　具體技術(shù)要求

　基本要求:
*）可管理*萬用戶規(guī)模，支持*并發(fā)，將來可以通過lisence平滑升級;
*）*萬或以上用戶環(huán)境下，要求系統(tǒng)鏡像數(shù)據(jù)流和文件分發(fā)數(shù)據(jù)流分別采用獨立服務(wù)器部署，且互為備份，加強穩(wěn)定性。;
*）要求系統(tǒng)采用純軟件分布式部署，方便今后服務(wù)器配置根據(jù)發(fā)展需要靈活增加內(nèi)存和硬盤等**，保護現(xiàn)有投資。;
*）投標(biāo)產(chǎn)品具備廣電級的大規(guī)模的應(yīng)用環(huán)境，提供*個或以上廣電級別規(guī)模應(yīng)用案例和合同證明文件，保證系統(tǒng)的穩(wěn)定性。;
*）要求系統(tǒng)可根據(jù)不同的硬件載體自動生成唯一的授權(quán)碼。;
*）軟件系統(tǒng)支持雙機負載均衡模式，將來用戶大的時候可平滑升級;
*）要求緩存軟件要使用穩(wěn)定的linux操作系統(tǒng);
*）整個緩存系統(tǒng)可管理存儲容量最少**T;
*）整個緩存系統(tǒng)必須旁路在核心網(wǎng)絡(luò)，而且不能影響核心網(wǎng)絡(luò)正常應(yīng)用;
**）吞吐量大于*GB每秒。
視頻加速功能:
*)緩存系統(tǒng)需具備自動緩存WEB視頻**的功能，能夠儲備大量視頻**為用戶供速;
*)當(dāng)用戶進行web視頻觀看時，只有緩存系統(tǒng)中沒有**時才會通過互聯(lián)網(wǎng)去訪問,如果緩存系統(tǒng)有**，則通過緩存系統(tǒng)對用戶進行數(shù)據(jù)供給;
*)支持優(yōu)酷、搜狐、新浪、酷六、土豆、奇藝等主流視頻網(wǎng)站;
*)可以指定緩存部分網(wǎng)站視頻，或全部視頻;
文件加速功能:
*)緩存系統(tǒng)具備自動緩存Http文件**功能，能夠儲備大量文件**為用戶供速;
*)能夠按照文件大小區(qū)間進行自動緩存;
*)根據(jù)指定的文件類型進行緩存;
*)文件按照文件類型以及文件的最小大小進行緩存，文件的最小大小可以自由設(shè)定;
*）支持的文件類型至少有以下類型：
"exe","rar","zip","iso","ipsw","bin","ipa","dmg","pxl","app","deb","apk","*a","sis","sisx","jad","pkg","mpkg","elf","prc","nes","cab","cad","enc","img","dao","cif","fcd","gz","tarz","bz*","rmvb","avi","mp*","wma","wmv","txt","jar","umd","xlk","xld","xlc","xlb","xla","xls","*g*","*gp","*gp*","*gpp","aac","ac*","acc","act","aif","aifc","aiff","amr","amv","ape","asf","au","bat","bik","cda","chm","csf","d*v","dat","divx","doc","docx","drc","dsa","dss","dts","evo","flac","flc","fli","flic","fliv","m*a","m*v","m*a","m*p","m*ts","m*v","m*a","m*b","m*p","m*v","mac","mdf","mid","midi","mka","mkv","mod","mov","mp*","mp*v","mp*","mpa","mpe","mpeg","mpg","mpga","mpv*","mts","ogm","pdf","pmp","pmp*","ppt","pss","pva","qt","ra","ram","ratdvd","realpix","msi","rm","rmi","roq","rp","rpm","rt","rtf","scm","smi","smil","smk","snd","tar","tp","tpr","ts","tta","wav","wm","wmp","wps","wru","wv"
功能要求:
*)**供速時須與外網(wǎng)**原狀態(tài)進行核對。若外網(wǎng)**已經(jīng)下線、更改，則緩存內(nèi)**亦不得供速;
*)可以通過指定**請求次數(shù)的方式，進行**是否緩存的判定;
*)單臺服務(wù)器可以同時提供視頻、文件加速服務(wù);
*)當(dāng)用戶數(shù)增多時，可以通過添加服務(wù)器的方式來滿足用戶的增長需求;
*)當(dāng)磁盤文件滿時，需要對原有**進行刪除，系統(tǒng)可采用最長時間、請求人數(shù)最少的原則進行刪除;
*)緩存分析系統(tǒng)可檢查用戶請求**的源地址**狀況，當(dāng)源**發(fā)生改變、刪除時，可停止本地緩存**的供給，并刪除緩存的**;
配置管理:
*)能夠按照點擊熱度進行**的自動緩存;
*)能夠在指定時間段進行**下載;
*)能夠設(shè)定需要使用緩存的客戶IP地址段;
*)能夠屏蔽網(wǎng)內(nèi)已有的**服務(wù)器;
*)要便于維護和便于故障處理，可遠程處理故障;
性能統(tǒng)計:
*)能夠查看CPU使用率、內(nèi)存使用率;
*)能夠查看硬盤空間狀態(tài);
*)能夠查看所有的緩存文件，已經(jīng)緩存文件的命中次數(shù);
*)實時查詢各緩存服務(wù)器流入流出速率，*分鐘統(tǒng)計一次，可以查詢每一天的流量圖;
