Wireless channel architecture

Nogirs — Mon, 16 May 2011 17:47:30 +0000

In your article of designing 802.11n, you state ‘Channel architecture: Nearly all products use multiple channels to create micro-cells,
but at least two vendors use a single channel to create one big RF layer. The latter clearly cuts
roam time when clients move, but trade-offs are hotly debated.’

What are teh trade-offs that are hotly debated and where can I find articles to read? Thanks (enjoy your articles and tips)

Whole IT revamp

Mohammed Anwar — Fri, 01 Feb 2008 07:38:47 +0000

My company is planning to revamp whole IT structure. I request your advice and suggestions on how to go about it.

First let me describe the present IT structure:

country A
Forest Server with Exchange Server 2003 and services on separate servers;
domain name compnay.com

There are number of sites in that country with ADCs connected via VPN.
like dc11.company.com, dc12.company.com………..

Country B (C, D, E and so on)
New Domain Tree in an existing forest and one exchange Server;
company.co.in (co.id, co.kl and so on)

Similarly this country also has number of sites with ADCs connected via VPN / MPLS.
like dc11.company.co.in, dc12.company.co.in……….

All Exchange Servers scattered in different countries are in same Exchange organization (country A).

Now my company is planning to change IT structure as:
Esatblished new ADS in another Country say country Z as companynew.com along with new Exchange 2007 Server.

A Disaster Recover (DR) site in country Y. No more additional exchange Servers like in present scenario.

All the domains will be demoted from existing domains and promoted to new domain.

All mails from different Servers will be merged with new server.

I need advice what could be the best possible way of achieving following:
1. Creation of new site and DR site in different country including failove etc.
2. Merging e-mails from different exchange servers to one server.
3. Interconnectivity
4. Any other things which you want to share in this regard.

Your suggestion will be good for us in our implementation.

Thanks

Anwar Zahoor

Uploads bringing network down

Kaiserbeto — Fri, 05 Aug 2005 09:59:31 +0000

We do web design so the volume of traffic going out to our live production servers is considerably high at times. So my question is, without upgrading our hardware (see below), is there any way to stop uploads from bringing the entire network to its knees?

I’ve got a small LAN that has between 30 and 35 users on it at a given time.
All equipment was purchased before I arrived and not likely to change.
We are on a 6Mbps DL/ 684k upload DSL line.
I’ve got a Watchguard x700 firebox (older model, not new version) that acts as our router / firewall. Does not have traffic prioritization, load balancing, etc.
Our primary office switch that connects to the Firebox and Primary file server is a Linksys SR2024 gigabit.
The rest of the office has 100 mb switches and a mix of 100 and 1000 base NIC’s running on XP and Tiger machines.

Help with IBM ds6800 storage array. can’t assign storage unit to complex.

Japeters — Thu, 04 Aug 2005 16:01:31 +0000

Getting a message that says the storage management console server can not be contacted. we’ve never installed one of these before, but been to IBM training on it. training was uselsess for implementation from scratch. has anyone done one of these and can tell me where we are going wrong? will be very appreciative…..

SMTP routing groups

Sbusiso — Mon, 25 Jul 2005 04:41:18 +0000

Hi there,

I am running exchange 2000 on four different servers, we have 2 domains
and three of these servers are in 1 domain and one other server is sitting
on its own domain.

THe routing group status on the server in HQ is set to unreachable for all
groups. One more thing, emails between the HQ & 1 branch isn’t flowing
out, whereas everything else is working.Email sits on the queue
(Destination Unreachable” but once I restart the SMTP service on the
Exchange server in HQ, email starts flowing out and then stops again after
15 minutes…

Please assist…

Exchange Server 2003 next step in setup.

DigitalCreature — Wed, 13 Jul 2005 05:00:07 +0000

We have a Windows Server 2003 running Exchange Server 2003, I’ve just installed Exchange 2003 and curious if we will need to register for domain name? We only need the e-mail to work for the in house mailing within our own network.
