Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 Shown, the flow chart of the method for solving RPC of the present invention to upgrade instability at dual PON ports ONU, the method comprises:

[0026] Step S1: After the ONU is started, query the registration and role status of the two PON ports of the ONU. The role status is divided into ACT and STD status;

[0027] Step S2: The PON port of the ONU is set to be in a dormant state as a logical communication port based on RPC, and a stable connection protocol is created on the basis of the RPC protocol, and the default state of communication is monitoring;

[0028] Step S3: poll the PON port role status change of the ONU in real time, and start the timer if it changes;

[0029] Step S4: After the RPC connection is establ...

Abstract

The invention provides a method for solving upgrading instability of RPC at double-PON-port ONU. The method includes S1: registration and role state of two PON ports of ONU are acquired; S2: the PON ports are set at the state of dormancy; S3: PON port role state change is polled in real time; S4: after the establishment of the RPC connection, a C end transmits transmission upgrading file requests to an S end, a timer is started, the file is transmitted, and S7 is executed at the same time; S5: after the S end receives the request, the upgrading file is started to download and the timer is started; S6: the S end starts the upgrading and the upgrading timer is started, and after the upgrading is completed, S8 is executed; S7: the C end starts to upgrade and the upgrading timer is started; S8: the S end sends upgrading success confirmation to the C end, and then the execution is returned to S2; and S9: the C end is successively upgraded, and after the upgrading success is confirmed, the upgrading success alarm is reported, and the execution is returned to S2. The method recovers the upgrading through bidirectional communication and the starting of timing retransmission and automatic restarting mechanism to guarantee the upgrading file transmission between the double PON ports of the ONU correctly; and moreover, the method is not limited by low-level network technology and can be transplanted to multiple systems.

Description

technical field [0001] The invention relates to the field of Ethernet passive optical network (EPON), in particular to a method for solving the unstable upgrading of RPC in ONU with dual PON ports. Background technique [0002] EPON (Ethernet Passive Optical Network) system is composed of three parts: OLT (Optical Line Terminal), ODN (Optical Distribution Network) and ONU (Optical Network Unit). [0003] In order to meet the high reliability requirements of EPON services for equipment, dual PON ONUs are used to support EPON full protection switching function. Dual PON ONUs contain dual PON MAC chips, which are independent CPU systems, each with Flash running the same program. [0004] RPC (Remote Procedure Call Protocol) remote procedure call protocol, which is a protocol that requests services from remote computer programs through the network without knowing the underlying network technology. RPC adopts the client / server model. A requester is a client, and a service prov...
