Abstract: The present disclosure presents systems and methods for obtaining metric information by a multi-core GSLB intermediary device and providing global server load balancing services using the obtained information. A first core of a multi-core GSLB appliance establishes a transport layer connection to a remote load balancer at a site of a plurality of sites. The first core transmits a message to each of the other cores of the multi-core GSLB appliance that the first core is a master core for receiving metric information from the load balancer. The first core receives metric information of the remote site from the load balancer. The first core propagates the metric information to each of the other cores of the GSLB appliance. A GSLB virtual server on a slave core receives a DNS request. The GSLB virtual server determines a DNS resolution for the DNS request based on the metric information.

Abstract: The present application is directed towards systems and methods for adaptive application provisioning for cloud services. An appliance deployed in a network as a gateway may be able to transparently monitor application activity in a cloud computing environment provided by one or more servers, including servers executed by virtual machines, bare-metal or non-virtual servers, or other computing devices. In some embodiments, the appliance may monitor one or more network metrics, including bandwidth usage, latency, congestion, or other issues; and/or may monitor application health or server or virtual machine statistics, including memory and processor usage, bandwidth usage, latency, or other metrics. Responsive to one or more metrics exceeding a threshold, the appliance may automatically provision or start, or deprovision or shut down, one or more virtual or physical machines from a cloud service provider, and may provide configuration information to the provisioned or started machines as needed.

Abstract: The present solution allows users, such as administrators to configure slow start parameters for new services. These slow start parameters specify a rate at which requests should be given to a newly added or up service. The users can also chose to automatically increase the load in multiples of the chosen rate by specifying an increment interval. The services are given the configured rate for the interval, and once the interval is reached, the next multiple of the rate of requests is given. The increase of rate of requests is done automatically until an existing service request rate is reached. At that point in time this functionality is disabled and the existing and new services are treated the same.

Abstract translation: 本解决方案允许用户（如管理员）为新服务配置慢启动参数。 这些缓慢启动参数指定了向新添加或上传服务提供请求的速率。 用户还可以通过指定增量间隔来选择自动增加所选速率的倍数。 给定服务的时间间隔的配置速率，一旦达到间隔，给出请求速率的下一倍。 请求率的增加自动完成，直到达到现有的服务请求率。 在这个时间点，此功能被禁用，现有的和新的服务被视为相同。

Abstract: The present invention is directed towards systems and methods for providing multiple modes of a zone for DNSSEC by an intermediary device. The method includes providing, by a device intermediary to a plurality of clients and a plurality of servers, a plurality of modes of a zone for Domain Name Service. The device receives a selection of a first mode of the zone of the plurality of modes of the zone. The device receives information identifying to enable DNS Security for the selected first mode. The device establishes the zone for DNS in accordance with the selected first mode and with DNS Security enabled.
