Description
Technical Field
The present application relates to the field of VoIP systems, and in particular, to a method and system for automatically changing a MAC address in a media channel, a computer device, and a readable storage medium.
Background
VoIP system technology is a Voice call technology, in which Voice call and multimedia conference are achieved through Internet Protocol (IP), that is, communication is performed through the Internet. Other informal names are IP phone (IP telephony), Internet phone (Internet telephony), broadband phone (broadband telephony) and broadband phone service (broadband telephone service).
VoIP can be used for a plurality of Internet access devices including VoIP phones, smart phones and personal computers, and calls and short messages are sent through cellular networks and Wi-Fi.
VoIP system terminal registers to media gateway through signaling, calling is initiated by terminal, media gateway controls connection of calling. The main control board of the general media gateway is divided into a main single board and a standby single board, and the main board of the main control board is automatically switched to the standby board when the operation of the main board is abnormal. Because the MAC (physical) addresses of the main board and the standby board are not the same, part of the media stream passing through the media gateway after switching is not passed.
The reason is that a DSP (digital signal processing) chip does not support a tcp/ip three-layer protocol, and a GARP (message) updating MAC address message sent by a standby board of an MGC during switching is not processed by a terminal, so that a media stream sent by the terminal is also sent by an MAC of a main board of a front media gateway. So if both MGC and terminal are in the same network, this problem can occur without going through the routing gateway. The most conceivable method to solve this problem is to let the MGC let the host of the terminal learn the MAC address once again according to the media IP through the signaling message, and then send the learned MAC address to the DSP through the communication message of the host and the DSP, so that the media channel sends out the media packet with the new MAC. The number of terminals is very large, and sending out the messages at the same time occupies a large amount of system resources of the MGC, which causes a large load on the system and easily causes message congestion.
Therefore, the prior art is in need of improvement.

Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, 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 obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The inventor has found, through research, that in the prior art, as shown in fig. 1, a terminal registers to an MGC (media gateway controller) through a registration message of sip (Session Initiation Protocol) signaling, and the MGC (media gateway) may also be connected to a signaling gateway No. 7 through a relay No. 7. The terminal initiates a call, and the MGC (media gateway) controls the call to be connected. If terminal 1 can call the user on signaling gateway 7, MGC will connect the user on signaling gateway 7 to the call of terminal 1. The black lines are the working paths of the media streams. In order to ensure reliable service operation, the main control board on the MGC has a main board and a standby board, the external IP of the main control board is one, the external MAC addresses are one, and when the main board is abnormally switched to the standby board, a GARP (generic attribute registration protocol) message is sent out in the process of upgrading the standby board to the main board to allow the service connected with the GARP to update the MAC. If the terminal and MGC (media gateway) are connected through the IP gateway, the method is effective, the IP gateway can update the MAC, the terminal firstly sends a packet to the gateway, and then the gateway sends the packet to the MGC, if the terminal and the MGC have problems in the same network, the DSP of the terminal receives the media packet, the DSP can be a packet with components removed by the IP address and the MAC address sent by the host of the terminal, and the DSP does not support the tcp/IP protocol, so that GARP information does not play a role on the terminal, and the terminal can still use the MAC of the main control board of the prior MGC to send media streams to the MGC.
The host computer in the terminal controls the DSP, and the host computer establishes and destroys the media channel and configures the parameters of the media channel according to the call signaling sent by the MGC. Therefore, in the prior art, message congestion occurs in MGC (media gateway) motherboard switching. Message congestion can cause an exception in the implementation of the functionality.
In order to solve the above problem, in the embodiment of the present invention, the terminal learns the media packet by itself, and the terminal monitors whether the source MAC of the incoming RTP (media) stream of the media channel has changed, and if so, learns a new source MAC, and then sets the learned source MAC to the destination MAC of the corresponding learned channel, so that the destination MAC address of the media channel is changed, and the DSP sends out the RTP packet with the new destination MAC. The invention uses a packet sending a GARP to inform the external network equipment of changing the MAC address of the IP address.
The garp (generic Attribute Registration protocol) in the present invention is a generic Attribute Registration protocol that provides a mechanism for assisting in distributing, propagating and registering certain information (such as VLAN, multicast address, etc.) among switching members in the same switching network.
GARP itself does not exist as an entity in the switch, and application entities that follow the GARP protocol are called GARP applications, and the major GARP applications are GVRP and GMRP today. When a GARP application entity exists on a port of a switch, the port corresponds to a GARP application entity.
Through the GARP mechanism, configuration information on one GARP member can be quickly propagated to the whole switching network. The GARP members may be end stations or bridges. The GARP member informs other GARP members of registering or canceling the attribute information of the member through declaration or recycling declaration, and declares the attribute information of the registered or canceled counterpart according to the declaration or recycling of other GARP members.
The DSP in the embodiment of the invention is a digital signal processor mainly used for voice coding and decoding.
Various non-limiting embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 shows a method for automatically changing a MAC address of a media channel according to an embodiment of the present invention, where the method includes:
step S1, the terminal registers to the media gateway, and the media gateway is connected with the No. 7 signaling gateway through the No. 7 relay;
as shown in fig. 1, the terminal registers to the MGC through the registration message of sip signaling, and the MGC may also connect to the signaling gateway No. 7 through the relay No. 7. In the embodiment of the invention, the MGC is a media gateway and has basically the same function as the SS7 signaling gateway. The media gateway can also process signaling, otherwise, it can not accept interrupted sip message and signaling No. 7 of signaling gateway, and the media gateway has media board to process RTP media stream.
Step S2, the terminal initiates a call, and the media gateway controls the call to be connected;
the terminal initiates a call, and the MGC controls the connection of the call. If terminal 1 can call the user on signaling gateway No. 7, MGC will connect the user of signaling gateway No. 7 to talk to terminal 1. The black lines are the working paths of the media streams. In order to ensure reliable service operation, the main control board on the MGC has a main board and a standby board, the main board and the standby board have one external IP and one external MAC address, and when the main board is abnormally switched to the standby board, a GARP message is sent out in the process of upgrading the standby board to the main board to allow the service connected with the GARP message to update the MAC.
In the embodiment of the invention, when the standby board is started, a Garp packet is sent to inform the external network equipment of changing the MAC address of the IP address. Specifically, the steps S3-S5.
Step S3, when the main board is switched to the spare board due to abnormal work, the terminal learns the media package by self;
for example, when the main board is abnormally switched to the standby board, the GARP message is sent out in the process of upgrading the standby board to the main board to allow the service connected with the GARP message to update the MAC.
In the embodiment of the invention, the GARP message is sent when a standby board is upgraded to a main board when the main and standby of the MGC are switched, in order to ensure that the received network equipment can be received without packet loss, the GARP message can be sent three times continuously, the GARP message supports the processing of the equipment of a tcp/ip protocol stack, if the host of a terminal receives the message, the message can be processed, only the host does not send an RTP stream, and the DSP does not have the tcp/ip protocol stack, so the message can not be processed, but the DSP can discover that the source MAC of the sent packet is changed according to the received RTP packet, and can enable the host to send a command for updating the MAC to the host again through the event.
Step S4, the terminal monitors whether the source MAC of the media flow coming from the media channel is changed;
the terminal host monitors whether the source MAC address of the received media stream is changed or not when the media channel is activated.
Step S5, if there is a change, learning a new source MAC; and setting the learned source MAC to the destination MAC of the corresponding learning channel.
And the terminal monitors that the source MAC of the media stream coming from the media channel is changed, learns the new source MAC and informs the external network equipment to change the MAC address of the IP address, and sets the learned source MAC to the destination MAC of the corresponding learning channel.
For example, a digital signal processor monitors that an event of changing a source MAC address is reported to a host computer, and the host computer starts event counting;
when the event count of the MAC exceeds 3 times and the source MAC in the packet of 3 times is the same, the source MAC before the event does not send the packet to the media channel any more, the host learns a new MAC according to the event and sets the MAC as the destination MAC of the channel to the media channel.
The media channel automatically changes the MAC address method, wherein if there is a change, a new source MAC is learned; the step of setting the learned source MAC to the destination MAC of the corresponding learning channel further comprises:
the digital signal processor uses the new MAC to package the MGC and the event of the source MAC change disappears.
In one embodiment, when the main board is abnormally switched to the standby board, because the MGC (media gateway) sends a media packet (RTP packet) to the terminal through a new MAC address after the switching, the terminal can receive the packet, and only the terminal sends the MAC packet to the MGC (media gateway) using the MAC (physical) address of the previous main board as a destination MAC, the MGC (media gateway) cannot receive the media packet.
Since the received media packets have the same packet information, such as source IP, source port, destination IP, and destination port, except for the MAC address, the DSP (digital signal processor) can determine from this information that the source MAC for that media channel has changed. In the embodiment of the invention, if the source MAC address is monitored to be changed, the event is reported to the host, and the host sets the source MAC as the destination MAC of the channel media stream, so that the DSP sends the media stream according to the new MAC address.
In the embodiment of the invention, in order to prevent MAC attack, after the event is received, the previous MAC is judged not to be sent, and the learned MAC is set to the DSP (digital signal processor) only according to the packet which is sent from the time point of each packing time length in the continuous 3 packing time lengths of the new MAC standby board. Therefore, in the embodiment of the invention, the MGC (media gateway) is not required to transmit a plurality of messages for modifying the media connection to each terminal in a centralized way, the system resources are not occupied too much, and the terminal updates the MAC (physical address) through self-learning. The general packing time is 20ms, and 3 continuous packets are 60ms, and the MGC (media gateway) that loses the packets also has corresponding packet loss compensation processing, so that people cannot perceive that there is a handover.
In one embodiment, when the main board is switched to the standby board due to abnormal work, the method specifically comprises the following steps:
firstly), the terminal host issues and monitors whether the source MAC (physical) address of the received RTP stream (media stream) is changed when the media channel is activated;
secondly, the DSP (digital signal processor) monitors that the event of the change of the source MAC address is reported to the host, and the host starts event counting;
and thirdly) when the event count of the MAC exceeds 3 times and the source MACs in the packets of 3 times are the same, the source MAC before the event does not send the packets to the media channel any more, host learns a new MAC according to the event, and sets the MAC as the destination MAC of the channel to the media channel.
And fourthly) the DSP uses the new MAC to send a packet to the MGC, and the event of changing the source MAC disappears.
In the method of the embodiment of the invention, the terminal self-learns the media packet, the terminal monitors whether the source MAC of the RTP flow coming from the media channel is changed, if so, the new source MAC is learned, and then the learned source MAC is set to the destination MAC corresponding to the learned channel, so that the destination MAC address of the media channel is changed, and the DSP can send out the RTP packet by using the new destination MAC. For example: before the MGC (media gateway) is switched, the MGC uses 001122334455 as a source MAC to send RTP packets to the terminal, and the terminal sends RTP packets to the MGC by using 001122334455 as a destination address. After the switch, the MGC uses 001122334466 to send the source MAC packet to the terminal, at this time, the terminal detects that the source MAC of the packet has sent the change, the source MAC of the packet is learned and reported to the host of the terminal through the event, the host uses the command of setting the channel MAC to update the learned MAC to the DSP as the destination MAC of the channel, so that the DSP sends the RTP with the new MAC, and the main board upgraded from the standby board of the MGC can receive the RTP packet from the terminal.
The invention does not occupy a large amount of system resources of the MGC and does not cause great load to the system, thereby effectively avoiding the message congestion.
