For ease of illustration of present disclosure, it will only be discussed further referred to as " differentiated services ", " source address ", " destination The information field of location ", " source port " and " destination port ".About other information field, can be standardized from above mentioned RFC Obtain other explanations.

Information field " source address " designation date is grouped the IP address being originated from.Similarly, information field " destination-address " Designation date is grouped the IP address gone to.In IP version 4, source address and destination-address are 32 bit values.In IP version 6 In, source address and destination-address are 128 bit values.

Information field " source port " indicates the port numbers in the source of data grouping, and information field " destination-address " indicates Port numbers in the destination of data grouping.

Based on source address, destination-address, source port and destination port, IP stream of packets can be defined as in source address and The IP stream of packets between the second endpoint that first end point and destination-address that source port defines and destination port define.Including Source address, destination-address, source port, destination port and protocol identifier entity be also referred to as " 5 tuple of IP (tuple) ".

Information field " differentiated services " is included in 4 data grouping of IP version and in 6 data grouping of IP version.Such as exist The same defined in the specification of RFC 2474, information field " differentiated services " is 8 bit values.The structure of this information field is in Fig. 5 Schematically show.

As shown in figure 5,6 bits (that is, bit 0-5) of information field are for defining differentiated services code-point (DSCP).It is other Dibit is not used.Using DSCP, the forwarding of the controllable data grouping carried out by network node.For with different types of clothes It is engaged in related data grouping, different repeating process may be selected.DSCP can be standardized.In addition, some range is non-standard It is available to change DSCP.

Fig. 6 schematically shows the structure of the protocol frame according to 802.1 q of IEEE and 802.1 p standards.Protocol frame It is used on media access control (MAC) layer, and can be used for transmitting the grouping of the IP as described in conjunction with Fig. 3,4 and 5.IP data point Group then will include in the data field of protocol frame.

Protocol frame is started with preamble, and preamble is 1 and 0 alternate mode.The length of preamble is 7 bytes.Preamble It is frame start delimiter (SFD) later.Frame start delimiter has the length of 1 byte, and including 1 and 0 alternate mode, with Terminate for two continuous 1.It is 6 bytes and definition for defining the destination MAC Address (DA) of protocol frame after frame start delimiter 6 bytes of the source MAC (SA) of protocol frame.Next field includes tag protocol mark (TPID).8100 hexadecimal value Indicate 802.1 q/p agreement of IEEE.Next field includes Tag Control Information (TCI).As shown in the lower half of Fig. 6, label control Information processed includes 3 priority bits, is defined as 1 bit and virtual local area network mark of canonical format indicator (CFI) later Know 12 bits of (VLAN ID).TCI field is alternatively referred to as VALN label.It is the Type Length of 2 byte lengths after TCI field Field.This field instruction include in the data field of protocol frame MAC client data byte quantity, or use can Frame type identification is indicated when selecting format group binding and layout.It is data field after type length field, which can be 48 to 1500 The sequence of byte long.It is cyclic redundancy check (CRC) value after data field, which is generated by mac source device, and by MAC Destination device be used for verify received protocol frame integrality.

In TCI field, priority bit defines User Priority.Setting in relation to priority bit is to User Priority The details of mapping defined in 802.1 p standard of IEEE.CFI bit is for providing and Ethernet and token style type The compatibility of both networks.VLAN ID is for distinguishing different virtual LAN (VLAN).

According to concept as described herein, in the information in DL data grouping in local in communication device 100 Generate the packet classification rule for being used for UL data grouping.Furthermore, it is noted that in many feasible situations, IP data grouping Stream is usually two-way.Even if the transmission of effective load data only occurs in one direction, for example, being grouped based on TCP, IP points Group stream is generally also included within the control grouping transmitted in opposite direction, as TCP acknowledgment is grouped.In addition, the source of IP stream of packets and Destination IP address and port numbers are usually symmetrical, that is, destination endpoint in one direction (passes through IP address and port Number identification) it is identical as source endpoint (pass through IP address and port numbers identification) in another direction, and vice versa.Due to symmetrical Property reason, identical IP stream of packets reverse flow grouping will have " complementation " address designator and " complementation " port identifiers, this Mean that source identifier in one direction is identical as destination mark symbol in another direction.

According to the concept as described in following content, it will be assumed that DL data service is assigned to service class 50 in some way, And it is provided with corresponding mark.This can be realized by the business classifier 210 of network gateway node 220.In the example shown, it controls Node 300 sends network gateway node 220 by signal for DL packet classification rule 215.It is also possible, however, to use providing DL points Group classifying rules 215 arrives the other way of network gateway node 220.By using DL packet classification rule 215, mesh network joint Business classifier 220 in point 220 assigns DL to be grouped into service class 50, and correspondingly indicates DL data grouping.Pass through setting Dscp field in the header of data grouping, by the priority bit of setting data grouping, and/or by being mentioned for data grouping For VLAN label, it can be achieved that this is indicated.In addition, if outgoing data grouping will use tunnel agreement to transmit, then outgoing data divides This mark of group can also be realized by providing Tunnel Identifier for data grouping.

As described above, communication device 100 includes being operated based on UL packet classification rule 115 and supporting to generate UL grouping point The business classifier 110 of the reflective-mode of rule-like.In reflective mode, it includes first that business classifier 110, which is configured to detection, It is that the outgoing data that complementary second identifier accords with is grouped that the incoming data of identifier, which is grouped and includes relative to first identifier symbol,.? In complementary second identifier symbol, such as the purpose of destination IP address and/or destination port end element and first identifier accord with In the source point element such as source IP address and/or source port it is identical.First and second identifiers each can be 5 tuple of IP. By the received DL data grouping of monitoring institute, business classifier 110 is to assign the outgoing data point that there is complementary second identifier to accord with Group is regular to UL data classification is generated with the such mode for being grouped identical service class 50 with the incoming data that first identifier accords with 115.In this way, not requiring clearly to send communication device 100 by signal for UL packet classification rule 115.On the other hand, UL points Group classifying rules 115 can be flexibly adapted to specific communications situation, these situations can pass through DL business point by network operator Class controls.

In reflective mode, if business classifier 110 detects the new IP with incoming data grouping in dl direction Stream of packets, then it can automatically generate corresponding UL packet classification rule 115.If the incoming data grouping of IP stream of packets is each taken With specific 5 tuple of IP, then UL packet classification rule 115 will be configured to assign the outgoing data grouping for carrying complementation 5 tuple of IP Identical service class 50 is grouped to a received incoming data.In addition, UL data grouping is indicated according to its classification, such as By using identical mark in the DL data grouping with this service class.This mark can be by being arranged in the header of data grouping Dscp field is realized by providing VLAN label, and/or the priority bit by the way that data grouping is arranged for data grouping. In addition, if outgoing data grouping will be transmitted using Tunneling Protocol, then this mark of outgoing data grouping can also be by for data Grouping provides Tunnel Identifier to realize.

The structure of identifier and complementary identifier based on 5 tuple of IP is shown in FIG. 7.It is to be appreciated, however, that its The identifier and complementary identifier of its type are also possible.In general, in complementary identifier, at least one element of identifier Occur again as another element.For example, the identifier in the complementary identifier of outgoing data grouping, in incoming data grouping Source element can be used as destination element and occur again.According to an embodiment, identifier includes source address and destination-address, and And complementary identifier includes the source address of the destination-address corresponding to identifier and the purpose of the source address corresponding to identifier Way address.

As shown in fig. 7, the identifier based on 5 tuple of IP may include source address A, destination-address B, source port C, purpose Ground port D and protocol identifier X.Corresponding complementary identifier will thus have source address B, destination address A, source port D, destination Port C and protocol identifier X.In other words, in complementary identifier, compared with identifier, source address and destination are had exchanged Address.Similarly, in complementary identifier, compared with identifier, source port and destination port are had exchanged.Protocol identifier is protected It holds constant.In other embodiments, different types of identifier and complementary identifier can be used, for example, based on only 5 tuple of IP A part.For example, compared with identifier, being merely able to exchange source address and destination-address in complementary identifier.

In the following, it by by referring to structure as shown in Figure 1, is explained in greater detail according to the present invention one and implements The process of the processing UL data grouping of example.

Initially, UL data grouping (such as data grouping related with the special services such as IP-based voice service) exists While the default service class being assigned in the service class 50 such as internet service class, it can be transmitted to from communication device 100 Network gateway 220.Corresponding IP stream of packets is then also included within the data grouping that the side DL is passed up, for example, confirmation grouping.It is logical It crosses and uses DL packet classification rule 215, the business classifier 210 in network gateway node 220 will assign these DL data groupings To required service class, for example, voice service, and will realize the corresponding mark of DL data grouping.As mentioned above, this Mark can be related to be arranged in the dscp field in the header of DL data grouping, provides VLAN label for DL data grouping, is DL number Tunnel Identifier, and/or the priority bit of setting DL data grouping are provided according to grouping.

In reflective mode, the then detection Incoming DL data grouping of the business classifier 110 in communication device 100, and Based on complementary 5 tuple of IP of 5 tuple of IP in the grouping of received incoming data operated, generation UL business classification gauge Then 115.Herein, it will be appreciated that different IP stream of packets can have same service class 50, and multiple UL packet classification rules 115 It can be used for assigning out UL data grouping to a service class 50.

In addition to the reflective-mode for generating UL packet classification rule 115, other business point can also be provided for business classifier 110 Quasi-mode, for example, being operated based on the UL packet classification rule sent from network by signal, the UL based on static configuration points Group classifying rules is operated, or is operated based on port mapping.Reflective-mode, which can respond, for example to be communicated in initialization Control signal is received from network when connection between device 100 and network gateway node 220 and is activated, or at no point in the update process Activation.

It can also be provided for communication device 100 to communication network and indicate that it supports the above-mentioned reflection of generation UL classifying rules 115 The functionality of mode.For example, this can include to the connection initialization between communication device 100 and network gateway node 220 In.For example, information element can be added to the signaling used during connecting initialization.By means of this information element, communication dress Its supporting reflex mode can be indicated by setting 100.And network can indicate whether use instead by signal to network equipment 100 Emission mode.

In some embodiments, communication device 100 supports that the information for generating the reflective-mode of UL classifying rules 115 can also be Distribute between network node, for example, being distributed to control node 300.

It can be subgroup (such as being only a service class) selectively activation life of service class 50 according to some embodiments At the reflective-mode of UL classifying rules 115.For example, reflective-mode only can be activated for voice service and/or multimedia service.Such as Fruit and it is not all application or service require activation reflective-mode, then this can be useful.For example, in some cases, clothes 5 tuple of IP in the data grouping of business can static defining, and corresponding static state UL packet classification rule 115 can be in communication device It is used in 100.In addition, port mapping can be used in some service class 50, and divide to the business of one or more of the other service class Class is realized in reflective mode.
