HLA Time Management Mechanism

In HLA, the logical time management policies of Federated members are divided into two types: time regulating and time constrained)

1. both time control and time restriction are also called logical time synchronization. federated members affect both other federated members and the other two groups of Members. For example, one simulation has two members, if both Members are time-controlled and time-limited, their time push will affect each other. If any member wants to push forward, other members will apply for advance (but the progress is not successful ), otherwise, if the Promotion Department succeeds, the natural simulation process cannot proceed, and Members cannot receive data they are interested in from other members,

2. Neither time control nor time restriction, also known as external time synchronization. Members of this time strategy can push forward as much as they want, and its promotion will not be affected by any other Members.

3. only time is limited, that is, logical time is passive. Time is pushed to receive the influence of other Members without being impressed by other members. That is to say, if other members in the Federation do not push at this time, they do not want to push forward, it can be promoted only when other members move forward.Note: If the federal execution does not have a time control member (except for a given member), the minimum timestamp of the member is infinite.

4. Only members with time control, also known as logical time taking the initiative, time promotion affects other members, not other federated members.

 Note: Members with time constraints can accept messages only in the time advancing status, unless asynchronous message transmission is enabled (by calling the _ rtiambassador. enableasynchronousdelivery () Service ). If asynchronous message transmission is enabled, a time constraint member can accept Ro messages when they are not in the time push status. However, TSO messages can only be received when the time push status is enabled.
