Network - Hardware related question

Suppose that I have two applications on my desktop, with different network needs, one requiring a dedicated line and another requiring just the regular network as the internet traffic. Physically, how can this be set up? What components would I require (switch, router, etc)? Any pointers please?

thanks
Sridhar

Hi Sridhar,
Please take a look at the JavaRanch Displayed Name Policy. We require the displayed name to be a real name. Could you please remove the "001" from the end of your name? You can change your displayed name here.
I don't believe this question has anything to do with getting the Sun Certified Enterprise Architect. I have moved it to the General Computing forum.
Can you please explain what you mean by "you have two applications on your desktop"? Do you mean you have two applications on your single PC? In which case, why do you need a router?
Assuming you mean you have two PCs you wish to connect to the internet, then there are several ways you can go about it:
  • If one of the PCs is running an operating system which supports routing of internet traffic (Linux, Microsoft Windows 2000/XP/(98?)) then you can connect that PC up to the network, and then:
  • Connect the other PC up via a network loopback cable.
    Advantage: really cheap. No extra hardware to purchase, no extra boxes using power.
    Disadvantage: harder to expand in the future.
  • Connect both PCs to a hub
    Advantage: relatively low cost. Last time I looked (a couple of years ago) you could get a cheap 8 port hub for about $30 US.
    Disadvantage: hubs are not intelligent - any traffic sent to one PC is actually sent to all PCs on the hub, and all the other PCs must reject the traffic. Additionally your hub will operate at the slowest speed any of your PCs can operate on - so if you have 3 PCs capable of 100Mb/s and 1 only capable of 10Mb/s then your entire network will be limited to 10Mb/s.
  • Connect both PCs to a switch
    Advantage: switches intelligent - the hub routes traffic intelligently (where possible) so any traffic sent to one PC is only sent to the PC it is intended. Can usually handle differences in speed - so if you have 3 PCs capable of 100Mb/s and 1 only capable of 10Mb/s then your network traffic will work at 100Mb/s per second between the PCs which are capable of it.
    Disadvantage: relatively more expensive. Last time I looked (a couple of years ago) you could get a cheap 8 port switch for about $50 US.

  • If your PCs aren't capable of this, then you can normally purchase modems which can connect directly to the internal network, in which case you could connect them to the hub or switch. Some even have a hub or switch built in. Most have routers and firewalls built in.
    Regards, Andrew

    Actually this question is related to the exam. It popped up because I misread a certain requirement. I took that the travel agents have two connections. 1. A dedicated line to access Transmaster 2. A regular network for accessing Frequent Flyer system.
    I realized that the dedicated line is used by FBN agency to connect to Transmaster and not by the travel agent.
    But still, I find the question is worth exploring and have posted my comments below.
    >>>Can you please explain what you mean by "you have two applications on your desktop"? Do you mean you have two applications on your single PC? In which case, why do you need a router?
    Application 1. Browser - Requires only regular network lines
    Application 2. Thick Java client - Requires a dedicated line to connect to a certain server site
    Both the apps are running on the same physical computer.
