Avoiding Collision

08/16/2014 7:18 AM

hi, if you have any recommendation for the future for decreasing number of collision and still transmitting large number of packets please feel free to comment down below. I need for my assignment thank you.

You've given no detail as to what bus architecture your using.

Are the collisions in a router? Are you exceeding buffer memory in a switch?

Is there a TCPIP type protocol?

So, without details, implement unidirectional bus, point to point.

so sorry, its a bus topology, collisions occurs in transmission link. Is it possible to exceed the buffer memory. Using CSMA/CD protocol

What is the physical layer of the bus? e.g. EIA RS485, CAN BUS etc. Since your referring to collisions, this must be a bi-directional bus. So the transmitter must be tri-state-able.

There are many collision protocols that have been invented.

From seeing your replies to Lyn, it appears you know nothing about any 7 layer OSI stack, starting with layer 1 the physical bus type.

Have you searched using "CSMA/CD protocol", this was used in the old days on early Ethernet, I consider this obsolete.

i'm sorry for not giving the details. I'm using bus topology and CSMA/CD protocol. i have an idea of using diff topology which can support more packets send and less collision occur'

i'm not cheating. i just need help for my idea. i have stated that my idea to change the topology and asked if anyone who are expert in this major to explain to me. i dont ask them to write my report. in the same time i dont want to write something out of sense in the topic. that is why i'm joining this site for seek help and expertise.

in fact i don't wait for this site to tell me what i should write. i write my report first if i think the answer making sense and its a great idea and something i should bring up to my report why not? everyone have their own creative mind to solve some question. Why not?

You can justify asking someone for the answer any way you want.

From your first post: "can anyone explained to me in detail how the collision occurs"

The point of assignments is to get you to explore the available technology and arrive at some possible conclusions, ON YOUR OWN.

"if you have any recommendation for the future for decreasing number of collision and still transmitting large number of packets please feel free to comment down below." sounds like you are asking for the answer.

Have you done any real research? If you have, why not propose your solution for the forum to see instead of asking for recommendations on how to do it.

Let's see if you've really done anything. Publish your conclusions.

Does any one explained in 2 or 3 pages? i just don't understand how it work? how can i write. most of them give me links to books and link to something new that got me hooked to read all of the links. Which is great. I've spent my night reading the links give. Which really contributing to my own understanding. and from my first post you make me confused. When i have been reading a lot it says it listen before transmit and you said they dont listen. Which really confusing. You should not confused people when they have shaky background. I'm just a telecommunication student and trying to exposed many things. trying open my mind and communicate with expertise. If you dont have any educational to share me. Dont bother to comment. really wasting my time.

L, You have many many answers but so many of them are couched in "hard-ass drill instructor" theory. That's not the only way people learn. Specifically, many educational theorists think that team learning and mutual discovery are also very efficient, as well as leaving the learning team with positive feelings for each other. I also don't think that insulting people by saying they're missing brain parts is even allowed here, if I read the forum rules correctly. How about both of you backing off? Guy's got an interesting question, but links and dismissive rudeness aren't teaching me anything. I don't come here for ego games.

" many educational theorists think that team learning and mutual discovery are also very efficient, as well as leaving the learning team with positive feelings for each other."

You must be an advocate of "Common Core" teaching.

People only learn dependency if given the answer without having to go through the mental process of understanding how the system works.

I stand firmly behind every word written in #7 and invite you, as I have before when you admonish me, to feel free to offer the OP any and all help you see fit.

that's impressive, you know how people learn dependency. No one is admonishing you Lyn, we love you! You are the guy with the lunch table all to himself. BTW, it's great izzyakm that you are interested in collisions. You are in the right place.

If you want no collisions go back about 20 years and use Token-Ring technology.

On Ethernet, the purpose (one of them) for making it so fast, is that collisions happen so quickly that it's as if they never happened at all.

Finally, go here: http://en.wikipedia.org/wiki/CSMACD

Re: avoiding collision

Don't even start with me... The reason why I chimed in was that there is so much damn information out there regarding the subject it's flippin' ridicules to be taking so much time on the subject.

The article on Wikipedia is straightforward and easy to understand. Even if it's a case of ESL or even pure translation (which Wikipedia provides) the info is very available. This kid was just being lazy. If not, that's when I call his brain into question. Now go lite up another dube, and let's drop the subject.

you mean her brain. as far as i'm concern i'm not lazy ass. i'm the only girl in my class taking engineering course. i'm the only one writing notes. i'm the only one distributing notes when my classmates(guys) when they want to do revision.

I'm sure you must be very popular in your class. Also, did you check out the Wikipedia article I suggested? Did it help?
