encrypted, VPN traffic
• Delivers high WAN throughput while also
running firewall, QoS, IPS and other services
• Modular design, supports an array of plug-ins,
including WAN-interfaces and switch modules
• Various security options including Dynamic
Multipoint VPN (DMVPN), Easy VPN server

configuration, operational and performance aspects of its new,
modular 1841 Integrated Services Router.
The Cisco 1841 represents a next-generation evolution of the Cisco
1721 router. The Cisco 1841 is designed to deliver multiple services –
including stateful firewall, VPN tunneling and encryption, and intrusion
prevention system (IPS) in a single compact chassis. Also, various
optional modules can augment the system’s feature and service
repertoire and/or performance. For example, while the 1841 comes
with an on-board hardware crypto processor that provides VPN
acceleration using an optional IOS security image, encryption
performance can be further increased with an Advanced Integration
Module (AIM), as was the case in this test bed.
The 1841 ran a late-beta version of IOS 12.3(11)T in the test bed.
Miercom verified that, while running various additional services (see
table on page 3), the 1841 could sustain a bi-directional, E1-capacity
IP WAN link, with a 3DES-encrypted, mixed traffic load (see below).
This router is designed to deliver security and data services
concurrently at full T1/E1 rates.

throughput of nearly 2 Mbps over an E1 IP-WAN link. All data was QoS-
classified, 3DES-encrypted and secured through Cisco’s Dynamic Multi-
point VPN (DMVPN). The red line shows the max theoretical link capacity.
