Simplifying complex networks

Operators have increasingly complex networks and are delivering increasingly complex services. They cannot deliver a consistent subscriber experience unless they know how all elements involved in a service chain are performing, in real time. This requires a correlated view that spans the complete network and the many different solutions involved in the delivery of individual services.

As everyone knows, networks are evolving at a dramatic rate. In the case of mobile, LTE has been added to existing 2 and 3G deployments, with VoLTE to follow. Fixed operators have been busy deploying IMS, while cable operators have been migrating to the latest DOCSIS standards. If we consider converged networks, that can span cable, fixed and mobile assets, the picture becomes even more complex.

At the same time, operators are striving to deliver an experience in which services can be accessed from any device and across any network. One simple example might be a voice call that is preserved as the user moves between different coverage zones – WiFi, 2G, and LTE. Or, a subscriber might wish to watch content using different devices – starting out in the morning on one device, resuming viewing on the train on another and so on. This means that an individual service must be delivered across different domains, different devices and different solutions.

While that’s a considerable challenge on its own, it also creates further problems. If a service spans multiple networks and a series of different network elements, each of which may have been delivered by different vendors, how can an operator obtain a single, consolidated view of service performance?

Operators need to obtain an end-to-end view of services and the network resources that they consume. They need to be able to consolidate information across all of the resources that are used in delivering a service. Moreover, when a service changes and requires additional resources, this must be added to the picture.

Dynamic correlation of active services is therefore essential. If operators are to successfully deliver the next generation of services, they must be able to obtain a complete, real-time picture of what actually happens when a service is activated, when it changes, so that performance levels can be maintained at all times. They need to ensure that such a view is available from a single portal, accessible by all who need it, but they also need to be sure that actions and events can trigger alarms and responses, according to the specific KPIs chosen.

NetVision delivers a complete, end-to-end view of service performance and availability, in real-time and correlated across all network elements and resources. It enables operators to simplify complex networks and to ensure they deliver the experience customers demand. Why not talk to ISPM to find out how?

ISPM creates lab to help optimise its service level management platform NetVision for hybrid network environments

As Software Defined Networks start to revolutionise the way operators deploy and manage a new generation of networks and services, ISPM has created a lab to simulate hybrid networks and to help optimise its network management platform NetVision.

Software Defined Networks (SDN) will revolutionise the way operators deploy networks and the services they provide. As well as eliminating the need for further network infrastructure investment, they will allow operators to better manage network traffic and performance, and create a new generation of virtualised services.

However legacy network infrastructures must still coexist with these new virtualised network environments, as it will be necessary to collect information from both types of networks through management protocols, the integration of plugins and APIs developed for these new network environments. This provides a challenge for operators.

So there is a growing need for operators and service providers to be able to manage hybrid network environments, and manage not only legacy network infrastructure, but also new virtualised networks based on SDN.

"The SDN will revolutionise the way you think, design and implement network infrastructures, in addition to expanding the horizons in virtualised environments in the data centre, especially for telecom and cloud service providers to service providers," Walmir Costas, systems engineer for ISPM, explained in a recent interview with BIT Magazine.

To meet this demand from operators to manage hybrid environments, ISPM has expanded the capabilities of its existing NetVision service level management platform to include integrated fault management, performance, service desk and SLA to provide a single tool that supports the complete management requirements of SDN networks in a hybrid environment.

ISPM has created a lab that simulates SDN networks and analyses how they integrate with legacy data networks. The goal was to improve the NetVision platform with a focus on managing hybrid networks with an 'over the top' view.

The result is a modular network management solution for hybrid networks that can eliminate faults in the network management process arising from the implementation of new technologies and services.

"We have invested to provide to the market a solution that can help the network operators. The NetVision platform provides better operating results and transmits these benefits to their end users," concluded Costa.

Why the service desk is the heart of your assurance framework

Faced with more demanding customers, increasing competitive pressures and a richer service portfolio, operators need more than ever to proactively manage and assure services and network infrastructure.

Proactively monitoring and preventing potential network performance and IT infrastructure problems, can help operators to reduce costs, avoid penalties associated with breaking SLA terms. Furthermore, the confidence gained from more effective network operations – through the intelligent use and presentation of critical network data optimised to the needs of any service and infrastructure – can ultimately drive your business forward by helping to attract and retain customers.

A vast array of information flows through the network, and is captured by aggregators, which can be correlated to produce an end-to-end view of network performance. Automated alarms, triggered by events that feed into other systems to generate actionable responses, are an essential component of the assurance framework.

An optimised service assurance framework ensures that operators can obtain and make sense of network performance information, statistics and reports from multiple sources – as well as plan effectively for the future.

However, it is the service desk that sits right at the heart of your OSS infrastructure and assurance framework. The service desk provides visibility and control of operational data for different users within the organisation.

It allows businesses to organise workflows to manage customer care more efficiently, track issues, enhance workflow, meet SLAs, and ultimately grow their business with individual customers. Customer care is an essential part of this and demands particular attention. Put simply, the faster issues are resolved, the greater the cost savings.

NetVision Service Desk is a complete service problem management solution that sits at the heart of all customer service activity. It ensures that requests and customer service activities are converted to measurable and actionable items.

NetVision Service Desk is a critical element for the conversion of input into operational intelligence, as well as the co-ordination of communications and management of work flows. It can help operators to concentrate and consolidate management information for technical support, help IT to investigate issues and diagnose for service improvement, gracefully manage and schedule changes and requests, help to meet SLAs, ensure compliance with international standards and best practice, among multiple further benefits.
