Can you advise me in detail why link error can cause cell lose? is that because of the ATM header HEC failure due to link error? If a sublayer is put below ATM to handle link error on links other than SONET/SDH, this kind of cell lose can be avoided. Yi Wang University of New Brunswick E-mail: yi.wang@unb.ca |
