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.

Creation of VLAN

Divanshu — Thu, 28 Jul 2005 03:19:35 +0000

How can I set up four VLANs on L3 (cisco 4507R 32 Ports) with Central Router and Database Server access provided for all VLANs, but maintain security between them (i.e. so nobody from the first VLAN can gain access to the second VLAN and vice versa but can access VLAN 4 which has Central Router and Database Server)

Content Load Balancing Switches

Bobkberg — Wed, 27 Jul 2005 15:58:34 +0000

Hi all – I’m working on a network design for a colo-based service site which will be load balancing both http and MySql (authenticated) services, and I’m looking at two possible solutions.

1) One of the Nortel Alteon content switches (low end)

2) The Cisco CSS-11052 content switch.

I’m somewhat familiar with the Alteon’s (having worked on them in the past).

Does anyone have experience with either – or better – both?

The main reason for considering the cisco at all is because it simplifies my purchasing picture – but it may also be workable for what I’m doing.

Opinions please?

Thanks,

Bob
