>From what I remember - SNAP and VC-Mux are two differnet encapsulations for
layer 3 protocols over ATM. I think VC-mux only allows one protocol/vc
while SNAP (because of the additional header) allows multiple layer 3
protocols/vc of course at an additional cost of the SNAP header which I
would assume makes it too large for one ATM cell (48 bytes payload). This
is a rough approximation of what I remember from a class about a year ago.

| Hi Group,
|
| Could you please light me up on the following comments:
|
| "OSPF allows use of ATM VCmux encapsulation (so TCP acks fit in one ATM
| cell);
| IS-IS requires ATM SNAP encapsulation, forcing two-cell TCP acks (but Henk
| Smit's NLPID hack fixes this)."
| I have no clue what this means, please help here.
|
| Thanks
|
| Jack
