Business Drivers for a New Network Framework
A network design must meet the increasingly complex requirements of the organization that it supports
Organisations are looking for:
Techniques to enhance customerrelationships,
Accommodate a mobile workforce and increasing productivity

Business Drivers for a New Network Framework
Looking for ways to integrate emergingtechnologies such as: wireless, virtualization, video etc.
Need for flexible and dynamic networkarchitecture

Business Drivers
Business drivers that can impact network architecture:
Business forces
Technology-related forces
IT challenges
![Page 5: Session 1-2 · Network Design Methodology Understanding the Network Architectures for the Enterprise Identifying Design Requirements Identifying Customer Design Requirements Characterizing](https://reader036.vdocuments.mx/reader036/viewer/2022071012/5fca56b9e70cda4ab521d1c6/html5/thumbnails/5.jpg)
Business forces Return on investment - is it cost
beneficial?
Regulation - Is the companycompliant with the requiredregulations?
Competitiveness - Are wecompetitive enough? How can we bemore competitive? Innovation?

Technology-related forces
Removal of borders – Access to network resources enabled
Virtualization – cost reduction etc
Growth of applications – demandfor new products, service, security at LOWER costs

IT challenges
Network infrastructures are mainly separated into three IT groups:
Data center: Servers and storage networks
Network: Routing, switching, security, and wireless WAN
Applications: Voice and video
Own experience, budget and challenges

Cisco Network Architectures for the Enterprise
Framework to create three architectures for each group that provides for optimization at an individual level and the integration with other areas

Borderless Networks Architecture
Next-generation solution that enables connectivity to anyone and anything, anywhere, and at any time - IOE
Challeges to the network
Security
Reliability
Availability
![Page 10: Session 1-2 · Network Design Methodology Understanding the Network Architectures for the Enterprise Identifying Design Requirements Identifying Customer Design Requirements Characterizing](https://reader036.vdocuments.mx/reader036/viewer/2022071012/5fca56b9e70cda4ab521d1c6/html5/thumbnails/10.jpg)
Borderless network architecture
Four major blocks:• Policy and Control
• Policies are applied to all users and devicesacross the architecture
• Network Services• Services include resiliency and
control• EnergyWise and Medianet
provide capabilities to borderless networks
• User Services• Services include mobility,
performance, and security
• Connection Management• Delivers secure access anytime
and anywhere

Collaboration Architecture
Faster and more complex world that required organizations to change the way they operate
Growing demand for enterprises to:Expand business capabilitiesOperate more efficiently Improve real-time information
accessEnhance user interactions

Collaboration Architecture
Collaboration architecture is composed of three layers:
Communication and Collaboration Applications -The layer contains:
messaging,
Mobileapplications
TelePresence
conferencing
customer care
enterprise social software
IP communications
