Problems solved by technology

However, in practical applications, there are some users, especially some large enterprise-level customers, who have multiple offices in the same place, and these offices are far apart, possibly dozens of kilometers apart, and need to For communication, the data traffic may be very large, and it is not realistic to build a local area network by yourself because of the high cost
At present, there is no technical solution for direct P2P communication between each ONT / ONU in the GPON system

Abstract

The invention discloses a method for communicating peer to peer in gigabit-capable passive optical networks, which comprises: building one or a plurality of P2P communication channels which are used for communicating peer to peer between an optical line terminal OLT and an optical network terminal ONT or an optical network unit ONU and transmitting service flows which respectively need carrying out the P2P communication on the OLT and ONT or ONU on the built P2P communication channels. The invention can realize that the P2P communication is carried out between each ONT or ONU under the OLT ina GPON system, data streams do not need transmitting to a higher layer interface or to public networks such as a metropolitan area network or a backbone network, unnecessary wideband occupancies are avoided, and simultaneously the safety of data can be guaranteed.

Description

technical field [0001] The invention relates to the field of network systems, in particular to a peer-to-peer communication (P2P) method of Gigabit Passive Optical Network (GPON). Background technique [0002] Because in the PON (Passive Optical Networks) system, an OLT (Optical Line Terminal) is usually connected to multiple ONTs (Optical Network Terminals) / ONUs (Optical Network Units) through an Optical Distribution Network (ODN, Optical Distribution Network) , generally 1:32, 1:64 or 1:128, etc., usually using a tree structure, using point-to-multipoint communication, that is, communication between OLT and ONT / ONU. [0003] At present, in ITU-T (International Telecommunication Union-T) G.984.1-G.984.3, GPON point-to-multipoint (between OLT and ONT) communication has been stipulated, using ATM (Asynchronous Transfer Mode) or GEM (GPON encapsulation mode) method to encapsulate, and encapsulate the load (eg, Ethernet frame, etc.) into an ATM or GEM frame. For the GEM mode,...
