ON EVALUATION OF DIFFERENT SERVICES ON MAN-E NETWORK BY BAC NINH DIVISION: A CASE STUDY

Abstract

The  paper  with  the  above  entitled  consists  of  two  main  parts,  A  and  B.  In  the  later  part, some  aspects  with  respect  to  shortcoming  of  wide  area  network  (MAN)  by  MAN-E  will  be reported  in the coming paper. In the "NGN of Vietnamese Posts and Telecommunication" (NGN of  VNPT),  different   results  are  reported  w.r.t  developing  NGN  of  VNPT.  On  the  basis  of
existent  telecommunication  network  of  VNPT,  the  NGN  are  developed  by  making  suitable change  from  the  classically  electronic  switch  with  Time  Division  Multiplexer  (TDM)  to  the Internet Protocol  Packed  Electronic Switch (MPLS/IP) in two steps. In  the  first  paragraph  of  this  paper,  different   principles  and  criteria  are  reported  for developing  NGN  w.r.t  conditions  of  VNPT  so  that  (i).  Existed  network  and  next  one  are simultaneously  working together and (ii). The next generation  one is opened  for further  carrying
out  different  developments.  All  these  require  different  stepwise  changing  from  basically  TDM to MPLS/IP for readily moving from  MAN to MAN-E.
Second  part of the paper  is for different  proposals in details with  respect to the second  step of developing the NGN of VNPT. The last one is for conclusions and directions for next paper
