Abstract: | Current communication networks consist of subnetworks of different types. Therefore a common network protocol has to be used
for the transmission of data in such a heterogeneous network. Since some time the requirement of mobility in communication
networks is showing up. For that reason wireless networks are playing an increasing role as subnetworks. On the other hand
there is the need for multiplexed transmission of time-critical and non time-critical (normal) data within a heterogeneous
network. In this paper we discuss the problem of multiplexed transmission of time-critical and of non time-critical data over
a wireless type subnetwork using a common standardized network protocol. Many of the available wireless subnetworks are of
low or medium transmission speed and guarantee a fixed transmission bandwidth at the access point. We describe a mechanism
to transmit time-critical data in such a type of subnetwork using a connectionless transport and a connectionless network
protocol. The concurrent transmission of non time-critical data using a connection oriented transport and the same connectionless
network protocol is assumed to be of lower priority; it is scheduled in a way to fill the remaining capacity, which has not
been reserved for the transmission of time-critical data. In our discussion we concentrate on the standardized ISO/OSI protocools
CLNP as connectionless network protocol, CLTP as connectionless transport protocol and TP4 as connection oriented transport
protocol. We propose a header compression protocol and a fragmentation protocol for use on low bandwidth subnetworks.
