Embodiment Construction

[0043] The present invention mainly provides a method, and the main idea is: in the present invention, after the switching device determines that the destination MAC address of the data packet from the source user equipment is bound to the port receiving the data packet, according to the service identifier of the data packet, Determine whether to filter the data packets, and then send the data packets that do not need to be filtered to the destination user equipment through the receiving port, so that in the EPON system, the ONUs belonging to the same OLT can be selectively implemented on the second layer according to the service identification. Intercommunication or Layer 2 isolation.

[0044] The present invention proposes a data packet transmission method applied to a system including a switching device and at least two user equipments, the at least two user equipments belong to the same OLT, and the OLT is connected to the switching device, so described method as figure ...

Abstract

The invention discloses a data package transmission method which comprises the following steps: a data package forwarding mode and a data filtering strategy are configured by an exchange device; the exchange device receives a data package from source user equipment by a port, and the data package contains a service identification and a target media access control (MAC) address; the exchange devicejudges whether the target MAC address is bound with a port, if so, whether the data package is filtered or not is judged according to the service identification of the data package, and if not, the data package is sent to target user equipment by the port. The invention realizes selective two-layer mutual communication or two-layer separation to optical network units (ONUs) belonging to a same optical line terminal (OLT) according to the service identification in an Ethernet passive optical network (EPON) system. The name of the invention is the data package transmission method and the systemand the device thereof.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for data packet transmission. Background technique [0002] In the EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) system, the OLT (Optical Line Terminal, optical line terminal) is connected to the backbone Ethernet through the switching device in the uplink, and several optical fibers are split out through the optical splitter in the downlink. The optical fiber is connected to an ONU (Optical Network Unit, optical network unit), and each ONU is connected downstream with user equipment such as a PC (Personal Computer, personal computer) or telephone equipment. After the user data enters the ONU from the user equipment, the ONU sends it upstream to the OLT through the optical fiber, and the OLT sends the user data upstream to the switching device, and finally the switching device sends the user data to other OLTs...
