    Abstract: Embodiments of the present invention provide a data processing method and a data processing device. If to-be-compressed data includes a data fragment that is the same as a first half of a variable block in a duplicate database and is different from a second half of the variable block, a new variable block with granularity smaller than that of the matching variable block can be generated, and the new variable block is added to the duplicate database. The granularity of the new variable block is smaller, which increases the probability of subsequent to-be-compressed data matching the updated duplicate database, thereby improving compression efficiency.

    Abstract: Embodiments of the present application disclose an address processing method. An address allocation device allocates, according to an address allocation request of a service node, a target address block in an idle state in a global address pool to the service node, and sets the target address block to an occupied state. The service node updates a local address pool according to the allocated target address block, and performs address allocation or release for user equipment based on the updated local address pool. When a preset recycling trigger condition is met, the address allocation device obtains recycling information reported by the service node, determines, according to the recycling information, an address block that is in the global address pool and corresponding to the recycling address block.

    Abstract: Embodiments of the present invention provide a method for implementing P2MP multicast, a network node, and a system. The method includes: acquiring, by a network-side leaf node, an mLDP label of a downstream user-side leaf node and FEC information from an mLDP mapping message of the downstream user-side leaf node, then sending an mLDP mapping message that includes an mLDP label and the FEC information, to an upstream network-side root node, and generating a forwarding entry; searching for or establishing an RSVP P2MP LSP, allocating a label to the FEC information, and associating a forwarding entry of each network-side leaf node with the label of the FEC information; and sending an mLDP label of the network-side root node and the FEC information to an upstream user-side leaf node, and associating the mLDP label with the RSVP P2MP LSP and the label of the FEC information.
