Broadband Automatic Port Management System's Design And Implementation Based On Java

Developping　rapidly　with　Internet,　network　attracts　people　with　abundant　network　resource.　People's　life　can　not　do　without　the　network　any　more,　such　as　amusement　of　the　network,　network　recreation,　shopping　at　network,　etc.　These　result　in　broadband　users　to　increase　rapidly.　Managing　port　of　DSLAM　by　hand　can't　already　satisfy　demands.　In　order　to　enhance　quality　of　service,　attract　more　customers　and　standardize　users'　behavior　that　they　use　broadband　network,　ISP　(Internet　service　provider)　must　manage　port　of　DSLAM　rapidly　and　correctly.　All　those　means　that　a　good　Automatic　Port　Management　System(APMS)　is　absolutely　necessary.　Automatic　Port　Management　System　is　important　to　QoS　of　network,　user's　benefit　and　profit　of　ISP.　In　this　acticle,　the　principle,　the　design,　the　implenentation　and　the　key　technology　are　researched　in　detail.　The　following　contents　are　primary.　1)Introduced　broadband　network,network　actuality,network　access　mode　and　port　of　DSLAM　management　techology.　2)Introduced　SNMP　protocol　and　application　of　Management　information　base　in　port　management　system.　3)Introduced　principle　of　managing　port　of　DSLAM;　4)Analysed　demands　of　Automatic　Port　Management　System;　5)Designed　the　technology　scheme,　the　whole　frame,　functions　and　databse　construction　of　Automatic　Port　Management　System;　6)Researched　solution　of　key　functions　and　techolgy.　This　paper　presents　a　collection　of　solutions:　used　Java　muti-thread　for　enchanced　performance,　used　JDBC　for　improving　access　database　speed,　used　adapter　to　communicat　with　DSLAM.　The　experiment　proved　that　these　schemes　receive　the　good　result　and　can　turn　on/off　user's　port　fast　and　accurately.　Meanwhile,　system　supports　many　ways　of　managing　port.
