BUPT Generic connectionless network information models
Flow
An aggregation of one or more traffic units with an element of common routing.
--- ITU-T G.809
“connection” in connectionless network
Page 14 APNOMS 2007
BUPT Generic connectionless network information models
A flow has the following properties (ITU-T G.809) : it is a unidirectional entity;
a flow can contain another flow. This is recursive until, for example, the limit of a single traffic unit is reached;
flows can be multiplexed together in the same layer network;
flows can be multiplexed together as part of adaptation to a server layer network;
a flow can be associated with one or more topological entities;
a flow can be defined in terms of a parameter such as its characteristic information, the address to which traffic units are directed or the address the traffic units have come from;
the aggregation of traffic units may be spatial or temporal.

Flow “connection” in connectionless network
Flow
FlowPointPoolLink
represents the topological relationship and available capacity between a pair of flow domains, or a flow domain and an access group, or a pair of access groups.
ConnectionlessTrail
represents the transfer of monitored adapted characteristic information of the client layer network between connectionless trail termination points.
