Description

F5G terminal VLAN aggregation method, system, device and storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a system, an apparatus, and a storage medium for F5G terminal VLAN aggregation.

Background

F5G (The 5th generational fixed Network), i.e. fifth generation fixed Network, in The F5G era, a physical fiber (fiber) Network is moved to an all-optical service Network, which includes two major parts, an all-optical access Network and an all-optical transport Network. A VLAN, also known as a virtual local area network, is a group of logical users and devices that are used to combine terminals distributed in different geographical locations into a logical network according to communication needs. The terminals in the same logic network can communicate with each other, and the terminals in different logic networks can not communicate directly.

In practical applications, terminals under different VLANs may generate communication requirements. In the prior art, VLAN aggregation is usually adopted for solving the problem, specifically, after uplink data transmitted by a downlink interface is received by an uplink interface, a VLAN of the downlink interface is converted into a VLAN of the uplink interface, so that a terminal corresponding to the downlink interface and an upper computer corresponding to the uplink interface are located under the same VLAN; and after the downlink interface receives the downlink data transmitted by the uplink interface, the VLAN of the uplink interface is converted into the VLAN of the downlink interface, so that the upper computer corresponding to the uplink interface and the terminal are positioned under the same VLAN. The mutual conversion process between multiple VLANs and one VLAN is VLAN aggregation.

However, since the number of the downlink interfaces is large, when the uplink interface is converted into the VLAN of the downlink interface, it is necessary to know which VLAN of the downlink interface is converted. The existing solution is to duplicate the broadcast, i.e. transmit the downlink data to all downlink interfaces, and after a certain terminal feeds back that it is the receiver of the downlink data, convert the VLAN of the uplink interface into the VLAN of the downlink interface corresponding to the terminal. But the manner of duplicate broadcasting reduces the transmission efficiency of network information.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to be limiting of the invention.

When the number of the downlink ports is large, after the current port receives the downlink data, the current port cannot know which VLAN the VLAN of the current port is converted into, and only receives feedback of the downlink port in a manner of copying the downlink data and broadcasting again, so that which downlink port corresponds to the downlink data is known. However, the broadcast duplication reduces the transmission efficiency of network information and also reduces the efficiency of VLAN aggregation. Based on this, the embodiment of the present application discloses a F5G terminal VLAN aggregation method, where a VLAN of a current port and a VLAN of a downstream port are both configured in a bridge, and the bridge supports a VLAN aggregation function, and specifically, the bridge is an 802.1Q-attribute bridge, and supports not only the VLAN aggregation function but also the VLAN. As shown in fig. 1, the method includes:

s101, after receiving the downlink data, extracting the destination address data from the downlink data.

The downlink data refers to data transmitted to the lower computer by the upper computer. The destination address data refers to an MAC address of a destination terminal of the downlink data, wherein the destination terminal refers to a transmission destination terminal of the downlink data; for example, if terminal a transmits data to terminal B, terminal B is the destination terminal, and routers, switches, and the like that pass through the destination terminal do not belong to the destination terminal. Before the terminal sends data to the outside, the MAC address of the destination terminal is obtained, and based on this, the downlink data carries the MAC address of the destination terminal, that is, destination address data. Therefore, the destination address data can be found from the downlink data according to the destination address data label or position, and then extracted and obtained.

S102, inquiring whether record address data matched with the destination address data are stored in the aggregation table.

The aggregation table stores record address data, which is, in an embodiment, the MAC address of the terminal. If the same record address data as the destination address data exists in the aggregation table, judging that the record address data is matched with the destination address data; if the aggregation table does not have the same recording address data as the destination address data, the determination is made as a mismatch.

In another embodiment, the address data is recorded as a MAC address set or a MAC address field, and if the destination address data is located in the MAC address set or the MAC address field, it is determined as matching, otherwise, it is determined as not matching.

And if the aggregation table stores the record address data matched with the destination address data, calling the downlink port identification corresponding to the record address data in the aggregation table.

That is, the aggregation table stores a plurality of recording address data, and each recording address data corresponds to a downlink port identifier. It should be noted that, before the downlink terminal sends data to the outside, a data packet for obtaining the MAC address of the destination terminal is actively uploaded, and the downlink port corresponding to the downlink terminal, the VLAN of the downlink port, and the MAC address of the downlink terminal can be obtained through the data packet, so as to obtain the downlink address data of the downlink port and the corresponding downlink port identifier. And storing the downlink address data and the downlink port identification of each downlink port in an aggregation table.

In an embodiment, the downlink port identifier is a name of the downlink port, for example, there are 3 downlink ports corresponding to the current port, and the names of the downlink ports are, in order, port a, port B, and port C. The port A corresponds to a terminal a, and the MAC address of the terminal a is 1; the port B corresponds to a terminal B, and the MAC address of the terminal B is 2; the port C corresponds to the terminal C, and the MAC address of the terminal C is 3. When the destination address data in the agile star data is 3, the record address data with 3 stored in the aggregation table is queried, and at this time, the downlink port identifier of "port C" can be obtained, so that which port corresponds to the downlink data is can be known, the port is known, and the VLAN of the port can be known.

In another embodiment, the downstream port identification is the name of the downstream port's VLAN. For example, the VLAN names of ports A, B and C are VLAN1, VLAN2, and VLAN3, in that order. After obtaining the VLAN name, it can be known to which VLAN the VLAN of the current port needs to be converted.

S103, converting the current VLAN of the current port into the downlink VLAN of the downlink port corresponding to the downlink port identification so as to complete VLAN aggregation.

Setting an aggregation table, and storing the MAC address of the terminal corresponding to the downlink port in the aggregation table, and storing the downlink port identifier. Therefore, after the destination address data of the downlink data is obtained, the corresponding downlink port identifier can be searched in the aggregation table according to the destination address data. After the downstream port identification is obtained, the current VLAN can be converted into the downstream VLAN corresponding to the downstream port identification, and the broadcast is not required to be copied, so that the transmission efficiency of network information and the efficiency of VLAN aggregation are improved, and network resources are saved. In an embodiment, the IP address corresponding to the current VLAN is converted into the IP address corresponding to the downlink VLAN, that is, it is determined that the current VLAN is converted into the downlink VLAN.

In another embodiment of the present invention, for further limitation and explanation, when the aggregation table does not store the record address data matching the destination address data, the method further includes:

s201, inquiring all downlink ports in the same subnet area with the destination address data.

In one embodiment, when the bridge is connected to the port, the downstream port connected to the bridge is recorded, so that the downstream port in the same subnet area can be found in the port connection data of the bridge.

In another embodiment, the ports connected to the network bridge are all recorded in the document, which network bridges are connected to the current port are inquired first, and then the destination address data in the downlink data is used to find the network bridge connected to the corresponding downlink terminal, so as to lock the network bridge connected together, and then all the downlink ports under the network bridge are inquired in the recorded document.

S202, acquiring downlink address data of all downlink ports and corresponding downlink port identifications.

S203, adding the downlink address data and the corresponding downlink port identification into the aggregation table to convert the downlink address data into the recorded address data.

Because the downlink address data and the downlink port identifier are obtained in the aggregation table when the downlink terminal actively queries the MAC address of the destination terminal, for the downlink terminal which has not actively transmitted data to the outside, the aggregation table does not store the corresponding downlink address data and the corresponding recorded address data. Therefore, the downlink address data and the downlink port identification of the downlink port are actively acquired so as to perfect the data in the aggregation table.

The method is favorable for obtaining the downlink port identification corresponding to the downlink data by actively obtaining the downlink address data and the downlink port identification, thereby converting the current VLAN of the current port into the downlink VLAN, completing the transmission of the downlink data aggregated by the VLAN as soon as possible and improving the transmission efficiency of network information. In addition, the downstream port identifier is added to the aggregation table, which is helpful for ensuring the transmission efficiency of subsequent downstream data.

In another embodiment of the present invention, for further limitation and description, the step of acquiring the downlink address data and the corresponding downlink port identifier of all the downlink ports includes:

s301, address requests are sent to all downlink ports.

In one embodiment, the address request is an APR request.

And S302, receiving response data fed back by the downlink port based on the address request.

It should be noted that, since the address request is sent, the downlink port returns downlink address data, that is, the response data includes the downlink address data.

S303, extracting the downlink address data of the downlink port and the corresponding downlink port identification from the response data.

The response data also includes a downlink port identifier. On one hand, compared with the method of transmitting downlink data, the address request occupies less network resources, and has higher transmission efficiency, thereby being beneficial to ensuring the efficiency of VLAN aggregation; on the other hand, the data volume carried in the data returned based on the APR request is small, so that the transmission efficiency is convenient to ensure.

In another embodiment of the present invention, for further definition and explanation, after the step of sending the address request to all downstream ports, the method further comprises:

and deleting the corresponding downlink data.

Since the record address data corresponding to the destination address data is not matched in the aggregation table, an address request needs to be transmitted to the downstream port. But the downlink data is deleted at the moment, so that on one hand, network resources occupied by the downlink data are reduced; on the other hand, the replication and broadcasting of the downlink data are avoided, so that the network transmission efficiency is reduced.

In another embodiment of the present invention, for further definition and illustration, the method further comprises:

s401, when a data packet uploaded by a newly added downlink port is received, extracting downlink address data of the newly added downlink port and a corresponding downlink port identifier from the data packet.

S402, adding the downlink address data and the corresponding downlink port identification into an aggregation table so as to convert the downlink low-speed data into the recorded address data.

Because each downlink terminal needs to upload an output packet before transmitting data outwards, the MAC address of the destination terminal is required. Therefore, when a newly added downlink terminal uploads a data packet by using a downlink port, downlink address data and a downlink port identifier of the downlink port are actively stored in the aggregation table, the phenomenon that the downlink address data are actively acquired due to insufficient data records in the aggregation table in the later period is reduced, and the transmission efficiency of network information and the efficiency of VLAN aggregation are favorably ensured.

s501, after receiving the uplink data, extracting a preset conversion mapping relation.

The uplink data refers to data transmitted from the lower computer to the upper computer, that is, data transmitted from the downlink terminal to the uplink terminal. In one embodiment, the conversion mapping relationship is pre-stored at the designated position, and when the conversion mapping relationship needs to be queried, the conversion mapping relationship is extracted from the designated position according to the preset position information. Wherein, the conversion mapping relation refers to the mapping relation for converting the current VLAN into the uplink VLAN.

It should be noted that, for the upstream VLAN, there are a plurality of current ports at the same level as the current VLAN, but for the current port, there is only one upstream port. Therefore, no matter which current VLAN the current port corresponds to, the final conversion result is only one, i.e., the upstream VLAN. For example, the downstream VLANs include a downstream VLAN1, a downstream VLAN2, and a downstream VLAN3, and only one corresponding upstream VLAN is an upstream VLAN 1. The mapping relationship is converted into the downstream VLAN1 converted into the upstream VLAN1, the downstream VLAN2 converted into the upstream VLAN1, and the downstream VLAN3 converted into the upstream VLAN 1.

S502, converting the current VLAN of the current port into the uplink VALN of the corresponding uplink port based on the conversion mapping relation.

The VLAN aggregation is performed during uplink data transmission by using the preset conversion mapping relation without executing excessive steps, so that the number of information transmitted for VLAN aggregation in network information is reduced, the occupation of a network is reduced, and the efficiency of VALN aggregation and network information transmission of other ports is favorably ensured.

In another embodiment of the present invention, for further limitation and description, the step of converting the current VLAN of the current port into the upstream VLAN of the corresponding upstream port based on the conversion mapping relationship includes:

s601, obtaining the uplink port identification in the conversion mapping relation.

Since there is only one upstream port for the current port, the upstream port identifier is pre-stored in the translation mapping relationship. Can be directly obtained when needed, and is convenient and quick.

S602, converting the current VLAN into an uplink VLAN corresponding to the uplink port identification.

The corresponding uplink VLAN can be known through the uplink port identification, so that VLAN aggregation can be directly carried out, the VLAN aggregation efficiency and the network information transmission efficiency are ensured, and the occupation of network resources is reduced.

After receiving the downlink data, obtaining destination address data from the downlink data, and searching a corresponding downlink port identifier in the aggregation table according to the destination address data. The downlink port identification can be used for knowing which downlink VLAN in all downlink ports the current VLAN is to be converted into, broadcast copying is not needed, and VLAN aggregation efficiency is improved. When a downlink interface transmits a data packet to a current port for the first time, downlink address data and a downlink port identifier of the downlink interface are obtained from the data packet, and the downlink address data and the downlink port identifier are maintained in an aggregation table, so that the method is convenient to use when the VLAN is aggregated. In addition, when the downlink port identifier is not found, the downlink port identifier of each downlink port is obtained in a mode of transmitting address requests to all downlink ports, and compared with a mode of copying and broadcasting downlink data, network resources are saved.

The embodiment of the present application further discloses an F5G terminal VLAN aggregation system, referring to fig. 2, the system includes an obtaining module 1, configured to extract destination address data from downlink data after the downlink data is received;

the query module 2 is configured to query whether record address data matching the destination address data is stored in an aggregation table, and if so, retrieve a downlink port identifier corresponding to the record address data in the aggregation table;

and the aggregation module 3 is used for converting the current VLAN of the current port into a downlink VLAN of the downlink port corresponding to the downlink port identifier so as to complete VLAN aggregation.

Preferably, when the record address data matching the destination address data is not stored in the aggregation table, the query module 2 includes a query unit, configured to query all the downlink ports in the same subnet area as the destination address data;
