Referring to fig. 4-1, the embodiment of the invention provides a kind of methods for sending information, comprising:
Step 401, SR sends SR attribute information to coupled server, which includes at least the mark of SR
Know；
Wherein, SR can be connected directly with server, i.e. chain road between SR and server does not have other equipment, SR
It can be connected on server by other equipment, for example, SR can be connected on server by router.The mark of SR can
With include SR ID, SR UUID and/or SR management IP address etc..SR attribute information can also including SR interface type,
The SN number etc. that the flow table number and/or SR that interface index, the SR of SR is supported are supported.
Wherein, SR attribute information can be sent to server by LLDP message by SR, specifically:
SR selects a bit from the reservation bit position in the system capability field of LLDP message, by the bit position
Position, the data cell that the LLDP message is arranged carry SR attribute information, and the bit of the set is for indicating the LLDP message
Data cell carries SR attribute information, sends the LLDP message and gives its server being connected directly.
Referring to fig. 4-2, LLDP message includes DA, SA, Type, FCS and data cell.DA is used to carry target MAC (Media Access Control) address,
For LLDP message, target MAC (Media Access Control) address 01-80-C2-00-00-0E.SA is for carrying source MAC.Type is for carrying
Type of message, for LLDP message, the type of message that Type is carried is 0x88CC.FCS is for carrying frame check sequence.Data sheet
Member is the information exchange main body of LLDP message, can carry different information, and data cell carries SR in embodiments of the present invention
Attribute information.
Data cell includes system capability TLV and at least one system property TLV.The system capability in data cell
TLV is located at before system property TLV.It include system capability field in system capability TLV, the bit generation in system capability field
A kind of system capability of table, system property TLV is for carrying information.
System capability TLV shown in -3 referring to fig. 4, system capability TLV include TLV type field (TLV Type), ability/
Status word length field (Capabilities/Status String Length), system capability field (System
) and enabled capable field (Enable Capabilities) Capabilities.System capability field includes two bytes, i.e.,
16 bits.A bit in every kind of system capability correspondence system capable field of data cell, if some bit
Sign is set, then system capability TLV is for illustrating that data cell has the corresponding system capability of the bit.
For example, with reference to table 1, every kind of system capability shown in table 1 and the corresponding bit of every kind of system capability, such as table 1
Fifth line record, the record show the 4th bit in routing function correspondence system capable field.If system capability word
The 4th bit set in section, then system capability TLV is for illustrating the routing function that data cell has.
Table 1
| Bit | System capability |
| 1 | Repeater |
| 2 | Bridge |
| 3 | Access Point |
| 4 | Router |
| 5 | Telephone |
| 6 | Wireless Station |
| 7 | Station Only |
| 8-16 | Retain |
The 8th of system capability field still retains to sixteen bit bit as can be seen from Table 1.So of the invention real
It applies in example, a bit can be selected from the bit of reservation, and defining the corresponding system function of the bit is SR function
Energy.If the bit set of selection, show that data cell has the function of SR, and define the data cell energy with SR function
Enough carry SR attribute information.
System property TLV shown in -4 referring to fig. 4, system property TLV include TLV and payload part, and TLV for taking
Information type, each numerical value that TLV field is constituted represent a kind of information type.For example, with reference to table 2, TLV field is constituted every
A kind of information type that a numerical value represents, the information type represented such as numerical value 5 that TLV field is constituted are device name.Payload portion
Divide for carrying the corresponding information of the information type.
Table 2
Correspondingly, the data cell that the LLDP message is arranged carries SR attribute information, can be with are as follows:
The corresponding information type of TLV head carrying SR attribute information that the system property TLV of the LLDP message includes is set, if
The payload part carrying SR attribute information that the system property TLV of the LLDP message includes is set, the LLDP message is set to realize
Data cell carries SR attribute information.
Step 402, server receives the SR attribute information that SR is sent；
Specifically, server receives the LLDP message that SR is sent, and judges in the system capability field from the LLDP message
Reservation bit position whether be set, if be set, it is determined that the LLDP message carry SR attribute information, from the LLDP message
Data cell in extract SR attribute information.
Step 403: server obtains topological arrangement information, which includes SR attribute information and its own packet
The mark of the SN included.
It wherein, include at least one SN in server.There are SN lists in server, and the SN list is for storing its own
Including SN mark.The mark of SN unique identification SN, SN mark can be but unlimited in service chain network
In the management IP address of the UUID, and/or SN of ID, SN of SN.
This step can be that server selects the mark of SN, based on the received SR attribute information and selection from SN list
SN mark, establish the attachment relationship of SN and SR, the attachment relationship of the SN and SR include the mark of the SR and the SN of selection
Mark, and using the attachment relationship table of the SN and SR as topological arrangement information.The topological arrangement information can also include SR attribute
It is any in SN number that the flow table number and SR that the interface type of SR in information, the interface index of SR, SR are supported are supported etc.
It is one or more.
The mark of SN can be selected from SN list by the following two kinds mode, comprising:
The first, the mark for all SN for selecting SN list to include；
If including that the SN number that SR is supported is arranged according to the SN number that SR is supported from SN second, in the SR attribute information
The mark of SN is selected in table.
Wherein, there is a Virtual Machine Manager module, Virtual Machine Manager module can receive the SR of SR transmission in server
Attribute information, and obtain simultaneously memory topology configuration information.
Step 404, server sends topological arrangement information and gives business chain control system；
Include function library in server, in embodiments of the present invention, one is extended in function library for reading information
Function.In addition, management assembly is also arranged in the server, which has open interface, and the open interface is opened
It puts and gives business chain control system.A kind of implementation of the function library can be libvirt.
This step can be with are as follows: server calls the function for reading information from preset function library；Pass through the letter of calling
Number, which is stored in the management assembly of its own, which includes open interface.Business chain control
System calls the open interface of management assembly and calls the topological arrangement information from management assembly by the open interface.
Wherein, server calls topological arrangement information, then will call by the function called from Virtual Machine Manager module
Topological arrangement information be stored in management assembly.
Step 405: business chain control system receives the topological arrangement information, generates business link network according to topological arrangement information
Network topology.
Business chain control system is according to topological arrangement information, the SN for determining each SR and being attached on each SR, according to
The each SR and SN being attached on each SR generates business chain network topology.For example, the business chain network topology such as Fig. 4-generated
Shown in 5.
