Challenges in the Enterprise Network Today Today’s enterprise:

Changes can break something or open a security gap!

Core

Scale – Multiple points of the network are replicated over an over and over again to provide scale

Complexity – We still implement multiple layers in the network using a three tier design with L2 Vlan’s everywhere

Reliability – multiple single points of failure can exist either from a physical or virtual point of view

Core

Adds, moves and changes difficult to co-ordinate, keep track off and implement on mass

Cumbersome to rapidly deploy and change at speed and troubleshooting applications and users can be equally challenging

Support and licensing costs based on single boxes adding to an every increasing CAPEX and OPEX

WANCore Layer: • L3 Central Point• Multi-10GbE

Distribution Layer: • L2 demarcation between L2 & L3• Aggregation point for Access

Layer

Access Layer: • PoE, 10/100/1000Mbps• Stacks/VC for pockets of single

management

Traditional Campus

WAN

Core Layer: • Becomes your aggregation layer

or AD for the whole network• It also becomes your central

point of management of the whole network

• Every device attached to aggregation layer becomes a line card or satellite device

• Licensing is centralised to the two AD’s but SD’s inherit the AD’s license capabilities

Core Layer

WAN

Distribution Layer: • Can become a AD for the

building it is located in or a SD of the core

• If a AD, then licensing is placed here for all SD attached

• Software images are stored in the AD to distribute to SD’s

• Local or centralised switching or routing

• Or collapse the distribution layer in to the core

Distribution Layer

WAN

Access Layer: • Smaller Linux image• Multiple images per a switch• Different code versions

supported• Local or central switching• License inherited from AD• Support individual or stack

switches

Access Layer

WAN

• Simply clusters based on a single building or floor

• Single virtual Switches covering up to 6000 ports or 128 devices

• Single point of management and control

Fusion Campus – Option 1

WAN

• Single cluster across whole campus

• Single virtual Switches covering up to 6000 ports or 128 devices

• Single point of management and control
