Rural Access Networks – Network Management challenges

Rural Access Networks – Network Management challenges

Universal Service concerns the availability of high-speed telecommunication services to anyone within a nation’s territory, inclusive of rural and insular areas.

Broadband can promote society’s advancement through various applications, which include webbanking, e-commerce, Infotainment, Social Networking and e-Government.

The management of rural networks encounters multiple challenges:

  • Convergence of mobile broadband and fixed broadband networks.
  • Support of a large number of subscribers who are geographically dispersed while having multi-service
    requirements.
  • End-to-end service provisioning and QoS assurance over a variety of network topologies and technologies.

 

What to Expect from a Rural Network NMS system

Faster service activation and configuration across multiple technologies can be achieved only via automation. Human errors must be avoided, especially when the work to be done is complex and technically challenging. The capability to select only the end points of a service and then having an NMS system configuring automatically all the other points and technologies is really important.
Environmentally-aware monitoring can greatly reduce fault troubleshooting & rectification. Rural networks depend on UPSs, batteries and some times green enrgy sources to increase their availability and their installation may be done using outdoor cabinets that use fans and air-conditioning for cooling and to avoid over-heating. All these devices must be monitored to quickly identify failures.
Management of access and transport network segments from a single application is cost-effective. Fewer management systems at the NOC will reduce operational expenses (OpEx), including training, installation, support and maintenance costs.
Complex rural networks may require multiple staff with different skill sets to operate, support and maintain. Designing access security is very important, in order to be able to audit and troubleshoot failures and mis-configurations. Using access domains, local maintenance personnel will be able to proactively monitor their assigned equipment.
Fast bulk deployment of services can be achieved with wizards. Why should you have to repeat the configuration and provisioning of services that are identical? Wizards can provision multiple services via templates that can be even prepared and tested off-line.
Designing and implementing a unified management system that manages multiple technologies from multiple vendors can simplify service assurance that increases service availability. Correlation rules can be applied that correlate alarms from different technologies and sources, grealty reducing the number of notifications a user must handle.

Architecture of Rural Networks and respective NMS

Rural Network and how to manage it

Rural Networks require a centralized unified NMS solution

NMS must provision services at any location, over any access technology i.e. WiMAX Mobile, ADSL, POTS, backhauled via any transmission technology i.e. PtP, PtMP. E-band, managing any device, i.e. cabinets, CPEs, UPS etc.

Do you agree? What are the major challenges of rural networks management not included here?
