Cisco Expert Network Consultants

As computer technology advances, the distinction between router and switch products has grown less clear. Fundamentally, routers are Layer 3 (L3) devices that connect networks with one another. A common example is connecting a small business Ethernet network to the Internet. Switches are instead L2 devices that interface various devices that share the same network. Basically, routers depend on computation to forward data based on sophisticated software, providing intelligence at the cost of speed. Switches, by comparison, depend upon mostly fixed hardware designs to steer data at the highest possible rate. Today's routers usually incorporate Layer 2 switching capability, and many modern switches include L3 routing functionality. Routers developed by Cisco, the producer of the vast majority of the world's routers, have advanced significantly in function and performance and Cisco now offers a comprehensive portfolio that includes routers designed to handle the requirements of customers from individual telecommuters to nationwide service providers.

The most recent ISR routers released by Cisco have the performance and built-in features to support IP voice and video as well as virtual environments while also providing high availability, remote management, easy scalability, and enhanced protection. Cisco's ISR routers enable your company to establish a firm basis for an IT environment that can evolve smoothly as you hire more workers, establish extra offices, configure new functions, extend your network to customers and partners, and support an expanding mobile user base. Progent’s Cisco certified CCIE network consultants can provide immediate and economical online support to help you to select, configure, manage, upgrade, and troubleshoot Cisco's most advanced router technology and can help you to support your older routers or migrate non-disruptively to Cisco’s newer router solutions.

Default dynamic RAM capacity is 256 MB instead of 128 and top DRAM capacity is 2.25 gigabytes compared to 384 MB. In contrast to the 1841 router, the 1900 Series Integrated Services G2 routers feature a USB console instead of the older DB-9 interface and has an add-in slot for the recently introduced Internal Services Module instead of a slot for the previous and slower AIM module. In contrast to higher end Integrated Services G2 routers, the 1941 Series ISR G2 routers do not support redundant power supplies or slots for Packet Voice and fax DSP Modules.

2900 Series ISR G2 Routers
Cisco 2900 Integrated Services G2 Routers are released in four versions which correspond to the models in Cisco’s successful 2800 router series. Cisco’s 2900 ISR G2 routers include integrated hardware encryption acceleration, voice and video capable Digital Signal Processor slots, optional firewall, IOS intrusion prevention, call processing, and from 16 to 50 modular Ethernet switches. The integrated encryption circuitry supports IP Security and SSL VPN tunneling for safe remote access and is dramatically faster than the AIM modules available with Cisco 2800 routers. The high-end 2951 Series Integrated Services G2 router supports 600 Session Initiation Protocol sessions. Connectivity options include T1/E1, T3/E3, ADSL and SDSL, as well as GbE.
