[0039] This embodiment provides a VLAN centralized control method of an EPON network, which changes the OLT and the remote node ONU connected to it into a simple device that only retains the data plane, realizes stream forwarding, and moves the VLAN control planes of these nodes to the SDN Controller, SDN controller informs OLT and ONU which mode they are working in through the expanded Openflow flow table, so as to meet the VLAN standard of China Telecom EPON equipment. The method in this embodiment will be described in detail below.

[0040] Such as figure 1 As shown, the VLAN centralized control method of the EPON network includes the following steps.

[0041] Step S11, introducing an SDN controller in the EPON network and connecting the SDN controller to the OLT in the EPON network; wherein SDN (Software Defined Network, software-defined network) is a new network innovation architecture of the Emulex network, its core technology Openflow realizes flexible control of netw...

Abstract

The present invention provides a VLAN centralized control method and system of an EPON network, the method comprising: introducing an SDN controller into the EPON network; adding whether to support a specific VLAN standard field, the VLAN mode of the OLT and the ONU work in the Openflow flow table field and tag field; add Translation list, VLAN Aggregation list, and action type of VLAN entry rules in Openflow flow table; The message is sent to the specified OLT and / or ONU; the OLT and / or ONU forwards and processes the corresponding message according to the predefined field configuration in the Openflow flow table. The configuration of the VLAN behavior of the EPON system in the present invention is relatively efficient and simple.

Description

technical field [0001] The invention relates to the field of network technology, in particular to the field of EPON network technology, and specifically relates to a VLAN centralized control method and system of an EPON network. Background technique [0002] The further development of broadband services has created demand for operators to increase broadband speed. You may have noticed that the phone lines in your home have been gradually replaced by fiber optics. And EPON is an important technology to realize fiber-to-the-home. [0003] EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network), as the name implies, is an Ethernet-based PON technology. It adopts point-to-multipoint structure, passive optical fiber transmission, and provides multiple services on Ethernet. EPON technology is standardized by the IEEE802.3EFM working group. In June 2004, the IEEE802.3EFM working group released the EPON standard - IEEE802.3ah (incorporated into the IEEE802.3-20...
