Abstract: The present invention provides an address allocation processing method, apparatus and system. The method includes: receiving, by a first BRAS, a DHCP relay packet sent by a second BRAS, wherein the DHCP relay packet includes a gateway IP address and source IP address-based response information; parsing, by the first BRAS, the DHCP relay packet, acquiring the gateway IP address, and allocating an idle IP address from an acquired address pool matching the gateway IP address; encapsulating, by the first BRAS, a source IP address in the DHCP relay packet into a destination IP address in a response packet according to the source IP address-based response information, and sending the idle IP address carried in the encapsulated response packet to the second BRAS. The present invention effectively solve a problem that an address waste phenomenon exists by using a built-in DHCP server in a dual-device hot backup scene.

Abstract: The embodiments of the present disclosure provide a method, a device and a system for data stream transmission, which relate to the field of communication, and can reduce the energy consumption of the data stream transmission between devices. The method includes: receiving, by a resting device, a message indicating to enter into an energy-saving state; after receiving the message indicating to enter into the energy-saving state, sending, by the resting device, stored user information to an on-duty device so that the on-duty device receives and synchronizes user information; and, after the user information is synchronized, setting, by the resting device, the transmission state of the resting device as standby and entering into a sleeping state. The embodiments of the present disclosure are used for data stream transmission.

Abstract: Embodiments of the present application provide a packet processing method in a Point-to-Point Protocol over Ethernet (PPPoE) authentication process and a relevant device. A first broadcast access server (BAS) exists in a broadcast domain in which a user terminal is located, the first BAS supports the PPPoE and corresponds to a first operator. The method includes receiving, by the first BAS, a PPPoE active discovery initiation (PADI) packet sent by the user terminal; and when determining that a quantity of authentication failures of the user terminal on the first BAS is greater than a preset threshold, skipping sending, by the first BAS, a PPPoE active discovery offer (PADO) packet to the user terminal in a preset period. The technical solutions in the embodiments of the present application resolve a problem that the user terminal cannot perform access because the user terminal establishes a session with the first BAS.
