6. Protocol Data Unit: 電気通信において、protocol data unit（PDU、プロトコルデータユニット）とは、コンピュータネットワークのピアエンティティ（両端）の間で送受信される最小の情報の単位である。 PDUは、通信プロトコルで定義された制御情報（ヘッダ）部分と、通信データの中身であるペイロードからなる。 通信プロトコルスタックの階層化アーキテクチャでは、各層は、特定のタイプやモードのデータ交換に合わせて調整されたプロトコルを実装し、それによって、プロトコルで規定されるPDUが異なる。例えば、TCPはコネクション型転送モードを実施し、このプロトコルにおけるPDUはセグメントと呼ばれる。一方、UDPはコネクションレス型転送モードを実施し、PDUとしてデータグラムを使用する。インターネット・プロトコル・スイー.
