Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] The present invention realizes refined service for terminal users by setting bridge port BP and setting the mapping relationship between bridge port BP and PortID. The overall processing flow is: the upstream data packet obtains the BP number of the data packet through the mapping relationship between the PortID and the bridge port BP, then performs MAC+VLAN+BP address learning and forwards the service packet to the GPON OLT; the downstream data packet searches for the MAC+ The address learning table of VLAN+BP obtains the bridge port BP, and then obtains the PortID according to the mapping relationship between the bridge port BP and PortID, divides the downlink service flow into different flows pointing to the PortID, and then performs shaping, enqueuing and scheduling on these service flows, etc. The processing before sending, and then enter the tran...

Abstract

The invention discloses a processing method of Ethernet business in the Jupiter passive optical network, which comprises the following steps: D1. setting the mapping relationship of bridge port and physical port of optical network unit; affirming the corresponding relationship of the distributed address of bridge port and Ethernet business pack; allocating bearing channel mark to mark the property of distributed Ethernet business pack; establishing the mapping relationship between bridge port and bearing channel mark; D2. obtaining the bridge port through the corresponding relationship of the bridge port and the distributed address of Ethernet business pack; D3. acquiring the bearing channel mark through bridge port according to the mapping relationship of bridge port and bearing channel mark; D4. distributing the Ethernet business pack to the optical network unit according to the bearing channel mark. The invention realizes the fine service for terminal user.

Description

technical field [0001] The invention relates to an Ethernet service processing method in Gigabit-capable Passive Optical Network (GPON). Background technique [0002] GPON is a technology in the optical access network, which is composed of three parts: OLT (Optical Line Terminal, Optical Line Terminal), ODN (Optical Distribution Network, Optical Distribution Network) and ONU (Optical Network Unit, Optical Network Unit) , a network architecture in which OLT and ONU are connected through a passive optical distribution network ODN. The service packets from OLT to ONU are sent by broadcasting, and ONU selectively obtains its own service packets and discards other irrelevant data packets; ONU uploads bursty services to OLT in the time slot allocated to itself. Therefore, GPON is actually a one-to-many network structure. GPON uses the bearer channel identifier PortID on the OLT side to identify various services from different ONUs. [0003] At present, the most commonly used app...
