You are correct up til you get to the efficiency at the AAL level. AAL-5 does not have any SAR overhead but it does have 8 bytes of CS overhead. Now, this overhead is on a per PDU basis and NOT a per cell basis. Thus, you maximum efficiency will be
36.864 * [(x-8) / x] where x = PDU size in bytes.
Thus, if you just send 64-byte packets, your min throughput will be 36.8 * (56 / 64) = 32.3 Mbps.
Of course, larger PDUs are more efficient.
Thanks for the correction. I knew that number didn't quite look right. -dorian ______________________________________________________________________________ Dorian Kim Email: dorian@cic.net 2901 Hubbard Drive Network Engineer Phone: (313)998-6976 Ann Arbor MI 48105 CICNet Network Systems Fax: (313)998-6105 http://www.cic.net/~dorian
