Stop/Freeze PDU

Size: 320
Description: The stopping of freezing of an entity/exercise shall be communicated using a Stop/Freeze PDU. The Stop/Freeze PDU shall contain the following fields:

a) Simulation Management PDU Header - These fields shall identify the PDU header information, the originating entity, and the intended receiving entity. The Simulation Management PDU Header shall be represented by the Simulation Management PDU Header Record described in 5.3.29.
b) Real-World Time - This field shall specify the real-world time (UTC) at which the entity is to stop/freeze in the exercise. This field shall be represented by a Clock Time Record (see 5.3.8).
c) Reason - This field shall specify the reason that an entity or exercise was stopped/frozen . This field shall be represented by an 8-bit enumeration (see Section 7 in EBV-DOC).
d) Frozen Behavior - This field shall specify the internal behavior of the simulation and its appearance while frozen to the other participants of the exercise. This field shall be represented by an 8-bit enumeration (see Section 7 in EBV-DOC).
e) Request ID - This field shall identify the specific and unique stop/freeze request being made by the simulation manager. This field shall be represented by a 32-bit unsigned integer.

The Stop/Freeze PDU is represented in Table 45.
