The present invention provides a multicast method and a multicast device. The method includes: receiving a multicast request from a user, where the multicast request includes multicast channel information and a user VLAN tag; selecting a first target multicast VLAN from pre-configured multiple multicast VLANs; after replacing the user VLAN tag in the multicast request with the first target multicast VLAN tag, forwarding the multicast request to a multicast router; receiving multicast traffic sent by the multicast router through the first target multicast VLAN, and forwarding the multicast traffic to the user. In the present invention, a target multicast VLAN is selected according to multicast channel information, so that multicast requests for the same multicast channel can be added to the same multicast VLAN. In this way, only one copy of multicast traffic of the same channel exists on a local area network, thereby saving network bandwidth resources.

Multicast method and multicast device

The present invention discloses a call center system and a method for obtaining interface invoke information to realize automatic analysis of the user behaviors. The method includes steps of sending a connection establishment request message to a user interface server by a call center client after a service is activated; allocating a connection identification for the activated service and sending a response message after the user interface server receives the connection request message; performing interactions between the call center client and the user interface server and recording the interaction message according to the connection identification attached in the interaction message; and decomposing the recorded interaction message and obtaining the information on the application programming interface invoked by each service according to the name of the application programming interface corresponding to the interface identification obtained from each message.
