The embodiment of the application provides an Ethernet data interaction method, which comprises data interaction in an uplink direction and data interaction in a downlink direction, wherein fig. 1 is a flow chart of steps of the uplink data interaction in the Ethernet data interaction method according to the embodiment of the application, and as shown in fig. 1, the data interaction in the uplink direction comprises the following steps:
step S102, receiving an Ethernet service flow, wherein the Ethernet service flow is carried through a small particle pipeline;
it should be noted that fig. 2 is a schematic flow chart of the small-particle device carrying the ethernet service, and as shown in fig. 2, when the small-particle device carries the ethernet service, one large-particle pipeline physical port on the network side is only connected with one network-side ethernet physical port of the switch chip inside the small-particle device. In order to implement independent two-layer processing of each small-particle pipeline service, multiple virtual two-layer ethernet ports (e.g., virtual ethernet ports Veth in the embodiment) need to be extended to correspond to the small-particle pipelines.
In step S102, specifically, fig. 3 is a schematic flow chart of uplink data interaction in the ethernet data interaction method according to an embodiment of the present application, as shown in fig. 3, in the small-particle device, ethernet traffic flows (such as traffic flow 1 and traffic flow 2) of different users are received through a user side port of the small-particle device, and the ethernet traffic flows are forwarded to a network side port of the small-particle device through a switching chip and a programmable logic device FPGA (Field Programmable Gate Array field programmable gate array). This process is data interaction in the upstream direction,
step S104, based on the unique Vlan value of the small particle pipeline under the physical port of the large particle pipeline, automatically adding a virtual port expansion label Extvlan for the Ethernet service flow;
in step S104, as shown in fig. 3, a virtual ethernet tag (vlan tag) is added as a virtual port extension tag ExtVlan in the ethernet traffic by the switch chip. Preferably, the Vlan value of the small-granule pipe unique under the physical port of the large-granule pipe is automatically acquired, and is added to the ethernet traffic flow as a virtual port extension tag ExtVlan (the Vlan value corresponds to the port number of the virtual ethernet port Veth). And then sent to the programmable logic device FPGA.
It should be noted that, a plurality of virtual ethernet ports Veth are virtualized in the programmable logic device FPGA in the subsequent step, and a layer of virtual port expansion label ExtVlan is expanded in step S104 to distinguish and identify, so as to finally realize the expansion of the virtual ethernet ports Veth of the small particle pipeline.
Step S106, mapping the Ethernet service flow to a corresponding virtual Ethernet port Veth based on a virtual port expansion label Extvlan, wherein the virtual Ethernet port Veth corresponds to the small particle pipeline one by one;
in step S106, as shown in fig. 3, a plurality of virtual ethernet ports Veth are designed in the FPGA and correspond to the small particle channels. After receiving a message sent by the switching chip, analyzing the virtual port expansion tag Extvlan to obtain a Vlan value of the virtual port expansion tag Extvlan; the ethernet traffic stream is mapped to a corresponding virtual ethernet port Veth based on the Vlan value.
And stripping the virtual port expansion label Extvlan added in the Ethernet service flow to obtain the original Ethernet service flow.
It should be noted that, the hard pipeline provided by the OTN, SPN and other technologies is called a large-particle pipeline, and because the bandwidth granularity is too large (such as 2.5Gbps minimum in OTN and 5Gbps minimum in SPN), the network bearing efficiency is low because the requirements of small-bandwidth service cannot be precisely matched, so that on this basis, the small-particle pipeline bearing technologies of Mbps levels such as OSU (Optical Service Unit optical service unit), FGU (Fine Granularity Unit slice packet network fine particle unit) and the like are respectively expanded and generated. The service data of the clients are sliced and packaged into small particle pipelines, then converged into OTN and SPN large particle pipelines, and finally transmitted by the physical ports of the large particle pipelines, thereby providing a small particle bearing pipeline with low cost, refinement and hard isolation. Similar to large-particle pipeline technology, small-particle pipelines also require a corresponding two-layer port to implement the necessary two-layer ethernet processing for the traffic they carry. The virtual ethernet port Veth in step S106 is just to implement the necessary two-layer ethernet processing for the traffic carried by the small particle pipeline.
Further, the OTN (optical transport network ) has a high speed, and in OTN network transmission, clock synchronization is to be kept to ensure correct reception and analysis of data. In the mapping de-framing process AMP (Adaptive Mapping and Framing), BMP (BitTransparent apping) and GMP (GFP Mapping Protocol), etc., synchronization is very important on an end-to-end clock basis. Therefore, the clock consistency in the transmission process of the crossing board card or the device can be ensured, and the reliability and the accuracy of data transmission are ensured.
The SPN (Slicing Packet Network, slice packet network) described above inherits the functional characteristics of the PTN transmission scheme. SPNs are designed primarily for 5G transmission networks to meet the need for flexibly combined network slices in the 5G era. The network slicing refers to flexibly combining network elements of a core network to form a slicing network suitable for different service scenes. The SPN performs slice division of the transmission service at the transmission layer to realize the transmission of different services. By adopting FLEXE (Flex Ethernet) technology, physical particles with different sizes can be flexibly selected to bear service particles according to service requirements.
The IPRAN is an internet protocol based radio access network architecture aimed at providing efficient data transmission and access services for mobile communication systems. By employing an IPRAN, mobile network operators are able to implement data transmission at the radio access level using internet protocol technology. In the initial smoothed clock signal generated by the Fisher-Yates shuffle algorithm, each clock cycle corresponds to an element in the array. This initial smooth clock signal is used to read the data in the cache, ensuring that each data is read in a uniform time interval.
In addition, PTN (Packet Transport Network ) is a IP (Internet Protocol) packet transmission based network. The packet switching technology is adopted to divide data into small data packets and transmit the data packets through a network. The PTN has lower total use cost (TCO), has the traditional advantages of optical transmission, provides efficient and reliable data transmission service, and is suitable for various application scenes. PON (Passive Optical Network ) is a point-to-multipoint (P2 MP) based technology. "passive" means that the ODN (optical distribution network) does not contain any electronic components and electronic power sources, and the ODN is composed of passive components such as an optical Splitter, etc., without expensive active electronic equipment.
Step S108, the Ethernet service flow is packaged into the corresponding small particle pipeline in a slicing way through the virtual Ethernet port Veth for data interaction.
Step S108 specifically, as shown in fig. 3, the FPGA schedules the transmission sequence of the ethernet traffic flow through a plurality of buffer queues in the virtual ethernet port Veth based on the priority of the ethernet traffic flow; and encapsulating the scheduled Ethernet service flow into the corresponding small particle pipeline in a slicing way for data interaction.
It should be noted that, a plurality of queue caches are designed in the virtual ethernet port Veth, when the traffic flow exceeds the time slot configuration bandwidth of the small-granule channel, the ethernet data in the Veth can be scheduled according to priority, so as to ensure that the high-priority message (such as a protocol control message) cannot be discarded, and realize independent two-layer processing of each small-granule channel.
Through step S102 to step S108 in the embodiment of the application, virtual Ethernet ports corresponding to the small particle pipelines one by one are expanded for the Ethernet service flows based on the virtual port expansion label Extvlan, and then through the virtual Ethernet ports, the small particle pipelines realize necessary two-layer Ethernet processing of the Ethernet service flows borne by the small particle pipelines, so that the problem of how to improve the network bearing efficiency of the small bandwidth Ethernet service is solved.
In some embodiments, fig. 4 is a flowchart of steps of downlink data interaction in the ethernet data interaction method according to an embodiment of the present application, where, as shown in fig. 4, the downlink data interaction includes the following steps:
step S402, receiving the Ethernet service flow, analyzing and positioning the Ethernet service flow to obtain a small particle channel for bearing the Ethernet service flow;
specifically, in step S402, fig. 5 is a schematic flow chart of downlink data interaction in the ethernet data interaction method according to an embodiment of the present application, as shown in fig. 5, the FPGA receives an ethernet traffic data packet from a network side port of the small-particle device, analyzes and locates the data packet to obtain a corresponding small-particle pipeline, and then enters a virtual ethernet port Veth of the small-particle pipeline to perform two-layer ethernet processing.
Step S404, adding a virtual port expansion label Extvlan for the Ethernet service flow through a virtual Ethernet port Veth of the small particle pipeline;
in step S404, specifically, as shown in fig. 5, a layer of vlan tag is added to the service ethernet data packet by the virtual ethernet port Veth of the FPGA as a port expansion tag ExtVlan, and then the port expansion tag is sent to the switch chip.
Step S406, data interaction is performed based on the virtual port expansion label Extvlan and the Ethernet traffic.
In step S406, specifically, as shown in fig. 5, the switch chip parses the outermost vlan tag (i.e. ExtVlan) of the received ethernet traffic flow, and after adapting, strips off the ExtVlan to restore to the traffic ethernet packet, and then enters into corresponding forwarding in the downstream direction, and finally is sent out by the user side port of the small-particle device.
It should be noted that, when performing port-level ethernet two-layer processing (such as priority scheduling, traffic rate limiting) on service data entering a layer of hard pipes, in order not to affect the service of other hard pipes, an ethernet physical port needs to be used to interface with a layer of hard pipes. However, in applications such as OSU/FGU where there are many small particle hard pipes, there is a problem of insufficient physical ports of the ethernet.
The embodiment of the application uses a mode of adding a layer of standard Ethernet Vlan tag into the original Ethernet service flow as a port expansion tag, only a switching chip is required to provide the capability of adding a layer of Vlan tag at the forwarding position of the outlet service message, and a plurality of virtual two-layer Ethernet ports can be expanded on a limited Ethernet physical port to be in butt joint with a small particle pipeline by combining with the design of the FPGA. Because the format of the standard vlan tag is used as the port expansion tag, one Ethernet physical port can be expanded into 4095 virtual ports at most, and the technical application of a small particle pipeline can be well met.
In some embodiments, the data interaction in the uplink direction further includes:
receiving an Ethernet service flow, wherein the Ethernet service flow is carried through a small particle pipeline;
based on multiprotocol label switching mpls, automatically adding mpls labels to ethernet traffic;
mapping the Ethernet service flow to a corresponding virtual Ethernet port Veth based on the mpls label, wherein the virtual Ethernet port Veth corresponds to the small particle pipeline one by one;
and the Ethernet service flow is packaged into the corresponding small particle pipeline in a slicing way through the virtual Ethernet port Veth for data interaction.
It should be noted that, a manner of adding a layer of mpls (multiprotocol label switching) label in an original ethernet traffic stream in place of the ethernet vlan tag in the above embodiment may be used as a virtual port extension label of the ethernet traffic stream. Only the vlan tag added to the original data message forwarded between the switch chip and the FPGA in the above embodiment is replaced by an mpls tag, that is, the sender adds a layer of mpls tag in the original ethernet message, and the receiver parses the outermost mpls tag to identify the corresponding extended virtual port. The mpls label values used are allocated in small particle pipes (but cannot be the same as the mpls labels that might be used in an ethernet traffic stream).
It should be noted that the steps illustrated in the above-described flow or flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow diagrams, in some cases, the steps illustrated or described may be performed in an order other than that illustrated herein.
