What is bandwidth?
Bandwidth is a term used to describe how fast data can potentially transfer.
What is MTU's off-campus bandwidth?
The total off-campus bandwidth is 155Mbps with approximately
half the available bandwidth being committed to Resnet.
What is MTU's internal bandwidth?
Bandwidth varies by location and uplink. All critical links are monitored and have ample capacity to handle our network load.
What does upload/download mean?
Upload is the process of sending data to some other device, Download is the process of receiving data from some other device.
Why is Michigan Tech restricting bandwidth?
Michigan Tech has filters to control how much data can flow so everyone can have their fair share of the total bandwidth. Some bandwidth intensive or problem protocols have tighter controls than standard services.
How come some sites are slower than others?
Each device on the Internet has many limiting factors that could affect their connection to another device. Among common problems are: oversubscribed connections, sub-optimal routing, interconnection agreements between backbones, and load on all elements between sites.
What is being measured/monitored?
All core network devices have data collection active for TC use. Many edge devices are monitored, and some public information is published for all to view. However, much is restricted to the Telecom office and related departments and used to manage the network. Public and system information will be published Here.
Is Michigan Tech invading my computer to find information?
Michigan Tech does monitor the network. Any traffic passing over the network is able to be monitored for specific items, such as potential virus and hack attempts. Any information passing over the Internet can also be monitored by any service provider the traffic crosses, or at Carnivor or other taps. The network is attached to the public networks and should not be considered private. Michigan Tech does not 'invade' computers, but may run port scans and take other reasonable measures to ensure network integrity and protection of campus resources.
Can I use a routering device to share
my IP address with others?
You may ONLY use a router
to share your connection between your own computers and
NOT with others as per
Michigan
Tech's Computer Use Policy. By sharing service with
a friend or roommate, you are breaking Michigan
Tech's Computer Use Policy and subjecting yourself to
take full responsibility for the actions of the person(s)
you are sharing with.
Are private wireless networks permitted?
Resnet subscribers are NOT permitted to share their connection with others. A subscriber may use an access point as a bridge to access the campus network providing they are the only user, lock the MAC table to their machine, restrict power levels, and use freqencies assigned by Telecom to avoid interference. Wireless networks on campus are subject to monitoring for number of stations attached, traffic, frequency usage, and other relevent data.
Are wires on MTU's network secure?
NO
Can MTU shut off my service without warning?
If a condition occurs where a device is causing network problems, it will be removed until corrective action is taken. Any violation of policy or law may result in removal of services without warning.
Can I reduce the amount of bandwidth I use?
Turning off unwanted protocols, services, and programs will greatly increase performance. Peer-to-Peer networks consume a large amount of bandwidth that reduces performance. Web browsing and other services are improved by using filters and caps.
Can I probe, intercept, or monitor other users traffic?
Use of tools to monitor a network other than under your control is illegal. Anyone engaging in such activity is subject to prosecution.
Will the Resnet Consultants help me configure
my router?
No. There are too many router brands and models to help
each customer configure. You will have to know how your
router works. You will need to know the WAN MAC address of your router.
If you have a router with wireless, know
the security risks that come with wireless. Out of the box
almost all routers are insecure! Again, depending
on your router's vendor, you can enable WEP or WPA encryption,
disable SSID broadcast, and use MAC address filtering. These
three steps will help, but is not limited to, keeping your router secure. You must use an SSID that is not obscene and does not conflict with university sanctioned services. Spoofing the MTU network services is illegal and will be prosecuted! MTU requires that you run your wireless router at no more than 35 mW. This prevents adding additional noise into the spectrum. Also note any unlicensed devices such as cordless phones, Bluetooth phones, microwave ovens, other APs, video cameras, and may other unlicensed devices do cause interference issues. Due to the broad
spectrum of vendors, Resnet does not offer customer support
relating to routers. If you have questions about your router,
you will need to contact your vendor or the place where
you purchased your router for support.
Will there be bandwidth issues if I multihost? - If you use a switch NO.
- If you use a hub YES.
- If you use a router YES.
Each IP address starting with 141.219 is bandwidth shaped so each user (device) gets its path down the pipe. By multihosting on our network, each device you register will get its own 141.219.x.x IP address and therefore have its share of the total speed regardless of the total amount of users (devices) on the network. However, there are a few things to consider.A hub is rather dumb, whatever traffic enters one port gets passed out all the remaining ports regardless if a device on one of those ports requested the information. This in turn slows all of the devices (on the hub) down and reduces each of the devices' effective speed. It will do this even if each device has a 141.219.x.x IP address. A switch is smarter, when traffic comes in on one port, it will only be sent to the the port that requested it. Thus a switch can perform many bridges by switching which port data is sent to. This is also where the term switch comes from. A router used in NAT mode (which all store bought ones are) only uses one 141.219.x.x IP address and shares it among all devices connected to it. If you recall the above statement about bandwidth shaping, you can see your devices will only be allocated one path down the data pipe which they will have to share versus each device getting its own path down the data pipe. Since you are routing your traffic to a single MTU IP address, you are technically not multihosting with this method. Your best bet is to use a switch, however you may use a router to setup your own private wireless network. To find out more about the difference between a hub, switch and router click here.
