Multicasting minimizes the work bandwidth used. If clients do not use the station to receive the ASF stream, then each client requires its own connection to a server. This quickly consumes work bandwidth and limits the ability of the work to deliver information. Distribution mode is a station characteristic that defines whether a station is to be used for multicasting, distribution, or both. ? Multicast stations deliver ASF streams to many clients but use only the bandwidth of a single stream. ? Distribution stations deliver ASF streams to other Windows Media servers via unicast. A station that is solely a distribution station does not have an IP address or port, so clients cannot view the stream that the station delivers. ? Stations enabled for multicast and distribution deliver ASF streams to other Windows Media servers via unicast. Clients can also view the ASF content on this station via multicast. A station contains all the information needed to deliver an ASF stream to Windows Media Player, including IP address, port, stream format, timetolive (TTL) value, and so on. This information is stored in an .nsc file. Windows Media Player must be able to access the .nsc file so that it can locate the IP address that the station is using to stream ASF content. The .nsc file is typically made available to Windows Media Player from a shared work directory or from a Web server directory. Windows Media Player extracts the URL to the .nsc file when it opens an announcement that is delivered to it in an message, via UNC path, or from a Web page link. The Multicast Stations page in Windows Media Administrator is the access point for creating and managing stations. This page also provides an interface for anizing streams into the programs delivered on the stations you create. Understanding distribution stations A distribution station is a helper station. It delivers an ASF stream from Windows Media server A to a station on Windows Media server B so that Windows Media server B can multicast that ASF content. A distribution station provides a way to: ? Distribute a stream between work segments that are not connected by multicastenabled routers. ? Distribute a stream past a firewall. Other stations access the distribution station by creating a connection to the distribution station .nsc file using the MSBD protocol. For example, if you want Station2 on ServerB to multicast the ASF content from distribution station, Station1 on ServerA, you use Station1 as the stream source. That is, the stream source for Station2 is Note When you distribute streams between servers, you must not exceed the distribution limit, the number of MSBD connections that a distribution station can acmodate. By default, a distribution station can support only five MSBD connections to other stations. As you configure stations on remote Windows Media servers to use a distributed ASF stream, you must adjust the distribution station Distribution Limit to acmodate the additional remote connections, or use more than one distribution station as the source for the remote station. For more information about adjusting the Distribution Limit, see Editing station properties. Delivering streams over a nonmulticastenabled work If your work does not use multicast routers, you can multicast a stream only within the work segment that contains Windows Media server ponents. Clients on other segments of the work cannot receive the ASF stream multicast because it does not originate within their segment. Clients throughout the work can still receive the stream if the ASF content is multicast within the local segment, and distributed to Windows Media servers on the other work segments. The station on the local work segment must have both multicast and distribution cap。 該系統(tǒng)在界面設(shè)計(jì)上比較粗糙，整體頁(yè)面布局不夠美觀。 WHERE user_id like 39。 提交和重填 按鈕。 文本框 —— 用來(lái)輸入用戶名。%+user_id+%39。要判斷數(shù)據(jù)庫(kù)中是否存在 投票選項(xiàng) 投票結(jié)果運(yùn)算 編輯 編輯、添加、 刪除 生成最 終結(jié)果 用戶輸入的用戶名，可以在表“ classuser”中統(tǒng)計(jì) user_id 字段的內(nèi)容與用戶輸入的用戶名相匹配的記錄總數(shù)，如果為 0，表示用戶名錯(cuò)誤，提示用戶重新輸：如果不為 0，說(shuō)明用戶名存在，然后進(jìn)入驗(yàn)證密碼步驟。訪問(wèn)的時(shí)間 If vRef= Then vRef = 直接輸入或書簽導(dǎo)入 End If % 圖 45重復(fù)投票提示框 圖 46投票結(jié)果百分比顯示 數(shù)據(jù)導(dǎo)入 圖 47 投票生成圖 用戶管理模塊的設(shè)計(jì) 管理員登錄的設(shè)計(jì)與實(shí)現(xiàn) 設(shè)計(jì)管理員登錄表單 管理員登錄表單由以下 3部分組成 ［ 1］ ： (url) vSoft = (HTTP_USER_AGENT) 39。 ()。 deptid = (dept,j).id+。 } } 得到要?jiǎng)h除的項(xiàng)目的編號(hào)，然后刪除項(xiàng)目 function SelectChk() { var s=false。) (sqldelt) 投票項(xiàng)目已經(jīng)成功刪除 ！ End If % 刪除項(xiàng)目 function sltAll() { var nn = (dept)。 Set rsInsert = (sql) If NOT Then 已經(jīng)存在此投票項(xiàng)目 ,添加失敗 !
