Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other.
The steps illustrated in the flowchart of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, while a logical order is depicted in the flowchart, in some cases, the steps depicted or described may be performed in a different order than presented herein.
The embodiment of the invention provides a method for realizing an asymmetrical EPON MAC, as shown in figure 1, which comprises the following steps:
s101, in the 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 a 10G rate uplink registration window;
in the downlink direction, the OLT supports two rates, namely 10G and 1G; in the uplink direction, the OLT supports three rates, namely 10G, 2.5G and 1G, and in the embodiment of the present invention, one channel is multiplexed between the uplink 10G rate and the uplink 2.5G rate, and only one channel can exist at the same time. Namely, 10G/2.5G and 10G/10G can be mixed with 10G/1G and 1G/1G;
in order to support 10G/2.5G asymmetric EPON registration, as an implementation manner, a DISCOVERY selection report DISCOVERY GATE frame in a registration process can be modified, and the modification needs to ensure that the normal operation of the existing 10G/10G, 10G/1G and 1G/1G EPONs is not affected. The registration phase, 10G EPON protocol has differentiated between the two rates of upstream 10G and 1G. Now 2.5G upstream rates are introduced, and it is necessary to distinguish between the three upstream 1G, 2.5G and 10G rates.
The OLT may use two reserved bits of the discover GATE frame DISCOVERY information field to inform the ONU itself to support the upstream 2.5G rate or 10G rate, and to open the 2.5G rate upstream registration window or open the 10G rate upstream registration window; one of the two reserved bits is used for indicating that the OLT supports an uplink 2.5G rate or a 10G rate; another reserved bit is used to indicate that the OLT opens a 2.5G rate upstream registration window or opens a 10G rate upstream 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.
Figure BDA0001858921400000051
TABLE 1
Since uplink 10G and uplink 2.5G cannot coexist, bit1 and bit2 can only have 1 bit at most to be 1. Likewise, bit5 and bit6 can only have at most 1 bit as 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 registration. The broadcast LLID used when the 10G/2.5G OLT issues a discovery gate is 0x7FFE.
S102, in the uplink direction, when the OLT supports the uplink 2.5G rate, receiving a 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, a 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.
Also, to support 10G/2.5G asymmetric EPON registration, as an implementation, the REGISTER_REQ frame in the registration flow may be modified, which needs to ensure that normal operation of the existing 10G/10G, 10G/1G and 1G/1G EPONs is not affected.
The OLT knows whether the ONU supports the uplink 2.5G rate and whether the ONU tries to REGISTER the uplink 2.5G rate or whether the ONU supports the uplink 10G rate and whether the ONU tries to REGISTER the uplink 10G rate by analyzing the Discovery Information domain of the REGISTER_REQ frame sent by the ONU; the discovery information field uses two bits, one bit is used to indicate whether the ONU supports an upstream 2.5G rate or whether the ONU supports an upstream 10G rate, and the other bit is used to indicate whether the ONU attempts to register an upstream 2.5G rate or whether the ONU attempts to register an upstream 10G rate.
The two bits may be bit1 and bit5, as shown in table 2.
Figure BDA0001858921400000061
TABLE 2
In the upstream direction, the upstream register_req frame Discovery Information field sent by the ONU may not use new bit, for example, bit1 and bit5 are continuously used, but the parsing mode of the OLT for bit1 and bit5 needs to be changed. Bit1 has meaning that an ONU supports upstream 10G and an ONU supports upstream 10G or 2.5G. bit5 means that the ONU tries to register upstream 10G, and then the ONU tries to register upstream 10G or 2.5G. When the OLT issues a discover GATE frame, it has been shown whether the upstream high speed channel is 10G or 2.5G, and the rate-mismatched ONU will not send a register_req frame, so there is no need to distinguish whether bit1 and bit5 correspond to 10G or 2.5G. The broadcast LLID used when the 10G/2.5G ONU transmits the register_req upstream is 0x7FFE. Of course, the upstream register_req frame Discovery Information field sent by the ONU may also use the reserved bit to inform the OLT whether to support the corresponding upstream rate and whether to attempt to REGISTER the corresponding upstream rate.
By adopting the method provided by the embodiment of the invention, 10G/2.5G asymmetric EPON can be realized, and a scheme of smoothly upgrading and flexibly using the uplink rate 1G- >2.5G- >10G is provided, so that a user has a further selection space in the aspect of bandwidth selection. In addition, the optical module cost of 10G is high, while the optical module cost of 2.5G rate is relatively much cheaper, and is relatively close to 1G. The 2.5G uplink can multiplex the logic of the 10G EPON MAC without additionally increasing the chip area and the power consumption. Therefore, the uplink 2.5G and uplink 1G costs are close, and the performance improvement is larger.
The embodiment of the invention also provides another method for realizing the asymmetrical EPON MAC, as shown in figure 2, which comprises the following steps:
s201, in the downlink direction, an optical network unit ONU receives a notice sent by an optical line terminal OLT and used for indicating that the ONU supports uplink 2.5G rate or 10G rate and opening a 2.5G rate uplink registration window or opening a 10G rate uplink registration window;
as an implementation manner, the ONU learns that the OLT supports the upstream 2.5G rate or the 10G rate by parsing a discover GATE frame DISCOVERY information field sent by the OLT, and opens a 2.5G rate upstream registration window or opens a 10G rate upstream registration window; the discovery information domain uses two reserved bits, one of which is used to indicate that the OLT supports an upstream 2.5G rate or 10G rate; another reserved bit is used to indicate that the OLT opens a 2.5G rate upstream registration window or opens a 10G rate upstream registration window.
The two reserved bits may be bit2 and bit6, as shown in table 1;
s202, in the uplink direction, the ONU sends a notice of whether the uplink rate is supported or not and whether the uplink rate is attempted to be registered or not to the OLT under the condition that the ONU can support the uplink rate to match with the uplink rate supported by the OLT;
as one implementation, the ONU uses two bits of Discovery Information field of register_req frame to inform OLT whether to support the upstream rate and whether to attempt to REGISTER the upstream rate; one bit is used to indicate whether the ONU supports an upstream 2.5G rate or whether the ONU supports an upstream 10G rate, and the other bit is used to indicate whether the ONU attempts to register an upstream 2.5G rate or whether the ONU attempts to register an upstream 10G rate.
The two bits may be bit1 and bit5, as shown in table 2.
By adopting the method provided by the embodiment of the invention, 10G/2.5G asymmetric EPON can be realized, and a scheme of smoothly upgrading and flexibly using the uplink rate 1G- >2.5G- >10G is provided, so that a user has a further selection space in the aspect of bandwidth selection. In addition, the optical module cost of 10G is high, while the optical module cost of 2.5G rate is relatively much cheaper, and is relatively close to 1G. The 2.5G uplink can multiplex the logic of the 10G EPON MAC without additionally increasing the chip area and the power consumption. Therefore, the uplink 2.5G and uplink 1G costs are close, and the performance improvement is larger.

The two reserved bits may be bit2 and bit6, as shown in table 1.
