[0032] Figure 2 This is a structural diagram of a multi-stream bandwidth configuration device for 400GE Ethernet according to an embodiment of the present invention. DETAILED DESCRIPTION

[0033] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0034] like Figure 1 As shown, an embodiment of the present invention provides a multi-stream bandwidth configuration method for 400GE Ethernet, including:

[0035] Step 11: Obtain at least two data streams to be encapsulated;

[0036] Step 12, determining the number of data packets transmitted by each of the at least two data flows within a target maximum transmission period;

[0037] Step 13, determining a packet gap register parameter and a number of configuration table entries for each of the at least two data flows according to the number of data packets transmitted by each of the at least two data flows;

[0038] Step 14, obtaining a configured bit rate for each data stream according to the packet gap register parameter and the number of configuration table entries of each of the at least two data streams;

[0039] Step 15: Implement bandwidth configuration for the at least two data streams according to the configured bit rate.

[0040] In this embodiment, the data stream refers to the data stream transmitted by 400GE ultra-high-speed Ethernet. There are generally multiple data streams to be encapsulated, and each data stream has a preset target bit rate bps that is expected to be achieved. Through the multi-stream bandwidth configuration method provided by the present application, the bandwidth of multiple data streams is configured, so that the configured bit rate bps of each data stream can be as close to the pre-configured target bit rate bps as possible. Specifically, the present application adopts the technology of adjusting IFG (frame spacing), such as determining the packet gap register parameters in the above step 13; combined with the software lookup table and conversion algorithm, such as determining the number of configuration table items in the above step 13, the bps algorithm of the precise bandwidth percentage of ultra-high-speed Ethernet is realized. Through the above method of the present application, for the bandwidth of 400G, a minimum granular bps step size of 12Mbps can be achieved, thereby realizing the multi-stream bandwidth configuration of 400GE ultra-high-speed Ethernet.

[0041] In an optional embodiment of the present invention, step 12 may include:

[0042] Step 121 : Determine the number of data packets transmitted by each of the at least two data flows within a target maximum transmission period according to the packet length and utilization rate of each of the at least two data flows.

[0043] Specifically, the number of packets N x =(Pmax*bps m%) / (len x +20), where N x is the number of packets transmitted by data stream x, Pmax is the maximum transmission period, bps m% is the utilization rate, len x For the package leader.

[0044] In this embodiment, since 400GE data streams are all sent in IFG mode, the IFG refers to the packet gap in bytes, with a minimum of 20 bytes (including the preamble).

[0045] Calculate the time slice of each byte at 400GE: (1000 / 390.625) / 128 = 0.02ns;

[0046] The minimum packet gap (including the preamble) is: 20*0.02=0.4ns;

[0047] The minimum packet gap (excluding the preamble) is: 0.4*0.6=0.24ns;

[0048] In the general IFG mode, multiple data streams (IDs) all use the same Ifg parameters, that is, the intervals between packets are the same, where Stream_num = Stream_id, that is, the number of streams is equal to the stream ID.

[0049] In the general FPS (frame rate) mode, (Ifg + len) * 0.02 = 1000000000 / fps. Using the frames per second, calculate the time slice length of each packet, convert it to bytes, and then subtract the packet length to get the Ifg parameter.

[0050] In this application, a bps mode is designed by combining the above two modes, which is implemented in disguised form using the IFG mode.

[0051] Specifically, assume there are three data streams, stream 0, stream 1, and stream 2. Assume the maximum transmission period Pmax in bytes is 0x10000000. The parameters of the three data streams are as follows:

[0052] Stream 0 parameters: stream id = 0, packet length len 0 bytes, utilization bps 0%;

[0053] Stream 1 parameters: stream id = 1, packet length len 1 bytes, utilization bps 1%;

[0054] Stream 2 parameters: stream id = 2, packet length len 2 bytes, utilization bps 2%;

[0055] Here, utilization refers to the proportion of the data flow in bits per second under the set target bps.

[0056] Assume that a total of (N0+N1+N2) messages need to be transmitted within the Pmax period, then:

[0057] Number of packets transmitted by stream 0 N0 = (Pmax*bps0%) / (len0+20), taking the integer part;

[0058] Number of packets transmitted by stream 1 N1 = (Pmax*bps1%) / (len1+20), taking the integer part;

[0059] The number of data packets transmitted by flow 2 N2 = (Pmax*bps2%) / (len2+20), taking the integer part.

[0060] In an optional embodiment of the present invention, determining the packet gap register parameter in step 13 includes:

[0061] Step 131, obtaining a remaining utilization rate according to the utilization rates of the at least two data flows;

[0062] Step 132: Obtain packet gap register parameters according to the remaining utilization, the maximum transmission period, and the total number of data packets of at least two data flows.

[0063] In this embodiment, the remaining utilization is obtained by subtracting the utilization of each of the three data streams from 1. Based on the Ethernet data transmission rules in IFG mode, Ifg-20 = Pmax*(1-bps0%-bps1%-bps2%) / (N0+N1+N2). Therefore, the inter-packet gap register parameter Ifg = Pmax*(1-bps0%-bps1%-bps2%) / (N0+N1+N2)+20.

[0064] In an optional embodiment of the present invention, determining the number of configuration table entries of each of the at least two data flows in step 13 includes:

[0065] Step 133, obtaining the total number of configuration table entries;

[0066] Step 134 : Allocate the total number of configuration table entries according to the ratio of the number of data packets in each data flow to the total number of data packets in all data flows, to obtain the number of configuration table entries for each data flow.

[0067] Specifically, the number of configuration entries n x =M*N x / N 总 , where n x is the number of configuration entries for data stream x, M is the total number of configuration entries, and N x is the number of packets transmitted by data stream x, N 总 The total number of packets in all data flows.

[0068] In this embodiment, for the Stream_num register, its stream configuration table 0 to n has n+1 configuration table entries, and x Stream_ids (stream ids) and corresponding packet lengths can be set through n configuration table entries, which are stored in a 32-byte*n lookup table.

[0069] Assume that M is 4095 and there are still 3 data flows. Then (N0+N1+N2) packets need to be evenly distributed to 4095 configuration table entries. The number of configuration table entries for each flow is as follows:

[0070] n0=4095*N0 / (N0+N1+N2), round to the integer, precision: 1 / 4095=0.0244%;

[0071] n1=4095*N1 / (N0+N1+N2), take the integer, precision: 1 / 4095=0.0244%;

[0072] n2=4095*N2 / (N0+N1+N2), take the integer, precision: 1 / 4095=0.0244%.

[0073] In an optional embodiment of the present invention, step 14 may include:

[0074] Step 141, according to the number of configuration table entries of the at least two data flows, distribute each data flow in the order of data flow identification IDs interleaved until all data flows are allocated, thereby obtaining a configuration list;

[0075] Step 142: Obtain the configured bit rate of each data stream according to the configuration list and the packet gap register parameters.

[0076] In this embodiment, each data stream ID is interleaved and distributed in sequence according to the order of each data stream ID. For example, the three data stream IDs mentioned above are interleaved and distributed in the order of 0 / 1 / 2. When the number of configuration table entries occupied by a certain ID in the configuration list reaches the number of pre-allocated entries, the allocation of the stream ID is completed, and the remaining IDs are interleaved. For example, when stream 1 occupies n1 configuration table entries in the configuration list, the allocation of stream 1 is completed. Continue to allocate stream 0 and stream 2 until the three data stream IDs are allocated in M ​​stream configuration table entries, and each stream ID occupies n. x Configuration table entries are generated to obtain a configuration list. This configuration list, combined with the calculated inter-packet gap register parameter Ifg, can be used to assemble the configured bps for each data stream. The error between the configured bps and the target bps is 0.0244%. The higher the value of the configuration table entry, the higher the bps accuracy (the smaller the value). Accuracy can be improved by increasing the number of configuration table entries.

[0077] The method described above utilizes interframe gap (IFG) technology to intelligently combine multiple data streams to create a single stream ID. This method utilizes IFG mode logic combined with a software lookup table and a conversion algorithm to achieve the precise bit-per-second (bps) rate specified for a specific stream ID. Compared to methods that solely use IFG mode to control the interframe gap to achieve 400GE bandwidth line speeds, this method can configure bps for each stream ID within multiple streams, enabling a wider variety of ultra-high-speed Ethernet frame combinations and better simulating precise Ethernet multi-stream bandwidth configurations that meet practical requirements.
