Cisco Certified Expert Network Consulting

As technology advances, the difference between router and switch products is becoming blurred. Essentially, routers are Layer 3 (L3) products designed to connect networks with one another. A typical example is connecting an office Ethernet network to the Internet. Switches are L2 devices that interface client devices that share the same network. Generally, routers depend on processors to send data based on sophisticated algorithms, providing flexibility at the expense of throughput. Switches, on the other hand, depend upon mostly predefined hardware designs to steer data at the fastest possible speed. The current generation of routers usually come with Layer 2 switching capability, and many of today’s switches have some Layer 3 routing capability. Routers developed by Cisco, the source of the vast majority of the world's routers, have improved dramatically in capability and performance and Cisco now makes a comprehensive portfolio that features routers built to meet the needs of users from individual telecommuters to nationwide service providers.

The most recent ISR routers from Cisco have the speed and built-in functionality to support IP voice and video as well as virtual environments while at the same time offering high availability, remote management, seamless expandability, and advanced protection. Cisco's ISR routers enable you to build a firm foundation for an information environment that can grow smoothly as you hire new workers, open extra sites, activate new functions, give access to your network to customers and vendors, and build an expanding mobile user base. Progent’s Cisco CCIE network engineers can provide immediate and economical remote expertise to assist you to select, deploy, administer, upgrade, and support Cisco's most advanced router technology and can assist you to maintain your legacy routers or move efficiently to Cisco’s newer networking solutions.

In contrast to the 1841 router, the 1900 Series ISR G2 routers feature a USB console instead of the outdated DB-9 interface and has an add-in slot for the recently introduced Internal Services Module instead of a slot for the previous and slower AIM module.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 top-of-the-line ISR Generation 2 routers, the 1941 Series ISR G2 routers do not support redundant power supplies or add-in slots for Packet Voice and fax DSP Modules.

Cisco 2900 Series Integrated Services G2 Routers
Cisco 2900 Integrated Services G2 Routers are available in four versions which correspond to the routers in Cisco’s successful 2800 router series. Cisco’s 2901, 2911, 2921, and 2951 Integrated Services G2 routers offer integrated hardware encryption, voice and video ready Digital Signal Processor slots, optional Cisco IOS firewall, Cisco IOS intrusion prevention, voice mail, and from 16 to 50 LAN switches. The on-board encryption hardware provides IPsec and SSL VPN for safe off-site connections and is dramatically faster than the Advanced Integration Modules available with Cisco 2800 routers. The top-of-the-line 2951 Series Integrated Services G2 router supports 600 Session Initiation Protocol sessions. Wired and wireless connectivity alternatives include T1/E1, T3/E3, ADSL and SDSL, plus copper and fiber GbE.
