Network Switch

Jesus † Freak asked:


I have my Xbox 360 in my basement and my computer and modem upstairs so I cant hook the cord directly to my modem like I need to to connect to xbox live so I am looking into getting wireless roadrunner but on the website it says it doesn’t support online gaming so I was wondering if that means I can’t get xbox live. If you know if there is anything I can do without switching networks please let me know. Thanks.

I’ve been going over Kleinberg-Tardos to prepare for a class, and come across this problem (any ideas):

Let’s call a floor plan — together with n light fixture locations and n switch locations — “ergonomic” if it’s possible to wire one switch to each fixture so that every fixture is visible from the switch that controls it. A floor plan will be represented by a set of m horizontal or vertical line segments in the plane (the walls), where the ith wall has endpoints (xi,yi), (xi’, yi’). Each of the n switches and each of the n fixtures is given by its coordinates in the plane. A fixture is visible from a switch if the line segment joining them does not cross any of the walls.

Give an algorithm to decide if a given floor plan, in the above representation, is ergonomic. The running time should be polynomial in m and n. You may assume that you have a subroutine with O(1) running time that takes two line segments as input and decides whether or not they cross in the plane.

Mizzle M asked:


I am adding a computer to an existing network via a “D-Link switch”. Do I need an adapter to connect the switch from one computer to another? I have T1 Ethernet. Serial ports not usb, also will the server recognize the new computer on the network? Will I have to do anything on the server to accept the new computer?

Mock scenario..
I have a DMZ on the perimeter of my internal network for security. It contains a VPN server, and an Email server. There is a firewall either side of these servers to control access into and out of the DMZ.

Can i use a switch to connect these servers together, and the firewalls or do i need a router? thanks
