Problems solved by technology

Since the EPON standard only supports whole packet transmission, when the ONU uploads data, if the current remaining bandwidth is greater than or equal to the current packet length, it will send the current packet; if the current remaining bandwidth is less than the current packet length, it will not Send the current message until the next time the authorized bandwidth is obtained from the OLT and the obtained authorized bandwidth is greater than the current message length, then the current message is sent, which causes a waste of tail bandwidth, resulting in a decrease in overall throughput

Embodiment Construction

[0019] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0020] see figure 2 , an ONU high-throughput report reporting method, including the following steps:

[0021] Step A: ONU receives the gate message of OLT, extracts the information of the flag field in the gate message;

[0022] Step B: Whether the reported value currently calculated by the ONU is greater than or equal to the configured report sending threshold;

[0023] Step C: if it is greater than or equal to the configured report sending threshold, the ONU sends the report message according to the currently calculated report value, and then enters the next report report;

[0024] Step D: If it is less than the configured report sending threshold, it is necessary to determine whether the flag field in the gate information is mandatory to send the report;

[0025] Step E: Forcibly send the report, the ONU sends the report message according to...

Abstract

The invention discloses a high-throughput report mode of an ONU. The high-throughput report mode comprises the following steps: extracting, by the ONU, information of a flag domain in a gate message,and when the currently calculated report value of the ONU is greater than or equal to the configured report sending threshold value, sending, by the ONU, a report message according to the currently calculated report value; judging whether the flag domain in the gate information forcibly sends the report or not when the flag domain in the gate information is smaller than the configured report sending threshold value; and when the ONU is not forcibly sent, judging whether a report sending timer of the ONU reaches the timeout time or not. According to the invention, when the caching capability ofthe ONU is relatively strong, whether the bandwidth needs to be reported is determined through the threshold value, so that the situation that the OLT frequently issues a small bandwidth to the ONU to cause the waste of a tail bandwidth and further cause the reduction of the whole throughput of the system can be avoided.

Description

technical field [0001] The invention belongs to the technical field of ONU message reporting, in particular to a high-throughput report reporting method of the ONU. Background technique [0002] With the development of passive optical network technology, users have more and more demands on the network, and the number of users is increasing. At the same time, users have greater requirements for bandwidth and higher requirements for delay Therefore, the requirements for dynamic bandwidth allocation of optical line terminals are becoming more and more stringent, and for optical line terminals, the reported value of bandwidth is an important indicator for OLT to perform dynamic bandwidth allocation. [0003] In a passive optical network, an optical line terminal (optical line terminal) is connected to multiple optical network units (optical network units) through a passive splitter (passive splitter). [0004] Such as figure 1 , forming a passive optical network system. For th...
