Cisco Network Consultants

As technology progresses, the distinction between a router and a switch is becoming fuzzier. At heart, routers are Layer 3 devices designed to connect different networks. A common example is connecting a small business network to the Internet via DSL. Switches are instead Layer 2 (L2) devices that interconnect client devices within a network. Basically, routers rely on processors to send data using sophisticated software, offering flexibility at the cost of speed. Switches, in contrast, rely upon mostly predefined hardware designs to send traffic at the highest feasible rate. Today's routers ordinarily come with Layer 2 switches, and many of today’s switches have Layer 3 routing functionality. Routers developed by Cisco, the supplier of 90% of the industry's routers, have improved significantly in capability and performance and Cisco now offers an extensive portfolio that features routers engineered to handle the requirements of customers ranging from households to nationwide ISPs.

The latest Integrated Services Routers released by Cisco have the speed and integrated functionality to manage IP voice and video as well as virtualization while also offering fault tolerance, remote management, easy expandability, and enhanced protection. These routers enable your company to build a solid basis for an IT network that can evolve seamlessly as you hire more workers, open new offices, deploy new capabilities, give access to your system to customers and partners, and support an an increasingly mobile user base. Progent’s Cisco certified CCIE network consultants can provide fast and affordable remote expertise to help you to plan, configure, manage, upgrade, and support Cisco's latest router technology and can help you to support your older routers or move efficiently to Cisco’s newer networking solutions.

In comparison to previous ISR routers, Cisco's ISR Generation 2 routers feature 2-7 times more performance, far more, and more affordable support. All ISR Generation 2 routers support gigabit switching and incorporate multi-core CPUs and ultra-fast fabric for faster performance. Integrated Services Generation 2 routers also offer smart power control for better energy conservation.

A notable innovation with Integrated Services G2 routers is the IOS Universal image which contains all of the Cisco IOS technology sets so that your company can rapidly license and deploy new services as required without needing to download and transfer a different IOS Software image to yourrouter. Progent's team of Cisco-certified CCIE network engineers can provide world-class expertise to assist your business to design, implement, and support multi-location deployments of Cisco ISR G2 routers that enhance satellite office efficiency and cut the costs of upgrades and maintenance.

Cisco 1900 Series Integrated Services G2 Routers
1900 Series Integrated Services G2 routers offer hardware encryption, optional IOS firewall, Cisco IOS intrusion prevention, and a maximum of 11 modular Ethernet switchports. The Cisco 1941W router provides an WiFi access point that enables cordless connectivity to high-bandwidth data, voice, and video applications via MIMO support that expands coverage for existing 802.11 clients. Interface alternatives for the 1900 Series ISR G2 routers include T1/E1, xDSL, 3G, and 1 GigE.

Compared to the previous 1841 ISR router which they are designed to substitute for, the Cisco 1941 and 1941W ISR G2 routers include 256 MB vs. 32 of flash storage as a default, and this can be expanded to 4GB vs. 128 megabytes. Standard dynamic RAM capacity is 256 megabytes instead of 128 MB and top dynamic RAM capacity is 2.25 GB instead of 384 MB. In contrast to the 1841 router, the 1900 Integrated Services G2 routers include a USB console in place of the older DB-9 interface and includes a slot for the recently introduced ISM module instead of a slot for the previous and slower Advanced Integration Module. Unlike top-of-the-line ISR G2 routers, the Cisco 1941 and 1941W Integrated Services G2 routers do not allow redundant power supplies or slots for PVDM modules.

2900 Series ISR G2 Routers
Cisco 2900 Series Integrated Services G2 Routers are released in four models which are intended as upgrades to the models in Cisco’s popular 2800 router family. Cisco’s 2901, 2911, 2921, and 2951 ISR G2 routers offer integrated hardware encryption, voice and video ready DSP slots, optional Cisco IOS firewall, Cisco IOS intrusion prevention, call processing, and from 16 up to 50 modular LAN switchports. The on-board encryption circuitry provides IPsec and Secure Sockets Layer VPN tunneling for protected remote access and is dramatically higher performing than the Advanced Integration Modules available with 2800 series routers. The top-of-the-line Cisco 2951 Series Integrated Services G2 router can handle 600 SIP sessions. Wired and wireless connectivity alternatives include T1/E1, T3/E3, ADSL and SDSL, as well as Gigabit Ethernet.

Cisco 2900 Series Integrated Services G2 routers accommodate Cisco’s Enhanced EtherSwitch Service Modules, providing high-performance features identical to the Catalyst 2960 and 3650-E Series Switches.
