At one time in the not-too-distant past, a service call or truck provided the only workable solution for dealing with unresponsive routers or switches that had crashed and disrupted network communication. Although this approach (eventually) took care of the problem, it also resulted in excessive expenses, hassles and network downtime while you waited for your service team to arrive on-site. Fortunately, thanks to devices such as GigE Serial Console Servers, there are now other, more effective ways to deal with network outages.

Large enterprise networks, like those found in public utilities applications, present many unique challenges when implementing an out-of-band management solution. Due to the sheer size and complexity of most public utilities networks, an effective out-of-band management solution must provide sufficient scalability to meet the needs of both large equipment sites such as data centers and also small equipment sites such as pipeline monitoring stations.
When a critical network element located at a remote branch office malfunctions and disrupts network communication, an out-of-band management solution allows tech support personnel to address the problem immediately, without the hassles, expenses or delays associated with a physical truck roll or service call. When an effective out-of-band management solution is deployed at a remote branch office, personnel at the NOC can promptly access console port command functions on the remote device or execute a reboot without the need to actually travel to the site in person, minimizing downtime and ensuring that vital network based services are available when needed.
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.
An effective out-of-band management solution for large enterprise network applications must be able to serve the needs of a wide variety of different types of remote network equipment sites. In order to minimize downtime and ensure access to vital services, an out-of-band management solution in a large enterprise network must be able to provide remote power reboot control and console access for critical network elements located at remote data centers, microwave antenna sites, branch offices and many other diverse types of remote installations.
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.
The task of managing devices in mobile media applications presents a unique set of challenges for technical support personnel. For one thing, the mobile and often remote nature of this type of application means that traditional service calls or on-site tech personnel are often impractical, for another, when a vital device in an outside broadcast van or in-flight entertainment system crashes, customers start to complain immediately. In order to effectively resolve problems in mobile media applications, tech support personnel need a solution that provides remote access to power control, reboot and console port command functions on critical system elements.
