Description
Technical Field
The present invention relates to the field of optical network information management technologies, and in particular, to a method and an apparatus for managing multicast sinking in an optical network.
Background
An Optical Line Terminal (OLT) of an existing access network adopts a unicast configuration, wherein unicast refers to that a server sends different data according to different requests of each client, the server sends data streams according to each client, and the server traffic is equal to the number of the clients × the client traffic; in the streaming media application with a large number of clients and a large flow of each client, the server cannot support such a huge data stream, the existing network bandwidth is a pyramid structure, and the inter-city provincial trunk bandwidth is only 5% of the sum of all the user bandwidths. If the unicast protocol is used in all, the network backbone will be overwhelmed. Therefore, it is necessary to configure the OLT device with multicast, which is IP multicast (IP multicast), and refers to IP data generated by a single sender (source) and distributed to a group of receivers through the network. From the data format, the multicast and unicast use the common IP message structure and upper layer encapsulation, and only the destination address uses a section of special address space. This segment of address is referred to in IPv4 as class D address space: 224.0.0.0-239.255.255.255. Although seemingly continuous addresses, they cannot be aggregated into network segment addresses, but rather each IP is independently assigned and used. IP multicast is a form of packet delivery between unicast and broadcast that neither specifies an explicit recipient, nor distributes data to all hosts on the network. The sender does not care about the position of the receiver, and the rest of work is handed to the network to be completed as long as the data is sent to the appointed destination address. This has the advantage that the sender only generates one copy of the data, rather than copying one copy for each recipient separately, and the sender does not have to maintain recipient information. The router devices in the network must collect the information of the receivers and implement forwarding and copying of the multicast packets according to the correct path.
An OLT device needs to perform multicast configuration with a plurality of command lines, which are basically more than ten thousand lines, and the existing manual configuration method generates a large workload, and the manual configuration method causes poor normalization, is easy to make mistakes, is not easy to troubleshoot problems such as failure and missed issue, and if the configuration issue mistakes, user faults are affected, and user complaints are caused.
