Section 3.0 WAN Implementation Issues Section 4.0 Conclusion Section 5.0 List of References Intense competition is expected in the information networking arena over the next 5-10 years. As the competition increases, it will be essential for companies to position themselves appropriately to take advantage of their core competencies and to prepare for the emerging telecommunications environment. In this competitive environment, mergers, alliances, and the onslaught of new entrants into the market have service providers struggling to find innovative ways to retain and/or attract the most lucrative subscribers. Today’s service providers are striving to differentiate themselves within this expanding competitive landscape by searching for ways to brand and bundle new services, achieve operational cost reductions, and strategically position themselves in relation to their competition. As Figure 1 illustrates, the top 15% of today’s residential Subscribers in the US are said to account for about 95% of carrier profits! Thus, many service providers are looking to Next Generation Network (NGN) services as a means to attract and/or retain the most lucrative customers.

 * 1.0 Introduction – Next Generation Network **



Internet world-wide community already got thousand of smart PCs, software and hardware were extremely good enough to handle an application either its online or offline. All we need from the public of network carriers is reliable and high-bandwidth transport. The reason why we need Next Generation Network is because: 1. The Service provider’s business is increasingly become a commodity business. They are being forced to compete by price for ever-shrinking profit margins. In the mean time, competitors are offering more sophisticated services to skim off the incumbent high-margin customers. If the public network carriers want to prosper in the new millennium, they must find ways to add value to their transport services. Next Generation Network advance skill will help them to retain their key customer and expend their addressable markets into new areas. 2. The major thrust of traditional network service providers has been to offer the mass market basic transport of information between end users, with various value-added capabilities. These services tended to involve narrowband voice calls, with a single point-to-point connection per call. However, this view of services is rapidly changing as the world’s economies are becoming increasingly reliant on information as a basic resource. 3. Most traditional service relate to basic access/transport/routing/switching services/basic connectivity/resource and session control services. Next Generation Network will enable a much boarder array of service type, including : Ø Specialized resource service. Ø Processing and storage service. Ø Middleware service. Ø Application-specific service. Ø Content provision service that provide or broker information content. Ø Internetworking service for interaction with other types of applications, services, networks, protocols, or formats. Ø Management services to maintain operate, and mange communications/ computing network and services. The current evolution of telecommunication services point to a world service of providers will have the flexibility to focus on micro-marketing. Decisions about their service offering may have as much to do with packaging, as they will with the actual service offered. As multiple carriers, service provider, equipment vendors, and other business entities all become involved in providing service to end user, federated network and business system will become increasingly important. The service is about: Ø Multimedia services – allow multiple parties to interact using voice, video and data. Ø Data (Connectivity) services – allows for real-time establishment of connectivity between endpoint, along with various value-added features. Ø Unified Messaging – support the delivery of voice mail, email, fax mail, and pages through common interface. Ø Information brokering – involves advertising, finding and providing information to match consumers with providers. Ø E-Commerce – allow consumers to purchase goods and services electronically over the network. Next Generation Networks are based on Internet technologies including Internet Protocol (IP) and Multiprotocol Label Switching (MPLS). For voice applications one of the most important devices in NGN is a Softswitch - a programmable device that controls Voice over IP (VoIP) calls. In a NGN there is a more defined separation between the transport (connectivity) portion of the network and the services that run on top of that transport. This means that whenever a provider wants to enable a new service, they can do so by defining it directly at the service layer without considering the transport layer - i.e. services are independent of transport details. Increasingly applications, including voice, will tend to be independent of the access network (de-layering of network and applications)
