As shown in fig. 1, the present application is mainly applied to a high-end MCU which runs under an ethernet architecture of a whole automobile and uses Linux as a kernel (the kernel version is not lower than 2.1). Under the novel automobile electronic and electrical architecture based on the Ethernet, a central computing unit is connected with various regional computing units through the Ethernet, a high-performance central computing unit carrying an AP system is connected with the regional computing units through the Ethernet, and the central computing unit is responsible for forwarding all network data packets passing through the central computing unit to a target network or a target network port, so that policy routing planning needs to be carried out on the data packets to realize data packet shunting.
According to the network management method provided by the embodiment of the application, on the premise of not increasing the cost, the defect of the Adaptive AUTOSAR NM module function can be overcome, the network data packet routing problem among the computing units can be solved by adding the network configuration management and policy routing generation functions, and the central computing unit can forward the data packet to a specified network (a public network or a private network).
A specific embodiment of a network management method according to the present application is described below, and fig. 2 is a schematic flow chart of a network management method according to the embodiment of the present application, and the present specification provides the method operation steps according to the embodiment or the flow chart, but more or less operation steps may be included based on conventional or non-creative labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. In practice, the system or server product may be implemented in a sequential or parallel manner (e.g., parallel processor or multi-threaded environment) according to the embodiments or methods shown in the figures. Specifically, as shown in fig. 2, the method may include:
s201: when the network management module of the central computing unit is in a network mode, configuring a corresponding communication address network segment and a static routing table for each network interface in a plurality of network interfaces; the network interfaces are used for connecting an external network and each internal area computing unit.
In the embodiment of the present application, the network management module NM of the central computing unit carrying the AP system is responsible for network management of the AP system platform, and its working modes include three types:
a Bus-Sleep Mode dormant Mode and a low power consumption Mode, wherein in the Mode, no network management message is sent and no application message is sent and received;
a Prepare Bus-Sleep Mode pre-Sleep Mode, which indicates a previous standby state entering the Sleep Mode, and in the Mode, network management message frames and application messages are not sent generally, and all nodes empty sending caches before entering the Bus-Sleep Mode;
the Network Mode allows each ECU in the vehicle to carry out normal communication, namely, Network management message frames can be received and transmitted, and application messages can be received and transmitted;
as can be seen from the above working mode of the NM module, the data transmission states in different modes only need to perform routing planning and add corresponding routing policies to data in the data transmission mode, that is, in the network mode, and the network card can also be configured and managed as needed in other modes.
Based on this, in the embodiment of the present application, when the network management module of the central computing unit is in the network mode, a corresponding communication address network segment and a static routing table are configured for each network interface in the plurality of network interfaces; the network interfaces are used for connecting an external network and each internal area computing unit.
Referring to fig. 3, fig. 3 is a schematic diagram of a new generation automotive electronic-electrical network topology according to an embodiment of the present disclosure, in which the central computing unit in fig. 3 includes eth0, eth1, eth2, and eth 34 network interfaces, and 4 network interfaces are respectively used to connect to an area computing unit; it should be noted that the number of the network interfaces and the number of the area calculating units in fig. 2 are only schematic, the number of the area calculating units in the actual architecture may be increased according to the actual requirement, and the area calculating units may be divided into pieces in the physical space of the automobile; in addition to the communication between the regional computing units and the central computing unit, the communication between the 4 regional 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-computation-power tasks of the zone control units are completed by the central computing unit. Each regional computing unit can be used for mutual backup of the other side, backup data is transmitted to the other side as required, various ECU control units are connected with the regional computing units, and the data received by the different regional computing units can be information data such as external lamps, windscreen wipers, locks, keys, car windows, electric tail gates and the like, and can also be information data such as energy consumption management, gear switching, diagnostic information, various sensor data and the like. In addition, the central computing unit further comprises network interfaces APN1 and APN2, which are respectively used for connecting 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 (eth0, eth1, eth2, eth3, APN1, APN2), for example, the communication address network segment corresponding to interface eth0 is 192.168.1.0/24, the communication address network segment corresponding to interface eth1 is 192.168.2.0/24, the communication address network segment corresponding to interface eth2 is 192.168.3.0/24, the communication address network segment corresponding to interface eth3 is 192.168.4.0/24, the communication network segment corresponding to interface APN1 is 103.49.10.0/24, the communication address network segment corresponding to 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 the 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 routing data out using the local compute unit; default is the default route, and if the IP of the target host is not found, the default route is sent to the 192.168.1.1 address through the eth0 port.
S203: creating a routing rule; the routing rule comprises the mapping relation between each communication address network segment and the static routing table.
In the embodiment of the application, the AP respectively constructs the static routing tables of each network interface and establishes the routing rules by adopting an ip route/rule command of Linux based on a Linux kernel. The routing rules are global to the central computing unit in kernel space.
In an alternative embodiment, the method for creating the routing rule includes:
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 sending data.
Another optional implementation of creating a routing rule 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 the routing priority for the communication address network segment corresponding to each network interface. In this way, data with high real-time requirements is preferentially routed and transferred.
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 under 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 communication address information carried by the data; the communication address information carried by the data may be address information of the target subnet, and may also be 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, and the determining a corresponding target static routing table from the mapping relationship according to the communication address information carried by the data may include:
determining a target communication address network segment according to address information of a target subnet carried by 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, when the communication address information is address information of a source subnet carried by data, and the determining a corresponding target static routing table from the mapping relationship according to the communication address information carried by the data 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 number to the left of the colon represents priority, and the routing rule is interpreted as:
the data packet to the area calculation unit where the 192.168.1.0 network segment is located goes through the eth0 routing table route;
the data packet to the area calculation unit where the 192.168.2.0 network segment is located goes through the eth1 routing table route;
the data packet going to the calculation unit of the area where the 192.168.3.0 network segment is located goes through the eth2 routing table;
the data packet going to the calculation unit of the area where the 192.168.4.0 network segment is located goes through the eth3 routing table;
data packets to 103.49.10.0 network segment (public network) are to outer network, and apn1 routing table routing is carried out;
packets destined for 103.49.11.0 network segment (private network) are also destined for the foreign network, and travel apn2 routing table route.
It should be noted that, in practical applications, the routing rule is flexible to use, and the rule condition can be flexibly created according to actual needs by using the destination communication address information or the source communication address information as the determination condition.
In an optional embodiment, since the AP system is based on a Linux system kernel, and the Linux system kernel is configured to disable packet forwarding by default, the method may further include:
and configuring the kernel parameters by any one of a sysctl instruction, a mapping file for modifying the kernel parameters and a configuration file so as to start a routing function.
Specifically, the-w parameter of the sysctl command can modify the kernel parameter of Linux in real time, and the following commands are used: and (4) sysctl-w net, ipv4, ip _ forward equals 1, namely, the route forwarding can be started.
In summary, the network management method provided in the embodiments of the present application can make up for the deficiency of the existing Adaptive automotive architecture NM module function without increasing the cost, and can solve the problem of network packet routing between the computing units by adding the network configuration management and policy routing generation functions, so that the central computing unit can forward the packet to reach the designated network.
