UGN Security Forums UGN Security: Knowledge Base Programming Web Design, Protocols & Other Languages What is a Protocol

I think this should help keep prot alive. What is a protocol?

An agreement. A protocol is an agreement on how something should be run. Everyone agress that TCP/IP will act in a certain manor so that everyone can program everything to work together.

hmmm... kinda,

A protocol is a set of rules for a specific pourpose. They decide how the data packet will be broke up and what each 1 and 0 is there for. Some protocols are simplY in place to assist other protocols.

Usaly a protocol decide how a header and or trailer of a packet will be set up. The center (payload) is the data you want(MOST OF THE TIME). ATM for example is broke down into octets. an octet is 53 bits or bytes I forget now. Anyway the Payload is all the back end. All the over head is in the header.

They are also a set of rules that state how that packet is to be handled and by what, and on what level of the OSI modle they will be handled.

Check it out...

Follow that link, fill out the form with your real address. They will send you a huge poster of the main networking protocols...

Apple Talk
TCP/IP
Sun NFS Protocol suit
IBM protocol suit
ATM
ISDN
X.25
ect ect ect....

It is awsome. It is a map of all these protocol suits broken down across the OSI modle so you can see what gets done where.

That site also has posters for free on Cellular protocols

Anatomy of a PCS signal
Anatomy of a GSM and GPRS signal

Telecom networking communications
Anatomy of IN/AIN signal

It was a truley good find for me. They do send the posters our It took about 2 weeks.

It will give you pleanty to read up on on

Here have some links

This is a *.pdf of the poster I told you about for networking protocols...

Just to bak Learner up here, I received those posters earlier this week, and they are the [censored]. i live in Canada and it took about 4 weeks. If you are into this kind of thing then get these posters! After all, they are free.

sum

Here are a few sites that deal in protocols.

One of these days I will do up one long [censored] tut on some WAN protocols. That is an area I shine in.

I found this article that explains OSPF really well a while back, and have used it to avoid having to explain some basics to new hires for a while ;.)

To Rip or to OSPF

pretty good info le4rner, nice work.

now shall we also start discussin about standardisation here ? ISO [censored] and stuff like that which do have to deal with protocols.

Hey Le4rner. Thanks for the heads up on that poster. Looks cool. Free is good. I'm putting in for one now.
Thanks again.

Those posters cover many different protocol stacks and thier relation to the OSI modle. If you have a idea about the OSI mode and TCP/IP before you get it you can learn a ton from them. I wrote a couple tuts on the OSI modle and TCP/IP a while back.

http://rrfn.promodtecnologies.com/K-base/TCP-IP-OSI-Modle.html

first one is kinda the basics of the OSI modle, second starts to break TCP/IP's protocol stack up acorrding to the OSI modle. Pretty basic stuff, but if you are completly new it helps. If the posters look like russian, then these tuts will help out a bit.

I know a little about protocols as I deal with lower level protocols everyday. Basicaly layer 1, 2, and half way up layer 3, for the OSI modle.

Little not guys, TCP/IP is just one of MANY protocol stacks out there.

yes learner i agre with you...

i learned about the OSI model and TCP/IP shits long time ago.. there was times i was bored with em but usually it's funn, coz as you said there are tons of stuff to learn there if you want.

I like the layers thing, it helped me a lot to undestand how the whole things go especially data flow and so on, these are very very interesting things and i never get bored reading em.

heh i deal with all 7.

see ya guys, gotta [censored] up another cisco switch today lol.

Protocol

A set of formal rules describing how to transmit data, especially across a network. Low level protocols define the electrical and physical standards to be observed, bit- and
byte-ordering and the transmission and error detection and correction of the bit stream. High level protocols deal with the data formatting, including the syntax of messages, the terminal to computer dialogue, character sets, sequencing of
messages etc.

=====Many protocols are defined by RFCs or by OSI.=====

gosh dang, please mommy make them stop
