Description
Technical Field
The present disclosure relates to the field of communications of intelligent automobiles, and in particular, to a network management method, device, apparatus, and storage medium.
Background
The development of the intellectualization and networking of automobiles requires high-performance computing capability, flexible software functions and quick network communication capability, which promotes a new generation of electronic and electric architecture with high-speed communication capability based on a vehicle-mounted Ethernet, such as a network topology diagram shown in fig. 1, wherein the architecture is centered on a central computing unit, a plurality of regional computing units are connected through the Ethernet, data packet forwarding is carried out among the regional computing units through the central computing unit to realize communication, and the regional computing units are communicated with an external network through the central computing unit uniformly.
Adaptive AUTOSAR (AP) is used as a standardized middleware for supporting high-performance ECU of a new generation of electronic and electric architecture, and is designed and developed according to the principle of service oriented architecture design (SOA). As shown in fig. 1, service-oriented communication is performed between a central computing unit and an area computing unit on which an AP system is installed based on SOMEIP or DDS, if one area computing unit transmits a SOMEIP packet or a socket packet to the other area computing unit, after the packet arrives at the central computing unit, it does not know to which area computing unit the packet is to be forwarded, and similarly, if the area computing unit is to transmit data to an external network, the central computing unit does not know to which network the packet is to be forwarded.
There are 2 kinds of improvement schemes for the above problems:
1. by adding a switch in the central computing unit, the target forwarding of the communication data packet between the regional computing units is realized; however, adding a switch causes an increase in cost, and when the area computing unit is to communicate with an external network through the central computing unit, the switch still cannot forward the data packet to the target network.
2. Upgrading the central computing unit to have a gateway function so as to solve the problem that the regional computing unit communicates with the external network through the central computing unit; however, the cost of the whole vehicle can be greatly increased, and meanwhile, because the network function needs are various and different vehicle factories need different, the gateway needs to be customized, so that the cost is further increased.

Therefore, it is needed to solve the problem that how to forward the communication data packet to the destination when each area computing unit performs network data packet communication through the central computing unit after each computing unit in the new generation of electronic and electric architecture is installed with the AP system without increasing the cost, and especially how to forward the data packet to the corresponding network channel when the central computing unit communicates with the external network.

In this embodiment of the present application, the network management module NM of the central computing unit of the AP system is responsible for network management of the AP system platform, and the working modes thereof are as follows:
a Bus-Sleep Mode and a low power consumption Mode, wherein the Mode does not send network management messages or receive application messages;

Referring to fig. 3, fig. 3 is a schematic diagram of a new generation of electronic and electric network of an automobile according to an embodiment of the present application, where the central computing unit in fig. 3 includes eth0, eth1, eth2, eth3 4 network interfaces, and the 4 network interfaces are respectively used to connect with a regional computing unit; it should be noted that, the number of network interfaces and the number of area computing units in fig. 2 are only schematic, the number of area computing units in the actual architecture can be increased according to actual requirements, and the area computing units can be divided into pieces in the physical space of the automobile; in addition to the communication between the area computing units and the central computing unit, the communication between the 4 area computing units needs to be forwarded by the central computing unit. The central computing unit is responsible for task scheduling of each zone controller, and the high-power task of the zone control unit is responsible for completion by the central computing unit. Each area computing unit can be mutually backup of the other side, backup data are required to be transmitted to the other side, the area computing units are connected with various ECU control units, and data received by the different area computing units can be information data such as outer lamps, wipers, locks, keys, windows and electric tail doors, and can also be information data such as energy consumption management, gear switching, diagnosis information and various sensor data. In addition, the central computing unit further comprises network interfaces APN1 and APN2 which are respectively used for being connected with an external public network and a private network, so that network data of the external network can reach the inside of the vehicle.
Specifically, when the NM module of the central computing unit is in the network mode, a communication address network segment is configured for each network interface (eth 0, eth1, eth2, eth3, APN1, APN 2), for example, the communication address network segment corresponding to the interface eth0 is 192.168.1.0/24, the communication address network segment corresponding to the interface eth1 is 192.168.2.0/24, the communication address network segment corresponding to the interface eth2 is 192.168.3.0/24, the communication address network segment corresponding to the interface eth3 is 192.168.4.0/24, the communication address network segment corresponding to the interface APN1 is 103.49.10.0/24, the communication address network segment corresponding to the interface APN2 is 103.49.11.0/24, and a static routing table corresponding to each network interface is created; taking the static routing table of interface eth0 as an example, it includes the following information:
192.168.1.0/24dev eth0…src 192.168.1.1
default via 192.168.1.1dev eth0
wherein, the field src tells the kernel that the selected source address is 192.168.1.1 when the data is routed outwards using the region computation unit; default is the default route and if the IP of the target host is not found, it is sent to the 192.168.1.1 address through the eth0 port.
S203: creating a routing rule; the routing rule includes a mapping relationship between each communication address network segment and a static routing table.
In the embodiment of the application, the AP respectively builds a static routing table of each network interface and creates a routing rule based on a Linux kernel by adopting an ip route/rule command of Linux. The routing rules are global to the central computing unit in kernel space.
In an alternative embodiment for creating routing rules, the method comprises:
and establishing a mapping relation between the source communication address network segment and the static routing table based on the communication address network segment of the network interface for transmitting data.
In another alternative embodiment for creating a routing rule, the method includes:
and establishing a mapping relation between the target communication address network segment and the static routing table based on the communication address network segment of the network interface for receiving the data.
Further, in the process of creating the routing rule, the method may further include: and configuring routing priority for the communication address network segment corresponding to each network interface. Thus, for data with high real-time requirements, the data is preferentially routed and forwarded.
S205: when data is received through any network interface, a corresponding target static routing table is determined from the mapping relation according to communication address information carried by the data; the target static routing table is used for realizing data transmission; the communication address information refers to address information of each subnet in the communication address network segment.
In the embodiment of the application, when the central computing unit receives data through any network interface, a corresponding target static routing table is determined from the mapping relation according to the communication address information carried by the data; the communication address information carried by the data can be the address information of the target subnet or the address information of the source subnet.
In an optional implementation manner, when the communication address information is address information of a target subnet carried by data, determining, according to the communication address information carried by the data, a corresponding target static routing table from the mapping relationship may include:
determining a target communication address network segment according to the address information of the target subnet carried by the data;
and determining a corresponding target static routing table from the mapping relation according to the target communication address network segment.
In another optional implementation manner, when the communication address information is address information of a source subnet carried by data, determining, according to the communication address information carried by the data, a corresponding target static routing table from the mapping relationship may include:
determining a source communication address network segment according to address information of a source subnet carried by data;
and determining a corresponding target static routing table from the mapping relation according to the source communication address network segment.
Specifically, based on the architecture shown in fig. 3, the following routing rules may be created:
100:to 192.168.1.0/24 table eth0
101:to 192.168.2.0/24 table eth1
102:to 192.168.3.0/24 table eth2
103:to 192.168.4.0/24 table eth3
104:to 103.49.10.0/24 table apn1
105:to 103.49.11.0/24 table apn2
the numbers to the left of the colon above represent priorities, and the routing rules are interpreted as:
routing the data packet to the computing unit of the area where the 192.168.1.0 network segment is located by using the eth0 routing table;
routing the data packet to the computing unit of the area where the 192.168.2.0 network segment is located by using the eth1 routing table;
routing the data packet to the area computing unit where the 192.168.3.0 network segment is located by using the eth2 routing table;
routing the data packet to the area computing unit where the 192.168.4.0 network segment is located by using the eth3 routing table;
the data packet destined for 103.49.10.0 network segment (public network) is destined for external network, and the routing table route is apn;
packets destined for the 103.49.11.0 segment (private network) are also routed to the foreign network, routing table apn.
In practical application, the routing rule is flexible to use, and the rule condition can be flexibly created according to practical needs by taking destination communication address information or source communication address information and the like as judgment conditions.
In an alternative embodiment, since the AP system is based on a Linux system kernel, the Linux system kernel prohibits packet forwarding by default, and thus the method may further include:
the routing function is started by configuring the kernel parameters in any mode of a sysctl instruction, modifying the mapping file of the kernel parameters and modifying the configuration file.
Specifically, the-w parameter of the sysctl command can modify the kernel parameter of Linux in real time, and the following command is used: sysctl-w net.ipv4.ip_forward=1, i.e. routing forwarding can be turned on.
In summary, the network management method provided by the embodiment of the application can make up for the defect of the existing Adaptive AUTOSAR NM module function on the premise of not increasing the cost, and can solve the problem of network data packet routing among all computing units by adding the network configuration management and policy route generation functions, so that the central computing unit can forward the data packet to reach the designated network.
