1-6 Chapter 1: Routing

Key Features and Benefits

•Modular platform

- The Cisco 3900 Series routers are highly modular platforms with several types of module slots to add

connectivity and services for varied branch-office network requirements.

- The routers offer an industry-leading breadth of LAN and WAN connectivity options through modules to

accommodate field upgrades to future technologies without requiring platform replacement.

- The Cisco SPE on the Cisco 3900 offers the ability to increase the performance of the router with a field-

upgradable motherboard as your network needs grow.

•Processors

- The Cisco 3900 Series routers are powered by high-performance multi-core processors that can

support the growing demands of high-speed WAN connections to the branch office while also running

multiple concurrent services.

• Advanced security with embedded IP Security with Secure Sockets Layer (IPSec/SSL) VPN hardware

acceleration

- Embedded hardware encryption acceleration is enhanced to provide higher scalability, which, combined

with an optional Cisco IOS Software Security license, enables WAN link security and VPN services (both

IPSec and SSL acceleration).

- The onboard encryption hardware outperforms the advanced integration modules (AIMs) of previous

generations.

- The routers support Cisco Easy VPN (remote and server), Dynamic Multipoint VPN (DMVPN), Group

Encrypted VPN (GET VPN), and Secure Socket Layer VPN (SSL VPN). The 3900 Series routers support

Multiprotocol Label Switching (MPLS) VPNs. Specific provider-edge capabilities include Virtual Route

Forwarding (VRF) firewall and VRF IP Security (IPsec).

- More than 3700 intrusion-prevention-system (IPS) signatures are supported in Cisco IOS Software, with

the ability to load and enable selected IPS signatures. More than 4500 IPS signatures are available with

the optional high-performance intrusion-prevention-system (IPS) network module.

- Content Filtering includes URL/keyword blocking and features category-based productivity and security

ratings. This is a subscription-based hosted solution that leverages Trend Micro's global TrendLabs™

threat database, and is closely integrated with Cisco IOS Software.

- Cisco Configuration Professional comes standard on all Cisco 3900 Series Integrated Services Routers.

• WAN Optimization with WAAS Express

- Cisco Wide Area Application Services (WAAS) Express, based on Cisco IOS® Software and integrated

into the Cisco 3900 Series routers offers bandwidth optimization and application acceleration

capabilities in a cost-effective solution

- Fully integrated in Cisco IOS Software, with no additional hardware requirement (the maximum DRAM is

needed in the router). This integration allows significant savings in capital expenditures (CapEx) by

enabling a small-footprint branch-office deployment.

- Increases remote user productivity, reduces WAN bandwidth costs, and offers investment protection by

interoperating with existing Cisco WAAS infrastructure.

- Uniquely provides network transparency, improving deployment flexibility with on-demand service

enablement, and integrating with native Cisco IOS Software services such as security, NetFlow, and

quality of service (QoS).

- Fully interoperable with Cisco WAAS Modules for Services-Ready Engine (SRE) and Cisco WAAS

appliances and can be managed by a common Cisco WAAS Central Manager.

- Offers Context-Aware DRE for reduced latency and increased end-user experience.

- Organizations can enable Cisco WAAS Express as an on-demand service on the router and can expand

to the Cisco WAAS Modules for SRE or a dedicated Cisco WAAS appliance as business needs grow.

• WAN Optimization with Cisco Wide Area Application Services (WAAS) Software on Cisco Integrated

Services Routers Generation 2 (ISR G2)

- Cisco WAAS Software on Cisco 3900 Series provides router-integrated, on-demand WAN optimization

and application acceleration for branch offices.

- Cisco WAAS offers the option to integrate physically with first- and second-generation Cisco ISRs.

- The Cisco Services Ready Engine (SRE) Modules on the ISR G2 platform, which decouple software

services from the underlying hardware, can deliver WAN optimization as an on-demand service as

required for business objectives and IT budget.

- Cisco WAAS Software is licensed with two types of feature capability for deployment on the Cisco SRE

Modules. The software licenses are common across Cisco SRE 700 SM, SRE 710 SM, SRE 900 SM, and

SRE 910 SM.

- Transport license—Supports WAN optimization features including Data Redundancy Elimination

(DRE), Lempel-Ziv (LZ) compression, and Transport Flow Optimization (TFO)

- Enterprise license—Includes Cisco WAAS Transport license functions (Data Redundancy

Elimination (DRE), Lempel-Ziv (LZ) compression, and Transport Flow Optimization (TFO)) plus

application-specific accelerations for protocols including Common Internet File System (CIFS),

Messaging Application Programming Interface (MAPI),

• Multigigabit fabric (MGF)

- The Cisco 3900 Series introduces an innovative MGF that allows for efficient module-to-module

communication, enabling tighter services interactions across modules while reducing the overhead on

the router processor.

• TDM interconnectivity fabric

- Unified communications services in the branch office are significantly enhanced with the use of TDM

interconnectivity fabric in the router architecture, allowing for scaling of DS-0 channel capacity.

• Integrated Gigabit Ethernet ports

- The Cisco 3900 Series provides up to four 10/100/1000 Ethernet WAN ports.

- Two of the 10/100/1000 Ethernet WAN ports on the Cisco 3900 Series can support Small Form-Factor

Pluggable (SFP)-based connectivity in lieu of RJ-45 ports, enabling fiber connectivity.

• High-capacity Packet Voice Video Digital Signal Processor Module (PVDM3)
