sessionOptions.datagramDropPolicy

• 类型：<string>
• 默认: 'drop-oldest'

控制在待处理数据报队列（大小由 session.maxPendingDatagrams 决定）已满时丢弃哪个数据报。必须是 'drop-oldest'（丢弃最旧的已排队数据报以腾出空间）或 'drop-newest'（拒绝接收的数据报）。丢弃的数据报将通过 ondatagramstatus 回调报告为丢失。

🌐 Controls which datagram to drop when the pending datagram queue (sized by session.maxPendingDatagrams) is full. Must be one of 'drop-oldest' (discard the oldest queued datagram to make room) or 'drop-newest' (reject the incoming datagram). Dropped datagrams are reported as lost via the ondatagramstatus callback.

此选项在会话创建后不可更改。

🌐 This option is immutable after session creation.
