背景技术
随着计算机网络技术的发展，给人们生活工作带来了很多的便利。
运营商提供的网络可以分为三类，分别为BGP(边界网关协议)带宽、CDN(内容分发网络)带宽和静态带宽，BGP带宽价格较为昂贵，提供的服务也较稳定，且具备三网互通的能力；CDN带宽较便宜但提供的服务相对不够稳定，静态带宽介于两者之间。
虽然BGP提供的服务较为稳定，但成本较为昂贵。国内主流的运营商包括电信、移动和联通，一个互联网数据中心要同时承载来自多家运营商的流量，所以一个互联网数据中心要有和多家运营商通信的能力。为屏蔽运营商细节，很多互联网数据中心都采用BGP接入，通过BGP网络，部署在互联网数据中心的后端服务器不用考虑流量来自于哪家运营商可以实现网络互通。但BGP网络的造价非常昂贵，是静态网络的数倍，对于很多互联网公司而言，BGP带来的网络成本开销是十分巨大的。

在本场景示例中，上海联通手机用户、天津电信手机用户和北京移动手机用户分别使用手机向调度系统发送接入点询问请求。发送的接入点询问请求中包括三个用户手机各自IP地址。
在本场景示例中，调度系统在采用BGP接入网络的接入设备中提取IP地址和相应的网络运营商信息，形成IP数据集。
在本场景示例中，调度系统分别接收到这3个手机用户使用手机发送的接入点询问请求。提取这三个手机用户各自手机的IP地址，查询IP数据集，得到这三个用户对应的网络运营商分别是中国联通、中国电信和中国移动。
在本场景示例中，调度系统选取上海联通接入点地址、北京联通接入点地址嘉兴联通接入点地址发送给上海联通手机用户的手机，将上海联通接入点地址作为第一接入点地址，将北京联通接入点地址作为第二接入点地址，将嘉兴接入点地址作为第三接入点地址；选取天津电信接入点地址和廊坊电信接入点地址发送给天津电信手机用户的手机，将天津电信接入点地址作为第一接入点地址，将廊坊电信接入点地址作为第二接入点地 址；选取北京移动接入点地址和石家庄移动接入点地址发送给北京移动手机用户的手机，将北京移动接入点地址作为第一接入点地址。

在本实施方式中，所述客户端可以在向所述第一接入点地址发出网络访问请求失败的情况下，向接收到的第二接入点地址发出网络访问请求，分别正常情况下的网络接入和故障时的网络接入。实现所述客户端可以在静态带宽下对故障接入点的自动容灾，保证用户可以得到稳定的网络服务。
在一个实施方式中，所述访问方法还包括，在所述第二接入点地址访问失败的情况 下，向所述调度系统发送接入点变更请求，以重新获得接入点地址。
在本实施方式中，所述接入点变更请求可以是满足通信协议并遵循一定格式的字符串或代码，其可以用于表示发出该接入点变更请求的客户端向所述调度系统请求变更接入点，来获得不同于之前所述调度系统反馈的接入点地址，并且变更的接入点地址与所述客户端所属于的网络服务提供商相对应。所述接入点变更请求中可以包含所述客户端的地址，已经访问失败的接入点地址。具体地，客户端可以基于Http、TCP/IP等协议，向调度系统发送接入点变更请求。具体地，南京移动用户接收调度系统发送的合肥移动接入点地址和上海移动接入点地址，南京移动用户通过手机先对合肥移动宽带接入点发出网络访问请求，访问失败后再次通过手机向上海移动宽带接入点地址发出网络访问请求仍然访问失败，南京移动用户通过手机向调度系统发出接入点变更请求，接入点变更请求中包含用户地址，访问失败的合肥移动宽带接入点地址和上海移动宽带接入点地址，请求变更之前反馈的这两个接入点地址，请求获得不同于这两个宽带接入点地址的新的宽带接入点地址。
在本实施方式中，所述调度系统在接收到所述客户端发送的接入点变更请求后，可以从所管理的接入点地址中随机或者按照指定规则选择接入点地址，并可以将至少一个不同于之前反馈的接入点地址反馈给所述客户端。
在本实施方式中，所述客户端可以在接收到变更后的至少一个接入点地址后，选择一个接入点地址发出网络访问请求，访问成功则结束，访问失败则可以再次向所述调度系统发送接入点变更请求，直到访问成功。
在本实施方式中，在重新获得接入点地址的步骤中可以包括，所述新获得的接入点地址指向的数据中心可以与之前访问失败的接入点地址指向的数据中心相同，也可以不同。
在本实施方式中，在先反馈的接入点地址都不能让所述客户端成功访问的情况下，由所述客户端发送接入点变更请求，并由所述调度系统反馈新的接入点地址，所述客户端对新接入点地址发送网络访问请求。进一步提高了客户端对于故障接入点的容灾率，保证用户可以得到稳定的网络服务。

在本实施方式中，所述调度系统通过根据所述接入点询问请求，确定客户端对应的网络服务提供商，并将所述网络服务提供商的至少一个接入点地址发送给所述客户端，一方面可以保证客户端可以接收到其所属的网络服务提供商的网络接入点地址，另一方面，提供至少一个接入点地址可以保证在一个接入点出现故障后客户端可以及时使用其他接入点地址进行网络访问。
在一个实施方式中，在确定客户端对应的网络服务提供商的步骤中可以包括：调用IP地址库；所述IP地址库中对应有存储IP地址和网络服务提供商；在所述IP地址库中查询所述客户端的IP地址对应的网络服务提供商。
在本实施方式中，IP地址可以是互联网上网络和主机的逻辑地址。在同一个网络服务提供商提供的网络中不同的客户端可以拥有不同的IP地址；客户端所属的网络服务提供商不同IP地址也不相同。IP地址可以是1个32位的二进制数。在一个网络中客户端、服务器、网络接入点等都可以有IP地址。
在本实施方式中，所述IP地址库可以是一个数据库，数据库可以存储有IP地址和各IP地址所对应的网络服务提供商。各网络服务提供商可以将其所述的客户端IP地址汇总起来，建立数据库形成IP地址库，当所述网络服务提供商新增、变更或者删除客户端IP地址时，可以及时更新所述IP地址库。所述IP地址库可以是一个网络服务商与其相应的客户端IP地址集合也可以是若干网络服务商与其相应的客户端IP地址集合。
在本实施方式中，所述调度系统可以从所述客户端发送的接入点询问请求中确定客户端的IP地址，可以调用所述IP地址库，从所述IP地址库中查找客户端的IP地址，找到客户端IP地址后从IP地址库中确定所述客户端对应的网络服务提供商。具体地，联通手机用户通过手机发送接入点询问请求，调度系统从接入点询问请求中确定用户手机的IP地址，调用IP地址库，从IP地址库中找到该IP地址，对应的网络服务提供商为中国联通。
在本实施方式中，所述调度系统本身不知道客户端属于哪一个网络服务提供商，通过调用IP地址库的方式，确定客户端属于哪一个网络服务提供商，从而可以为客户端反馈准确的接入点地址，提高了用户体验。
在一个实施方式中，在确定客户端对应的网络服务提供商的步骤中可以包括，在IP数据集中查询得出所述客户端的IP地址对应的网络服务提供商；其中所述IP数据集是提取自BGP中的接入设备的IP和网络服务提供商。

在本实施方式中，所述调度系统可以在接收到所述客户端发送的接入点询问请求后，从所述接入点询问请求中确定所述客户端的IP地址，根据所述客户端的IP地址查询所述IP数据集，确定相应的网络服务提供商。
在本实施方式中，通过在采用BGP接入的接入设备中提取IP地址和相应的网络服务商信息，由于提取的IP地址和相应的网络服务商信息是从真实网络中提取出来的，提高了信息的准确定，保证所述客户端能够接收到相应网络服务提供商的接入点地址。
在一个实施方式中，在将至少一个接入点地址发送给客户端的步骤中可以包括，将所述网络提供商的至少第一接入点地址和第二接入点地址发送给所述客户端；其中所述第二接入点地址用于在所述客户端访问所述第一接入点地址失败的情况下使用。
在本实施方式中，所述调度系统可以根据客户端地址确定对应的网络服务提供商，所述网络服务提供商可以有不少于1个的接入点。
在本实施方式中，所述调度系统发送所述至少第一接入点地址和第二接入点地址发送给客户端的方式可以包括，所述调度系统可以从所述网络服务提供商提供的接入点地址中选择两个接入点地址，一个作为第一接入点地址另一个作为第二接入点地址。所述调度系统选择接入点地址的方式可以包括，从所述网络服务提供商提供的接入点地址中随机选择两个接入点地址；从所述网络服务商提供的接入点地址中按照指定的规则选择两个接入点。按照指定规则选择接入点地址可以包括，选择客户端本地的接入点地址和/或与客户端本地区域较为接近的接入点地址；所述调度系统在发送接入点地址之前可以对各接入点地址进行性能检测，选择性能较好的接入点地址。
在本实施方式中，所述第二接入点地址可以用于在所述客户端访问所述第一接入点地址失败的情况下使用。所述客户端可以先向第一接入点地址发出网络访问请求，当出现访问失败的情况时，所述客户端可以直接向所述第二接入点地址发出网络访问请求，两个接入点地址分别用于正常情况下的网络接入和故障情况下的网络接入，提高网络服务的稳定性。
在一个实施方式中，所述方法还包括，接收所述客户端发送的接入点变更请求；所述接入点变更请求表示所述客户端已经得到的接入点地址访问失败；重新向所述客户端发送与所述客户端对应的网络服务提供商的接入点地址。
在本实施方式中，所述调度系统可以接收所述客户端发送的接入点变更请求，所述调度系统接收到所述客户端发送的接入点变更请求后可以再次向所述网络服务提供商获取相应的接入点地址，所述调度系统可以随机选择也可以按照一定方式或规则选择接入点地址，发送至少一个接入点地址给所述客户端，用于所述客户端向新获得的接入点地址发出网络访问请求。
在本实施方式中，所述调度系统可以只要收到所述客户端发送的接入点变更请求，在当前所述相应网络服务提供商有可用的接入点时，就将相应的接入点地址发送给所述客户端，保证客户端可以顺利接入网络，提高网络的稳定性。
在一个实施方式中，所述调度系统在重新向所述客户端发送与所述客户端对应的网络服务提供商的接入点地址的步骤中，发送给所述客户端的接入点地址使所述客户端未进行访问过的接入点地址。
在本实施方式中，所述调度系统可以将所述客户端访问失败的接入点地址备份或者标记为故障接入点地址，所述调度系统在接收到接入点地址变更请求后可以向所述相应网络服务提供商提供的接入点地址，从所述相应网络服务商提供的接入点地址中去除备份的所述客户端访问失败的接入点地址或者被标记为故障接入点地址的接入点地址，再从剩下的接入点地址中选择接入点地址发送给所述客户端。
在本实施方式中，所述调度系统可以将客户端未进行访问过的接入点地址发送给所述客户端。保证客户端不会再次向已经尝试访问且访问失败的接入点地址发出访问，提高了所述客户端访问网络的成功率。
在一个实施方式中，统计发送所述接入点变更请求的客户端所访问失败的接入点访问地址；所述接入点访问地址被认为故障地址；其中，所述故障地址在恢复之前，不再发送给客户端。
在本实施方式中，统计所述客户端所访问失败的接入点地址的方式可以包括，当出现一个客户端访问失败的接入点地址时，所述调度系统记录下该接入点地址，形成一个集合；所述调度系统可以将所述客户端所访问失败的接入点地址标记，使之不同于其他接入点地址，将这些标记的接入点地址集合起来完成统计。
在本实施方式中，所述接入点地址被认为故障地址可以包括，所述调度系统可以将这些客户端所访问失败的地址标记为故障地址。所述调度系统在接收到所述接入点查询 请求或者接入点变更请求时，可以暂时不将这些地址发送给所述客户端。
在本实施方式中，所述调度系统可以等待所述故障接入点修复，当所述故障接入点修复完成并且通过相关网络检测，所述调度系统可以去除故障接入点的故障地址标记，待去除故障地址标记后故障接入点才可以被调度系统发送给所述客户端。
在本实施方式中，将客户端访问失败的接入点地址认为是故障地址，在故障地址被恢复前，不再发送给客户端，提高了发送的接入点地址可以被所述客户端访问的成功率。
在一个实施方式中，所述调度系统对接入点进行状态检测；将所述接入点地址中不符合指定要求的接入点地址作为故障地址；其中，所述故障地址在恢复之前，不再发送给客户端。
在本实施方式中，所述调度系统可以主动对所述网络服务提供商提供的接入点地址进行检测。检测的方式可以包括，使用ping命令进行网络连通性检测，如果接入点没有响应ping命令则接入点地址为故障地址；与接入点建立连接，如果多次连接失败或者连接超时则接入点地址为故障地址。
在本实施方式总，所述指定要求可以包括，接入点地址可以正常进行网络连接。具体地，例如，接入点可以响应ping命令；接入点可以连接成功。
在本实施方式中，所述调度系统可以等待故障地址恢复，待修复完成后再次对故障地址进行检测，直到故障地址通过所述调度系统检测为止。
在本实施方式中，所述调度系统可以主动对接入点地址进行检测，与被动等待客户端反馈哪些接入点地址不能够访问相比进一步提高了发送的接入点地址可以被所述客户端访问的成功率。
在一个实施方式中，所述调度系统对所述故障地址进行检测；在所述故障地址符合使用条件的情况下，恢复所述故障地址作为接入点地址提供给客户端访问。
在本实施方式中，所述调度系统可以待所述故障地址恢复完成后，再次对所述故障地址进行检测，直到所述故障地址恢复到符合接入点使用要求。
在本实施方式中，恢复所述故障地址作为接入点地址提供给客户端访问可以包括，将符合使用条件的故障地址重新添加可以发送给客户端的接入点地址集合中。
在本实施方式中，所述调度系统通过完成对所述故障地址的检测，待检测符合使用要求的情况下再将所述故障地址发送给所述客户端，保证所有的接入点地址都可以被提 供给客户端访问，即使是故障地址，只要在恢复后符合使用要求就可以被提供给客户端访问，节约了网络资源，也提高了客户端访问网络的成功率。
在一个实施方式中，监控各接入点地址的指定参数，以确定整体运行状态。
在本实施方式中，所述指定参数可以是评价网络状况的网络参数。所述指定参数可以包括，流量、QPS、长连数或新建连接数等。
在本实施方式中，所述运行状态可以包括所述各接入点地址所表示的接入点的稳定性、针对客户端反馈接入点地址的及时性、针对客户端反馈接入点地址的准确性。
在本实施方式中，所述调度系统可以根据所述指定参数确定所述接入点地址与调度系统的运行状态。所述调度系统可以对各接入点进行监测，可以得到各接入点地址实时的指定参数大小，根据接入点地址的参数确定整个网络交互是否正常运行。
在本实施方式中，所述调度系统可以监控个接入点地址的指定参数，当有接入点地址的指定参数高于或低于正常值范围时，在接收到所述客户端发送的接入点询问请求或者接入点变更请求时，可以动态调整发送合适的接入点地址给所述客户端，可以协调不同接入点的工作量。具体地，例如，调度系统测试各个接入点的流量，当一个接入点流量过高时，可以导致该接入点满负载工作。另外有一个接入点流量相对较少，调度系统可以在接收到客户端发送的接入点询问请求或者接入点变更请求后，可以以较低的概率发送流量过高的接入点地址给客户端，已较高的概率发送另一个接入点流量相对较少的接入点地址给客户端，从而提高接入点的稳定性以及反馈接入点地址的准确性。
在本实施方式中，通过指定参数可以更加科学准确的确定整体的运行状态，可以根据整体运行状态相应发送合适的接入点地址给所述客户端，使网络资源的合理运用，保证网络服务的稳定性。
在一个实施方式中，所述指定参数包括但不限于：流量、QPS、长连数或新建连接数。
在本实施方式中，所述流量可以是单位时间内通过接入点地址的数据量。流量小可以是该接入点地址处于空闲状态，或者该接入点出现故障；流量大可以是接入点地址处于忙的状态，或者该接入点的数据吞吐量较大。
在本实施方式中，所述QPS可以是在规定的时间内接入点地址的响应请求数。QPS越大说明接入点单位时间内响应请求的数量越多，但QPS过高也可以导致接入点崩溃。
在本实施方式中，所述长连数可以是接入点地址长连接的个数，长连接可以是即使没有数据传输，客户端仍然与接入点地址保持连接。
在本实施方式中，所述新建连接数可以是在单位时间内所能建立连接的数量。所述新建连接数的大小可以影响接入点地址在单位时间内所能建立的最大连接数量。
在本实施方式中，根据流量、QPS、长连数和新建连接数作为指定参数确定接入点的运行状态，由于这四个参数可以有效接入点地址的网络性能，使用这四个参数确定接入点运行状态更加科学和准确。
在一个实施方式中，所述运行状态包括但不限于，所述各接入点地址所表示的接入点的稳定性、针对客户端反馈接入点地址的及时性、针对客户端反馈接入点地址的准确性。
在本实施方式中，所述各接入点地址的稳定性可以为，所述调度系统发送给所述客户端接入点地址后，客户端能否稳定的访问该接入点地址，出现掉线、延时等网络故障的次数越少调度系统发送给所述客户端的接入点地址对应的接入点越稳定。
在本实施方式中，所述针对客户端反馈接入点地址的及时性可以为，所述调度系统在接收到所述接入点地址询问请求后，所述调度系统反馈接入点地址的时间，所述客户端从发送接入点地址询问请求到向接入点地址发出访问请求之间的间隔越小，则针对客户端反馈接入点地址越及时。
在本实施方式中，所述针对客户端反馈接入点地址的准确性可以包括，所述调度系统发送的接入点地址是否与客户端的网络服务商相对应；是否已经准确的分配了不是故障接入点的地址。
