摘要： In a method and appliance for using a dynamic response time to determine responsiveness of one or more network services on a server, a monitor determines a response time for each of one or more network services. The monitor establishes an average response time based on the determined response time for each of the one or more network services. The monitor associates with the established average response time a predetermined threshold for which the response time of the one or more network services may deviate from the average response time and maintain an indication of responsiveness. The monitor monitors the response time of the one or more network services to one or more requests. The monitor determines that the response time of the one or more network services deviates from the average response time by the predetermined threshold. The monitor indicates that the one or more network services are unavailable.

摘要： The present solution provides a centralized configuration of a Global Server Load Balancing (GSLB) site hierarchy that may be batched across a plurality of appliances in a multi-site deployment. A single GSLB site hierarchy configuration may be distributed and operated on each appliance at each site. This reduces the configuration maintained for the multi-site deployment. Furthermore, in this manner, each appliance across multiple sites has an understanding of the entire topology of the multi-site deployment. Responsive to this configuration and understanding, each appliance may perform and optimize operations according to the site topology. For example, the appliances may selectively determine which sites to establish connections with in order to share metrics. In another example, appliances may select which remote sites to monitor services according to the topology.
摘要翻译：本解决方案提供了可以在多站点部署中跨多个设备进行批量的全局服务器负载平衡（GSLB）站点层次结构的集中配置。可以在每个站点的每个设备上分发和操作单个GSLB站点层次结构配置。这减少了为多站点部署维护的配置。此外，以这种方式，跨多个站点的每个设备都了解多站点部署的整个拓扑。响应于这种配置和理解，每个设备可以根据站点拓扑执行和优化操作。例如，设备可以选择性地确定哪些站点建立连接以便共享度量。在另一示例中，设备可以根据拓扑结构选择哪些远程站点来监视服务。

摘要： The present invention provides systems and methods for maintaining site persistence in a hierarchical Global Server Load Balancing (GSLB) deployment. Via configuration of GSLB services locally and remotely on each of the GSLB appliances and LB appliances at a site, a site appliance identifies and associates requests from the GSLB with the site. Furthermore, the site appliance may receive a GSLB cookie with the client request and confirms the request is from the expected GSLB in the site hierarchy. When the load balancers receives a response from a server, the appliance may include the GSLB cookie with the response back to the client. The appliance may also include an LB cookie to identify the server selected by the LB. When the client sends another request, the request may include the GSLB and LB cookie. With this information, the GSLB and LB appliance may maintain site persistence for the client as well as server persistence at the site.

摘要： The present invention provides improvements to the integration between a metric exchange protocol and a monitoring mechanism supporting load balancing by a Global Server Load Balancing (GSLB) appliance in a GSLB hierarchy of appliances, using a method for triggering a monitor on a remote service. The method includes receiving, by a first appliance, metrics of a second appliance via a metric exchange connection between the first and second appliances. The first appliance includes a GSLB service and identifies a service provided via the second appliance as a remote service for GSLB. The first appliance may identify via the metrics that a state of the service is up, and determine that the metric exchange connection is down. Responsive to the determination, the first appliance may trigger a monitor to monitor the status of the service. Further, the first appliance may obtain via the monitor a second status of the service.

摘要： Described are methods and systems for managing the connections between a client, an intermediary appliance and a server, so that asynchronous messages can be transmitted over HTTP from the server to a client. When a connection is established between a client and an intermediary, and the intermediary and a server to establish a logical client-server connection, that logical client-server connection is labeled and not maintained, while the connection between the client and the intermediary is maintained. Messages generated by the server and destined for the client are transmitted to the intermediary along with the connection label. The intermediary can then use the connection label to determine which client should receive the message.
