
The task of managing network equipment in oil and gas industry applications often involves dealing with problems at facilities and equipment enclosures that are miles and miles away from the central office. When a crucial network element located at a distant oil rig, pipeline monitoring station or oil tanker refuses to respond to commands, NOC personnel in the petroleum industry need a means to deal with the problem immediately, without the delays associated with a physical service call.
One of worlds’ largest oil companies has the mission-critical task of monitoring sensors across large scale oil field deployments. The company’s oil field monitoring equipment and servers must be up 24/7, so redundant power circuits are used whenever possible. The oil company has many single-power-supply network devices that must always be running. Because they are single power supply, if the UPS is taken down, they will also lose power to critical network elements.
The company was looking for a way to provide dual power to network elements and monitoring devices in case of UPS issues. Also, the NOC of the facility wanted the ability to reboot these critical devices and sensors remotely at all times.
