Some Current Routers
|A Brief Survey.
This page presents a variety of the routers available from different
companies. While there are many others I hope this will give you
Linksys has a reputation, at least with me, of providing some of the
best networking equipment for the home or small business user.
They were actually acquired by Cisco, which seemed to me to be an
Linksys is known to have models that combine many different capabilities such as routing, switching and firewall capabilities into a single model. It should make sense that intelligent home users would like to get these sorts of capabilities at reasonable prices.
The following table gives a very brief survey of some of the Linksys routers.
|BEFSR11||EtherFast Cable/DSL Router - option to connect multiple PCs to a high-speed Broadband Internet connection or to an Ethernet back-bone. Allowing up to 253 users, the built-in NAT technology acts as a firewall protecting your internal network. It can also be configured as a DHCP server.|
|BEFSR41/BEFSR81||EtherFast® Cable/DSL Router with 4-Port or 8-Port Switch - is a kind of "splitter" for your Internet connection. Connect a DSL or Cable Modem to the Router, and all the computers in your household can share the Internet -- all at the same time. The built-in switch lets you attach local PCs directly, or daisy-chain out to more hubs and switches as your network grows.|
The Linksys Instant Broadband™ EtherFast®Cable/DSL Firewall Router with 4-Port Switch/VPN Endpoint - the perfect solution for connecting a small group of PCs to a high-speed broadband Internet connection or a 10/100 Ethernet backbone.
|RVO42/RVO82||The Linksys 10/100 4-Port or 8-Port VPN
Router - Let multiple computers in your office share an Internet
connection. Dual Internet ports on the 10/100 these VPN Routers let you
connect a second Internet line as a backup to insure that you're never
disconnected. Or, use both Internet ports at the same time, and let the
router balance your office's requirements between them for maximum
The 10/100 VPN Router also features a built-in full-duplex 10/100 Ethernet switch to connect PCs directly, or you can connect more hubs and switches to create as big a network as you need.
Cisco routers used to be classified in three major categories.
The following table outlines CISCO product offerings. Remember the term series means a chassis that is variously configured at the plant into different product models usually most determined by their particular printed circuits cards. Unfortunately, these are likely to be at least somewhat outdated.
|Cisco SOHO Routers|
|Cisco 77||DSL access router to connect multiple users. Includes user configurable IOS.|
|Cisco 600 Series||DSL access router for a single. Doesn't have user configurable IOS.|
|Cisco 700 Series||ISDN access routers to connect up to 30 users. Doesn't have user configurable IOS.|
|Cisco 800 Series||ISDN, DSL and serial access routers to connect up to 20 users. Includes IOS and has VPN encryption capability.|
|Cisco uBR900 Series||Integrated VoIP, VPN, and router functionality for telecommuters and small offices. Includes user configurable IOS.|
Small to medium sized networks require a wide variety of solution
approaches largely based on capacity needs and type of telecom link.
The following table outlines CISCO product offerings. Various combinations of LAN technologies and WAN media can be configured. Modular means that the chassis can be upgraded on-site by inserting one or more modules. Non-modular devices are fixed in configuration when assembled.
|Cisco Midrange Routers|
|Cisco 1000 Series||Ethernet access router to connect to either an ISDN or a serial WAN link.|
|Cisco 1400 Router||Ethernet access router to connect to either an ATM or a DSL trunk.|
|Cisco 1600 Series||Ethernet access router to connect to either an ISDN or a serial WAN link. Includes VPN encryption ability.|
|Cisco 1700 Series||Ethernet access router to connect to a broadband, ISDN, or DSL WAN link. Includes VPN encryption ability. Also includes VoIP and VoFR capability.|
|Cisco 2500 Series||Ethernet or Token Ring router/hub or dial access server models to connect one or two LAN segments to an ISDN or serial link.|
|Cisco 2600 Series||Modular and cost-effective solution for duty as access router, voice/data gateway, or dial access server. Connects one or two Ethernet or Token Ring LANs to ISDN, channelized T1, Ethernet, analog modems or ATM links. Also supports voice/fax and Frame Relay.|
|Cisco 3600 Series||Modular high-density router for dial access or router-to-router traffic. Supports ISDN, serial, channelized T1, digital modems and ATM links. Also supports voice/fax and Frame Relay.|
These models allow CISCO to make the claim that over 70% of the Internet
is run using its routers. The bigger routers actually resemble
dorm refrigerators and have data buses which accept blades
- whole devices on boards. Because they aren't access
routers they can handle as many users as they can handle packets.
All of these products are modular and can operate more than one protocol
simultaneously. A slot is an
electronic bay into which a printed circuit board can be installed.
The following table outlines CISCO backbone product offerings.
|Cisco Backbone Routers|
|Cisco 4000 Series||Three slot routers supporting Ethernet, Fast Ethernet, Token Ring, FDDI, HSSI, serial, channelized T1 and ATM.|

|Cisco 10000 Series||Ten slot Gigabit Ethernet switch router. Has special card for OC-12 WAN link. Offers IPSec, MPLS VPN and QoS (Quality of Service) capabilities.|
|Cisco 12000 Series||Eight or twelve slot Gigabit Ethernet switch router optimized for IP. Has special cards for OC-12 and OC-48 WAN links.|
|Cisco uBR7200 Series||Two to four slot broadband, carrier class routers. It's designed for cable operators and service providers. This series connects residential subscribers for high speed data, broadband and IP telephony.|

Rich set of ATM interfaces & capabilities for network transformation
Now we will spend some time surveying some 3-Com
routers. An important link for their United States operations is
The last I knew, 3Com was focusing only on larger business and service provider equipment. But last I knew they were in pretty serious financial trouble even though they have a very good reputation for quality products! So one must look at Linksys and Cisco's decision to acquire them. But, in and of itself, this really isn't sufficient to describe why 3Com has been struggling (last I knew).
