IBM, Cisco help networks help themselve

IBM Corp. and Cisco Systems Inc. want to make it easier to diagnose and solve problems in an enterprise's IT infrastructure, even to the point where it can do that by itself.

Pinpointing the causes of failures and solving the root problems takes up a lot of IT staff time, a resource that has become more scarce as budgets tighten, according to the companies, which announced a drive toward self-diagnostic and self-healing networks on Friday. The combination of networks and systems is also becoming more complex, so simplifying and automating that process is increasingly important, they said.

Self-diagnosis and self-healing are key parts of IBM's broader autonomic computing initiative, aimed at creating systems and networks that in many respects run themselves, said Ric Telford, director of architecture and technology in the autonomic computing business of Armonk, New York-based IBM. Companies can never remove the human administrator from the picture completely, but Cisco and IBM's steps should make life easier even when people have to get involved, he said.

For example, if a transaction goes wrong, the cause might lie in any one of many applications or devices that come into play across the infrastructure, Telford said. Narrowing it down can be hard.

"The growing complexity of infrastructure is causing more and more of these hard-to-diagnose problems," he said.

Initial aims of IBM's and Cisco's program include coming up with a common way for parts of the system to log events and providing software for an administrator to see and analyze problems. The two companies plan to offer these and other technologies over time, but they also are making all the technology available openly to other players and will seek to have it adopted by industry standards bodies, Telford said.

Between technical and political disagreements, it's unlikely all vendors will sign on with the two vendors' approach, but even having coordination among some systems should save IS departments time and money, said Amy Wohl, an industry analyst at Wohl Associates, in Narberth, Pennsylvania.

"It's unrealistic to think that anything new is going to cover every single thing," Wohl said.

The IBM-developed Common Base Event (CBE) specification defines a standard format for event logs, which devices and software use to keep track of transactions and other activity.

All the components of systems typically have different formats for the information they collect about events, Telford said. For example, if an IS team needs to figure out where something went wrong with an e-business application, they may need to understand 40 different event log formats, he said. Root cause analysis of the problem could require several different administrators -- database, network and so on -- getting involved.

As a common format, CBE can simplify that process, Telford said. Future products should use CBE as their native log format, but "log adapters" can define mappings between current proprietary log formats and CBE, he said. IBM now has a team of about 24 engineers developing log adapters for core IBM products, including hardware, software and storage products, according to the company.

In August, IBM proposed CBE as a standard to the Organization for the Advancement of Structured Information Standards (OASIS), Telford said.

Configure your home wireless network

2011-09-07T09:21:00.000-07:00

You can use a wireless network (WLAN) to share Internet access, files, printers, game consoles, and other devices among all the computers in your home. After you’ve completed the initial wireless router setup and added your computers and devices to the network, you can use your home network to surf the web or to play online games—whether you're sitting in your living room or relaxing in your backyard.

It's easier than ever to set up a wireless network, especially now that Internet access and routers (like Linksys wireless routers and D-link wireless routers) have become widely available.
What you’ll need to set up your wireless network

An operating system that supports wireless networking
The Windows 7 operating system fully supports wireless networking. For Windows Vista users, we recommend installing Windows Vista Service Pack 2 before setting up your wireless network. For Windows XP users, we recommend installing Windows XP Service Pack 3. Use Windows Update to check whether you need the service pack and to install it. Click the Start button, click All Programs, click Windows Update, and then click Check for updates. Although the service packs for Windows Vista and Windows XP are not required for wireless networking, they can make things much easier and can help protect you against hackers, worms, and other Internet intruders.

A broadband (DSL or cable) Internet connection
To set up a wireless network, you need a broadband or high-speed Internet connection (not a dial-up connection) provided by an Internet service provider (ISP), usually for a monthly fee. Two common broadband technologies are Digital Subscriber Line (DSL) and cable technology. These require a DSL modem or a cable modem (often provided by your ISP). After you have an ISP and a modem, you're ready to connect to the Internet.

Set up a new connection to the Internet:

Windows 7 and Windows Vista

Windows XP

A wireless router, a DSL modem, or a cable modem with built-in wireless networking support
The router converts the signals coming across your Internet connection into a wireless broadcast, sort of like a cordless phone base station. Newer DSL and cable modems come with integrated wireless networking capability and are called modem routers. If the modem router you received or purchased from your ISP already has wireless capability built in, you do not need to purchase a separate wireless router. Just follow the instructions provided by your ISP for activating your wireless connection.

If you do need to purchase a wireless router, be sure that you buy a wireless router and not a wireless access point. The Linksys router is a popular router for wireless networks because it’s simple to set up.

While you're looking for a wireless router or other wireless equipment in stores or on the Internet, you might notice that you can choose equipment that supports four different wireless networking technologies: 802.11a, 802.11b, 802.11g, and 802.11n. We recommend 802.11g (Wireless-G) or 802.11n (Wireless-N) because they offer excellent performance and are compatible with almost everything.

NOTE: If you do not want to buy a wireless router or if you want to connect computers or devices temporarily for a specific purpose, like sharing devices or games, you can set up a temporary wireless network without a router. This is called an ad hoc network.

Set up an ad hoc network:

Windows 7

Windows Vista

Windows XP

A computer with built-in wireless networking support or a wireless network adapter
If you have a newer computer, you may already have built-in wireless capabilities. If this is the case, you don’t need a wireless network adapter. Here’s how to check whether your computer has wireless support installed:

Windows 7 and Windows Vista

Windows XP

If your desktop or laptop computer does not have built-in wireless support, you need to purchase a network adapter to wirelessly connect your computer to your wireless router. If you need an adapter for a desktop computer, buy a USB wireless network adapter. If you have a laptop, buy a PC card-based network adapter. Make sure that you have one adapter for every computer on your network.

NOTE: To make setup easy, choose a network adapter made by the same vendor that made your wireless router. For example, if you find a good price on a Linksys router, choose a Linksys network adapter to go with it. To make shopping even easier, buy a bundle, such as those available from Linksys, Actiontec, D-Link, Netgear, Microsoft, and Buffalo. If you have a desktop computer, make sure that you have an available USB port where you can plug in the wireless network adapter. If you don't have any open USB ports, buy a USB hub to add additional ports.

A copy of your router setup instructions
Before you begin setting up your wireless network, it’s a good idea to make sure that you have the copy of the setup instructions provided by the router manufacturer or your ISP. If you do not have a copy, visit the manufacturer’s website for get instructions on how to set up your router. All routers vary, and you may need to consult the instructions to set up your wireless network using your specific router.
After you have everything you need, follow these five steps to set up your wireless network.

1. Connect to the Internet

Make sure that your Internet connection and your DSL or cable modem are working. Your wireless network depends on this connection.

2. Connect your wireless router

These are the steps for connecting a stand-alone wireless router to your DSL modem or cable modem. If you have a modem router, follow your ISP’s instructions for connecting your network.

Since you'll be temporarily disconnected from the Internet, print these instructions before you go any further.

First, locate your cable modem or DSL modem and unplug it to turn it off.

Next, connect your wireless router to your modem. Your modem should stay connected directly to the Internet. Later, after you've hooked everything up, your computer will wirelessly connect to your router, and the router will send communications through your modem to the Internet.

Next, connect your router to your modem:

Note: The instructions below apply to a Linksys wireless router. The ports on your router may be labeled differently, and the images may look different on your router. Check the documentation that came with your equipment for additional assistance. Or do a Bing search on “[your manufacturer/model] wireless router setup” to find images and instructions.

If you currently have your computer connected directly to your modem: Unplug the network cable from the back of your computer, and plug it into the port labeled Internet, WAN, or WLAN on the back of your router.

If you do not currently have a computer connected to the Internet: Plug one end of a network cable (included with your router) into your modem, and plug the other end of the network cable into the Internet, WAN, or WLAN port on your wireless router.

If you currently have your computer connected to a router: Unplug the network cable connected to the Internet, WAN, or WLAN port from your current router, and plug this end of the cable into the Internet, WAN, or WLAN port on your wireless router. Then, unplug any other network cables, and plug them into the available ports on your wireless router. You no longer need your original router, because your new wireless router replaces it.

Next, plug in and turn on your cable or DSL modem. Wait a few minutes to give it time to connect to the Internet, and then plug in and turn on your wireless router. After a minute, the Internet, WAN, or WLAN light on your wireless router should light up, indicating that it has successfully connected to your modem.

3. Configure your wireless router

Using the network cable that came with your wireless router, you should temporarily connect your computer to one of the open network ports on your wireless router (any port that isn't labeled Internet, WAN, or WLAN). If you need to, turn your computer on. It should automatically connect to your router.

Next, open Internet Explorer and type in the URL or address to configure your router.

NOTE: Do this on the computer that you are using to set up your wireless network. The computer automatically links you to the router’s page. If you type the router’s URL on a different computer, typing the address in the navigation bar will not take you to your router’s configuration page.

On the router configuration page, you might be prompted for a password. The address and password you use varies depending on what type of router you have, so refer to the instructions included with your router or on the manufacturer’s website.

For quick reference, this table shows the default addresses, user names, and passwords for some common router manufacturers. If the address is not listed here, you can read the documentation that came with your router or go to the manufacturer's webpage to find it. There may be multiple website addresses you can use.
