Abstract: A method, operable in a framework wherein resources of a content provider may be delivered to clients from at least two distinct content delivery networks (CDNs). Responsive to a client request, one of the CDNs is selected, the selection being based at least in part on one or more policies set by the content provider. The client is provided with information associated with the selected CDN. The information may be a domain name such as a CNAME for the selected CDN. The policies may include a load share policy that specifies a relative load share for each CDN, and the selecting may attempt to satisfy the load share policy. Updated content provider policies may be obtained, at regular intervals.

Abstract translation: 一种可在框架中操作的方法，其中内容提供者的资源可以从至少两个不同的内容递送网络（CDN）传递给客户端。 响应于客户端请求，选择一个CDN，该选择至少部分地基于由内容提供商设置的一个或多个策略。 向客户端提供与所选择的CDN相关联的信息。 该信息可能是一个域名，例如所选CDN的CNAME。 策略可以包括指定每个CDN的相对负载共享的负载共享策略，并且该选择可以尝试满足负载共享策略。 可以定期获取更新的内容提供商策略。

Abstract: An aspect of the disclosure is related to prioritizing users during a server failure. A client device or a central non-regional component detects that a server arbitrating a packet-based voice communication service in a first region has failed, and redirects the client device registered to utilize the packet-based voice communication service in the first region to a second server providing the packet-based voice communication service, wherein the redirecting is based on a priority level of a user of the client device. An aspect of the disclosure is related to peer-assisted failover recovery. A first client device detects that a server arbitrating a packet-based voice communication service in a first region has failed, and notifies a second client device in the first region that the server arbitrating the packet-based voice communication service in the first region has failed.

Abstract: A redundant array of independent nodes are networked together. Each node executes an instance of an application that provides object-based storage. The nodes are grouped into a plurality of systems each having multiple nodes. The systems have one or more replication links each being formed to indicate replication of data from one system to another system in a replicated environment where each system is configured as a sub-domain in a Domain Name System (DNS) infrastructure. A DNS alias synchronization method comprises maintaining updated information, within each system, of all replication links involving that system and of DNS aliases of other systems associated with all replication links involving that system (S602-S607). This enables that system to process network-based requests, on behalf of the other systems, without redirecting the requests from the other systems to that system.

Abstract: The present application is directed towards systems and methods for a user to configure the backup locations to use by an intermediary device providing Global Server Load Balancing (GSLB) services when a primary location is down. In some embodiments, when GSLB is based on static proximity of the location of the client to the GSLB sites and if the primary location is DOWN, then request may be load balanced among all the other locations. But this may not be desirable in many cases. So we need to provide option to the user to specify the preferred list of backup locations to service a client request. The present solution achieves this configurability by using a GSLB policy based on preferred location. One can configure preferred location(s) via a GSLB policy to redirect the client to preferred location(x). One can configure individual policies for different client locations. Based on implementation requirements, one can configure country level granularity, state level granularity and so on.

Abstract translation: 本应用针对的是系统和方法，用于当主位置关闭时，用户配置备份位置以供中间设备提供全球服务器负载平衡（GSLB）服务。 在一些实施例中，当GSLB基于客户端的位置与GSLB站点的静态接近，并且如果主要位置为DOWN时，则请求可以在所有其他位置之间进行负载平衡。 但这在许多情况下可能是不可取的。 因此，我们需要为用户提供选项来指定服务客户端请求的备用位置的首选列表。 本解决方案通过使用基于优选位置的GSLB策略来实现该可配置性。 可以通过GSLB策略来配置优先位置以将客户端重定向到首选位置（x）。 可以为不同的客户端位置配置单独的策略。 根据实现要求，可以配置国家级粒度，状态级粒度等。

Abstract: The present application is directed towards systems and methods for managing ownership of one or more SSL sessions. A cluster of nodes intermediary between at least one client server may maintain a succession list for at least one session of a first client from the at least one client. The succession list may include a list of nodes within the cluster and an order of succession for the nodes to transfer ownership of the at least one session. A first node of the cluster may enter an operational state for managing one or more sessions between the at least one client and the at least one server. A second node of the cluster may initiate, based on the succession list and responsive to the first node entering the operational state, a transfer of ownership of the at least one session from the second node to the first node.

Abstract: An embodiment of this invention provides a new LDAP server control to automate load balancing for replication based directory infrastructure. This solution is applicable to both master-master and master-replica based replication topologies. If one or more of the replication servers or the master servers are available for processing, the request is assigned to them based on output of a weighted non-uniform random number generator. This LDAP server control allows gaining very high performance while doing multiple parallel heavy LDAP operations. This LDAP control prevents the exposure of the replication directory server details to the outer world and therefore proves helpful in easing the security concerns.

Abstract translation: 本发明的一个实施例提供了一种新的LDAP服务器控制，用于自动化基于复制的目录基础设施的负载平衡。 此解决方案适用于基于主主机和基于主复制的复制拓扑。 如果一个或多个复制服务器或主服务器可用于处理，则根据加权的非均匀随机数生成器的输出将请求分配给它们。 此LDAP服务器控件允许在执行多个并行重叠LDAP操作时获得非常高的性能。 此LDAP控制可防止将复制目录服务器详细信息暴露给外部世界，因此有助于缓解安全性问题。
