RE: Traffic characteristics

[Raj Sharma <raj@xxxxxxxxxxxxxxxxxxxx>]

You could use self similar traffic patterns.

There is quite a bit of publication on such traffic

patterns. William Stallings had a book that spent an entire

section on it. (High performance networks ---- or something

like that)

 

However, isnt this more of a "regression" parameter

rather than "main" parameters we want to test our

Layer 2 protocol against. Much of the issue that

we need to sort out for these main parameters

are the ranges of value. Cooking up these values must

make practical sense and they cannot be pathological

cases to test boundary conditions.

 

Perhaps what we need to do is to move one level up

and ask ourselves what services will get provisioned

over (layer 2) RPR and hence what are the main parameters.

Remember you cant design a layer 2 protocol only

based on a specific layer 3 protocol. If that is the case, I rather

do MPLS switching over rings.

 

Thoughts?

RPR'ers,

 

I raised this question about 3 weeks ago and got the familiar underwhelming response!

 

Several people indicated availability of traffic patterns that were taken off the Internet or other networking environments that would be useful for us to use in the simulations. In my mind, we need things like packet size distributions, interarrival times, burstiness, application and protocol distributions, and any other relevant characteristics of network traffics that we may want to consider in the simulations. 

 

Does anyone have such information that they can share with us in the meeting next week?
