The a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of protection of the invention.
The embodiment of the present invention provides a kind of data transmission method for uplink, and the method is applied in wireless router, as shown in figure 1,
The method includes：
101st, obtain multicast packet.
Wireless router described in the embodiment of the present invention, has multicast forwarding function, for receiving multicast source (i.e. multicast number
According to bag sender) multicast packet that sends, and the multicast packet receiving is forwarded to multicast group.In wireless router
Before execution multicast, receive and obtain the multicast packet that multicast source (i.e. multicast packet sender) sends, wherein, described group
Multicast group purpose IP address and multicast group target MAC (Media Access Control) address is included at least in the header of unicast packets；Multicast number can also be included
According to contents such as the version of bag, type, port, time-to-live.Exemplary, as shown in Fig. 2 Fig. 2 shows the embodiment of the present invention
A kind of schematic diagram of the multicast packet packet head providing, it should be noted that the exemplary only citing of Fig. 2, present invention enforcement
Example is to the particular content comprising in the header of multicast packet, to the byte number shared by the content of packet header and to have multicast functionality wireless
The concrete species of router is not construed as limiting.
In actual applications, may there are multiple multicast group IP address, those multicast group IP by record in a wireless router
The corresponding multicast group in address is probably permanent it is also possible to interim；Possibly a main frame in multicast group is only added to
It is also possible to a main frame is added simultaneously in multiple multicast group in one multicast group.Multicast group purpose IP address are used for identifying
One IP multicast group, wireless router parses to the multicast packet obtaining, and can obtain multicast group purpose IP address, its mesh
Be, by this multicast group purpose IP address, purpose IP address can be confirmed from the corresponding IP address of multiple multicast group,
And the packet of acquisition is sent the multicast member to multicast group purpose IP address.
102nd, obtain the corresponding MAC Address of multicast member in multicast group according to multicast group purpose IP address.
Terminal unit (main frame) sends, to multicast source, the solicited message adding certain multicast group, when multicast source allows this terminal
When equipment (main frame) adds certain multicast group, by there is the wireless router of multicast functionality by the IP address of this terminal unit (main frame)
And/or MAC Address etc. is capable of the information of unique mark terminal unit (main frame) and recorded, subsequently to carry out multicast packet
Transmission.It is added to the terminal unit (main frame) of multicast group, the continuation of multicast member identity can be selected or exit.
After terminal unit (main frame) asks to add multicast group, (report reports to send report message to wireless router
Literary composition), inform that this terminal unit of wireless router (main frame) has added multicast group.In terminal unit (main frame) to wireless router
When sending report message, carry the information of the unique mark terminal unit (main frame) of its own, such as MAC Address etc..
The MAC Address of terminal unit (main frame) is stored by wireless router, when wireless router need to be to the multicast group in multicast group
When member sends multicast packet, from the preset store path of wireless router, directly obtain multicast member pair in multicast group
The MAC Address answered.
It should be noted that when wireless router carries out the forwarding of multicast packet, depending on MAC Address, Er Feishi
The IP address of multicast member.IP address is that wireless router provides, the IP ground that different terminal units (main frame) is distributed
Location is different；And MAC Address is the physical address of network interface card, it is unrelated with network, that is, no matter by the hardware with MAC Address (as net
Card, hub, wireless router etc.) it is linked into the where of network, it has identical MAC Address, and MAC Address typically can not change
Become it is impossible to be set by the user.
103rd, the multicast group target MAC (Media Access Control) address in described multicast packet is replaced with described multicast member corresponding
MAC Address, generates unicast packet.
In the prior art, wireless router receive multicast source transmission multicast packet after, according to multicast group mesh
IP address determine multicast group after, multicast packet is forwarded, is set by all terminals being connected on this wireless router
Standby (main frame) receives this multicast packet successively；When all terminal units (main frame) being connected on this wireless router, and not
Exist however, it is determined that this multicast packet is its needs after the terminal unit in multicast group (main frame) receives multicast packet,
Then this multicast packet stored, use；If it is determined that multicast packet is not that it is required, then by the multicast packet receiving
Bag abandons；Both waste the bandwidth resources of wireless router, reduce the speed of the acquisition packet needing acquisition group packet.
In order to solve the above problems, wireless router parses to multicast packet, obtains the multicast group mesh that it comprises
MAC Address, and this multicast group target MAC (Media Access Control) address is replaced with the corresponding MAC Address of multicast member that step 102 obtains,
Multicast packet is converted to unicast packet.It is intended that only to the multicast member directive sending data in multicast group
Bag, rather than be all to send multicast packet to all terminal units (main frame) being connected on wireless router, can save no
The consumption of the unnecessary bandwidth resources of line router, can also improve the speed needing to obtain multicast packet simultaneously.
It should be noted that described multicast packet is identical with the data included in unicast packet, difference
It is, the hop count when forwarding to it for the wireless router has differences.For the forwarding of unicast packet, no circuit
Transmit identical unicast packet to multiple recipients's (multicast member) it is also necessary to replicate many parts accordingly by device simultaneously
Identical unicast packet；For the forwarding of multicast packet, wireless router gives multiple recipients simultaneously, and (multicast forms
Member) transmission identical multicast packet, forward a identical data packet.
104th, described unicast packet is respectively sent to the multicast member in described multicast group.
In actual applications, the multicast packet described in the embodiment of the present invention is multicasting video data bag.Exemplary, family
When in front yard, multiple stage TV uses Set Top Box to watch same TV programme, multicast source can be to the wireless routing being connected with this Set Top Box
Device sends multicasting video data bag；Or, when the personnel of certain company's difference meeting room watch same video conference, different meeting rooms
Main frame as multicast member, receive the multicasting video data bag obtaining from multicast source that wireless router sends.In order to just
In understanding, the embodiment of the present invention so that multicast packet is for multicasting video data bag as a example illustrates, however, it should be clear that should
Kind explanation mode is not intended to restriction multicast packet and is only capable of as multicasting video data bag；Described multicast packet can also be literary composition
Part multicast packet, application program (Application, APP) multicast packet etc., embodiment of the present invention here is no longer carried out
Repeat one by one.
Data transmission method for uplink provided in an embodiment of the present invention, first, wireless router obtains multicast packet, according to this group
Comprise the multicast member that multicast group IP address determines data to be received in multicast group in unicast packets, obtain this data to be received
The corresponding MAC Address of multicast member；Secondly, wireless router obtains multicast in multicast group according to multicast group purpose IP address
The corresponding MAC Address of group membership, the multicast group target MAC (Media Access Control) address in described multicast packet is replaced with described multicast member
Corresponding MAC Address, generates unicast packet；Finally, described unicast packet is respectively sent to the group in described multicast group
Broadcast group membership；Compared with prior art, in the embodiment of the present invention, wireless router, only to the multicast member in multicast group, orients
Send the unicast packet changed by multicast packet, rather than be to the all-network equipment transmission group connecting with wireless router
Unicast packets, can save substantial amounts of Internet resources, thus improving the speed that multicast member in multicast group obtains packet
And efficiency.
Further, as to the refinement of above-described embodiment and extension, obtained according to multicast group purpose IP address in step 102
When taking the corresponding MAC Address of multicast member in multicast group, first, determine the quantity of described multicast member, and according to described
The quantity of multicast member replicates the described multicast packet of same number；Secondly, described multicast packet is parsed, and
Obtain the target MAC (Media Access Control) address in multicast packet packet head；Finally, the target MAC (Media Access Control) address in described multicast packet packet head is replaced
It is changed to the corresponding MAC Address of described multicast member.
Exemplary, if the terminal unit (main frame) being connected to same wireless router has 50, wherein there are 10 ends
End equipment (main frame) belongs to same multicast group, and the IP address of multicast group is XX.XX.XX.1, when router forwards to this multicast group
During multicast packet, obtain the MAC Address of 10 terminal units (main frame) in multicast group respectively, by the multicast in multicast packet
Group target MAC (Media Access Control) address replaces with the corresponding MAC Address of described multicast member, replicates, generates 10 unicast packet, and respectively
10 multicast group target MAC (Media Access Control) address being sent in multicast group replace with the corresponding MAC Address of described multicast member；Rather than
All send packet to 50 terminal units (main frame) being connected to same wireless router.Particularly, when being connected to same road
By on device, and belong to the terminal unit (main frame) of non-multicast group membership more when, by way of described in the embodiment of the present invention, energy
Enough substantial amounts of acquisitions reducing the unnecessary bandwidth resources of wireless router, improve multicast member acquisition multicast packet again
Speed.
Further, in actual applications, may there is following situation：Although the multicast member in multicast group is at this
In multicast group, but, this multicast member is not intended to continue to the multicast packet of wireless router transmission；Or, no
Line router sends before multicast packet to this multicast group, and this multicast member does not actively exit this multicast group；In the case of those,
The unnecessary network resource consumption of wireless router still can be wasted.
In order to solve the above problems, wireless router multicast group purpose IP address to multicast group send multicast packet it
Before, send inquiry message to the corresponding multicast group of described multicast group IP address, described inquiry message is used for determining described multicast group
Interior multicast member whether receiving multicast data；According to described multicast member, the response message of described inquiry message is determined
The multicast member of data to be received in described multicast group.After determining the multicast member of data to be received in multicast group,
Only obtain the corresponding MAC Address of multicast member of data to be received in described multicast group, and to data to be received in multicast group
Multicast member send multicast packet conversion unicast packet.Therefore, in wireless router, multicast packet is carried out
During forwarding, the multicast member inquiry message not responded need not be transmitted, further reduce wireless router
Unnecessary bandwidth consumption, the multicast member improving data to be received obtains the speed of multicast packet
Optionally, after wireless router gets multicast packet, wireless router passes through to the group in multicast group
The mode broadcasting group membership's transmission inquiry message determines the multicast member of the data to be received in multicast group, if multicast member pair
The inquiry message that wireless router sends is responded, then confirm the multicast member that this multicast member is data to be received.
In actual applications, in order to allow the multicast member in multicast group get the content of this multicast packet, in wireless router
To in multicast group multicast member send inquiry message when, wireless router multicast packet is carried out parsing obtain this multicast
The content brief description of packet, and the content brief description of this multicast packet is carried in inquiry message, so that multicast
Group membership determines whether receiving multicast data bag.
It should be noted that a pair of the quantity one of the multicast member of quantity and data to be received that sends of unicast packet
Should；If the quantity of the multicast member of the unnecessary data to be received of quantity that unicast packet sends, waste wireless router
Unnecessary bandwidth consumption；If the quantity that unicast packet sends is less than the quantity of the multicast member of data to be received, lead
The multicast member causing the data partly to be received in multicast group does not receive unicast packet.
Start multicast in wireless router and turn unicast feature, and multicast packet is converted into after unicast packet, significantly
Improve the transmission speed of data, that is, the speed of the multicast member receiving data of data to be received also significantly improves.Exemplary
, with as a example UDP (User Datagram Protocol, UDP) it is assumed that multicast member has three, by group
Broadcast after video data bag is converted to unicast packet, the transmission rate of video data bag can be by averagely every original 3-5Mbps
Bring up to averagely every more than 20Mbps that is to say, that smooth playing can be brought up to by original smooth playing 480p video
1080P video.Wireless router receiving multicast data bag, and forwarded, send on the rate theory of multicast packet,
Under noisy environment, wireless router send multicast packet speed can reach 130Mbps；Noiseless
In the environment of, the speed that wireless router sends multicast packet can reach 300Mbps.
Further, before starting wireless router multicast forwarding function, need to detect and whether determine wireless router
Open multicast and turn unicast feature, this multicast turns unicast feature and controlled by a control button, if control button is opening,
Then explanation wireless router starts multicast functionality；If control button is closed mode, the not actuated multicast of wireless router is described
Function.In actual applications, no matter whether wireless router starts multicast functionality, and the user of this wireless router has no way of looking into
Feel, multicast turn unicast feature be turned on or off start when wireless router has multicast requirement；But it is present to ensure that
The promptness of transmitting multicast data, it is normally open that wireless router is defaulted as multicast functionality.
