Evolution of networks
 First generation networks
designed based on copper-based transmission
medium
example, like Ethernet & Token Ring
disadvantage: each node has to inspect
whether incoming information meant for it
fiber is not used
3
Evolution of networks (continue…)
 Second generation networks
copper replaced by fiber
achieved higher bit rate, longer distance and
higher reliability
higher network throughput due to higher
transmission rates
still use traditional architectures
disadvantage: nodes still have to process
information intended for other nodes
4
Evolution of networks (continue…)
 Third generation networks
exploit unique features of fiber, like huge spectral
bandwidth and the low propagation loss
employ lightwave techniques
carriers in multiple high capacity channels, which
can be individually configured
very high network throughput
termed as all optical networks (AON)

Consumer Needs Are Evolving Beyond Connectivity:
Requires Integrated Voice / Video / Data with Mobility
Physical and Social Context Determines
the Application Mix Used
Home Office / VPN
Online Gaming
IM / Group Chat
Internet Access
IPTV/VoD
IP NGN Infrastructure
 Subscriber Personalization:
Actively manage the subscribers identity and adjust the service
offering/packaging (i.e., different identity in different worlds)
 Mass Scalability:
Leverage mass-customization principles:
Service-bundling; subscriber-grouping and per-group processing
 Service Evolution:
From transport-based service models (time/distance/volume) to
content-based service models

Business Needs Are Evolving Beyond Connectivity:
Requires Highly Available, Secure Managed Services
Helping Businesses Reduce Cost / Free
Resources to Focus on Core Competency
Collaboration
Convergence
Web Services
Applications
Storage/Computing
IP NGN Infrastructure
 High Availability:
Managed networks can help ensure business continuity in the face of
everyday interruptions and unexpected disasters
 Application Awareness:
Allows operators to classify applications, apply application-specific QoS
policies while metering / billing for services on a converged network
 Service Security:
Providing firewalls and intrusion detection systems (and keeping them
updated) and using encryption for all sensitive data

Transition to IPNGN

Application convergence
– Integration of new service over broad band

Service Convergence
– Service continuity across

Network convergence
– Eliminate layers in Network for CapEx efficiencies

Issues and Challenges in the Next Generation
Network
1.
Mobility Services Management
 Device Roaming
 Service mobility
 User mobility
2.
Inter Operability Frame Work
 Inter working – WiFi Mesh open Interface that offer flexibility to Service
Provider
 Inter working existing Network
3.
Access independent Service Control
4.
Traffic engineering Issues
5.
Routing Service/Protocol
6.
QoS
 All kind of Service over all kind of medias
 Decoupling Services from Network
7.
Security
 DDoS Protection
 Virus Filtering
