Abstract

Hybrid Multiplexing is categorized as the multiplexing method similar to the Time Division Multiplexer (TMD) or Packet Multiplexer. It means the sharing bandwidth of the trunk line of the multiplexer between Synchronous Transfer Mode (STM) connections, chiefly represented as voice connections and packet data connections characterized by its burstiness. Dynamic Partitioning is the implementation method to realize Hybrid Multiplexing. It slices the trunk line in every time constant. The time slot allocation, either to voice or to data, occurs in all sliced intervals according to voice connection demand.

Dynamic Partitioning for Hybrid Multiplexer

      Hybrid Multiplexing is categorized as the multiplexing method
similar to the Time Division Multiplexer (TMD) or Packet Multiplexer.
It means the sharing bandwidth of the trunk line of the multiplexer
between Synchronous Transfer Mode (STM) connections, chiefly
represented as voice connections and packet data connections
characterized by its burstiness.  Dynamic Partitioning is the
implementation method to realize Hybrid Multiplexing.  It slices the
trunk line in every time constant.  The time slot allocation, either
to voice or to data, occurs  in all sliced intervals according to
voice connection demand.

      Fig. 1 shows the multi-frame structure configured over the
physical leased-line structure.  The time slicing of the trunk line
is realized from it.  TMD defines the sliced duration.  Each time
slot in the frame is assigned to either voice connection or packet
data connection.  Identification of time slot usage is placed
anywhere in each  frame.

      As shown in Fig. 2, the time slots allocated to data connection
are logically aggregated as the data channels which bandwidth is
fluctuated.  It means that from the voice connection aspect, the
spare time slots can be allocated to the data channel and it
eliminates the loss of bandwidth, i.e., it emanates the opportunity
to allocate the spare bandwidth to the bursty data.
