Description
Technical Field
The invention relates to the technical field of intelligent operation terminal equipment, in particular to a method and a device for adjusting an application program package sending strategy of multi-network-port equipment.
Background
With the development of broadband construction and telecommunication operator services, the applications borne by the intelligent network set top box are more and more, and networking modes are more and more diverse. The set-top box can be provided with three types of interfaces of a wired network, a wireless network and a virtual network interface, and can be accessed to different networks. For example, a wired network of the set-top box is accessed to an IPTV private network of an operator, a wireless network is accessed to an Internet public network, and a virtual network port is used for system control communication in home equipment. These three types of networks cannot be accessed by each other due to network construction and security requirements. The set-top box can have various applications to bear different services. For example, the IPTV application is used to access an operator IPTV private network to access web pages, videos, and the like. And the OTT video program is used for accessing an Internet public network and watching network videos. Virtual network ports are used for communication between different devices or different systems of the same device. There is also an application, such as multi-screen interaction. Such applications require the use of different networks at different stages. For example, a public network is required to be used in a multi-screen interactive device discovery phase, and an IPTV private network is required to be used in an IPTV video playing phase.
In the prior art, it is common practice to use a routing table to determine which port the traffic uses by recording IP address segments. Such as 10.32.131, the IP address of the network segment goes to the wired network and the other default network segment goes to the wireless network. This has the disadvantage of requiring a full enumeration of all segments of the wired network, and the lack of a wired network makes it impossible to use the inaccessible wireless network. This method is selected according to the destination IP address, and has a disadvantage that different ports cannot be selected according to different applications, or even different ports cannot be selected according to different states of the same application.

As a preferred embodiment, the method further comprises the steps of:
and when the system is manufactured, a new application program is installed or a user operates through a setting program, the packet sending rule address pool table is accessed and modified according to the requirements of the user.
As a preferred embodiment, the recording of the correspondence between the application package name, the life cycle state, and the portal specifically includes the following steps: when the application program installation method is called, an operation interface is popped up for a user to select the corresponding network ports for sending data at different stages of the application program, and the packet name, the class name, the life cycle state and the corresponding network ports of the application program are recorded in the packet sending rule address pool table.
As a preferred embodiment, the data forwarding module performs data forwarding according to the life cycle state, the monitored correspondence between the currently used or monitored IP port and the application package name, and the correspondence recorded in the packet-sending rule address pool table, and specifically includes the following steps:
and the data forwarding module inquires IP addresses of different network ports, and forwards the data packet to the corresponding network port by using an iptables command according to the life cycle state of the application program, the monitored corresponding relation between the IP port being used or monitored and the packet name of the application program and the corresponding relation recorded in the packet sending regular address pool table.

The method for adjusting the application program package sending strategy of the multi-network-port device comprises the following two aspects:
on one hand, a packet sending rule address pool table is established for recording the corresponding relation of the application program packet name, the life cycle state, the IP port and the network port. This table may be embodied in the form of a database. The system setup program, the monitoring module as described below, and the authorized application can access and modify this form. An application developer aware of this principle can fill in items of data into a table at the time of application development.
Because the third party developer may not know the table or the developed application program may not modify the table, a real-time monitoring module is established in the system of the embodiment of the invention for the application program development compatible with other third party developers. The module is responsible for acquiring the application program package name by inquiring the states of the network port and the port (the states of all service ports can be inquired through a netstat-a command) and combining with the PID in the inquiry process (the application program package name corresponding to the PID can be acquired through a ps command inquiry process), so that the corresponding relation between the application program package name and the port which is being used is addressed.

Abc applications are using the 2010 port, for example, wishing to bind to a wired network port.
And establishing a data packet forwarding module. The module is responsible for combining the life cycle state according to the address pool table of the packet sending rule. And forwarding the data packet sent by the application program to the corresponding network card.
On the other hand, in the Android system, the lifecycle of an application is rewritten. Including Activity onCreate (), onStart (), onResume (), onPause (), onSt op (), onDestroy () methods and Service onCreate (), onStartCommand (), o nBind (), onDestroy () methods. When these methods are called by the application, the data forwarding module is informed of the application package name and the lifecycle state. The operation state comprises the following steps: background program running period, foreground program running period, starting period, pause period, etc. The application developer can also combine the function with the class name, and the system can judge the function used by the application program by the way of the class name.
The management class of the installed application in the system is rewritten. And when the application program installation method is called, popping up an operation interface. The user is allowed to select the network card that the different stages of the application (corresponding to different classes of applications, including interfaces and services) wish to send data. And recording information such as the name, class name, internet access and the like of the application program package into the package sending rule address pool table. The purpose of sending data to different network cards is achieved when the application program is installed or when the state of the application program is changed through a setting program.
Referring to fig. 2, an embodiment of the present invention further provides an apparatus for adjusting a packet sending policy of an application program of a multi-portal device, where the apparatus includes:
a table creation and maintenance module to: creating a package sending rule address pool table, and recording the corresponding relation among the application package name, the life cycle state and the network port;
a real-time monitoring module for: monitoring the corresponding relation between the IP port being used or monitored and the application program package name in real time;

In a preferred embodiment, the table creation and maintenance module is further configured to:
and when the system is manufactured, a new application program is installed or a user operates through a setting program, the packet sending rule address pool table is accessed and modified according to the requirements of the user.
As a preferred embodiment, the system further comprises an application management module for: when the application program installation method is called, an operation interface is popped up for a user to select the corresponding network ports for sending data at different stages of the application program, and the packet name, the class name, the life cycle state and the corresponding network ports of the application program are sent to the form creation and maintenance module for recording.
As a preferred embodiment, the data forwarding module performs data forwarding according to the life cycle state, the monitored correspondence between the currently used or monitored IP port and the application package name, and the correspondence recorded in the packet-sending rule address pool table, specifically including the following steps:
and the data forwarding module inquires IP addresses of different network ports, and forwards the data packet to the corresponding network port by using an iptables command according to the life cycle state of the application program, the monitored corresponding relation between the IP port being used or monitored and the packet name of the application program and the corresponding relation recorded in the packet sending regular address pool table.
As a preferred embodiment, the lifecycle method includes Activity onCreate (), onStart (), onsemum (), onPause (), onStop (), onsestroy () methods and Service onCreate (), onStartCommand (), onBind (), onsestry () methods; the life cycle state comprises a program background running period, a foreground program running period, a starting period and a pause period.
Packet rules address pool table: the method is characterized in that the method exists in a terminal system, and can record the corresponding relation of the application package name, the life cycle state and the network port in a text and database mode, wherein the life cycle state and the application class name can be added according to the requirement or not. If the life cycle state does not exist, the application program corresponds to a certain network port at any time. Abc, for example, the application package name com. corresponding to an eth0 port, this application uses the eth0 port at any time.
An application may use the wlan0 in different states corresponding to different portals, e.g., com.bcd, background. Bcd application is represented using wlan0 port in the background (there is an interface, i.e. an Activity-enabled application will call the onPause (), onsop () methods in the background).
A real-time monitoring module: through commands or command combinations such as netstat, ps and the like, the corresponding relation between the IP port in the using state or the monitoring state and the application program packet name in use is inquired and monitored in real time. For example, the com.abc program is using port 8002 and the com.bcd application is using 8005 port in listening state.
A data forwarding module: and acquiring the corresponding relation between the IP port and the application program package name known by the real-time monitoring module. And inquiring IP addresses of different network ports. And forwarding the data packet by using an iptables command according to the corresponding relation recorded by the packet sending rule address pool table. For example, the IP address of eth0 port is 62.129.66.5, the IP address of wlan0 port is 192.168.43.13, the port used by co m.abc is 8002, and the port used by com.bcd is 8005. The message sent by the com.bcd application program can be transferred to the wlan0 network port by using an instruction ipta bles-T nat-A POSTROUTING-i eth0-p tcp-sport 8005-j DNA T-to-destination 192.168.43.13: 8005. The meaning of the command is as follows: -tnat indicates the source address and port in the modified packet, postoutputting indicates the source IP or port to be modified; -i eth0 represents the incoming packets from eth0 portal; -sport represents a source port; -ptcp denotes the matching TCP protocol; -j DNAT represents the destination NAT; -to-destination indicates the destination address and port converted. Since the processing is performed in the postoutputting chain, after the data is sent out, the target address is also wrapped according to the converted address, and the processing is not required to be performed subsequently.
Similarly, the method can be realized by using iptables-t nat-A POSTROUTING-i wlan0-p tcp-sport 8002-j DNAT-to-destination 62.129.66.5:8002, and the message of the com. abc application program is forwarded to the eth0 network port.
When the system is manufactured, a new application program is installed, and a user can modify the packet-sending rule address pool table through program setting operation.
As shown in fig. 1, the software processing flow process of the embodiment of the present invention is as follows:
step 101: establishing a package sending rule address pool table in an Android system for recording the corresponding relation of the package name, the life cycle state and the network port of an application program
