Managing Business-Grade Services and Systems on Cisco
IP Next-Generation Networks

Executive Overview

Through subscriber interactions at customer touch points, the Cisco

IP Next-Generation Network

(IP NGN) management framework enhances, accelerates, and helps enable service providers to

gain competitive advantage, delivering the desired level of customer experience. When enterprise

customers subscribe to business-grade services from service providers, they experience what it is

like to deal with that provider and form an opinion, good, bad, or indifferent. This experience is the

ultimate conveyor of value to the customer and a primary influence on future behavior. The quality

and consistency of that experience is fundamental to driving future loyalty or accelerating

defection.

Demand for bandwidth in the metropolitan-area network (MAN or metro) is expanding

exponentially, the result of myriad factors, including data-intensive applications, new business

models that rely on the Internet, the growth of broadband services, distributed applications, Web

services, IP convergence, streaming content, multimedia, new computing models, networked

storage, and business continuity initiatives. Service providers can take advantage of Metro

Ethernet to deliver Ethernet connectivity services using Layer 1 or Layer 2 transport and access to

value-added Layer 3 services. Ethernet connectivity services provide a scalable, cost-effective

solution to meet requirements for high-bandwidth, enterprise WANs and MANs. Users can

implement them over existing optical, Gigabit Ethernet, IP, and Multiprotocol Label Switching

(MPLS) infrastructures to create a VPN service.

Networks are like human DNA: they are unique, with a multivendor, multitechnology, multiservice

environment. Service providers’ networks must evolve and adapt, reducing time to market to

deliver and manage convergence (technology, platform, software, form factor, process, user

interface, and mindset) and divergence (terminal, bandwidth and content).

The Cisco IP NGN management framework includes a virtual network layer, open and extensible

APIs, a common information model for real-time dynamic policy management based on events

from multiple sources, and control to accelerate services deployment. Service provider strategies

include acceleration of convergence to reduce ongoing operating expenses (OpEx) and capital

expenditures (CapEx), while increasing addressable market divergence of revenue and brand

value. There are several types of concurrent convergence and divergence:

●

Convergence:

◦

Technology: Telecommunications is clearly converging toward increasingly IP-based

solutions.

◦

Platform: Trend of integrating features that used to exist in separate pieces of equipment

into a single piece of equipment has become a service provider expectation and

preference.

◦

Software: Standardized and common software platforms are becoming an increasingly

important part of telecom networks.
