Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a P2MP access network and a method for enhancing its security and a branch / coupler, so as to overcome the P2MP access network system in the prior art when the user terminal has uncontrolled abnormalities or the network is affected When a hacker attacks, the failure terminal or attack point cannot be located, and there are no effective measures to ensure that other users in the P2MP access network system are not affected

Embodiment Construction

[0045] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0046] When the uplink channel of the P2MP access network is congested, it is very difficult to locate the fault point or attack point at the head end, and even if the fault point or attack point is located, the countermeasures that can be taken are extremely passive. Notify the user to cut off the power of the user terminal or take action against the hacker. The present invention starts with the branch / coupler of the distribution network, designs a brand-new branch / coupler, and proposes a method for effectively solving the above-mentioned potential safety hazards. The topology structure of the PM2P access network after introducing the intelligent branch / coupler is as follows: Figure 4 shown. The intelligence of the intelligent branch / coupler is mainly reflected in that when it detects that a certain user terminal has continuously sent uplink data exce...

Abstract

This invention discloses one point to point interface internet and its safety method ad branch coupler composed of one test module, process module and switch module, wherein, the interface network comprises user terminal device, one head end, one align net and at least one branch coupler; The method comprises the following steps: testing each branch upper signals and if certain signal continuous send time is over set time then judging user terminal abnormal cases; connecting branch and coupler switch branch and head end in upper direction and continuing upper signal testing; when the upper signals send time isn't over set time connecting the branch and head end.

Description

technical field [0001] The invention relates to the field of P2MP (Point to Multi-Point, point-to-multipoint) access network, in particular to a P2MP access network, a method for enhancing its security, and a branch / coupler. Background technique [0002] At present, in the access network, there is a downlink (from the head end to the user terminal direction) using TDM (Time Division Multiplex, time division multiplexing) broadcast mode and uplink (from the user terminal direction to the head end direction) using shared bandwidth TDMA (Time Division Multiple Access, Time Division Multiple Access) network, typical examples include HFC (Hybrid Fiber-Coaxial, fiber / coaxial hybrid network) network, xPON (Passive Optical Network, Passive Optical Network) network. This network is a point-to-multipoint structure, and its system components include head-end, distribution network and user terminal equipment, and its topology is generally as follows figure 1 As shown, according to spec...
