Abstract: Instead of utilizing a centralized server or hardware(routers/gateways) to enforce connectivity policy restrictions, the policy connectivity restrictions for media session traffic are enforced by an endpoint that is involved in the media communication. Based on the policy requirements, the client enforces the policy restrictions by restricting the candidates that may be selected for the establishment of the media path. For example, the enforcement may result in the client selecting a path from available candidates that avoids congested Wide Area Network (WAN) links, avoiding a low bandwidth link, or possibly even failing the communication completely. The clients may also provide periodic updates to the policy server to allow tracking of the utilization of managed WAN links.

Abstract: The present disclosure relates to systems, methods, and computer-readable media for pre-provisioning server nodes of a server rack and causing the pre-provisioned server node to be deployed on an edge zone of a cloud computing system. In particular, systems described herein involve identifying server nodes based on a customer hardware deployment request and performing a series of pre-provision acts to the server nodes in accordance with the received hardware deployment request. For example, systems described herein pre-provision the hardware by configuring hardware and software on the server nodes, establishing communication with one or more control planes on a datacenter, and bringing the server nodes to a return to web (RTW) state. By pre-provisioning the hardware, the server hardware may be delivered and transitioned to a live state in an efficient manner and without jeopardizing security on the cloud.

Abstract: A media session between an initiating endpoint and a responding endpoint is effected, there being a plurality of available paths through a communication network via which the media session could be established. Type metrics associated with the available paths convey the directness of the available paths and are for making a selection of an available path for the media session. Network information indicative of the quality of the available paths and collected from a plurality of network nodes comprises contributions from network nodes other than the initiating and receiving endpoints which have current and/or have had past visibility of at least parts of the available paths. Said selection is influenced so as to cause the endpoints to select for the media session a higher quality but less direct available path in favor of a more direct but lower quality available path.

Abstract: A media session between an initiating endpoint and a responding endpoint is established via a communication network. A set of candidate pairs is generated, each comprising a respective network address available to the initiating endpoint and a respective network address available to the responding endpoint by exchanging network addresses between the initiating endpoint and the responding endpoint. The media session is established using a candidate pair of the set determined to be valid. Connectivity checks are performed for at least one candidate pair of the set to determine whether or not the candidate pair is valid. The at least one candidate pair is selected in dependence on selection data pertaining to at least one of the network addresses and indicative of the quality of a path through the network that would be traversed were that network address to be used for the media session.

Abstract: Instead of utilizing a centralized server or hardware (routers/gateways) to enforce connectivity policy restrictions, the policy connectivity restrictions for media session traffic are enforced by an endpoint that is involved in the media communication. Based on the policy requirements, the client enforces the policy restrictions by restricting the candidates that may be selected for the establishment of the media path. For example, the enforcement may result in the client selecting a path from available candidates that avoids congested Wide Area Network (WAN) links, avoiding a low bandwidth link, or possibly even failing the communication completely. The clients may also provide periodic updates to the policy server to allow tracking of the utilization of managed WAN links.

Abstract translation: 不采用集中式服务器或硬件（路由器/网关）来强制执行连接策略限制，媒体会话流量的策略连接限制由媒体通信中涉及的端点执行。 根据策略要求，客户端通过限制可能被选择用于建立媒体路径的候选者来强制执行策略限制。 例如，执行可能导致客户端从可用的候选者中选择一条路径，以避免拥塞的广域网（WAN）链路，避免低带宽链路，甚至可能甚至完全失败通信。 客户端还可以向策略服务器定期更新，以便跟踪受管WAN链路的利用率。
