    • Synchronization of configuration files of a virtual application distribution chassis, includes: processing a configuration command received by a master blade; updating a first configuration file with the configuration command and an updated tag by the master blade; sending a configuration message by the master blade to the slave blades informing of the updated configuration file, the configuration message comprising the updated tag; in response to receiving the configuration message by a given slave blade of the one or more slave blades, comparing the updated tag in the configuration message with a tag in a second configuration file stored at the given slave blade; and in response to determining that the updated tag in the configuration message is more recent than the tag in the second configuration file stored at the given slave blade, sending a request for the updated configuration file to the master blade by the given slave blade.
    • 虚拟应用分发机箱的配置文件同步包括:处理主刀片接收的配置命令; 使用配置命令更新第一配置文件和由主刀片更新的标签; 将所述主刀片的配置消息发送到所述从属刀片,通知所述更新的配置文件,所述配置消息包括所述更新的标签; 响应于由一个或多个从属刀片的给定从属刀片接收配置消息,将配置消息中的更新标签与存储在给定从属刀片上的第二配置文件中的标签进行比较; 并且响应于确定配置消息中的更新的标签比存储在给定从属刀片中的第二配置文件中的标签更新,由给定从属刀片向主刀片发送对更新的配置文件的请求。

    • Each service in a computer network may have a connection rate limit. The number of new connections per time period may be limited by using a series of rules. In a specific embodiment of the present invention, a counter is increased each time a server is selected to handle a connection request. For each service, connections coming in are tracked. Therefore, the source of connection-request packets need not be examined. Only the destination service is important. This saves significant time in the examination of the incoming requests. Each service may have its own set of rules to best handle the new traffic for its particular situation. For server load balancing, a reset may be sent to the source address of the new connection request. For transparent cache switching, the connection request may be forwarded to the Internet.
    • 计算机网络中的每个服务可能具有连接速率限制。 每个时间段的新连接数可以通过使用一系列规则来限制。 在本发明的具体实施例中,每当选择服务器来处理连接请求时,增加计数器。 对于每个服务,跟踪进入的连接。 因此,不需要检查连接请求数据包的来源。 只有目的地服务很重要。 这样可以节省大量时间来检查传入的请求。 每个服务可能有自己的一套规则,以便为特定情况最好地处理新的流量。 对于服务器负载平衡,可以将重置发送到新连接请求的源地址。 对于透明缓存切换,连接请求可以被转发到因特网。
