A detection method based on a network service, a device, a program product, and a storage medium, relating to the technical field of Internet and used for detecting a network service system. The network service system comprises an access point device cluster and a plurality of intermediate network devices connected to the access point device cluster; at least one Anycast address is configured for the access point device cluster; different Anycast addresses correspond to different types of network services; different types of network services indicate that a destination end is accessed by means of different network paths; and each network path involves one or more intermediate network devices. The method comprises: sending to an Anycast address a plurality of Anycast detection packets accessing a destination end; upon successfully receiving the Anycast detection packets, access point devices in an access point device cluster sending the Anycast detection packets to the destination end on the basis of a target Anycast address in the Anycast detection packets by means of a target network path corresponding to the target Anycast address; and on the basis of the number of successfully responded Anycast detection packets among the plurality of Anycast detection packets, determining whether a network service system is normal.

A content distribution system as discussed herein includes one or more instances of communication management hardware. The communication management hardware tracks a status of multiple different groupings of edge nodes in a content delivery network. Each of the edge nodes is operative to distribute content (such as video content, video segments, digital assets, etc.) in a network environment. The communication device is redirected to the communication management hardware for selection of an appropriate edge node to deliver content to the communication device. To provide load balancing, the communication management hardware selects an appropriate edge node from the different available edge nodes in different edge node clusters. The communication management hardware then communicates an identity of the selected edge node to the communication device. The communication device then communicates with the selected edge node to retrieve the content.

The application discloses a selection method and system of a multi-door lock pan-tilt, the method comprising: according to a video connection request sent by a user APP to a anycast address, selecting an optimal door lock through anycast routing to establish an initial connection, and receiving a connection response containing a device identifier, a router ID and a transaction ID; according to a pan-tilt control requirement initiated by the user APP, constructing a control connection request with the router ID as a destination address and carrying the device identifier and the transaction ID, and forwarding the request to a specific door lock through a transaction ID mapping mechanism of the router; according to a connection confirmation message returned by the specific door lock, establishing a session path binding based on the router ID and the transaction ID; and according to a session path binding state, ensuring that an instruction is accurately sent to the specific door lock through address conversion of the router. By using the embodiment of the application, the accuracy of pan-tilt control instruction transmission, the connection reliability and the overall expansibility of the system can be improved.

This provides a method for identifying a load balancer to select a cache within a Content Delivery Network (CDN) to use to deliver requested objects to a user. [Solution] The method involves the user device performing a DNS lookup to identify anycast IP addresses of multiple load balancers in the CDN, initiating anycast routing using the anycast IP address, and automatically identifying the nearest load balancer. Once the identified load balancer selects a cache, it closes the anycast connection with the user device and uses an HTTP redirect to provide the user device with a unicast route to the selected cache. The user device then establishes a unicast connection with the cache to retrieve an object (e.g., stream).

This invention discloses a method and system for reliable acquisition of mineral video from mobile devices. Each mobile device is configured with the same anycast service IP address. A gateway router establishes a record list including the mobile device's identifier, IP address, and MAC address, and announces the mobile device's connection information to the network. When a client requests a video stream from a mobile device, the gateway router receives the request message, finds the corresponding MAC address based on the mobile device's identifier and IP address, and sends the request to the mobile device. When a mobile device switches its connected wireless access point during movement, the second gateway router after the switch announces the mobile device's connection information to the network, while the first gateway router before the switch announces the cancellation of the mobile device's connection information to the network. This invention effectively enhances the reliability of video data transmission from mobile devices in mining environments, achieving an effective mechanism for uninterrupted and reliable video data acquisition even during gateway switching scenarios.

The specification provides a network service-based probing method, device, program product and storage medium, relates to the technical field of Internet, and a network service system comprises an access point device cluster and a plurality of intermediate network devices connected with the access point device cluster; the access point device cluster is configured with at least one Anycast address, and different Anycast addresses correspond to different types of network services; different types of network services refer to accessing a destination through different network paths, and the network path comprises one or more intermediate network devices; the method comprises the following steps: sending a plurality of Anycast probing packets for accessing the destination to the Anycast address; in the case that the Anycast probing packet is successfully received, the access point device sends the Anycast probing packet to the destination through a target network path corresponding to a target Anycast address based on the target Anycast address in the Anycast probing packet; and whether the network service system is normal is determined based on the number of successful responses in the plurality of Anycast probing packets.
