Abstract: A broadband access means with a built-in video service unit. Said built-in video service unit transmits the stored video service to the user terminal through the broadband access means it belongs according to the request of user terminal. Said video service unit comprises a unicast storage module; a unicast forward module, for transmitting the video service stored in the unicast storage module to the user terminal according to the unicast request of the user; a unicast retransmission module, for responding the retransmission request of the user terminal and retransmitting the lost unicast video message to the user terminal; a multicast storage means, for caching the multicast video stream in real time; and a multicast retransmission module, for responding the retransmission request of the user terminal and retransmitting the lost unicast video message to the user terminal via unicast traffic.

Abstract: A method for implementing the integrated service access in the broadband access network includes: firstly, in the broadband access network, at least one Label Switching Path LSP is created based on the Muli-Protocol Label Switching MPLS; then, in the broadband access node equipment, the traffic to be transmitted is encapsulated with MPLS and transmitted in the broadband access network via LSP. By using MPLS as the broadband access network creating and the private means for passing through the core network, the present invention could nicely solve the confronting problems as using the broadband access network as integrated service bearing network and implement the integrated service bearing of the IP video, voice, data, private line (including IP private line and conventional Asynchronous Transfer Mode ATM private line, Time Division Multiplexing TDM private line, Frame Relay FR private line) with low cost, because MPLS is a technology that provides multi-layer connection.

Abstract: A method of the ethernet technique exchanging and forwarding, including at least an ethernet forwarding mode is provided, the ethernet forwarding mode includes the standar ethernet forwarding, multiplexing ethernet forwarding, thi-level route forwarding, spanning vlan multicast forwarding and point-to-point vlan forwarding, point-to-point double vlan forwarding; and includs the steps: A1?inputting the ethernet message to the user-side port or the network-side port; A2 ?the port processing the message according to the terminal property list, so that the message finally has the vlan tag which distributed in a unified way by the port; A3?the port determining the forwarding mode of the message according to the tag, and then transmitting the message to the corresponding forwarding plan; A4?the forwarding plan determining the forwarding port of the message, and strategy processing being supplied to the specific ethernet controlled message according to the controlled message capturing strategy; A5?forwarding the message to the output port, and then packing it according to the port property list. By the above scheme, the invention can be applied to the telecommunication network solution.
