2.3ADDRESSING MODES
Addressing modes refer to addressing of the logical entities called SAPs (Service Access Points) created
and maintained by the ControLink software. The concept of SAPs is illustrated by the Figure 4.
ControLink implements the ANSI/IEEE 802.2 Standard that defines these addressing modes. A SAP is a
logical entity within one physical station. Other stations can send a packet to this physical station and this
packet will be redirected internally to the SAP for which it is intended.
Thus ControLink offers four addressing modes:
