Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The embodiment of the invention can be transmitted packet and carry out rational management, makes the packet that transmits in the sensor network packed through rational time window arrangement and be sent among another network.Fig. 1 is the flow chart according to the data packet forwarding method of the embodiment of the invention.The method of Fig. 1 is carried out by gateway device.
101, receive packet, and confirm the application layer data attribute and/or the delay requirement of this packet from sensor network.
102, according to the application layer data attribute and/or the delay requirement of this packet, confirm the time window that this packet is affiliated, this packet of storage in determined time window corresponding storage territory.
103, when arriving the delivery time of current time window, the packet of storing in the current time window corresponding storage territory is packed, and the packet after will packing is sent to another network.
The embodiment of the invention is used the forwarding mechanism based on time window; According to the attribute of packet or the time window under the delay requirement specified data bag; Packing is transmitted to the timing data packet in the time window; Thereby reasonably the transmitting time of different pieces of information bag is dispatched, and reduce the transmission delay of the high packet of instantaneity.
In the embodiment of the invention, utilize time window to solve the packet queuing problem.Fig. 2 is the sketch map according to an example of the time window of the embodiment of the invention.In the example of Fig. 2, suppose that gateway uses 6 time windows, i.e. time window shown in the left side of Fig. 20 to time window 5.The unit interval of each time window is T, for example T=10ms.Suppose that time window 0 is the current time window.
Gateway can be used for depositing the packet that receives for the certain storage area of each time window application.The size in each time window corresponding storage territory can be to satisfy the long Lmax of maximum bag of external network protocols regulation.Shown in Fig. 2 the right is the example of a time window, and wherein dash area is the packet of having stored in the respective memory regions, and the space size that occupies is Ls.Blank parts is the remaining space in the storage area, and size is Lr.The big or small summation of dash area and blank parts is the big or small Lmax=Ls+Lr of storage area.
Gateway receives the packet of self-sensing net; The application layer data attribute and/or the delay requirement of read data packet; Be saved in (dash area among Fig. 2) in the corresponding storage area to packet successively, that is to say that the order of packet queuing in the storage area is exactly the order that gateway receives packet.Gateway can be preserved these packets according to time window, sends these packet packings until gateway.
The transmission of the packet of storing in the slip of time window and the time window corresponding storage territory can be controlled through timer.Fig. 3 is the schematic flow diagram of data packet forwarding method according to another embodiment of the present invention.
The method of Fig. 3 is carried out by gateway device, utilizes the slip of timer loop control time window.The method of Fig. 3 is described below in conjunction with Fig. 2.
300, start timer, the length of this timer equals the unit interval of time window.For example, if the unit interval of time window is T, then the length of timer also is T.
When this timer expires, the current time window is become next time window of this current time window, and restart timer.In addition, the delivery time of current time window is the overdue moment of timer of current time window.In other words, time window slides, and gateway can start timer, whenever just sends the packet (if any) in this time window corresponding storage territory through a window time T.
For example, suppose as shown in Figure 2ly, the slip of time window is counterclockwise order in proper order.Gateways and starting timer, timer length are T, promptly after the gateway elapsed time T, and the packet in the transmitting time window 0 (that is, the current time window), at this moment, time window 0 rotates counterclockwise the time window into the maximum numbering, becomes new time window 5.Simultaneously, time window 1 rotates counterclockwise to time window 0 (that is, the time window slogan deducts 1), becomes new current time window.Other times window 2-4 rotates successively, the time window slogan of conversion oneself (for example, separately time window slogan deduct 1).
Should note; The process 300 of present embodiment can be carried out before the reception packet, can when receiving packet, carry out (for example, operated to trigger by the reception of packet and start timer); Possibly after receiving packet, carry out through behind the certain hour, the present invention does not limit this yet.
In addition, though among Fig. 3 process 300 is shown as execution before process 301, the embodiment of the invention is not limited thereto.Process 300 also can be carried out with process 301 or after process 301, carried out simultaneously.These variations all fall in the scope of the embodiment of the invention.
301, be similar to 101 of Fig. 1, the application layer data attribute and/or the delay requirement of definite packet that is received.
The application layer data attribute or the delay requirement of the packet that produces to the different application scene possibly be different.The delay requirement of packet representes that gateway can preserve the time of this packet, and gateway just can be within the scope of this time, and packet is packed and transmitted.For example, the delay requirement of packet can show as concrete time value, for example 5ms, 15ms etc.Perhaps, the delay requirement of packet can represent that the delay requirement of limit priority representes that this packet is the emergency data bag with priority, needs to transmit immediately.Priority is low more, and being illustrated in the time of preserving at the gateway place can be long more.
The application layer data attribute of packet can be represented the Business Nature of this packet, as representes that this packet is that temperature, humidity etc. are measured the packet of using generation.The application layer data attribute of packet is defined by the sensing net, also can reflect the urgency level that packet is transmitted.For example, the packet that the application that instantaneity is had relatively high expectations (like security alarm etc.) is produced is the emergency data bag, needs to transmit immediately.Other use the suitably delayed delivery of packet that produces.
Need to prove; According to the actual conditions of current communication, when sensing net and external network communication, can't obtain end-to-endly and control traditional QoS (Quality of Service; But can easily extract the application layer data attribute or the delay requirement of packet quality of service).
302, be similar to 102 of Fig. 1, according to the application layer data attribute and/or the delay requirement of established data bag in 301, confirm the time window that this packet is affiliated, with this packet of storage in determined time window corresponding storage territory.
As stated, the application layer data attribute of packet and/or delay requirement have reflected the urgency level that this packet is transmitted.Can carry out quantification treatment,, confirm the delay value D of this packet according to the application layer data attribute and/or the delay requirement of packet.For example, be under the situation of time value at delay requirement, delay value D can be this time value.Perhaps, can stipulate the pairing delay value D of different application layer data attribute or delay requirement priority.
Obtain after the delay value D, can be according to the ratio between the unit interval T of the delay value D of packet and time window, the time window under the specified data bag.With reference to Fig. 2, time window 0 can be corresponding to 0＜D≤T, i.e. 0＜D/T≤1; Time window 1 can be corresponding to T＜D≤2T, i.e. 1＜D/T≤2; So analogize.In the example of Fig. 2; The maximum bag of the long external network no better than of the bag of the packet of time window 3 is long; But there is not packet in the time window 2; There is the delay value of a lot of packets to satisfy 3T＜D≤4T in the packet that this expression gateway is received, and do not have the delay value of packet to satisfy 2T＜D≤3T.
In addition; If the packet in some time window (time window 3 for example shown in Figure 2) is more; And the follow-up packet that belongs to time window 3 that still receives; Possibly cause these time window 3 corresponding storage territories not have enough remaining spaces to store follow-up packet, can be put into the follow-up data bag in the time window (for example, time window 4 or time window 5) of back this moment.The reason of doing like this is: the delay requirement of the packet in this time window all is the same, and follow-up packet arrives after with respect to the packet of having stored in this time window being, so in the time window that can only put behind.Thereby the bag that had both satisfied the external network defined is long, has also guaranteed the ageing of packet as far as possible.
Particularly, but the length L of judgment data bag whether greater than the remaining space Lr in determined time window corresponding storage territory.When L≤Lr, this packet of storage in determined time window corresponding storage territory.On the other hand, when L＞Lr, this packet of storage in next time window corresponding storage territory of determined time window.In addition, when also not having enough remaining spaces, can be stored to again next time window corresponding storage territory, perhaps in next time window, jump the queue in next time window corresponding storage territory.
303, be similar to 103 of Fig. 1, when arriving the delivery time of current time window, the packet of storing in the current time window corresponding storage territory is packed, and the packet after will packing is sent to another network (for example, Ethernet).
The delivery time of current time window 0 is the overdue moment of the timer of current time window 0.When if timer expires, the current time window is not stored packet in the 0 corresponding storage territory, the transmit operation of then can not packing.Perhaps, can from follow-up time window 1-5, take out packet, to the packet that the is taken out transmission of packing.
When if timer expires, the current time window has the storage packet in the 0 corresponding storage territory, then can be to the packet of the being stored transmission of packing.
In addition; Also have under the situation of remaining space in current time window 0 corresponding storage territory; Can from follow-up time window 1-5 corresponding storage territory, take out packet, and with the transmission of packing together of the packet of packet of storing in the current time window 0 corresponding storage territory and taking-up.Like this, can be in guaranteeing current time window 0 packet packed under the situation of sending, with the packet of back under the situation that resource allows also together packing send, that is to say as far as possible and fill a packet of packing.
At this moment; Gateway is when packing transmission to the packet of current time window 0; Can make following judgement: full if the packet of current time window 0 has been arranged, do not allowed to add new packet, so the gateway packet of current time window 0 of just can only packing; If the packet of current time window 0 not row is full, can allow to add new packet, gateway will judge under the situation that resource allows to take out how many packets from follow-up window when packing is sent so.The order of taking out packet from subsequent window is the sending order according to time window, from time window, take out successively behind the packet with current time window 0 in the packet transmission of packing together.
Do so not only and can make full use of bandwidth, especially can effectively reduce the follow-up forwarding time delay of waiting to send out the packet in the time window.
The window queuing and the window forwarding mechanism of routine data bag have been described above.Indicate under the situation of said packet for the emergency data bag that needs to transmit as early as possible at the application layer data attribute of packet and/or delay requirement, the embodiment of the invention can also be carried out special processing, to guarantee the ageing of emergency data bag.
Alternatively; In one embodiment, can transmit said emergency data bag immediately to another network, no matter and whether the time window under this emergency data bag can hold down this packet; Can not put into time window to this packet, to guarantee the ageing of this packet.Under the situation that resource allows, can also from time window 0-5, take out the suitable data bag, with the transmission of packing of this emergency data bag, thereby utilize bandwidth more fully.
As another embodiment, judge the storage condition in the current time window 0.The remaining space Lr that is less than or equal to said current time window corresponding storage territory in the length L of emergency data bag is (under the situation of L≤Lr); Immediately with the packet of storing in emergency data bag and the current time window 0 corresponding storage territory transmission of packing together, and no longer wait the timer timing behind time T, to send these packets.Because L≤Lr; The long long Lmax of maximum bag that can not exceed the external network permission of the overall budget of the packet of therefore packing together this moment; Can be when guaranteeing emergency data bag ageing, also guaranteed packet ageing in original time window 0, improved bandwidth availability ratio simultaneously.
For example, suppose that gateway has been received an emergency data bag when gateway timing during to time t, gateway will be the transmission of packing together of the packet in the time window 0 and this emergency data bag.Within the remaining time (T-t), gateway still can receive packet, then when time T, and the packet that belongs to time window 0 that gateway is received (T-t) the during this period of time transmission of packing.
As guaranteeing that the remaining space in the time window can hold an embodiment of emergency data bag, can be in time window 0 or time window 1, for these emergency data bags are reserved some resources.These resources can be not too many, just can reserve the resource that satisfies 1 to 2 packet in a time window.Because the emergency data bag is generally fewer, these reserved resource can satisfy the requirement of emergency data bag.
In addition, (during L＞Lr), transmit the emergency data bag immediately to another network, and the emergency data bag is not put into time window greater than the remaining space Lr in current time window 0 corresponding storage territory in the length L of emergency data bag.As another embodiment, under the situation that resource allows, can from current time window 0, take out the partial data bag, with the transmission of packing of this emergency data bag, thereby utilize bandwidth more fully.
Perhaps, (during L＞Lr), allow the emergency data bag to jump the queue in the length L of emergency data bag greater than the remaining space Lr in current time window 0 corresponding storage territory.Particularly; Can all or part of packet of storing in the current time window 0 corresponding storage territory be shifted and store among the follow-up time window 1-5; So that the remaining space Lr in current time window 0 corresponding storage territory more than or equal to the length L of emergency data bag, stores this emergency data bag then in the 0 corresponding storage territory of the current time window after above-mentioned transfer processing.
The method of the transmission data of the embodiment of the invention is according to the application layer data attribute and/or the delay requirement of packet; Packet to needing gateway forwards carries out simple classification; And designed a kind of forwarding mechanism based on time window, gateway in time window to the packet transmission of packing.The embodiment of the invention can improve the forwarding of gateway and handle bandwidth utilization when consider packet ageing.For example, in wireless sense network, through adopting said method, sensor acquisition to Various types of data can reasonably arrange and scheduling be transferred into external network through gateway, like Ethernet, thereby realize effective transmission of sensor data information.
