得られた知識
・UDPと基本的には同じ考えでOK。
最大スループットを超えた場合の動作は？
たとえば、こんな構成
Ubuntu1→3に最大スループットで通信中に、Ubuntu2→3への最大スループットの通信を開始したら、どうなる？
スイッチのバッファがあふれパケットロスが発生するのでは？
TCPの場合
①Ubuntu3でiperfサーバをポート5201で起動
②Ubuntu3でiperfサーバをポート15201で起動
③Ubuntu1からUbuntu3のポート5201に対し、TCPモードで4並列で通信開始
④Ubuntu2からUbuntu3のポート15201に対し、TCPモードで4並列で通信開始
※③、④実行時のオプションは以下
iperf3 -c 192.168.0.252 -M 1460 -t 180 -P 4 -p ポート番号
以下動作を確認
・③を実行後、④開始前まではポート5201に対し935Mb/sの通信が発生したことを確認
・④を実行後、ポート5201へのトラフィックは471Mb/sになり、ポート15201も471Mb/sになった。
・ポート5201、15201ともに再送は0
何回かやっても同じ結果。
TCPは応答確認が来ないと、次のパケットを送らないので、この動きになったのだろう。★誤り！後述★
UDPならパケロスがたくさん出るのでは？★誤り！後述★
UDPの場合
①Ubuntu3でiperfサーバをポート5201で起動
②Ubuntu3でiperfサーバをポート15201で起動

④Ubuntu2からUbuntu3のポート15201に対し、UDPモードで4並列で通信開始
iperf3 -c 192.168.0.252 -l 1472 -u -b 1000M -P 4 -t 60 -p 15201

・④を実行後、ポート5201へのトラフィックは479Mb/sになり、ポート15201も479Mb/sになった。
・ポート5201、15201ともにエラーは0
何故？？？？？と思い送信側のパケットキャプチャを見ると、、、、
第9回 イーサネット（その４） - フロー制御とVLAN、トラブルシューティング：詳説 TCP/IPプロトコル（1/5 ページ） - ＠IT
MAC制御プロトコルでフロー制御を行うためには「PAUSEコマンド」を使用する。PAUSEコマンドはMAC制御フレームの宛先アドレスに「01:80:C2:00:00:01」、操作コードに「0x0001」、制御コードに続く2オクテットに送信の「中断時間（0～65,535）」を指定したPAUSEフレームを使用する。PAUSEフレームを受け取ったステーションは、そのデータ・フィールドに指定されている「中断時間×512ビット時間」の間（512bitはフレームの最小サイズ）、送信を中断することでフロー制御を実現する。
スイッチング・ハブ側では、バッファの空き容量が残り少なくなったときにPAUSEフレームを送信する（そして空きが十分できたときに、中断時間を0にしたPAUSEフレームを送信する）。送信ステーション側では、指定された中断時間の間だけ、もしくは中断時間が0と指定されるまで、送信を中断する。
Ethernet の flow control(フロー制御)の概要と設定 〜IEEE802.3X PAUSE〜 | SEの道標
スイッチはインタフェース単位で輻輳を検知し、受信リングバッファ (rx-ring) がオーバーフローする前に、そのインタフェースからマルチキャスト (0180:c200:0001) 宛に PAUSE フレームを送り、受信した端末は一定時間通信を止めます。
cisco では IEEE802.3X はデフォルトで無効になっています。
L2レベルでも、フロー制御の機能があった。。。。
PAUSEフレームなるものがあり、中断時間65535で通知し、バッファに空きが出たら、中断時間0を通知していた。
もしかしたらTCPの時も、こうだったのか？？？と思い確認してみたら、ビンゴだった。
後からトラフィック送信した方が、データを送り始めたタイミングで、最初にトラフィック送信していた方で、PAUSEフレームを受信し始めた。
Ubuntu1,2で、このフレームを受信し、Unbut3では受信しない動き。
スイッチは、NETGEARのGS108Ev3使ってたが、古いファーム(2.0.0)だとデフォルトで有効だったもよう。
2.06.17にすると、有効/無効を設定できる。ただ、2.06.17だとデフォルト無効っぽかった。ファームアップしたら、無効になってた。
https://www.downloads.netgear.com/files/GDC/GS105EV2/WebManagedSwitches_UM_JP.pdf
フロー制御は、ポートがオーバーサブスクライブ (ポートが処理可能な量よりも多くの
トラフィックを受信) した場合にポートを一時停止し、輻輳状態中に瞬間的にすべての
トラフィックをドロップすることで機能します。 IEEE 802.3xフロー制御を有効または
無効にできます。 フロー制御はデフォルトでは無効になっています。
※ファームアップに2時間近くかかってしまった。。。。泣いてしまいそう。コスタリカに日本負けるし。
Firewall無効化 & DHCPにはしない方が良い。設定は、2.06.17はWebGUIでできる。
スイッチで802.3Xを無効にしてTCPで再度試す！
上述の通り、①～④まで実施。時間は60秒で。
以下動作を確認
・③を実行後、④開始前まではポート5201に対し935Mb/sの通信が発生したことを確認
・④を実行後、ポート5201、15201へのトラフィックは、どもに300Mb/後半から500Mb/s代をいったりきたり。明らかに、802.3X有効時比べ、不安定な動きとなった。
・ポート5201、15201ともに大量の再送が検知された。
