converged networking and the SAFE Blueprint for VPNs. These deployment models ensure a secure, interoperable, reliable network solution

CONTENT ACCELERATION AND DELIVERY
Cisco 3700 Series enables key services critical to supporting the needs of today’s enterprise networks. By enabling efficient delivery of rich
media and web content, content acceleration and delivery services enhance user productivity while optimizing WAN bandwidth. Cisco 3700
supports the integrated Content Engine Network Module, which leverages the advanced content acceleration features of the Cisco Content
Engine 5xx Series into the industry’s first router-integrated content delivery system.
As enterprises learn to capitalize on the capabilities of web-based applications, HTTP traffic is assuming a larger proportion of WAN
bandwidth. The Content Engine Network Module effectively accelerates applications by optimizing the delivery of bandwidth-intensive and
frequently accessed content. Caching alone can offer a 40-60% savings in WAN bandwidth usage by a branch site, and the content delivery
capabilities of the module enables enterprise services which maximize the productivity and efficiency of a global enterprise. Integration of the
application layer services of the Content Engine Network Module with intelligent network services such as QoS, compression and IPSec offer a
superior bandwidth optimization solution for the enterprise branch.
Combining intelligent caching, content filtering and content delivery capabilities with robust branch office routing helps users optimize their
networks for important branch IP services such as VOIP, while greatly simplifying configuration, deployment, and operation of network
services. Running Cisco Application and Content Networking System (ACNS) software, the Content Engine Network Module enables
customers to extend the value of their branch router infrastructure to deliver strategic new application services—such as Employee Internet
Management, Streaming Media, live and on-demand e-communications and e-learning, with no performance degradation of core routing
services. Further, the Content Engine Network Module interoperates with all Cisco devices, and leverages key Cisco IOS features such as
multicast and WCCP while supporting key management solutions such as CiscoWorks.
INTEGRATION OF FLEXIBLE ROUTING AND LOW DENSITY SWITCHING
The Cisco 3700 Series offers an optional 16-port 10/100 EtherSwitch network module (NM), or an optional 36-port 10/100 EtherSwitch high
density service module (HDSM), both of which leverage the proven Cisco Catalyst technology. The EtherSwitch NM/HDSM hardware
supports 802.1p Layer 2 prioritization, while Cisco IOS supports Layer 3 Diff-Serv and Class of Service (CoS) markings for critical business
data. Coupling Layer 2/3 prioritization techniques, with the QoS for the WAN, the Cisco 3700 Series ensures low latency for critical business
applications, enabling the deployment of e-business applications.
For user authentication, the EtherSwitch network modules support 802.1x.
Optionally, the EtherSwitch ports can also be used to power Cisco IP Phones or the Cisco Aironet Access Points in the low-density-branch to
deliver Wireless LAN (802.11b) access flexibility.
On the 16-port EtherSwitch NM one optional copper Gigabit Ethernet port is available whereas the 36-port EtherSwitch NM provides up to two
optional copper Gigabit Ethernet ports.
The Cisco 3700 Series with the EtherSwitch NM/HDSM integrates Cisco IOS routing and Catalyst switching technologies in a single platform,
offering a single point of management for easier configuration, troubleshooting and a lower total cost of ownership.
Key features include:
• Combination of the industry-leading Cisco IOS features with Catalyst switching technologies for wire-rate Layer 2 switching, with rich
protocol and feature support.
• Integrated platform, with EtherSwitch ports for LAN, WAN flexibility, and a rich QoS toolkit for e-business applications.
