Modular Network Design

Modules

Campus

Operating center of an enterprise.

This module is where most users access the network.

Combines a core infrastructure of intelligent switching and routing with mobility, and advanced security.

Data Center

Redundant data centers provide backup and application replication.

Network and devices offer server and application load balancing to maximize performance.

Allows the enterprise to scale without major changes to the infrastructure.

Can be located either at the campus as a server farm and/or at a remote facility.

Branch

Allows enterprises to extend head-office applications and services to remote locations and users or to a small group of branches.

Provides secure access to voice, mission-critical data, and video applications.

Should provide a robust architecture with high levels of resilience for all the branch offices.

WAN and MAN

Offers the convergence of voice, video, and data services.

Enables the enterprise a cost-effectively presence in large geographic areas.

QoS, granular service levels, and comprehensive encryption options help ensure the secure delivery to all sites.

Security is provided with multiservice VPNs (IPsec and MPLS) over Layer 2 or Layer 3 communications.

Remote User

Allows enterprises to securely deliver voice and data services to a remote small office/home office (SOHO) over a standard broadband access service.

Allows a secure log in to the network over a VPN and access to authorized applications and services.
