In the description of the present application, unless otherwise specified, the meaning of "plurality" refers to two or more.

Below, the technologies involved in this application are explained for the convenience of readers:

Ethernet: Currently the most widely used LAN communication method, it is also a protocol. The Ethernet protocol defines a series of software and hardware standards to connect different computer devices together. The basic elements of Ethernet equipment networking are switches, routers, hubs, optical fibers and ordinary network cables, as well as Ethernet protocols and communication rules. Its layered model includes application layer, presentation layer, session layer, transport layer and network layer.

Flexible Ethernet Flex E: In recent years, with the rise of services such as cloud computing, video, and mobile communications, users' demands on Internet protocol (internet protocol, IP) networks have gradually shifted from bandwidth-based to service experience, service quality and In terms of networking efficiency. In order to meet the above requirements, Ethernet, as the underlying connection technology, needs to have the following capabilities in addition to maintaining the existing advantages of low cost, high reliability, and operability: Multi-granularity flexible rate: provide more flexible bandwidth granularity ; Decoupling from optical transmission capability: decoupling from the rate of optical transmission network, maximizing the use of existing optical transmission network to realize the transmission and bearing of new ultra-large bandwidth Ethernet interfaces; On the basis of the decoupling of transport capabilities, the simple mapping between Ethernet and optical transport network can simplify the network, improve flexibility, and then realize flexible flow grooming and scheduling optimization; the enhanced service quality capability for multi-service bearer: Ethernet in The channelized hardware isolation function is provided on the physical layer interface, which ensures the isolation of services based on different fragments at the physical layer, further cooperates with the upper layer network/application, and realizes enhanced service quality capabilities under the condition of multi-service bearing. In order to meet the requirements of high-speed transmission, flexible bandwidth configuration and enhanced service quality, the flexible Ethernet technology emerges as the times require. As shown in FIG. 1 , it is a general architecture of Flex E in the prior art.

Flexible Ethernet features include: Bonding: Multiple physical layers (physical layers, PHYs) work together to support higher rates. For example, 8-channel 100GE PHY realizes 800G media access control (media access control, MAC) rate. Channelization: Multiple low-rate MAC data streams share one or multiple PHYs. For example, four MAC data streams of 25G, 35G, 20G and 20G are carried on the 100G PHY, or MAC data streams of 125G, 150G and 25G are multiplexed on three 100G PHYs. Sub-rate: A single low-rate MAC data stream shares one or more PHYs to achieve speed reduction. For example, only 50GMAC data streams are carried on the 100G PHY.

G.Hao: The standard released by ITU-T in recent years, the standard number is G.7044/Y.1347, which is used for OTN to realize the bundling based on ODU0 time slot, that is, the ODUFlex frame structure, which is used to meet the flexible bandwidth requirements of packet services , and supports online lossless bandwidth adjustment for packet services. ODUFlex bandwidth adjustment in G.Hao is a network-side bandwidth adjustment technology that supports end-to-end bandwidth adjustment.

OTN/PeOTN: OTN is based on wavelength division multiplexing technology and organizes the transport network in the network at the optical layer. OTN is a new generation of "digital transmission system" and "optical transmission system" regulated by a series of ITU-T standards such as G.Hao, which solves the problem of traditional wavelength division multiplexing (wavelength division multiplexing, WDM) network without wavelength/sub Poor wavelength service dispatching capability, weak networking capability, weak protection capability, etc. The basic object dealt with by OTN is wavelength-level business, which advances the transport network to a real multi-wavelength optical network stage. Due to the combination of the advantages of optical domain and electrical domain processing, OTN can provide huge transmission capacity, fully transparent end-to-end wavelength/sub-wavelength connection and carrier-level protection, and is the optimal technology for transmitting broadband large-grained services.

The mapping modes between Flex E and OTN include three modes: non-aware mode, termination mode, and sensing mode. The non-aware mode is consistent with the traditional Ethernet interface through PCS in the optical transport network. In this mode, the existing With optical transport network equipment, Flex E can be carried without hardware upgrades, and end-to-end ultra-large bandwidth channels across optical transport networks can be realized based on the bundling function. In the termination mode, the optical transport network senses the Flex E user-side interface and recovers the data flow of the Flex E sub-interface, and then further maps it to the optical transport network for transmission and bearer. This mode is consistent with the bearer of traditional Ethernet interfaces on the optical transport network, and can implement functions such as grooming the traffic of different Flex E sub-interfaces in the optical transport network. The perceptual mode takes advantage of the sub-rate feature of the Flex E. When the flexible Ethernet interface on the user side is mapped in the optical transport network through the perceptual mode, the optical transport network directly discards invalid time slots, extracts the data to be carried according to the bandwidth of the original data stream, and then maps to the dense optical transport network that matches the rate. A wavelength division multiplexing (densewave-length division multiplexing, DWDM) transmission pipeline. Optical transport network equipment needs to be consistent with the configuration of the user-side Flex E interface, so as to perceive the Flex E user-side interface and carry out bearer transmission.

The following assumes that the first network 101 is a flexible Ethernet network and the second network 102 is an optical transport network as an example. , to describe the content of this application in detail. As shown in Figure 3, the bandwidth configuration method may include steps S301-S303:

S301. If it is determined that the network protocol of the first network is a preset network protocol, acquire a first network bandwidth.

Wherein, the first network bandwidth is the network bandwidth allocated for the service to be transmitted in the first network. The service requirement of the service to be transmitted includes the required bandwidth of the service that the customer applies for.

Specifically, first determine the service requirements of the service to be transmitted. The service requirements of the service to be transmitted include service type, service source and destination nodes, service required bandwidth, and the like. According to the above service type and service source and destination nodes, respectively select transmission routes for it in the first network and the second network (for example, select a transmission node and a link for it, and transmit the service on the transmission node and link). After determining the transmission route. Allocate corresponding first network bandwidth to it in the transmission path allocated to it in the first network according to the bandwidth required by the above service, and transmit data to it.

Exemplarily, the first network is Flex E, and Flex E supports Ethernet MAC data streams of various bandwidths (such as 10G, 40G and a×25G data streams, even non-standard rate data streams). After selecting the transmission path in the first network and the second network according to the service type of the service to be transmitted and the service source and destination node, it is determined that the service required bandwidth of the service to be transmitted is 150G, then in the first network for it The first network bandwidth of 150G is allocated to it in the allocated transmission path to transmit data for it. The second network is OTN, and the preset network protocol is Flex E protocol. At this time, the second network can obtain the first network bandwidth of the first network according to a preset network protocol.

In an implementation manner of this step, the service requirement includes the service bandwidth required to transmit the service to be transmitted; before obtaining the first network bandwidth, the method further includes:

Obtain the service bandwidth, where the service bandwidth is the service bandwidth required by the belt transmission service. Allocate the first network bandwidth corresponding to the bandwidth required by the service in the first network according to any one of the following three manners.

Mode 1, the first network bandwidth is determined by bundling:

Obtain multiple third network bandwidths in the first network; wherein, each of the third network bandwidths is smaller than the service bandwidth; if the sum of the third network bandwidths is equal to the service bandwidth, then the multiple The third network bandwidths are combined to obtain the first network bandwidth.

Mode 2, determining the first network bandwidth through a channelization method:

Obtain multiple third network bandwidths in the first network; wherein, each of the third network bandwidths is smaller than the service bandwidth; if the sum of the third network bandwidths is greater than the service bandwidth, the multiple combining the third network bandwidth to obtain the fourth network bandwidth; and splitting the fourth network bandwidth to obtain the first network bandwidth.

Mode 3, determining the first network bandwidth by sub-rate method:

The implementation method of mode 2 is: select two 100G PHYs for the third network bandwidth, and multiplex the MAC data streams carrying 120G and 80G on the two 100G PHYs, that is, after bundling the two 100G PHYs, perform channelization processing .

The implementation method of the third mode is as follows: a 200G PHY is selected as the third network bandwidth, and a 120G MAC data flow is carried on the 200G PHY.

Optionally, the first network bandwidth may also select a 120G PHY, and the MAC data stream is carried on the 120G PHY.

S302. Determine the number of time slots required to be occupied by the service to be transmitted in the second network according to a ratio between the bandwidth of the first network and a first preset parameter.

In an implementation manner of this step, this step may be specifically implemented as: dividing the first network bandwidth by a first preset parameter to obtain a time slot parameter, and rounding up the time slot parameter to obtain the time slot quantity.

Exemplarily, this step can be realized by the formula n=ceiling(B _F /1.24416), wherein, the first preset parameter 1.24416 is the minimum channel rate of ODUflex, the unit is G, and B _F is the first network bandwidth, n It is the number of time slots to be occupied by the corresponding bandwidth of the first network bandwidth in the second network.

S303. Determine a second network bandwidth according to a product of the number of time slots and a second preset parameter.

Wherein, the second network bandwidth is the network bandwidth allocated for the service to be transmitted in the second network.

In an implementation manner of this step, this step may be specifically implemented as: multiplying the number of time slots by a second preset parameter to obtain the second network bandwidth.

Exemplarily, this step can be realized by the formula B _G =n×1.24416, wherein, n is the number of time slots required for the bandwidth corresponding to the first network bandwidth in the second network, and B _G is the second For network bandwidth, the second preset parameter is the same as the first preset parameter.

Exemplarily, the above steps S302-S303 are illustrated as follows:

When the first network bandwidth selects three channels of 40G PHY, the first network bandwidth needs to occupy the number of time slots of the second network n=ceiling(40÷1.24416)×3=99, at this time the second network bandwidth B _G =99×1.24416=123.17184, that is, the bandwidth of the second network at this time is 123.17184G.

When two 100G PHYs are selected for the first network bandwidth, the two 100G PHYs need to be combined and then split to obtain a 120G MAC data flow, and the first network bandwidth needs to occupy the time of the second network. Number of slots n=ceiling(120÷1.24416)=97, at this time the second network bandwidth B _G =97×1.24416=120.68352, that is, the second network bandwidth at this time is 120.68352G.

When a 200G PHY is selected for the first network bandwidth, a 120G MAC data flow needs to be carried on the 200G PHY at this time, and the first network bandwidth needs to occupy the number of time slots of the second network n=ceiling(120÷1.24416) =97, at this time the second network bandwidth B _G =97×1.24416=120.68352, that is, the second network bandwidth at this time is 120.68352G.
