[0067] 其中,本发明各实施例提及的加速网络中为支持某种或多种网络加速协议或机制的网络,其中,加速网络中的网元为支持某种或多种网络加速协议或机制的网元。 [0067] wherein the network accelerator to accelerate embodiment mentioned protocol or mechanism to support a certain or more embodiments of the present invention, each network a network, wherein the network accelerator to accelerate network element protocol in support of one or more, or the network NE mechanism.

[0068] 其中,上述第一应用层数据包的应用层包头携带的目的互联网数据中心的编号,可为经过加密或未经过加密的目的互联网数据中心的编号。 [0068] wherein a first number of the application layer of the application layer data packet header carries purpose Internet data center may be encrypted or not encrypted via number of objects Internet data center.

[0069] 204、第一网元若利用上述目的互联网数据中心的编号,在由动态路由管理器下发的K条下一跳地址记录之中,获得了与上述目的互联网数据中心的编号匹配的下一跳地址记录,则将上述匹配的下一跳地址记录中记录的下一跳网元通信地址,作为确定出的向上述目的互联网数据中心传输上述第一应用层数据包的路由路径中上述第一网元的下一跳网元的通信地址。 [0069] 204, using the first network element if the number of the above-described object of the Internet data center, among the K recorded by the address of the next hop of the dynamically routing manager, the above object is obtained with the number of Internet data center matches routing path next hop record, a communication address of the next hop network element records the next hop address of the matching will be recorded as the determined application layer of the first transmission data packet to the Internet data center in the above-described object Mailing address next-hop network element of the first network element.

[0070] 当然,若第一网元利用上述目的互联网数据中心的编号,在由动态路由管理器下发的K条下一跳地址记录之中,未获得与上述目的互联网数据中心的编号匹配的下一跳地址记录,则可直接向动态路由管理器请求获取与上述目的互联网数据中心的编号匹配的下一跳地址记录。 [0070] Of course, if the first network element by using the above-described object number of Internet data centers, among the K-hop by the address records issued under dynamic routing manager, is not obtained with the above-described object of the Internet data center that matches the number of next hop record, may request directly to the dynamic routing manager acquires the next hop address the above object recording the number of Internet data center matches. 本实施例中以第一网元利用上述目的互联网数据中心的编号,在由动态路由管理器下发的K条下一跳地址记录之中获得了与上述目的互联网数据中心的编号匹配的下一跳地址记录为例进行描述。 Example number to the first network element using the Internet data center object of the present embodiment, the above object is obtained with the Internet data center to match the number of the next record in the next hop address issued the K under dynamic routing manager jump address records described as an example.

[0071] 在本发明的一些实施例中,加速网络中的各个网元均可定期或者不定期的向动态路由(drouter )管理器上报自身的丢包率、负载和/或传输时延等工作状态,加速网络中的各网元还可向动态路由管理器上报自身与其它加速网络网元之间的互联关系(例如直连或非直连关系)等,以便于动态路由管理器可以知悉加速网络中各网元之间的互联情况,知悉加速网络中各网元丢包率、负载和/或传输时延等工作状态。 [0071] In some embodiments of the present invention, the acceleration of each NE in the network and can be regular or irregular manager reports its packet loss rate, load and / or transmission delay etc. to dynamic routing (drouter) state, the acceleration in the network may be reported by each network element interconnected relationship between itself and other accelerated network element (such as direct connection or direct connection relationship) and the like to a dynamic routing manager, in order to know the dynamic routing manager may accelerate in the case of the interconnection network between the network element, the network knows the accelerated loss rate in each NE, load and / or the like operating state transmission delay. 动态路由管理器可基于最短路径优先协议和/或备选下一跳网元的工作状态等信息,计算出加速网络中的部分或全部网元到某一个或多个目的互联网数据中心的路由路径,进而可以向加速网络中的相应部分或全部网元下发若干条下一跳地址记录(下一跳地址记录中可记录目的互联网数据中心的标识信息和下一跳网元的通信地址等)。 Dynamic routing manager based on Shortest Path First protocol and / or alternatively the next-hop network element operating state information, calculates the acceleration of some or all of the network to a network element one or more destination Internet data center routing path , can be further accelerated to a corresponding portion of the network or network element delivers all address records several next hop (the next hop address may be recorded in the recording information of the destination communication address identification of the Internet data center and next hop NE, etc.) .

[0072] 其中,由于加速网络中的各个网元定期或不定期的向动态路由管理器上报的自身的丢包率、负载和/或传输时延等工作状态可能实时动态的变化,因此若动态路由管理器基于最短路径优先协议和备选下一跳网元的工作状态,来计算出加速网络中的部分或全部网元到某一个或多个目的互联网数据中心的路由路径,则动态路由管理器计算出的某网元到某一个或多个目的互联网数据中心的路由路径可能动态的变化,因此,当计算出的路由路径发生变化时,动态路由管理器可以向加速网络中的相应网元下发最新版本的若干条下一跳地址记录(下一跳地址记录中可记录目的互联网数据中心的标识信息和下一跳网元的通信地址等)。 [0072] wherein, due to the acceleration of each NE in the network regularly or irregularly reports to the dynamic routing manager itself packet loss rate, load and / or transmission delay etc. may be real-time dynamic state changes, so if the dynamic routing manager based on shortest path First alternative next hop and the operating state of the NE, the acceleration is calculated in the network part or all of the network elements to one or more routing path to the destination Internet data center, the dynamic routing management a routing path to one or more destination Internet data center may change dynamically required NE is calculated, therefore, when the calculated routing path changes, dynamic routing, the network manager may accelerate the respective network element issued several pieces of the latest version of the next-hop address records (communication address may be recorded object identification information and Internet data centers and other next-hop network element records the next hop address).
