Tóm tắt
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 ofexistent 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
