Problems solved by technology

[0010] 1) The OLT first completes the switching of the encryption enablement of a certain Port-ID, and encrypts the sent data, but the ONU has not completed the switching of the decryption enablement of the Port-ID, so the encrypted data is not decrypted, resulting in data transmission errors
[0011] 2) Before the OLT completes th

Embodiment Construction

[0058] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0059] An embodiment of the present invention provides a method for implementing seamless switching between encryption and decryption, including:

[0060] The port identification encryption and decryption enabled switching mode negotiated between the OLT and the ONU, if the negotiation uses the specified port identification encryption and decryption to enable the switching mode, then the OLT sends a gigabit passive optical network transmission convergence layer GTC frame to the ONU, so The gigabit passive optical network encapsulation form GEM frame included in the above GTC ...

Abstract

The invention provides an encryption/decryption seamless switch achieving method. The encryption/decryption seamless switch achieving method comprises a port identification encryption/decryption enabled switch mode used by negotiation between an optical line terminal (OLT) and an optical network unit (ONU). If the negotiation uses an appointed port identification encryption/decryption enabled switch mode, the OLT can send a gigabit passive optical network transmission convergence layer GTC frame to the ONU. A gigabit passive optical network packing type GEM frame of the GTC frame carries decryption enabled indication to indicate whether the GEM frame needs to be decrypted. The ONU can decide whether the GEM needs to be decrypted according to the decryption enabled indication. The invention further provides an OLT and an ONU.

Description

technical field [0001] The present invention relates to GPON (Gigabit-Capable PON, gigabit passive optical network) system, relate in particular to the implementation method of PORT-ID (port identification) encryption and decryption seamless switching in GPON system, OLT (Optical Line Terminal, optical line terminal) And ONU (Optical Network Unit, optical network unit). Background technique [0002] With the rapid development of information technology, the network has gradually become an indispensable tool for people's daily work and life, so the security requirements for data transmission on the network are also increasing. Since the information network is an open network, the security in the network is particularly important. [0003] The GPON system belongs to an optical network transmission system that is widely used at present. The basic form of the topology structure of the GPON system is bus type, that is, one OLT is connected to multiple ONUs. For a certain user, th...
