Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
An embodiment of the present invention provides a method for implementing an asymmetric EPON MAC, as shown in fig. 1, where the method includes:
s101, in a downlink direction, an optical line terminal OLT informs an optical network unit ONU of supporting an uplink 2.5G rate or a 10G rate, and opens a 2.5G rate uplink registration window or opens a 10G rate uplink registration window;
in the downlink direction, the OLT supports two rates of 10G and 1G; in the uplink direction, the OLT supports three rates, i.e., 10G, 2.5G, and 1G, and in the embodiment of the present invention, the uplink 10G rate and the uplink 2.5G rate multiplex one path, and only one path exists at the same time. Namely either 10G/2.5G or 10G/10G, can be mixed with 10G/1G or 1G/1G;
in order to support 10G/2.5G asymmetric EPON registration, as an implementation manner, a DISCOVERY gating message DISCOVERY GATE frame in a registration process can be modified, and the modification needs to ensure that the normal work of the existing 10G/10G, 10G/1G and 1G/1G EPONs cannot be influenced. In the registration stage, 10G EPON protocol distinguishes two rates of upstream 10G and 1G. Now, 2.5G uplink rate is introduced, and three rates of uplink 1G, 2.5G and 10G need to be distinguished.
The OLT can use two reserved bits of a DISCOVERY GATE frame DISCOVERY information domain to inform the ONU of supporting an uplink 2.5G rate or a 10G rate and open a 2.5G rate uplink registration window or a 10G rate uplink registration window; one reserved bit of the two reserved bits is used for indicating that the OLT supports the uplink 2.5G rate or 10G rate; and the other reserved bit is used for indicating that the OLT opens a 2.5G rate uplink registration window or opens a 10G rate uplink registration window.
The two reserved bits may be bit2 and bit6, as shown in table 1. In addition to bit2 and bit6, other reserved bits may be used.
TABLE 1
Because upstream 10G and upstream 2.5G cannot exist simultaneously, bit1 and bit2 can only have 1 bit at most to be 1. Similarly, bit5 and bit6 can only have 1 bit at most to be 1. When the OLT uses the high-speed mode 10G/2.5G, bit1 and bit5 in the table below should be 0, and EPON ONUs operating in the 10G/10G mode cannot register. When the OLT uses the high-speed mode 10G/10G, bit2 and bit6 in the following table should be 0, and the ONU operating in the 10G/2.5G mode cannot complete the registration. The broadcast LLID used when the 10G/2.5G OLT issues the discovery gate is 0x7 FFE.
S102, in the uplink direction, when the OLT supports the uplink 2.5G rate, receiving the notification of the ONU to know whether the ONU supports the uplink 2.5G rate and whether to attempt to register the uplink 2.5G rate; when the OLT supports the upstream 10G rate, the notification of the ONU is received to know whether the ONU supports the upstream 10G rate and whether to attempt to register the upstream 10G rate.
Similarly, to support 10G/2.5G asymmetric EPON registration, as an implementation, the REGISTER _ REQ frame in the registration process may be modified, where the modification is required to ensure that the normal operation of the existing 10G/10G, 10G/1G, and 1G/1G EPONs is not affected.
The OLT learns whether the ONU supports the uplink 2.5G rate and tries to REGISTER the uplink 2.5G rate or whether the ONU supports the uplink 10G rate and tries to REGISTER the uplink 10G rate by analyzing a Discovery Information field of a REGISTER _ REQ frame sent by the ONU; the discovery information field uses two bits, wherein one bit is used for indicating whether the ONU supports the uplink 2.5G rate or whether the ONU supports the uplink 10G rate, and the other bit is used for indicating whether the ONU attempts to register the uplink 2.5G rate or whether the ONU attempts to register the uplink 10G rate.
The two bits may be bit1 and bit5 as shown in table 2.
TABLE 2
In the uplink direction, the uplink REGISTER _ REQ frame Discovery Information field sent by the ONU may not use the new bit, such as bit1 and bit5, but the OLT needs to change the parsing manner of bit1 and bit 5. The meaning of Bit1 is that ONU supports upstream 10G, and ONU supports upstream 10G or 2.5G. The meaning of bit5 is that the ONU tries to register upstream 10G, and becomes ONU trying to register upstream 10G or 2.5G. When the OLT issues the DISCOVERY GATE frame, which already indicates whether the upstream high-speed channel is 10G or 2.5G, the ONU with unmatched rate does not send the REGISTER _ REQ frame, so that it is not necessary to distinguish whether bit1 and bit5 correspond to 10G or 2.5G. The broadcast LLID used when a 10G/2.5G ONU transmits REGISTER _ REQ upstream is 0x7 FFE. Of course, the uplink REGISTER _ REQ frame Discovery Information field sent by the ONU may also use the reserved bit to notify the OLT whether it supports the corresponding uplink rate itself and whether it attempts to REGISTER the corresponding uplink rate.
By adopting the method of the embodiment of the invention, 10G/2.5G asymmetric EPON can be realized, a scheme that the uplink rate is 1G- >2.5G- >10G for smooth upgrade and flexible use is provided, and a user has a further selection space in bandwidth selection. In addition, the cost of the optical module of 10G is high, while the cost of the optical module of 2.5G rate is much cheaper, and is closer to that of 1G. The 2.5G uplink can multiplex the logic of 10G EPON MAC, and the chip area and the power consumption are not increased additionally. Therefore, the cost of the uplink 2.5G and the uplink 1G is close, and the performance is greatly improved.
An embodiment of the present invention further provides another asymmetric EPON MAC implementation method, as shown in fig. 2, where the method includes:
s201, in a downlink direction, an optical network unit ONU receives a notice which is sent by an optical line terminal OLT and indicates that the ONU supports an uplink 2.5G rate or a 10G rate, and opens a 2.5G rate uplink registration window or opens a 10G rate uplink registration window;
as an implementation manner, the ONU learns that the OLT supports an uplink 2.5G rate or 10G rate by analyzing a discover GATE frame DISCOVERY field sent by the OLT, and opens a 2.5G rate uplink registration window or opens a 10G rate uplink registration window; the discovery information domain uses two reserved bits, wherein one reserved bit is used for indicating that the OLT supports an uplink 2.5G rate or a 10G rate; and the other reserved bit is used for indicating that the OLT opens a 2.5G rate uplink registration window or opens a 10G rate uplink registration window.
The two reserved bits may be bit2 and bit6, as shown in table 1;
s202, in an uplink direction, an ONU sends a notification to an OLT on whether to support an uplink rate and whether to attempt to register the uplink rate, when the ONU can support the uplink rate and match the uplink rate supported by the OLT;
as one implementation, the ONU informs the OLT whether to support the upstream rate and whether to attempt to REGISTER the upstream rate using two bits of the Discovery Information field of the REGISTER _ REQ frame; one bit is used for indicating whether the ONU supports the uplink 2.5G rate or whether the ONU supports the uplink 10G rate, and the other bit is used for indicating whether the ONU attempts to register the uplink 2.5G rate or whether the ONU attempts to register the uplink 10G rate.
The two bits may be bit1 and bit5, as shown in table 2.
By adopting the method of the embodiment of the invention, 10G/2.5G asymmetric EPON can be realized, a scheme that the uplink rate is 1G- >2.5G- >10G for smooth upgrade and flexible use is provided, and a user has a further selection space in bandwidth selection. In addition, the cost of the optical module of 10G is high, while the cost of the optical module of 2.5G rate is much cheaper, and is closer to that of 1G. The 2.5G uplink can multiplex the logic of 10G EPON MAC, and the chip area and the power consumption are not increased additionally. Therefore, the cost of the uplink 2.5G and the uplink 1G is close, and the performance is greatly improved.

as an implementation manner, the downlink unit 301 is configured to notify the ONU itself to support an uplink 2.5G rate or a 10G rate by using two reserved bits of a DISCOVERY GATE frame DISCOVERY information field, and open a 2.5G rate uplink registration window or open a 10G rate uplink registration window; one reserved bit of the two reserved bits is used for indicating that the OLT supports the uplink 2.5G rate or 10G rate; and the other reserved bit is used for indicating that the OLT opens a 2.5G rate uplink registration window or opens a 10G rate uplink registration window. The two reserved bits may be bit2 and bit6, as shown in table 1.

as an implementation manner, the upstream unit 301 is configured to learn, by parsing a Discovery Information field of a REGISTER _ REQ frame sent by an ONU, whether the ONU supports an upstream 2.5G rate and whether to attempt to REGISTER the upstream 2.5G rate, or whether the ONU supports an upstream 10G rate and whether to attempt to REGISTER the upstream 10G rate; the discovery information field uses two bits, wherein one bit is used for indicating whether the ONU supports the uplink 2.5G rate or whether the ONU supports the uplink 10G rate, and the other bit is used for indicating whether the ONU attempts to register the uplink 2.5G rate or whether the ONU attempts to register the uplink 10G rate. The two bits may be bit1 and bit5, as shown in table 2.

The 2.5G uplink can multiplex the logic of 10G EPON MAC, and the chip area and the power consumption are not increased additionally. Therefore, the cost of the uplink 2.5G and the uplink 1G is close, and the performance is greatly improved.
