But mirroring port 1 cannot mirror port data on other switches. If the data of a plurality of devices in the whole system needs to be backed up, the switches connected with the devices need a mirror port, and the data backup device also needs to be provided with a corresponding number of interfaces to connect all the mirror ports. If the distance between the switches is long, the connection between each mirror image port and the data backup device is also quite difficult, which is extremely inconvenient and increases the difficulty of system deployment.
Secondly, the mirroring principle is to mirror the port, for example, mirroring the data of the port 1, the mirroring port will copy all the data of the port 1, and it is not possible to select which specific data in the port 1 needs mirroring, and the data that does not need to be backed up will also be mirrored out, and a data backup device is required to perform data cleaning, which results in waste of resources for calculation, storage, and screening.

Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
Referring to fig. 1, 2 and 3, an embodiment of the present application provides a power distribution network domain type fast protection network data mirroring system, including: the system comprises a main mirror image switch and a plurality of sub mirror image switches;
as shown in fig. 2, the main mirror switch in this embodiment is composed of two network side interfaces a/B, 1 or more than 1 device interface, a mirror port, a first data forwarding component, a first mirror decision component, a mirror configuration component, and a mirror decapsulation component.
A network side interface: interfaces interconnecting the switches;
and (3) equipment interface: an interface for connecting the protection device and other Ethernet equipment;
mirror image interface: an interface that transmits mirrored data to the data backup apparatus (the mirrored interface does not receive data);
wherein, the primary mirroring switch comprises:
a first mirror configuration component to:
generating a mirror image address table containing a plurality of groups of destination MAC addresses and source MAC addresses, and sending the mirror image address table to a first mirror image decision component;
it should be noted that the ethernet data frame includes a destination MAC address and a source MAC address, and communication data between any two protection devices that need to be mirrored in the entire system is configured in a mirror MAC configuration component to generate a mirror address table with two MACs as a group. E.g., MAC 1< - > MAC 2; MAC 1< - > MAC 3; MAC N < - > MAC 2, and the like. A group of two MACs in the mirror address table corresponds to a destination MAC address and a source MAC address in an ethernet data frame. The mirror MAC configuration component passes the generated mirror address table to the first mirror decision component.
A first mirroring decision component to:
generating a mirror image rule message according to the mirror image address table and the IP of the main mirror image switch;
judging whether the Ethernet message forwarded by the first data forwarding component needs mirroring, if so, sending the Ethernet message to a protection device connected with a primary mirroring switch, and meanwhile, directly sending the Ethernet message to a data backup device connected with the primary mirroring switch after copying the Ethernet message, otherwise, sending the Ethernet message to the protection device connected with the primary mirroring switch;
receiving an Ethernet message of a protection device connected with a primary mirroring switch, and sending the Ethernet message to a first data forwarding component;
it should be noted that the first mirroring decision component has three functions, which are 1) generating a mirroring rule message, 2) determining whether the ethernet message needs mirroring, and 3) receiving the ethernet message of the protection device connected thereto.
Specifically, the method comprises the following steps:
1) The first mirroring decision component of the main mirroring switch generates a mirroring rule message, and the mirroring rule message is an Ethernet broadcast message of a destination address FF: FF: FF: FF: FF. The mirror image rule message contains information of all mirror image address tables and the IP address of the main mirror image switch, and the first data forwarding component sends the information to other mirror image switches from the network side interface.
2) When the first mirroring decision module receives the ethernet message forwarded by the first data forwarding module, the first mirroring decision module compares an MAC address forwarding table (a protection device accessed to an equipment interface of the switch, and the switch can learn MAC) preset by a mirroring switch with the mirroring address table to determine whether a destination MAC address and a source MAC address of the ethernet message sent by the first data forwarding module need mirroring. If the mirror image address table does not have the MAC information of the Ethernet message, the first mirror image decision component directly sends the Ethernet message to a protection device connected with the first mirror image decision component through an equipment interface (all switches for copying communication data to form mirror image messages are necessarily switches accessed by destination MAC of original data). If the mirror image address table matches the MAC information of the data and the destination MAC of the Ethernet message is the MAC of the protection device of the equipment interface, the Ethernet message is sent from the equipment interface to the protection device connected with the equipment interface, and the whole Ethernet message is copied, passes through the first mirror image decapsulation component and is sent from the mirror image port to the data backup device.
3) And receiving an Ethernet message of the protection device connected with the primary mirroring switch (the protection device connected with the primary mirroring switch can generate the Ethernet message), and sending the Ethernet message to the first data forwarding component (so that the first data forwarding component forwards the Ethernet message to other mirroring switches).
A first data forwarding component to:
sending a mirror rule message to a sub-mirror switch;
receiving Ethernet messages forwarded by other mirror image switches, and sending the Ethernet messages to a first mirror image decision component according to the target MAC of the Ethernet messages, or forwarding the Ethernet messages to other mirror image switches;
receiving an Ethernet message forwarded by a first mirror image decision component, and forwarding the Ethernet message to other mirror image switches according to an MAC address forwarding table;
it should be noted that the first data forwarding component has three functions, namely 1) sending the mirror image rule message to other mirror image switches, and 2) receiving or forwarding the ethernet messages of other mirror image switches; 3) Receiving and forwarding the Ethernet message forwarded by the first mirroring decision component (of the self device).
Specifically, the method comprises the following steps:
1) After the first data forwarding component receives the mirror image rule message of the first mirror image decision component, the data forwarding component sends the mirror image rule message to other mirror image switches from the network side interface A/B.
2) After receiving the ethernet message sent by other image switches from a network side interface, the first data forwarding component judges whether the destination MAC of the ethernet message is the access device (the protection device connected with the primary image switch) of its own device interface according to the preset MAC address forwarding table, and forwards the ethernet message to the first image decision component if the destination MAC is itself. And if the destination is not the mirror image switch, forwarding the Ethernet message to other mirror image switches from another network side interface.
3) And after receiving the Ethernet message forwarded by the first mirroring decision component, the first data forwarding component forwards the Ethernet message to other mirroring switches according to an MAC address forwarding table preset by the first primary mirroring switch.
A mirror decapsulation component to:
and decapsulating the mirror image data messages forwarded by other mirror image switches into original Ethernet messages, and sending the original Ethernet messages to the data backup device.
It should be noted that the mirror decapsulation component of the master mirror switch does not perform encapsulation of the mirror rule packet, but only has a decapsulation function. When the mirror image data is data of an equipment interface of the main mirror image switch (an Ethernet message generated by a protection device connected with the main mirror image switch), the data entering the mirror image decapsulation component is an original Ethernet message, is directly transmitted through (through the mirror image decapsulation component), and is sent to the data backup device from the mirror image port. When the mirror image data is the mirror image data message encapsulated by other mirror image switches, the mirror image decapsulation component decapsulates the mirror image data message, restores the mirror image data message to the original Ethernet message, and sends the original Ethernet message to the data backup device from the mirror image port.
As shown in fig. 3, the sub-mirror switch in this embodiment is composed of two network side interfaces a/B, 1 or more than 1 device interface, a second data forwarding component, a second mirror decision component, and a mirror encapsulation component.
A network side interface: interfaces interconnecting the switches;
and (3) equipment interface: an interface for connecting the protection device and other Ethernet equipment;
the sub-mirror switch includes:
a second data forwarding component to:
receiving a mirror image rule message, sending the mirror image rule message to a second mirror image decision component, and forwarding the mirror image rule message to other mirror image switches;
receiving Ethernet messages forwarded by other mirror image switches, and sending the Ethernet messages to a second mirror image decision component according to the destination MAC of the Ethernet messages, or forwarding the Ethernet messages to other mirror image switches;
receiving a mirror image data message sent by a mirror image packaging assembly and sending the mirror image data message to a main mirror image switch;
it should be noted that the second data forwarding component has three functions, which are 1) receiving and forwarding the mirror rule packet sent by the primary mirror image switch, 2) receiving or forwarding the ethernet packet sent by another mirror image switch, and 3) sending the encapsulated mirror image data packet to the primary mirror image switch.
Specifically, the method comprises the following steps:
1) After receiving the mirror image rule message of the main switch from one network side interface, the second data forwarding component forwards the mirror image rule message to the second mirror image decision component, and simultaneously forwards the mirror image rule message from the other network side interface, so that the other mirror image switches acquire the mirror image rule message;
2) After receiving the ethernet message sent by other mirror image switches from a network side interface, the second data forwarding component judges whether the destination MAC of the ethernet message is the access device (connected with the protection device) of its own device interface according to a preset MAC address forwarding table, and forwards the ethernet message to the second mirror image decision component if the destination is itself. If the destination is not the self, the message is forwarded to other mirror image switches from another network side interface;
3) And after receiving the mirror image UDP message (mirror image data message) forwarded by the mirror image packaging component, the second data forwarding component sends the mirror image UDP message to the main mirror image switch from the network side interface according to a preset MAC address forwarding table.
A second mirroring decision component to:
converting the mirror rule message into a mirror address table and an IP of a main mirror switch, and sending the mirror address table and the IP to a mirror packaging assembly;
receiving an Ethernet message sent by a second data forwarding component, judging whether the Ethernet message needs mirroring or not, if so, sending the Ethernet message to a protection device connected with a sub-mirroring switch, and meanwhile, copying an Ethernet broadcast message and then sending the Ethernet message to a mirroring packaging component, otherwise, sending the Ethernet message to the protection device connected with the sub-mirroring switch;
it should be noted that the second mirroring decision component has two functions, which are 1) to convert the mirroring rule packet sent by the primary mirroring switch, and 2) to determine whether the ethernet packet sent by the other mirroring switches needs to be mirrored.
Specifically, the method comprises the following steps:
1) Receiving a mirror image rule message sent by a main mirror image switch from a network side interface, storing mirror image rule information in the mirror image rule message, and generating a mirror image address table; and simultaneously, the IP and MAC address information of the master switch is sent to the mirror image packaging component for storage.
2) When the mirror image decision component receives the Ethernet message of the protection device connected with the sub mirror image switch, the mirror image address table is used for comparing an MAC address forwarding table (the protection device is accessed to the switch equipment interface, and the switch can learn MAC) preset by the sub mirror image switch, and whether the destination MAC address and the source MAC address of the Ethernet message sent by the second data forwarding component need to be mirrored or not is judged. If the mirror image address table does not have the MAC information of the Ethernet message, the second mirror image decision component directly sends the Ethernet message to the protection device through the equipment interface. If the mirror image address table is matched with the MAC information of the Ethernet message and the target MAC of the Ethernet message is the MAC of the protection device of the equipment interface, the Ethernet message is sent from the equipment interface to the protection device connected with the equipment interface, the whole Ethernet message is copied, the Ethernet message is transferred to a mirror image packaging assembly, and the mirror image message is packaged.
