of the network.

High network availability—A Cisco network helps ensure the
reliable network access and maximum uptime that companies
depend on to support new users, open new offices, deploy new
services, extend their networks to customers and partners,
support a more mobile workforce, and more. Cisco switches and
routers include support for network and link redundancy, dynamic
routing, automatic failover, and redundant power for improved
fault tolerance and network availability.

Predictable performance—Intelligent end-to-end management
maximizes the availability and performance of critical applications.
Cost-conscious small and medium-sized businesses (SMBs) can
maximize WAN bandwidth to serve more users and conduct
more business over

Cost-effectiveness—An end-to-end solution approach reduces
complexity and network management costs. Modular and
scalable products help reduce costs of future expansion.
