In-Depth Information
Enterprise branch architectures encompass a wide range of services that customers want
to deploy at the edge of the enterprise. These architectures allow for a variety of connec-
tion options, and distance typically is not an issue. The services in this architecture give
customers new opportunities to increase security, converge their voice and data traffic,
improve productivity, and reduce costs.
The Cisco enterprise branch architecture is a flexible and secure framework for extending
headend application functionality to the remote site. The Cisco enterprise branch architec-
ture uses the Cisco Network Architectures for the Enterprise framework but applies it to a
smaller scale of a branch site.
Common branch network components found within the enterprise framework include
Routers supporting the WAN edge connectivity
■
Switches providing the Ethernet LAN infrastructure
■
Security appliances securing the branch devices
■
Wireless access points (AP) allowing for roaming mobility
■
Call processing providing Unified Communications and video support
■
IP phones and PCs for the end-user devices

Branch Design
It is important to characterize the existing network by gathering requirements to develop a
suitable design for the branch.
Here are some questions you should ask:
How much scalability is expected for (network devices, servers, users)?
■
How much scalability is expected?
■
What level of high availability or redundancy is required?
■
Is a specific server or network protocol support needed?
■
Will the network management or support be centralized or distributed?
■
Are there any network segmentation restrictions, such as DMZ segments, or internal
networks versus external networks?
■
Will wireless services be needed, and to what extent?
■
What is the estimated budget for the branch design?
