- REP
CISCO独自プロトコル。マスタースイッチを指定しない。
それぞれのスイッチがやりとりをする。プライマリーポートもない。
障害発生時には、障害ポートを持つスイッチが全スイッチに通知を行う。
ブロックポートはどこにでも設定可。障害からの復旧時も、
ブロックポートをオープンにしたままでよい。
- 普通のリングプロトコル
マスタースイッチを一つ決める。
そのマスタースイッチのプライマリーポートからHelloメッセージを
定期的に送信することで、正常稼動を確認する。

JacORBのつづき
javaはC:\j2sdk1.4.2_19\bin\javaに配置しています。
- jaco.bat

- ns.bat(Naming Service)
@echo off rem Starts the JacORB name server jaco org.jacorb.naming.NameServer %*
- ntfy.bat(Notification Service)

さらに、naming serviceに登録されているオブジェクトを見ることができるっぽい。
- nmg.bat(the JacORB name manager)
@echo off rem Starts the JacORB name manager jaco org.jacorb.naming.namemanager.NameManager %*
んで、idlのクラス生成用
- idl.bat
@echo off C:\j2sdk1.4.2_19\bin\java -classpath "%JACORB_HOME%\lib\idl.jar;%JACORB_HOME%\lib\logkit-1.2.jar;%CLASSPATH%" org.jacorb.idl.parser %*
