For example, may include that higher level regards networking Modem (modem) and junior's view networking depending on networking gateway equipment Modem.Higher level can be used as the first view networking gateway equipment depending on networking Modem, can also be used as the second view networking gateway equipment. Likewise, junior can be used as the first view networking gateway equipment depending on networking Modem, it can also be used as second and set depending on networking gateway It is standby.One higher level can connect with multiple juniors depending on networking Modem depending on networking Modem.

It may include the first internet device and the second internet device in internet.For example, internet device can be with Including Dropbox server and Dropbox client.Dropbox server can be used as the first internet gateway device, can also be used as Two internet gateway devices.Likewise, Dropbox client can be used as the first internet gateway device, second can also be used as mutually Networking gateway equipment.Dropbox server is view networking data storage Dropbox system.Dropbox client can be in PC (personal electricity Brain), mobile phone, the upper client software installed such as tablet computer, for logging in Dropbox server, read-write network disk data etc..

For example, the first internet device is Dropbox client, first, which regards networking gateway equipment, regards networking Modem as junior, Second, which regards networking gateway equipment, regards networking Modem as higher level, and the second internet device is Dropbox server.Alternatively, the first interconnection Net equipment is Dropbox server, and first, which regards networking gateway equipment, regards networking Modem as higher level, and second regards networking gateway equipment as under Grade view networking Modem, the second internet device is Dropbox client.

Referring to Fig. 6, a kind of step flow chart of data processing method of the embodiment of the present invention two is shown.

Step 601, first the IP datagram text that first internet device is sent is received depending on networking gateway equipment.

First internet device is communicated with first depending on internet protocol-based between networking gateway equipment, the first view connection Net gateway and second depending between networking gateway equipment based on being communicated depending on networking protocol, the second view networking gateway equipment and Internet protocol-based is communicated between second internet device.

First internet device will be sent to first depending on networking gateway equipment IP data be encapsulated as IP datagram text, will The IP datagram text is sent to the first view networking gateway equipment.

Step 602, first depending on networking gateway equipment judge whether there is with remaining space having used view networking message. In the presence of, execute step 603, in the absence of, execute step 604.

First receives IP datagram text depending on networking gateway equipment, due to passing the IP datagram text in depending on networking It is defeated, therefore first is packaged IP datagram text depending on networking message depending on networking gateway equipment utilization.

First depending on including multiple ports communicated with the first internet device, such as VLAN in networking gateway equipment (Virtual Local Area Network, virtual LAN) port, each port are corresponding with a view networking tunnel.Cause This, first view networking gateway equipment by receive the first internet device send IP datagram text port, that is, can determine and The corresponding view networking tunnel for being used for transmission IP datagram text in the port.

The corresponding mark in every view networking tunnel, the mark have for marking this to regard to whether there is in networking tunnel Remaining space has used view networking message.Therefore, step 602 may include: first depending on networking gateway equipment obtain for passing The corresponding mark in view networking tunnel of defeated IP datagram text；In the presence of the mark is marked as, judging result is to exist；? In the absence of the mark is marked as, judging result be there is no.

Step 603, first regard networking gateway equipment judging result as in the presence of, according to the length of the IP datagram text It spends, has used view networking message using described, or used to regard networking message and be not used described in and regarded networking message, envelope Fill the IP datagram text.

There is regular length depending on networking message.Since the length situation of IP datagram text is more, if according to all length Exhaustive division can not be such that the problem is preferably solved, and increase the complexity of problem.Therefore, the present invention is implemented Example in consider IP datagram text actual conditions, such as length it is larger (such as be greater than 1 depending on networking message length and be less than 1.5 view networking message length) IP datagram text it is more, can be by IP data in order to simplify the complexity for the treatment of process Message is divided into three classes, and one kind is the IP datagram text that length is less than or equal to the first default value, and one kind is that length is greater than first in advance If numerical value and the IP datagram text for being less than or equal to the second default value, one kind is the IP datagram that length is greater than the second default value Text.Wherein, the first default value can be set to the half for being equal to the length of view networking message, and the second default value can be with It is equal to the length of view networking message.

Step 603 may include:

A1 has used view to network when the length of the IP datagram text is less than or equal to the first default value using described The remaining space of message encapsulates the IP datagram text.

When the length of IP datagram text is less than or equal to the first default value, the residue for having used view networking message is empty Between can carry whole IP datagrams text, therefore can use the remaining space encapsulation IP for use view networking message Data message.

After encapsulating the IP datagram text using the remaining space for having used view networking message, the first view networking Gateway can also will be used for transmission IP datagram text regard the corresponding flag tag in networking tunnel as there is no.

A2, when the length of the IP datagram text is greater than the first default value and is less than or equal to the second default value, benefit With it is described using the remaining space depending on message of networking encapsulate in IP datagram text with the remaining space equal length Part, and a unused space depending on message of networking is divided, utilize the part of the unused view networking message empty Between encapsulate remainder in IP datagram text.

The IP datagram text length be greater than the first default value and be less than or equal to the second default value when, it is described It can use described used with bearing part IP datagram text, therefore using the remaining space depending on message of networking and regard networking The remaining space packed part IP datagram text of message, and remainder IP datagram is encapsulated using view networking message is not used Text.

Since the length of IP datagram text is less than or equal to the second default value, unused view networking message is being utilized When, it can use the segment space encapsulation remainder IP datagram text that view networking message is not used.Therefore, not by one It is divided using the space depending on message of networking, encapsulates the IP data using the segment space of the unused view networking message The step of remainder in message may include: that the space average that one is not used view networking message is divided into two skies Between；The remainder in the IP datagram text is encapsulated using the unused previous space depending on message of networking.At this point, institute It states to be not used and becomes to have used view networking message depending on networking message, and this has used view networking message to have remaining space, remains Complementary space is the latter space for having used view networking message.

Divide it encapsulating the remainder in the IP datagram text using the unused segment space depending on message of networking Afterwards, the first corresponding flag tag in view networking tunnel that can also will be used for transmission the IP datagram text depending on networking gateway equipment To exist.It is existing to have been made as latter space using regard network message namely above-mentioned remaining space with remaining space With view networking message.

A3 has used view networking message using described when the length of the IP datagram text is greater than the second default value Remaining space encapsulate the part in IP datagram text with the remaining space equal length, and view is not used using one Networking message encapsulates the remainder in the IP datagram text.

When the length of the IP datagram text is greater than the second default value, the residue for having used view networking message is empty Between can with bearing part IP datagram text, therefore, can use it is described use view network message remaining space packed part IP datagram text, and networking message encapsulation remainder IP datagram text is regarded using being not used.

Since the length of IP datagram text is greater than the second default value (and length of less than 1.5 view networking messages), because This can not divide the unused space depending on message of networking, not using one when using view networking message is not used Use the space encapsulation remainder IP datagram text of view networking message.

After the remainder encapsulated in the IP datagram text depending on networking message is not used using one, the first view connection Net gateway can also will be used for transmission IP datagram text regard the corresponding flag tag in networking tunnel as there is no.

Step 604, first regard networking gateway equipment judging result as in the absence of, according to the length of the IP datagram text Degree is not used view networking message using at least one and encapsulates the IP datagram text.

Step 604 may include:

View networking report is not used by one when the length of the IP datagram text is less than or equal to the first default value in B1 The space of text is divided, and encapsulates the IP datagram text using the segment space of the unused view networking message.

When the length of the IP datagram text is less than or equal to the first default value, one be not used view network message can be with Whole IP datagram texts are carried, and can use the segment space that one is not used view networking message and encapsulate whole IP datagrams Text.

One unused space depending on message of networking is divided, utilizes the part of the unused view networking message empty Between encapsulate the IP datagram text step may include: by one be not used view networking message space average be divided into two Space；Whole IP datagram texts are encapsulated using the previous space of the unused view networking message.At this point, the unused view Networking message becomes to have used view networking message, and this has used view networking message to have remaining space, and remaining space is This has used the latter space of view networking message.

After encapsulating the IP datagram text using the segment space of the unused view networking message, the first view networking Gateway can also will be used for transmission literary the regarding of the IP datagram and network the corresponding flag tag in tunnel to exist.It is existing Having used with remaining space regards networking message namely above-mentioned remaining space and has used view networking message as latter space.

B2, when the length of the IP datagram text is greater than the first default value and is less than or equal to the second default value, benefit View networking message is not used with one and encapsulates the IP datagram text.

When the length of the IP datagram text is greater than the first default value and is less than or equal to the second default value, one is not Whole IP datagram texts can be carried using depending on networking message, and the unused space depending on message of networking can not be drawn Point, the space that view networking message is not used using one encapsulates whole IP datagram texts.

After view networking message is not used using one and encapsulates the IP datagram text, the first view networking gateway equipment is also Can will be used for transmission IP datagram text regard the corresponding flag tag in networking tunnel as there is no.

View networking message is not used using one when the length of the IP datagram text is greater than the second default value in B3 The part in the IP datagram text with the unused view networking message equal length is encapsulated, and view connection is not used by one again The space of network packet is divided, and is encapsulated in the IP datagram text using the unused segment space depending on message of networking Remainder.

The IP datagram text length be greater than the second default value when, one be not used view network message can carry Partial IP data message, therefore can use the space packed part IP datagram text that view networking message is not used, and again View networking message encapsulation remainder IP datagram text is not used using one.

When recycle one be not used view networking message encapsulation remainder IP datagram text when, can recycle one not Use the segment space encapsulation remainder IP datagram text of view networking message.Therefore, view networking message then by one is not used Space divided, encapsulate the remainder in IP datagram text using the unused segment space depending on message of networking The step of dividing may include: that a unused space average depending on message of networking is divided into two spaces again；Using it is described not The remainder in the IP datagram text is encapsulated using the previous space depending on message of networking.At this point, the unused view connection Network packet becomes to have used view networking message, and this has used view networking message to have remaining space, and remaining space is should The latter space of view networking message is used.

Step 605, first the IP datagram text and the not use of remaining space will be encapsulated depending on networking gateway equipment Depending on message of networking, the second view networking gateway equipment is forwarded to depending on networked server via described.

First depending on networking gateway equipment after being packaged to IP datagram text, can will encapsulate IP datagram text, And having used for remaining space does not regard networking message, is forwarded to the second view networking gateway depending on networked server via described Equipment.For encapsulating the IP datagram text and being temporarily detained using depending on networking message with remaining space.

Depending on may include view networking packet header in networking message, this is depending on may include source address and destination address in networking packet header Etc. information, source address can for first view be used for transmission in networking gateway equipment IP datagram text view network tunnel correspondence virtually The view networking MAC Address of terminal, destination address can be the view networking MAC Address of view networked server.First view networking gateway Equipment will encapsulate the IP datagram text and having used for remaining space does not regard networking message, by being sent to view depending on networking In networked server.The encapsulation IP datagram text is received depending on networked server and having used for remaining space does not regard connection After network packet, can network MAC Address and second according to the view of virtual terminal in the first view networking gateway equipment pre-saved Relationship is correspondingly connected with depending on networking MAC Address depending on virtual terminal in networking gateway equipment, searches view and network include in packet header the Virtual terminal view in the corresponding second view networking gateway equipment of view networking MAC Address of virtual terminal in one view networking gateway equipment Networking MAC Address.And source address and destination address in the packet header for regarding networking message are modified, source address modification is view the Internet services The view networking MAC Address of device, destination address are revised as virtual terminal view networking MAC in the find second view networking gateway equipment Address will encapsulate the IP datagram depending on networking MAC Address depending on virtual terminal in networking gateway equipment according to second found Text and not remaining space are networked tunnel using the corresponding view that view networking message is sent to the second view networking gateway equipment.

Step 606, second encapsulation IP datagram text and not remaining space are parsed depending on networking gateway equipment View networking message has been used, has obtained the IP datagram text, and the IP datagram text is sent to second internet and is set It is standby.

Second receives encapsulation IP datagram text depending on networking gateway equipment and remaining space use view connection After network packet, it is parsed, obtains IP datagram text therein.

Second depending on including multiple ports communicated with the second internet device in networking gateway equipment, such as the end VLAN Mouthful, each port is corresponding with a view networking tunnel.Therefore, the second view networking gateway equipment is by receiving view networking degree weapon hair The view networking tunnel for having used view networking message of the encapsulation the sent IP datagram text and not remaining space, that is, can determine With this depending on the corresponding port for being used for transmission IP datagram text in networking tunnel.It is used to pass by this depending on networking gateway equipment second The IP datagram text that parsing obtains is sent to the second internet device by the port of defeated IP datagram text.

In a kind of optional embodiment, in order to guarantee the performance parameters such as tunnel time delay, shake, can limit has residue Space used view networking message first view the networking gateway equipment residence time.For example, can be in encapsulation IP datagram Text and being timed using depending on networking start of heading delay with remaining space, and real-time detection has remaining space It whether is more than setting time threshold value the use of the residence time depending on message of networking.Described make with remaining space detecting When being more than setting time threshold value with the residence time of view networking message, view networking report has been used with remaining space by described Text is forwarded to the second view networking gateway equipment depending on networked server via described, and the first view networking gateway equipment is also Can will be used for transmission IP datagram text regard the corresponding flag tag in networking tunnel as there is no.Second view networking gateway Equipment parses the encapsulation IP datagram text and has used view networking message with remaining space, obtains the IP datagram Text, and the IP datagram text is sent to second internet device.Detailed process is referring to step 605 and step 606 Associated description.

The data processing method of the embodiment of the present invention can be applied to various the answering with data transmission such as testing throughput With in scene.In the following, being introduced by taking testing throughput process as an example, each numerical value therein is only intended to for example, simultaneously Not as the limitation to the embodiment of the present invention.

Handling capacity refers in the case where no frame loss, the maximum data rate that equipment can be received and be forwarded.It handles up Amount is as an important test parameter for measuring view networking tunnel performance.It, can when test regards the handling capacity in networking tunnel To use the IP datagram text of different length, such as 64 bytes, 128 bytes, 512 bytes, 1024 bytes, 1518 bytes, respectively The corresponding handling capacity of different length is tested out, view networking tunnel handling capacity detailed can be reflected.But since view is networked Tunnel has regular length based on visual telephone service of networking is regarded, depending on networking message, for example regards the view networking packet header for message of networking For 64 bytes, bearing message data segment is 1024 bytes, so transmitting similar 64 bytes, 128 bytes, 512 bytes, 1518 words When section etc. deviates 1024 bytes biggish message, by view network tunnel data when, cause the waste of bandwidth, cause to gulp down The amount of spitting parameter is lower.

Referring to Fig. 7, a kind of schematic diagram of encapsulation of IP datagram text in the related technology is shown.As shown in Figure 7, if using Which is packaged IP packet, then when transmission is greater than the IP packet of 1024 bytes, IP packet is split as two data Message is packaged into two view networking messages and sends, preceding 1024 byte of first view networking message bearing IP packet, second view The remainder of networking message bearing IP packet；When transmitting less than 1024 message, IP packet is directly packaged into 1 view connection Network packet.Therefore it when carrying larger or smaller IP packet transmission, is provided depending on networking tunnel throughput well below equipment Physical link bandwidth.It should be noted that the IP packet in Fig. 7 is the IP datagram text in the embodiment of the present invention.

If solved the above problems, existing major demands can be with are as follows: 1, how will not in complicated network environment IP datagram text with length is classified, and complicated problem is simplified, according to the different reasonable optimization of IP datagram text confirmation Scheme.2, how that all length is random due to there are many kinds of the length arrangement combinations of the IP datagram text that is transmitted in network The message queue of composition, by algorithm by all possibility all it is considered that the pole of the handling capacity to realization in the prior art It is big to be promoted.3, how to make full use of view networking message to improve the handling capacity of equipment, and legacy data link cannot be influenced and existed Time delay, the parameters such as shake.

It is maximum up to 1518 bytes due to minimum 64 bytes of IP datagram text, if according to all field exhaustive divisions, and The problem cannot be made preferably to be solved, and increase the complexity of problem.Therefore, IP datagram text can be divided into three Class is less than or equal to 512 bytes, between 512 bytes and 1024 bytes, between 1024 bytes and 1518 bytes.Change sentence It talks about, the IP datagram text that length is less than or equal to 512 byte lengths is uniformly considered a kind of, the space of such 512 byte of distribution Transmission；Length is greater than 512 byte lengths and is uniformly considered a kind of less than or equal to the IP datagram text of 1024 byte lengths, such Distribute the space propagation of complete 1024 byte；The IP datagram text that length is greater than 1024 byte lengths is uniformly considered one Class, the space propagation of such distribution one complete 1024 byte and 512 bytes.

In summary, two kinds of situations will be divided into depending on the space of 1024 bytes of message of networking to use: 1, by 1024 bytes Space used as a complete space；2, the space that the space of 1024 bytes is divided into two 512 bytes is used.

Referring to Fig. 8, a kind of schematic diagram of IP datagram text encapsulation of the embodiment of the present invention two is shown.As shown in Figure 8, when When IP packet length is less than or equal to 512 byte, two IP packets can be carried using a view networking message, gulp down equipment The amount of spitting doubles.When IP packet length is greater than 512 bytes and is less than or equal to 1024 byte, IP packet just directly uses one A complete view networking message carrying.When IP packet length is greater than 1024 byte, 3 view networking reports are can be used in two IP packets Text carrying, realizes handling capacity improving 1/2 (being not shown in this kind of situation map 8).It should be noted that the IP packet in Fig. 8 is For the IP datagram text in the embodiment of the present invention.

Due to guarantee the time delay in view networking tunnel, the performance parameters such as shake in realization, and limit IP datagram text Residence time in a device, therefore drive that is detained can have two using the transmission depending on message of networking with remaining space Kind mode: 1, message driving: message is continually sent, and the message to be forwarded newly entered will push since previous message forwards Remaining complementary space, to constantly push ahead, message is successively sent, and protects view networking tunnel performance in arriving for delay variation Card.2, timer driver message is sent: if the residence time for having used view networking message with remaining space is more than setting Threshold value, then message that the view will be networked is sent, subsequent 512 byte is no longer waiting for subsequent IP datagram text and uses, and makes to regard Tunnel performance of networking guarantees in arriving for delay variation.

In the implementation, every view networking tunnel is arranged a mark (flag is equal to 0 or 1), represents and be not present equal to 0 View networking message has been used with remaining space, has been represented equal to 1 and has used view networking message in the presence of with remaining space, It is unused using view networking message to have there remains 512 bytes before i.e., and also not sent has gone out.

The first situation shares 3 kinds of situations, IP datagram text length when receiving an IP datagram text and mark is 0 Less than or equal to 512 bytes, it is greater than 512 bytes and is less than or equal to 1024 bytes, be greater than 1024 bytes.Separately below by this 3 kinds of feelings Condition describes respectively: 1, IP datagram text length is sealed less than 512 bytes using preceding 512 bytes of a new view networking message IP datagram text is filled, is 1 by traffic sign placement, it is for later use.2, IP datagram text length is greater than 512 bytes and is less than or equal to 1024 bytes are networked message using a new view, the space which is put into this 1024 byte are sent, mark according to It is so 0.3, IP datagram text length is greater than 1024 bytes, first by IP datagram text fragment, uses a complete view networking report It 1024 bytes and is sent before text encapsulation first, is networked 512 bytes encapsulation second before message using a view, mark is set It is set to 1, it is for later use.

Second situation shares 3 kinds of situations, IP datagram text length when receiving an IP datagram text and mark is 1 Less than or equal to 512 bytes, it is greater than 512 bytes and is less than or equal to 1024 bytes, be greater than 1024 bytes.Separately below by this 3 kinds of feelings Condition describes respectively: 1, IP datagram text length has used the surplus of view networking message using with remaining space less than 512 bytes 512 byte spaces of remaininging encapsulate IP datagram text, are 0 by traffic sign placement.2, IP datagram text length is greater than 512 bytes and is less than Equal to 1024 bytes, the IP data are encapsulated using 512 byte space of residue depending on message of networking using with remaining space Preceding 512 bytes of message encapsulate the remaining number of IP datagram text using new preceding 512 byte depending on message of networking According to mark is still 1, for later use.3, IP datagram text length is greater than 1024 bytes and makes first by IP datagram text fragment 512 bytes before encapsulating first with 512 byte space of residue for having used view networking message with remaining space, use one A complete view networking message encapsulates second, is 0 by traffic sign placement.

The embodiment of the present invention sees the handling capacity that equipment can be improved, and increases bandwidth availability ratio.In test performance handling capacity When parameter, performance parameter index can be optimized, enhanced product performance.
