本发明实施例的另一种实现防止业务路由器过载的方法如图 4所示， 业务 路由器 A是业务路由器 B的上一跳路由器，业务路由器 B是原处理业务请求消 息 S1 的业务路由器， 因资源限制无法处理新的业务请求消息 S1 , 需要请求消 息其他业务路由器处理该业务。 业务路由器 A, C， D是业务路由器 B相邻的业 务路由器。 当业务路由器 A接收业务请求消息请求业务 S1时， 根据路由表信 息将业务请求消息发送到业务路由器 B, 业务路由器 B对该进行判断， 如果业 务请求消息为新请求消息并且业务路由器 B没有足够的资源处理该请求消息， 则向相邻的业务路由器 C和业务路由器 D发送资源请求消息， 业务路由器 D 由于有足够的资源应答该资源请求消息， 于是业务路由器 B将上述业务 S1的 资源部署消息发送到业务路由器 D, 并且业务路由器 A更新业务 S1路由表信 息。 具体过程包括：
S401 : 业务路由器 A接收到用户或其它业务路由器发送的业务请求消息， 该业务请求消息请求处理业务 S1 , 该业务请求消息包含业务标识。
S402: 业务路由器 A根据业务标识从业务目录中查找该业务所归属的业务 路由器， 并将该业务请求消息发送至该业务归属的业务路由器。
业务路由器 A根据业务标识从业务目录中查找业务 S1所归属的业务路由 器为业务路由器 B, 并根据路由表信息中包含业务路由器 B的地址， 将上述业 务请求消息发送到业务路由器 B。
S403: 业务路由器 B接收该业务请求消息后， 从业务请求消息中获取该业 务标识； 根据该业务标识， 确定该业务路由器 B就是该业务请求消息对应的业 务的归属业务路由器， 则根据业务标识获取业务的状态， 并解析该业务状态， 如果该业务状态是后续的请求消息， 则处理该业务请求消息， 也就是更新该请 求消息业务状态， 比如从业务状态 1转变成业务状态 2, 并将业务请求消息发 送到该业务中； 如果该业务状态是新的请求消息， 则查询获取业务 S1需占用资 源， 并且检查业务路由器 B 自身已使用资源； 如果业务 S1需占用资源与业务 路由器 B自身已使用资源之和高于或等于预设阔值， 则向相邻路由器发送资源 请求消息。 如果业务 S1需占用资源与业务路由器 B 自身已使用资源之和低于 预设阔值， 则处理该业务请求消息。
殳设业务路由器 A 地址 sip@192.168.1.1 , 业务路由器 B 地址 sip@192.168.1.2; 业务 S1归属于业务路由器 B, 业务 ID为 12345。 以内存占 用率为说明资源使用情况， 说明资源使用情况可以有两种表示方式： 可以用资 源占用率， 比如： 业务路由器的内存占用率已经为 80%; 也可以使用资源实际 占用的情况， 比如： 业务路由器的内存已经被占用 1MB ( megabyte, 兆字节）。 如果业务路由器八、 B、 C、 D是完全相同的业务路由器， 这两种方式都可以使 用， 如果业务路由器八、 B、 C、 D的性能是不同的话， 则只能以使用资源实际 占用的情况来做说明， 在本发明实施例中， 假设业务路由器八、 B、 C、 D是完 全相同的业务路由器， 并假设业务路由器 B的资源占用率是 80%, 业务路由器 C的资源占用率是 80%, 业务路由器 D的资源占用率是 20%, 业务 S1的需占 用资源为 10%, 各路由器设定阔值为 90%。 并且假设业务路由器 B分析业务 S1请求消息是新请求消息， 业务 S1的资源占用率为 10%, 而业务路由器 B的 资源占用率是 80%, 路由器设定阔值为 90%。 判断业务路由器 B不能处理该业 务请求消息。
S404: 根据上述业务路由器 B判断不能处理业务 S1 , 则根据路由表信息， 获取业务路由器 B的相邻的业务路由器 C和业务路由器 D的地址，并根据上述 地址向相邻的业务路由器 C和业务路由器 D发送资源请求消息。路由表信息记 载了包括业务路由器的相邻业务路由器地址。
该资源请求消息包括必选项： 消息类型和业务信息， 其中业务信息可以包 含业务标识、 业务地址、 业务状态和业务需占用资源等信息， 资源请求消息还 包括可选项： 上一跳业务路由器地址和有效时间， 其中上一跳业务路由器指的 是， 在业务请求消息在路由过程中， 路由到当前业务路由器的前一个业务路由 器， 例如： 本发明实施例中， 在路由业务 S1的业务请求消息时， 业务路由器 A 就是业务路由器 B的上一跳业务路由器。 资源请求消息具体的参数描述如下： 消息类型： Oc-REQ, 标识该消息为资源请求消息； 业务信息， 包括业务标 识 （identity , ID ) , 业务标识唯一标识该业务， 如 12345 ; 业务地址， 如 sip@weather.web.sina; 业务^ 态， 口 0表示初始^ 态， 也尤是该业务为一个新 业务请求； 业务需占用资源， 如 20, 其中表示内存占有率需要 20%, 业务需占 用资源可以包括： 内存资源占用率， CPU资源占用率， 需占用带宽大小等等， 本发明实施例只是用内存资源占用率来做说明， 其他的资源占用的处理的方法 与之类似。 上一跳路由器地址： sip@192.168.1.1 ; 有效时间： 如 60min, 表示 请求相邻业务路由器分担处理业务 S1的新的业务请求有效时间为 60分钟， 60 分钟的有效时间满后， 业务路由器 B可以重新处理 S1的新的业务请求； 资源请求消息字段格式

S405: 业务路由器 C和业务路由器 D收到该资源请求消息后， 分别分析该 资源请求消息，确定是否有资源处理该业务。其中分析资源请求消息操作如下：
1 )检查自身业务路由器的已使用资源； 例如： 根据本实施例中所假设的， 业务路由器 C的资源占用率是 80%, 业务路由器 D的资源占用率是 20%;
2 )计算输入参数业务 S1的需占用资源与自身已使用资源之和， 并且与阔 值进行比较；
3 )如果输入参数业务 S1的需占用资源与自身已使用资源之和高于或等于 阔值， 则放弃处理业务 S1 , 丟弃该资源请求消息；
例如： 根据本实施例中所假设的， 由于业务 S1 需占用资源为 10%, 则业 务路由器 C自身已使用资源与业务 SI需占用资源之和为 90%,而业务路由器 C 预先设定阔值为 90%, 则业务路由器 C不能处理，放弃处理业务 S1 , 丟弃资源 请求消息。
4 )如果输入参数业务 S1的需占用资源与自身已使用资源之和小于阔值， 则确定可以处理业务 Sl。
例如： 根据本实施例中所假设的， 由于业务 S1 需占用资源为 10%, 则业 务路由器 D 自身已使用资源与业务 S1需占用资源之和为 30%, 而业务路由器 D预先设定阔值为 90%, 则业务路由器 D可以处理业务 Sl。
如果业务路由 B的所有相邻路由器都不能负荷该业务请求消息， 则向业务 路由器 A返回出错消息， 业务路由器 B可以丟弃该业务请求数据包。
S406: 业务路由器 D分析该资源请求消息后， 确认有足够的资源负荷该业 务请求消息， 则向业务路由器 B发送资源应答消息； 其中资源应答消息具体的 参数描述如下：
消息类型： 必选项， Oc-ACK用于表示该消息为资源应答消息； 业务信息， 必选项， 包括业务 ID , 用于唯一标识业务， 如 12345 ; 业务地址， 如 sip@weather.web.sina。 上一跳路由器地址： 可选项， 例如 sip@192.168.1.1 ; 有 效时间： 可选项， 例如 60min, 表示业务路由器 D应答分担处理 SI的新的业务 请求的有效时间为 60分钟， 60分钟的有效时间满后， 业务路由器 B可以重新 处理 S1的新的业务请求。
表 2: 资源应答消息字段格式
Figure imgf000013_0001
S407: 业务路由器 B收到业务路由器 D的资源应答消息后，还可以向业务 路由器 B各个相邻业务路由器发送路由更新消息， 也就是说可以向业务路由器 A, C, D发送路由更新消息， 该路由表更新消息中携带业务路由器 D的地址信 息。 其中路由表更新消息具体的参数描述如下：
消息类型： 必选项， Oc-Update表示该消息为资源应答消息； 替代路由器 地址： 必选项， 例如 sip@192.168.1.1 ; 业务信息， 可选项， 包括业务 ID, 用于 唯一标 i只业务， ¾口 12345; 业务地址， 可选项， ¾口 sip@weather.web.sina。 有效 时间： 可选项， 如 60min, 表示业务路由器 D应答分担处理业务 SI的新的业务 请求设定的有效时间为 60分钟， 60分钟的有效时间满后， 业务路由器 B重新 处理业务 S1的新的业务请求，业务路由器 D就不处理业务 S1的新的业务请求。
表 3: 路由表更新消息字段格式
Figure imgf000014_0001
S408: 业务路由器 A接收路由表更新消息后， 更新路由表信息， 更新业务 S1的路由路径， 将业务 S1的归属业务路由器更新为业务路由器 D, 并设定有 效时间； 更新路由表信息后就启动定时器， 定时到时就将超时地址删除。
S409: 业务路由器 B向业务路由器 D发送资源部署消息和上述请求业务 S1的业务请求消息， 其中资源部署消息包含业务 S1的业务信息， 例如业务 S1 的状态信息， 业务地址 sip@weather.web.sina, 接口， 协议和业务的物理地址信 息等。 资源部署消息的具体的参数描述如下：
消息类型： Oc-Deploy; 有效时间； 业务信息， 包括： 业务 ID, 唯一标识 业务， ^ 12345 , 业务地址， ^ sip@weather.web.sina; 业务^ 态： 0, 表示初始 状态。
表 4: 资源部署消息字段格式
消息类型 业务信息 有效时间
Oc-Deploy 必选 可选 业务 ID: 12345
业务地址： sip(¾.weather.web.sina
Oc-Deploy 60
业务状态： 0
业务的物理地址： 192.168.0.9 本发明另一实施例中，业务路由器 B还可以向业务路由器 D只发送资源部 署消息，该资源部署消息不仅包含业务 S1的业务信息，还可以包含上述业务请 求消息的信息。
这时， 业务路由器 D接收到资源部署消息和上述请求业务 S1的业务请求 消息， 或者只是接收到资源部署消息后， 处理该业务请求消息， 并根据业务 S1 的地址将上述业务请求消息发送到业务 Sl。
S410: 业务路由器 C, D接收到上述业务路由 B发送的路由表更新消息， 更新路由表信息， 以使得在有效时间内 （如果路由更新消息包含有效时间）内， 所有新业务请求消息的原归属业务路由器为业务路由器 B, 并且原本由业务路 由器 C发送给业务路由器 B的该新业务请求消息， 都将转发给业务路由器 D, 由业务路由器 D来处理， 而不发送给业务路由器 B了， 或者所有新业务请求消 息的原归属业务路由器为业务路由器 B, 并且原本由业务路由器 D发送给业务 路由器 B的该新业务请求消息，无需再向业务路由器 B发送该新业务请求消息， 就由业务路由器 D自身来处理该新业务请求消息。
当然 S407与 S409, S410并没有时间上的先后顺序。
此时如果业务路由器 A接收到业务 S1的业务请求消息时， 业务路由器 A 对该业务请求消息进行解析；
1 )如果是初始状态的新业务请求消息，在有效时间范围内则将业务请求消 息路由到业务路由器 D; 如果有效时间过期， 则仍然将业务请求消息发送到业 务路由器^
2 )如果不是新的业务请求消息，则将该业务请求消息发送到业务路由器 B。 本发明实施例中， 业务路由器 B确定自身有没有足够资源处理接收到的业 务请求消息， 如果有， 则表明业务路由器 B处理该业务请求消息后不会过载， 业务路由器 B处理该业务请求， 如果没有， 则表明业务路由器 B处理该业务请 求消息后会导致过载， 则向业务路由器 C, D发送资源请求消息。 然后由业务 路由器判断 C, D是否有资源处理该业务请求， 业务路由器 C没有资源处理该 业务请求， 则第二业务路由器丟弃资源请求消息， 业务路由器 D有资源处理该 业务请求， 则向第一业务路由器返回资源应答消息， 则业务路由器 B接收资源 应答消息后， 向第二业务路由器发送资源部署消息， 由第二业务路由器处理该 业务请求。 这样使得在业务量突增或持续增加的情况下， 仍能保证业务路由器 不会过载， 和不会导致局部业务路由器不可用， 保证业务交互的便捷高效。
通过解析业务请求消息和检查自身可用资源， 判断业务路由器是否可能过 载， 如果可能过载， 则向相邻的业务路由器发送资源请求消息， 以便于相邻业 务路由器处理该业务请求消息。 这样使得在业务量突增或持续增加的情况下， 实现动态处理业务路由器过载， 确保业务路由器的负载均衡和业务交互的便捷 高效。 并且业务路由器的负载均衡实现由业务路由器自身完成， 无需额外的硬 件开销。
本发明另一实施例中， 上述 S408中， 业务路由器 B还可以在收到资源应 答消息后设置中转策略， 也就是业务路由器 B设置一个有效时间， 在该有效时 间内，如果用户或其他业务路由器发送请求业务 S1的业务请求消息时，业务路 由器解析该业务请求为请求 S1的业务请求，则直接将该业务请求转发给业务路 由器 D。 例如： 有效时间为 60分钟， 则在 60分钟内， 业务路由器 B后续接收 到业务 ID为 12345的业务 S1的业务请求消息时， 就直接将该业务请求消息转 发到业务路由器 D, 业务路由器 B只是做为业务 S1的中转路由器。 其他过程 同可以参照图 4对应的实施例。
本发明另一实施例中， 上述 S408中， 业务路由器 D在发送资源应答消息 后可以向业务目录发送发布信息更新消息， 该发布信息更新消息包含业务路由 器 D的地址， 更改业务目录中业务 S1的发布信息， 将业务 S1的归属业务路由 器由业务路由器 B改成业务路由器 D, 并可以进一步设置有效时间， 在有效时 间内，该业务 S1的归属业务路由器就是为业务路由器 D,如果有效时间届满后， 则仍然将该业务 SI的归属业务路由器该为业务路由 B。此时只要在有效时间内， 业务请求者对业务 S1进行业务请求， 根据业务目录中的信息 （业务 S1的归属 路由器在有效时间内是业务路由器 D ), 该业务请求被路由到业务路由器 D。如 果有效时间失效后，业务请求者对业务 S1进行业务请求时，根据业务目录中的 信息 （业务 S1的归属路由器是业务路由器 B ), 该业务请求被路由到业务路由 器 B。后续业务路由器 B或业务路由器 D对该业务请求进行业务处理同上述图 2对应的实施例相同。
在本发明的另一个实施例中， 步骤 S406中， S407中， 业务路由器 D收到 业务路由器 B的资源应答消息后，还可以根据业务路由器 B的各个相邻业务路 由器的地址， 向业务路由器 B的各个相邻业务路由器发送路由更新消息， 业务 路由器 B发送给业务路由器 D的资源部署消息中可以包含业务路由器 B的各个 相邻业务路由器的地址。 该路由表更新消息中携带业务路由器 D的地址信息。 在本发明实施例中业务路由器 B的相邻业务路由器为业务路由器 A、 业务路由 器 C和业务路由器 D,业务路由器 A和业务路由器 C接收到上述路由更新消息 后更新路由表信息， 以使得在有效时间内 （如果路由更新消息包含有效时间） 内， 所有新业务请求消息的原归属业务路由器为业务路由器 B, 并且原本由业 务路由器 A或 C发送给业务路由器 B的该新业务请求消息，都将转发给业务路 由器 D, 由业务路由器 D来处理， 而不发送给业务路由器 B了。 当然业务路由 器 D无需向自身发送路由更新消息， 就可以修改自身的路由表信息， 在有效时 间内 （如果路由更新消息包含有效时间） 内， 所有新业务请求消息原归属业务 路由器为业务路由 B, 并且原本由业务路由器 D发送给业务路由器 B的新业务 请求消息， 无需再向业务路由器 B发送该新业务请求消息， 而直接由业务路由 器 D自身来处理该新业务请求消息。

本发明实施例的另一种业务路由器如图 6所示， 具体包括第二请求消息处 理单元 61和第二负载均衡单元 62。 第二请求消息处理单元 61用于接收第一业 务路由器发送的资源请求消息， 接收所述其他业务路由器发送的资源部署消息 和业务请求消息， 处理所述业务请求消息， 其中， 所述资源请求消息是在所述 第一业务路由器自身没有资源处理所述业务请求消息， 且所述业务请求消息对 应的业务状态为新业务请求时， 由所述第一业务路由器发送的； 第二负载均衡 单元 62, 用于确定自身是否有资源处理业务请求消息， 且在有资处理所述业务 请求消息时向所述第一业务路由器发送资源应答消息。
