Converged Ethernet/IP networks-which enable voice, data and video to share the same infrastructure-are becoming a reality. They're also changing the rules and requirements for enterprise and service provider networks. To protect delay sensitive voice applications, quality connections, which exhibit very low levels of latency and jitter, are a must. Voice-class availability is also essential, as is an infrastructure that supports truly converged networking. Security is growing importance as well, as networks grow inseparable from an organization's strategic goals and revenue streams. Meanwhile, as networks deliver a more complex mix of applications and services, network management must be become simpler and more straightforward.
In order to meet these business needs, you have to design your network to:
Provide quality connections with low jitter and latency
Achieve voice-class availability throughout the network

The long wait is over. On June 25, the IEEE approved the 802.3z Gigabit Ethernet standard--nearly two years after its birth. With the eagerly anticipated standard ratified, vendors finally can deliver products to satisfy the tremendous interest that's been building for Gigabit Ethernet technology.
These are auspicious times for companies looking for faster network performance. Because of competition among vendors that are steadily increasing their 1000Base-T switch offerings, Gigabit Ethernet is more affordable and easier to deploy than ever. Unfortunately, assessing which Gigabit Ethernet solution is best suited to your needs isn't always easy. Vendors advertise their switches with the customary performance claims and glossy marketing brochures, but neither gives you a definitive idea of how a certain switch will perform in your particular environment, much less how easy it is to set up and manage. To help you get some inkling of what to expect from the latest 1000Base-T switches, I brought some of them into the Windows & .NET Magazine Lab for a test drive.
At the time of writing, at least a dozen vendors offered a wide range of Gigabit Ethernet switches. To narrow the field, I looked only at managed switches that offer native 1000Base-T ports or can accommodate a Gigabit Interface Converter (GBIC) module for uplink ports. I also looked for switches that represent a cross-section of price and functionality. And because I wanted to simulate a typical network-upgrade scenario between a server room and a remote wiring closet, I looked for vendors that could deliver Fast Ethernet to the desktop with 1000Base-T uplinks that I could pair with a 1000Base-T backbone or aggregation switch. My search led me to the most recent Gigabit Ethernet switch offerings from 3Com, Cisco Systems, and Dell. For those looking for a chassis solution, I tested a Hewlett-Packard (HP) chassis switch with Gigabit and Fast Ethernet switch modules.
The testing was fairly simple. I first conducted a baseline test on the Lab network, in which I performed routine administrative tasks (e.g., software-application deployment) while monitoring latency-sensitive streaming-media applications. I next installed Gigabit Ethernet NICs in the network's servers and in some desktop machines and went through the usual regimen of performance tuning. To simulate an upgrade scenario, I then replaced older Fast Ethernet switches in the Lab's test network with each vendor's Gigabit Ethernet offerings. As I worked with each vendor's switches, I noted how easy they were to configure and manage from basic setup to advanced features such as Virtual LAN (VLAN) configuration, routing, and cost-of-service configuration. Finally, I performed the same tasks and ran the same software as I had in the baseline test to check for a performance improvement.

While the IEEE was busy rubber stamping the 802.3z standard, Network Computing was putting Gigabit Ethernet switches and NICs from nearly every Gigabit Ethernet vendor--including Alteon Network, Bay Networks, Cabletron Systems, Cisco Systems, Compaq Computer Corp., Extreme Networks, Hewlett-Packard Co., Intel Corp., Lucent Technologies, ODS Networks, Packet Engines, Silicon Graphics and 3Com Corp.--through one of the most rigorous test suites in the magazine's history.
Our expectations for this review were high. For the switch portion, only products with Gigabit Ethernet interfaces were eligible. We required each vendor to submit two or more units with a total of at least 96 10/100 ports. We put each switch through a battery of tests using Netcom Systems' Smartbits test equipment. Implementing one of the largest test setups we've ever created, we bit-blasted each device to determine how much traffic it could handle. Then we turned off the bit-blasters and focused on performance aspects that affect networks like yours. (For details about our tests, see "Speeds and Feeds," page 76, and "Real World, Real Fibers," page 82.)
We took each vendor's equipment into the wiring closets at the University of Wisconsin at Madison and tested it on real fibers, pushing the distance limitations of Gigabit Ethernet over multimode fiber. After testing each solution in the wiring closet, we moved the products to the labs of Neal Nelson & Associates (1 (312) 755-1000), where we used 96 PC connections to generate more than 5 Gbps of real-world application traffic. We stress-tested each switch for at least 24 consecutive hours using Neal Nelson's (1 (312) 755-1000) LAN benchmark. (For more on the Neal Nelson (1 (312) 755-1000) tests, see "From the Lab of Neal Nelson & Associates (1 (312) 755-1000)" page 88.)
Gigabit Ethernet is a networking technology ten times faster than current 100Mbps networks. Until recently, the high cost of gigabit Ethernet combined with multiple topology standards and the need for fibre optic cables has left gigibit speeds out of reach of home users. Things have changed.
IEEE 802.3ab Recent ‘gigabit over copper’ standards have been adopted that make gigabit Ethernet as easy to use as 100Mbps Ethernet. Gigabit ethernet can now utilize Cat5 or better twisted pair cabling and the same RJ-45 connectors that are used in 10/100Mbps networks. To achieve gigabit speeds, you must use ethernet cable with all 8 wires (four pairs) present. Many inexpensive cat5 Ethernet cables have only 4 wires and can not reach gigabit speeds.
Apple, as usual, is ahead of the rest of the market in bringing gigabit Ethernet to the home. They have put 10/100/1000 base-T network adapters in the PowerMac G4 series computers. Because of the high cost of gigabit Ethernet hubs and switches, Apple has ensured that connection two PowerMac G4’s is as simple as picking up a high quality Ethernet cable. Apples implementation of Gigabit Ethernet needs no crossover cable to connect two computers together. The adapter senses the other Mac and handles the crossover automatically.
Expectations for 2002
I expect the price of gigabit Ethernet to fall dramatically in 2002. I think we will see the price of gigabit Ethernet switched fall to about $40 per port by the end of the year and the price of network cards to fall to around $35 per NIC. I think we will also see gigabit Ethernet incorporated into broadband routers by companies trying to stand out from their competition in this over-crowded router market.
Current Pricing and Products
Asante’ and Addtron appear to be the market leaders in bringing Gigabit Ethernet to the home market. They have both released PCI network adapters that can be purchased for less that $60. Unfortunately, no company has yet released a gigabit Ethernet hub or switch that is within reach of the home network users. Expect to see gigabit Ethernet products on the market soon!
