摘要： A failover system, server, method, and computer readable medium are provided. The system includes a primary server for communicating with a client machine and a backup server. The primary server includes a primary session manager, a primary dispatcher a primary order processing engine and a primary verification engine. The method involves receiving an input message, obtaining deterministic information, processing the input message and replicating the input message along with the deterministic information.

摘要： A first remote memory access link is established between a first communications interface card on the first computing device and a second communications interface card on the second computing device. In response to an error associated with the first remote memory access link, messages are copied from a segmented queue associated with the first communications interface card to a segmented queue associated with a third communications interface card on the first computing device. A second remote memory access link between the third communications interface card and a fourth communications interface card is activated on the second computing device, and messages are resent from the segmented queue associated with the third communications interface card to the fourth communications interface card through the second remote memory access link. The second computing device discards duplicate received messages, if any.

摘要： One aspect of the present invention provides a system for failover comprising at least one client selectively connectable to one of at least two interconnected server via a network connection. In a normal state, one of the servers is designated a primary server when connected to the client and a remainder of the servers are designated as backup servers when not connected to the client. The at least one client is configured to send messages to the primary server. The servers are configured to process the messages using at least one service that is identical in each of the servers. The services are unaware of whether a server respective to the service is operating as the primary server or the backup server. The servers are further configured to maintain a library, or the like, that indicates whether a server is the primary server or a server is the backup server. The services within each server are to make external calls via its respective library. The library in the primary server is configured to complete the external calls and return results of the external calls to the service in the primary server and to forward results of the external calls to the service in the backup server. The library in the secondary server does not make external calls but simply forwards the results of the external calls, as received from the primary server, to the service in the secondary server when requested to do so by the service in the secondary server.
摘要翻译：本发明的一个方面提供了一种用于故障切换的系统，其包括经由网络连接选择性地可连接到至少两个互连的服务器中的一个的至少一个客户端。在正常状态下，其中一个服务器在连接到客户端时被指定为主服务器，并且在未连接到客户端时将其余服务器指定为备份服务器。至少一个客户端被配置为向主服务器发送消息。服务器被配置为使用至少一个在每个服务器中相同的服务来处理消息。服务不知道相应服务的服务是作为主服务器还是作为备份服务器运行。服务器还被配置为维护指示服务器是主服务器还是服务器是备份服务器的库等。每个服务器中的服务都是通过其各自的库进行外部呼叫。主服务器中的库被配置为完成外部呼叫并将外部呼叫的结果返回到主服务器中的服务，并将外部呼叫的结果转发到备份服务器中的服务。辅助服务器中的库不会进行外部呼叫，而是在辅助服务器中的服务请求时，将从主服务器接收到的外部呼叫的结果转发到辅助服务器中的服务。

摘要： A writing application on a computing device can reference a tail pointer to write messages to message buffers that a peer-to-peer data link replicates in memory of another computing device. The message buffers are divided into at least two queue segments, where each segment has several buffers. Messages are read from the buffers by a reading application on one of the computing devices using an advancing head pointer by reading a message from a next message buffer when determining that the next message buffer has been newly written. The tail pointer is advanced from one message buffer to another within a same queue segment after writing messages. The tail pointer is advanced from a message buffer of a current queue segment to a message buffer of a next queue segment when determining that the head pointer does not indicate any of the buffers of the next queue segment.
