Cisco WebexプラットフォームでリアルタイムVoIPアプリケーションを開発しているときに、ユーザーから、音声が途切れる、または会話の一部が途切れるという報告があります。どのネットワーク制約がアプリケーションに影響を与えていますか?
正解:B
Jitter refers to the variation in packet arrival times, which can cause packets to arrive out of order, leading to choppy audio or dropped parts of a conversation in real-time VoIP applications. Latency and delay refer to the time it takes for a packet to travel from source to destination, and capacity refers to the bandwidth available, but jitter specifically affects the consistency of packet delivery timing, which is critical for VoIP quality.
