Managing Your Satellite Networks
Senior Consultant, Parallel
When the African Banking Corporation (ABC) decided to add new banking applications to its network, IT performance suffered to the point where workers could not communicate effectively - even email was down at one point. This presented a major problem for an organisation that employs over 550 people in offices located across seven countries.
So why does this kind of nightmare situation occur? Very often it is due to the fact that networks are not properly managed. Too many businesses are losing precious time and resources due to problems such as slow response times and downtime. A badly functioning network can result in a loss of reputation, productivity and revenue.
Many businesses using traditional, terrestrial networks already embrace the need for network management. But many countries, particularly those in the third world, do not have the terrestrial communications infrastructure that the developed world enjoys. Therefore an alternative, and in many cases more suitable, method is rapidly gaining in popularity - the satellite.
Satellite networks use VSAT (Very Small Aperture Terminal) technology to relay information between sites without the need for a terrestrial communications infrastructure.
However, many users of this technology are making a crucial mistake by not recognising that the management of satellite networks carries additional complications. Different issues must be tackled if these networks are to function efficiently. This is a challenge that Parallel has confronted.
'Out-of-the-box' Network Management Systems (NMSs) are designed to work for terrestrial systems - not satellites. It is crucial this is understood. Several factors render the traditional off-the-shelf NMS ineffective for satellite networks:
|Characteristic||Terrestrial Networks||Satellite Networks|
|Latency (Response Time)||Low||High|
|Failures||Sites up or down||Can be partial|
|Weather||-||Can cause degradation or loss of signal|
|Sun Alignment||-||Can cause outages|
|Equipment Alignment||-||Misalignment can sap signal strength|
|Equipment Access||Usually easy||Sites can be remote|
|Band Management||In or out of band||In band only|
Satellite technology allows much more flexibility than terrestrial systems and increases what is possible for multi-national organisations. But in order to take full advantage of the technology, we must get the management right. The differences are clear - yet what can be done?
Parallel believes in a structured, planned approach. In a recent white paper the company made many recommendations including:
- Find a reputable VSAT service provider and properly plan site equipment.
- Consider outsourcing if specialist staff are not available.
- A good development cycle of an NMS is vital, from evaluation, to design, to implementation, to a second evaluation.
Efficient NMS systems, such as those created and employed by Parallel, will save money by predicting outages and proactively dealing with them in a cost-effective manner. To achieve maximum efficiency a management solution must achieve a high level of automation. Parallel has developed a system where tickets are automatically closed for routine faults, meaning fewer operators are needed to monitor incidents and those that are employed are used productively to investigate more serious failures. Costly engineer site visits are also reduced.
So if you are an organisation setting up a VSAT network, what factors must be considered when choosing a VSAT Network Management partner?
- Avoid companies focused on selling an 'out-of-the-box' product. They WILL NOT WORK.
- Look for a company with proven experience of VSAT technology.
- If you have previously invested in network management products, find a company that will integrate new solutions into your existing infrastructure.
The African Banking Corporation (ABC) is now benefiting from Parallel's expertise and there will be no return to the nightmare scenario they faced before. But success stories such as ABC's are not a result of good fortune, they are down to an awareness of how to manage satellite networks. Out-of-the-box products are not enough.
So, if you are setting up a VSAT network, do not rely on the traditional NMS and/or the vendor's hardware management solution - there's so much more to consider!
