Abstract: The present application is directed towards ASDR table contract renewal. In some embodiments, a core may cache an ASDR table entry received from an owner core such that when the entry is needed again the core does not need to re-request the entry from the owner core. As storing a cached copy of the entry allows the non-owner core to use an ASDR table entry without requesting the entry from the owner core, the owner core may be unaware of an ASDR table entry's use by a non-owner core. To ensure the owner core keeps the ASDR table entry alive, which the non-owner core has cached, the non-owner core may perform contract renewal for each of its recently used cached entries. The contract renewal method may include sending a message to the owner core that indicates which cached ASDR table entries the non-owner core has recently used or accessed. Responsive to receiving the message the owner core may reset a timeout period associated with the ASDR table entry.

Abstract translation: 本申请针对ASDR表合同续订。 在一些实施例中，核可以缓存从所有者核心接收的ASDR表条目，使得当再次需要该条目时，核心不需要从所有者核心重新请求条目。 由于存储条目的缓存副本允许非所有者内核使用ASDR表条目，而不从所有者核心请求条目，所有者核心可能不知道ASDR表条目由非所有者内核使用。 为了确保所有者核心保持ASDR表条目活着（非所有者核心已经缓存），非所有者核心可以为其最近使用的每个缓存条目执行合同续订。 合同更新方法可以包括向所有者内核发送消息，指示哪个高速缓存的ASDR表条目是非所有者内核最近使用或访问的。 响应于接收消息，所有者核心可以重置与ASDR表条目相关联的超时时间段。

Abstract: The present disclosure is directed towards systems and methods for managing application delivery in a network. A device intermediary to a client and one or more servers that provide a plurality of applications, receives a request from the client to access a first application of the plurality of applications. The device holds the request and retrieves, while holding the request, configuration information for an instance of the first application from a configuration repository. The device configures a virtual internet protocol (“VIP”) server using the configuration information for the instance of the first application. The device processes the request via the VIP server.

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 a method for using a listening policy for a virtual server on an intermediary device. An intermediary device establishes for a first virtual server a first listening policy with an expression for evaluating packets received by the intermediary device to determine whether the packet may access the first virtual server. The intermediary device listens for packets at a first internet protocol (IP) address and a first port specified for the first virtual server. Then, the intermediary device evaluates the expression of the first listening policy to a first packet received at the first IP address and first port and determines whether to provide the first packet to the first virtual server based on a result of the evaluation.

Abstract: The present disclosure presents systems and methods for maintaining original source and destination IP addresses of a request while performing intermediary cache redirection. An intermediary receives a request from a client destined to a server identifying a client IP address as a source IP address and a server IP address as a destination IP address. The intermediary transmits the request to a cache server, the request maintaining original IP addresses and identifying a MAC address of the cache server as the destination MAC address. The intermediary receives the request from the cache server responsive to a cache miss, the received request maintaining the original source and destination IP addresses. The intermediary identifying that the third request is coming from the cache server via one or more data link layer properties of the third transport layer connection. The intermediary transmits to the server the request identifying the client IP address as the source IP address and the server IP address as the destination IP address.

Abstract: The present invention is directed towards systems and methods for using a distributed hash table to maintain the same configuration and resource persistency across a plurality of cores in a multi-core system. The distributed hash table includes a plurality of partitions, each partition being owned by a respective core of the multi-core system. A core may establish resources in the partition it owns. A core may request other cores to establish resources in the partitions they own and send resource information to the core. The core may locally cache the resource information.
