Problems solved by technology

[0005] At present, business isolation on the PON system is mainly realized by dividing VLAN (Virtual Local Area Network, virtual local area network), but the static division of VLAN is easy to be detected, and corresponding equipment can also send data of the same VLAN to intrude into the corresponding VLAN There are certain security risks in the network

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] see figure 2 As shown, the embodiment of the present invention provides a method for network security protection of PON bearer backhaul of small base stations, including the following steps:

[0032] S1. Plan a VLAN address pool in the PON system. The range of the VLAN address pool is: 1 to 4095. This VLAN address pool is specially used for the backhaul network of the user small base station, and does not overlap with other business VLANs;

[0033] see image 3 As shown, in the VLAN address pool, the VLAN configured for common data services is 100, and the VLAN pool for user small base station backhaul services is 200-4000;

[0034] S2. Designate the port number of the ONU (Optical Network Unit, Optical Network Unit) carrying the backhaul service of the small base station. The port of the designated ONU is dedicated to carry...

Abstract

The invention discloses a network safety protection method of PON carrying small base station backhaul and a system thereof and relates to the passive optical network field. The method comprises the following steps of programming a segment of VLAN address pool in a PON system, wherein the VLAN address pool is especially used by a user small base station backhaul network and is not overlapped with VLANs of other services; assigning an port number of ONU carrying a small base station backhaul service, wherein an assigned port of the ONU is especially used for carrying the small base station backhaul; regularly and dynamically designating a VLAN number of the small base station backhaul service by the PON system and dynamically issuing VLAN configuration to a corresponding port of the ONU; and after the ONU receives the VLAN configuration, dynamically generating corresponding configuration and realizing communication of the small base station backhaul service. In the invention, isolation among different services in the PON system can be realized.

Description

technical field [0001] The present invention relates to the field of passive optical networks, in particular to a method and system for network security protection of backhaul of small base stations carried by PON. Background technique [0002] PON (Passive Optical Network, Passive Optical Network) technology is the latest generation of broadband passive optical integrated access standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. An ideal technology for broadband and comprehensive transformation of access network services. see figure 1 As shown, the PON system can provide users with multiple services such as data, voice, and IPTV (Internet Protocol Television, IP TV / Interactive Network TV), and truly realize the integration of the three networks. [0003] Small base station is a small, low-power cellular technology. It is mainly used in indoor places such as homes and SME offices through fixed-line broadband ...
