摘要： A technique that facilitates application synchronization with a reservation protocol at a sender without application receiver participation in a computer network. According to the novel technique, the sender sends a path request message to a reservation receiver and may include a request for fast path failure notification to be returned to the sender. The reservation receiver (e.g., a reservation receiver proxy upstream from the application receiver) receives the path request, and in response, returns a reservation request message to the sender, including a request for fast reservation failure notification also to be sent to the sender (e.g., in response to detecting the fast path failure notification request, local policy/configuration, etc.). In the event that an intermediate node between the sender and reservation receiver detects an error during the path request or reservation request, the intermediate node sends corresponding fast failure notification to the sender. The sender may then synchronize, e.g., an application with the reservation protocol, based on receipt of a fast failure notification or a successful reservation request message.

In an example embodiment, an ingress PE device receives a quality of service (QoS) resource reservation request; constructs an outgoing message that includes information allowing an egress PE device to identify the virtual private network routing and forwarding table (VRF) associated with a resource reservation resulting from the QoS resource reservation request; and transmits the outgoing message to the egress PE device, where the information allowing VRF identification is echoed back by the egress PE device and used by the ingress PE device to identify the VRF associated with the resource reservation resulting from the QoS resource reservation request. Other embodiments are described.

摘要： Recording reconstruction from multiple overlapping recordings may be provided. New recorders may copy manifests from working recorders, as opposed to reconstructing from failed recorders, to construct manifests that refer to video fragments from different recorders. Origin servers may follow these reconstructed manifests to obtain any fragment in the recording, in any combination of recorder failure/take-over/restart, as long as there was at least one recorder functioning at all times.
摘要翻译：可以提供从多个重叠记录的记录重建。新记录员可以从工作记录器复制清单，而不是从失败的记录器重建，以构建引用来自不同记录器的视频片段的清单。只要至少有一台录音机始终运行，原始服务器可以遵循这些重建的清单，以便记录中的任何片段，记录器故障/接管/重新启动的任何组合。
