Abstract: A method for detecting a multicast service flow includes receiving, by a first node, a multicast service flow from a multicast source; encapsulating, by the first node, an In-situ Flow Information Telemetry (IFIT) extension header into a data packet in the multicast service flow, where the IFIT extension header includes a first detection identifier, and the first detection identifier is used to identify the detected multicast service flow; copying, by the first node according to a quantity of next-hop second nodes of the first node, the data packet encapsulated with the IFIT extension header; and sending, by the first node to each next-hop second node, the data packet encapsulated with the IFIT extension header. The first node is a head node in a multicast detection domain.

Abstract: The present disclosure discloses a method, a system, and a scheduling server for content delivery, and pertains to the field of multimedia technologies. The method includes: receiving a service request for accessing content; selecting, according to service processing information of one or more devices storing the content, one device to respond to the service request, where the service processing information includes at least one of the number of services successfully processed, a percentage of services successfully processed, the number of services unsuccessfully processed, and a percentage of services unsuccessfully processed; and base upon the selection, sending the received service request to the selected device. The present disclosure may not only improve the percentage of services successfully processed, but also prevent waste of resources and reduce unnecessary service loss, therefore serving users better.

Abstract: A method for realizing paging in a mobile switching center (MSC) pool includes the following steps. An MSC server selects a media gateway (MGW) from more than one MGW connected to a base station controller (BSC)/radio network controller (RNC), delivers a paging message of an international mobile station identity (IMSI) paging type to the selected MGW, and stores a corresponding relation between an IMSI carried in the paging message and the MSC server in the MGW which is connected to the BSC/RNC and does not receive the paging message. The MGW that does not receive the paging message receives a paging response message sent by the BSC/RNC, determines an MSC server corresponding to an IMSI carried in the paging response message by looking up the corresponding relation between the IMSI and the MSC server stored therein, and routes the received paging response message to the corresponding MSC server. Several other methods and devices for realizing paging are also provided.

Abstract: A method for called party recovery in an MSC Pool, applied in a system that comprises an HLR and an MSC Pool including multiple MSC/VLRs, includes configuring a backup server for each MSC/VLR in the MSC Pool; if an MSC/VLR serving a user is down, the user has not initiated any calling service or location update and the user is called, further includes: the HLR sending a call signaling to the backup server of the MSC/VLR that is down; the backup server of the MSC/VLR initiating a paging request to the user and initiating a location update for the user to the HLR; the HLR registering user data of the user at the backup server and switching the MSC/VLR serving the user to the backup server. The present invention also discloses other methods, systems and devices, which can solve the problem of called party recovery in the MSC Pool.
