スパニングツリーの新しい仕様が、2001年にIEEE 802.1w として公開されてから6年が経ち、最近発売されるLAN スイッチ製品ではRSTP をサポートしているのが当たり前になりました。
RSTP の一番のウリは、トポロジ収束の早さです。
従来のスパニングツリー(IEEE 802.1D)では、全てのLAN スイッチが特定のスイッチをルートブリッジと認識して、安定したツリートポロジに収束するまで、最短で30秒掛かりました(全てのスイッチポートが同時にリンクアップした場合)。
15秒(Forward Delay)の2倍。状況によっては、更に20秒掛かります(Max Age)。
RSTP では、トポロジの規模や構成にもよりますが、早ければ一瞬で、遅くともだいたい数秒で収束します。
何を根拠にポートをFORWARDING とするか
STP とRSTPの収束に要する時間の違いは、スイッチが何を以てループが存在しないと判断するか?に拠ります。
スパニングツリーの目的は、任意の物理トポロジ上に、ループの存在しない(ループフリー)論理トポロジを構成することです。
ポートの先にループが存在しないことが確認できて初めて、そのポートをFORWARDING にすることが出来ます。
RSTP では、ポートがリンクアップすると、対向スイッチにBPDU(Proposal)を送信します。
Proposal を受信したスイッチは、自分の全ポートでループが存在しないことを確認した後、BPDU(Agreement)を返信します。
Agreement を受信したスイッチは、晴れてそのポートをFORWARDING とすることが出来ます。
+--------+ Proposal +--------+ Proposal +--------+
| Switch | --(1)--> | Switch | --(2)--> | Switch |
| A | <-(4)--- | B | <-(3)--- | C |
+--------+ Agreement +--------+ Agreement +--------+
つまりRSTP では、ポートをFORWARDING にして良いかスイッチ間で交渉(Negotiation)しているわけです。
これに対してSTP は、ポートをFORWARDING にして良いか判断するために、Forward Delay(デフォルト = 15秒)というタイマーを使います。
Forward Delay の満了(Expire)によってポートステートが遷移して行き、LISTENING、LEARNING の間により強いBPDU を受信しなければ、そのポートはFORWARDING となります。
つまり、トポロジ上の全てのLAN スイッチポートが同じタイマ値(15秒)であることを前提とし、タイマ満了によってループが存在しないと判断しているわけです。
スパニングツリーのタイマ設定は、ルートブリッジに設定された値が全てのスイッチで使われるので、必ず全スイッチで同じになります。
この違いは、トポロジ収束の仕方に現れます。
STP は、中心に位置するルートブリッジから送られてくるBPDUに基づいて、トポロジの中心から辺縁(エッジ)に向かって収束していきます。
RSTP は、上流から受け取ったBPDU に基づくのはSTP と同じですが、下流のスイッチとの交渉が必要なので、トポロジの辺縁から中心に向かって収束していきます。
なぜSTP で交渉ベースのトポロジ収束が出来ないか?
対向スイッチにProposal を送信し、Agreement を受け取ったらポートをFORWARDING にする。この程度の簡単な処理がなぜSTP では出来ないのか?
理由は、3台以上の機器がリンク上に存在し得るシェアードメディアでの使用を前提としているからです。
STP の仕様が802.1D の一部としてIEEE に承認されたのは、1990年の5月です。
その頃主流のLAN メディアは、バス型の10BASE5 や10BASE2、リング型のToken Ring など、3台以上の機器が一つのリンクを共有するタイプでした。
Twisted Pair ケーブルを使う10BASE-T が802.3i として承認されたのが同年の9月。ペアケーブルでの全二重通信が802.3x として承認されるのは1997年3月です。
リンク上に3台以上の機器が存在すると、どうなるか?
2台の機器間で交渉してループフリーを確認しても、3台目の先にはまだループが存在するかもしれないのです。
そのような状態でポートをFORWARDING にすることは出来ません。
3台目とも交渉してループフリーを確認しても、4台目は?5台目は?6台目・・・際限がありません。
ループフリー ループ??
: :
| |
+---+----+ +---+----+
| Switch | | Switch |
| B | | C |
+---+----+ +---+----+
| |
*------+-----------+----------------+--------*
| 10BASE5
+---+----+ 10BASE2
| Switch | 10BASE-T(HUB)
| A |
+--------+
リンクに存在するスイッチの台数を知る手段が無いからです。
シェアードメディア上で交渉ベースのトポロジ収束を可能にするためには、リンク上のスイッチを事前に登録するか、OSPF のようにスイッチ間で隣接関係を構築する別な仕組みが必要です。
仮にシェアードメディア(10BASE5)上で交渉ベースのスイッチ間交渉を行うとすると、どうなるでしょうか?
Ethernet のセグメント上には、最大1024台の機器が存在できます(CSMA/CD の動作に基づく上限値)。
参考:Ethernet の再送処理 - バックオフアルゴリズム
1024台全てがスイッチだとすると、(1024*(1024-1))/2 で、523,776 通りの交渉が必要になります。
まず、1,023台のスイッチと交渉しなければなりません。これだけでも相当な手間です。
セグメント上の全ての組み合わせが交渉し終えない限りループが存在しないことが保証できないので、他のスイッチ間の交渉状況(522,753 通り)も常に監視する必要があります。
はっきり言って、タイマーを使った方が早くFORWARDING にできるし、スイッチの負荷も相当軽くなります。
RSTP がRapid Reconfiguration できる理由
ポートの先に1台しか存在しないことが分かっているからです。
ポートがFull Duplex に設定され、リンク上の機器が自分の他に1台だけという状況が保証されて初めて、交渉ベースのトポロジ収束が可能になります。
RSTP であっても、ポートが半二重で動作している限り3台目が存在する可能性があるので、タイマーによるトポロジ収束となります。
(スイッチによっては、半二重であっても強制的にRSTP を動作させるよう設定できるものもありますが、RSTP が正常に動作するのは、スイッチと直接接続されている場合のみです)

They promise that after two years窶兪time in case that hair grows back again, all the treatments will be free of cost.

The very simplest method to find laser light hair treatment in your neighborhood is certainly referral and not ever just by an MD who is receiving a piece of the pie. I used to visit an Doctor for laser light treatments. I had uneven hairy areas and had also been through all of those other hair removal treatments. I bought a silk'n hair removal and have never been happier. At last I will be hair free for the summer season months. This will be a fantastic yr for me.
