Embodiment Construction

[0031] In the present invention, the XG-PON system mainly includes the central office equipment OLT and the remote equipment ONU (Optical Network Unit, optical network unit). The OLT is located on the operator side and is used to manage and maintain the access of the ONU; the ONU is located on the user side and provides various service access functions for the user. The OLT in the XG-PON system mainly includes two functional modules according to the function division: PON MAC module and TM module. When processing data flows of different users and different services, the PON MAC module realizes the data flow between the XGEM flow and the Ethernet flow. Mutual mapping, the data flow processed by the TM module is an Ethernet flow, which realizes the flow management function. In the present invention, different user data services are mapped to Ethernet flows with different XGEM Port-IDs, and the XG-PON system implements flow management of Ethernet flows based on XGEM Port-IDs.

Abstract

The invention discloses an XG-PON system flow management device and method. The method comprises the following steps: in the uplink direction, a PON-MAC module maps an uplink XGEM flow into an Ethernet flow and inserts the outermost layer VLAN of which the VLAN ID is equal to XGEM Port-ID; a TM module realizes the uplink flow management based on the XGEM Port-ID, then removes the outermost layer VLAN, and records a mapping relation table of an upper Ethernet flow identification and the XGEM Port-ID; in the downlink direction, the TM module can acquire the corresponding XGEM Port-ID according to an Ethernet identification and the mapping relation table, and insert the XGEM Port-ID to the outermost layer VLAN to realize the downlink flow management; the PON MAC module acquires the corresponding XGEM Port-ID according to the mapping relation table, then removes the outermost layer VLAN and sends the XGEM Port-ID to an ONU (optical network unit). The method disclosed by the invention can effectively ensure the integrity and reliability of the flow management function of the XG-PON system, and meet the requirement on data flow subdivision and reasonable customer service management of operators because the number of users accessed to the net is increased and the service capacity is expanded.

Description

technical field [0001] The present invention relates to a PON system, in particular to an XG-PON system flow management device and method. Background technique [0002] In the context of global informatization, broadband access is developing rapidly. XG-PON technology has become the most representative and widely applicable next-generation optical access technology in the industry. With the increase of access network users and the continuous expansion of equipment, the access network system is becoming larger and larger. Operators are paying more and more attention to the QoS (Quality of Service) of network equipment. How to ensure that the network carries multiple services Transmission reliability, QoS of corresponding services, and reasonable flow management have become the focus of the industry. QoS includes service flow classification, priority marking, queuing and scheduling, traffic shaping, traffic control, congestion avoidance and buffer management, etc., which con...
