Re: [802.21] Transport protocol issue!

Title:

Subir:

If R1 is available, it means we have peers of MIHF that are able to exchange
MIH frames with each other OTA using the native L2.

Under such condition, L2 should be used between these two. Why would  L3
be considered for MIH frame exchange when R1 is available to be used. 

When R1 is not available, L3/L4 is the next logical case.

Why did we bother defining MIH frame at all for L2? Should we have defined
MIH packet instead?

Peretz,
Why do we want to do this way?   Does this mean if we have L2 we don't need L3 for all cases?

Kalyan,
Thanks for the clarification. I believe we should strive for transparency of the transport protocol, i.e. the MIHF does not know which one is used.

Hi Stefano,

with #2 I mean, whether the MIHF should know how the transport 
protocol is constructed.

If the answer is yes, then we have some sort of dependency. 
Example, a change in transport protocol (from its standard) 
needs a change in the MIHF, at the minimum from implementation 
point of view.

Kalyan

Kalyan,
Can you elaborate a bit more on #2?

Hi All,

while going through the present draft, couple of questions
arised where I would like to hear to the experts opinions.

Considering: Communication between 2 MIHF peers using MIHF protocol
            with an arbitrary transport protocol.

1. Should the MIHF know over which transport protocol messages are
  exchanged?

2. Should MIHF be in a position to dissect the transport protocol?
  (if yes, then do we have transport protocol dependency?)

3. Is PPP also a possible transport protocol for MIHF communication?

Kalyan
