Next-generation (NGN) networks can help service providers meet customer requirements. Today, multi-protocol label switching (MPLS) technology has been seen as a service integration standard, allowing service providers to avoid the need to use many different small networks and still provide many type of service.
The emergence of "global networks" that deal with different signals such as voice, data transmission or communication signals has had a profound impact on both service providers and large customers. .
It's easy to see that adding more services will increase profitability, but implementation of complex structured networks allows users to use many different systems (such as pure IP networks to Providing basic IP services such as IP VPNs, firewalls to prevent external sabotage, and ATM networks to provide class 2 services such as voice and data transmission, etc.) was a post expensive in the past.
What factors will create success for a service provider in a world where there is no boundary between telecommunications, computers and communications?
A service provider must not only deploy a service infrastructure based on a common network but also build and consolidate the network to create new services. These services must be novel, unique, affordable, and meet customer requirements at a high level. In an environment where fast provision of a new service is a competitive one, the network also needs to be optimized to be able to offer a variety of services that generate a lot of profit.
For service providers, the key is to intelligently integrate the infrastructure of the new network with the existing network and ensure that it is easy to exploit. The integration of old equipment systems with new is never easy and it will be a big hindrance for service delivery.
The network must meet the requirements of the quality of service different to the customer, must meet the individual requirements and requirements as committed to each customer. At the same time, services need to be large enough to accommodate an increasing number of customers and also be small enough to meet the needs of smaller customers, which vendors previously did. Service levels are usually not interested. The provision of management services will be considered as the focus for meeting these requirements.
Providing IPvPN network services is an example, with varying levels of service agreements and the management of client-premises equipment, along with the provision of network services that will require service providers. must manage a large number of different network elements. First, they need to ensure the quality of service as agreed with each customer; Secondly, traffic can flow outside the pure IP network to the voice layer; And third, they need to meet different bandwidth needs for different types of customers as well as quality of service to the customer at the same time. And above all, service providers are eager to offer various features of the system such as security, speed, connectivity options, flexible pricing plans, service delivery, management devices and special services ... as part of the IP VPN service.
Prospects of managed services
Managed services include network services such as transshipment, rental and maintenance of equipment, specialized services (remote assistance, training), applications for managing internal features and e-commerce.
In order to provide these services with high quality, service providers need to have specific agreements with customers and must work closely with device manufacturers to design network classes. Applicants require multiple services.
The network layer must be able to meet the requirements of both types of customers: the customer is limited to connecting to his or her ISP through DSL or cable modem and firewall services; and customers are large companies that need to combine ATM, Frame Relay, IP and Ethernet interfaces.
A multi-service network that allows service providers to provide complex services as described above by using a single network can save up to 40% of the cost.
Service providers must provide novel, affordable services that enable them to meet the high level of customer demand.
Multifunctional services include
- VPN Transport: Layer 0 (WDM). Layer 1 (AtoM, ATM, FR, MetroE, L2TP) and Layer 3 (IPSecVPN, MPLS VPN, GRE VPN)
- Internet: Dedicated Internet access, Email, DNS.
- Data center: receiving, archiving, CDN
- Security: firewall, intrusion prevention, virus, encryption, access rights authentication, error checking.
- Video: VOD, broadcast, surveillance, video conferencing.
- Mobile: wireless and terrestrial services.
Next-generation networks (NGNs) not only provide these services, but also provide service providers with the ability to create new services and customers do not need to contact them directly.
The economics of network access
Management of the services provided by NGN is the best way to demonstrate the constant concern of service providers, namely, the increased revenue generated by the provision of services on the same network. , select the modern network structure to minimize the cost of operation, operation and maintenance of the network.
Provided managed services on the NGN network enable the customer service provider and increase revenue. When deciding on the provision of managed services on the NGN, the service provider should consider the services currently provided, the customer base, service coverage, expertise, source financing, and supply partners.
Equipment vendors need to offer a complete package of hardware, software, and accessories in the same family to ensure simplicity in network management and upgrades. In addition, the equipment provider needs to prove to the service provider the business solution in delivering the service to the customer. Service providers need to work in a multi-service network environment to provide a variety of solutions that meet the needs of their customers.
The NGN is a challenge for equipment vendors to introduce new technology and allow carriers to penetrate new services. And the service providers who dare to face the challenge will be the first to make a profit.
