...monitor the user experience constantly and understand the impact the network is having when that experience is not good enough.
Mitigation may require upgrades to network services or equipment, but it may be sufficient in some cases simply to adjust and optimise usage of the existing network.
A port assessment by Networks First, a network management company that sponsored Quocirca's recent report, shows that in many cases network equipment is actually underutilised. With intelligent application, it should be possible to drive more performance out of existing resources.
For many it makes sense to hand the complexities of ensuring minimum network service levels to a third-party management company. The initial stage of any such assignment is discovery.
What equipment and services are in place and how do they map together to form the total network? It may seem surprising that a given organisation does not already know these facts. But most networks have been cobbled together over a number of years by a succession of network managers and contractors often dealing with tactical issues without regard for an overall long-term network strategy.
Once the network components are understood, the network's current base performance and loading can be assessed. Whether this is good or bad, it's essential for providing a benchmark for measuring how the management company is improving service levels.
The user experience needs to be measured continuously to ensure it does not regularly drop below a target baseline and that when it does, the reasons are understood and, if necessary, remedied.
The tools required for monitoring and managing network performance tend to be sophisticated and expensive. Open-source ones are available but require good technical skills to exploit. Smaller organisations may not have access to such tools and larger organisations may lack the time or wherewithal to get the most out of them.
Network management companies will have developed the expertise to use such tools and can share their cost over a number of customers, making them available to their customers, whatever their size.
Whatever steps are taken to ensure the performance, availability and security of a network, the cost of doing so must be justified by three factors.
- It must be possible to reduce running costs, or at least ensure better ongoing performance, without excessive short- to medium-term investments in new equipment and services.
- The business risks posed by the network and problems with its performance and security must be mitigated and minimum service levels guaranteed.
- A stable network that performs well and has excess capacity should be capable of being relied on to provide new business value as required.
Most businesses will not have the in-depth understanding of their networks to be sure of achieving many of these goals. Most will not even have had a recent network assessment. If they did, they may well be surprised at how poorly it is serving them and how much may be gained from addressing this issue.
A functional network is imperative for a 21st-century business. A well-managed, high-availability, high-performance and secure network can be a distinct competitive advantage. A poorly managed one can be a fundamental business risk.
