Example 2

An embodiment of the present invention provides a method for sending a packet. Referring to FIG. 2, the method includes:

Step 201: The first host receives a service flow sent by the first virtual machine, where the service flow carries a destination address of the service flow.

The first virtual machine is deployed on the first host, and the second virtual machine is deployed on the second host. When the first virtual machine sends the service flow to the second virtual machine, the first virtual machine firstly goes to the first virtual machine. A host sends a service flow, where the service flow carries at least the destination address of the service flow, and may also carry the identifier of the first virtual machine and the identifier of the second virtual machine; the first host receives the service flow sent by the first virtual machine, and step 202 is performed. .

The destination address can be the destination IP address (Internet Protocol), the destination port, or the destination MAC address (Media Access Control) address. The identifier of the first virtual machine may be the IP address of the first virtual machine, the name of the first virtual machine, or the number of the first virtual machine. Similarly, the identifier of the second virtual machine may be the IP address of the second virtual machine, The name of the second virtual machine or the number of the second virtual machine.

For example, the destination address is the destination port 80, the identifier of the first virtual machine is 192.231.31.252, and the identifier of the second virtual machine is 192.231.31.251. The first virtual machine sends a service flow to the first host. The flow carries the destination port 80, the identifier of the first virtual machine is 192.231.31.252 and the identifier of the second virtual machine is 192.23%. The first host receives the service flow sent by the first virtual machine.

Step 202: The first host acquires a service identifier of the service flow according to the destination address of the service flow.

Before the step, the user inputs the destination address and the service identifier to the first controller; the first controller receives the destination address and the service identifier input by the user, and stores the destination address and the service identifier entered by the user in the correspondence between the destination address and the service identifier. In the relationship.

The first controller sends a correspondence between the destination address and the service identifier to the first host, and the first host receives the correspondence between the destination address and the service identifier sent by the first controller, and stores the correspondence between the destination address and the service identifier.

Correspondingly, the step 202 may be: the first host obtains the service identifier of the service flow from the correspondence between the destination address and the service identifier according to the destination address of the service flow.

The first controller may be an SDN (Software Defined Network) controller or a VxLAN (Virtual eXtension xLAN) controller.

For example, the user inputs the destination address 80 and the service identifier 1025, the destination address 443 and the service identifier 2049, the destination address 5000 and the service identifier 4097, and the destination address 5001 and the service identifier 4098 to the first controller. The first controller receives the purpose of the user input. The address 80 and the service identifier 1025, the destination address 443 and the service identifier 2049, the destination address 5000 and the service identifier 4097, and the destination address 5001 and the service identifier 4098 store the destination address and service identifier entered by the user in Table 1 as follows:

Table 1

Destination address	Business identifier
80	1025
443	2049
5000	4097
5001	4098

For example, the first host obtains the service identifier of the service flow as 1025 from the correspondence between the destination address and the service identifier stored in Table 1 according to the destination address 80 of the service flow.

The service identifier field ranges from 65535, and 50 virtual machines can be deployed on one host. The service identifier field corresponding to each virtual machine ranges from 1 to 1024, that is, each virtual machine can define up to 1024 service identifiers for policy control of different services.

Step 203: The first host encapsulates the service identifier of the service flow into the packet, and sends a packet to the switch.

The packet includes an inner packet and an outer packet. In this step, the first host encapsulates the service identifier of the service flow into the outer packet.

The outer packet includes the source MAC address, the destination MAC address, the VLAN, the source IP address, the destination IP address, the VxLAN port, and the VxLAN header. The first host obtains the source MAC address, destination MAC address, VLAN, source IP address, and destination IP address of the service flow. The VxLAN port and the VxLAN header encapsulate the service ID of the source MAC address, destination MAC address, VLAN, source IP address, destination IP address, VxLAN port, VxLAN header, and packet of the service flow into the outer packet.

The inner layer packet includes the source MAC address, the destination MAC address, and the service flow, and the first host obtains the source MAC address, the destination MAC address, and the service flow of the service flow, and encapsulates the source MAC address, the destination MAC address, and the service flow of the service flow into the inner layer. In the message.

Step 204: The switch receives the packet sent by the first host, where the packet carries the service identifier of the service flow.

The switch receives the packet sent by the first host, and parses the outer packet of the packet to obtain the service identifier of the service flow. Step 205 is performed.

It should be noted that the switch can only parse the outer packet of the packet and cannot parse the inner packet of the packet.

Step 205: The switch acquires a processing policy of the packet according to the service identifier of the service flow.

Before the step, the user inputs the service identifier and the processing policy to the second controller. The second controller receives the service identifier and the processing policy input by the user, and stores the service identifier and the processing policy input by the user in the correspondence between the service identifier and the processing policy. In the relationship.

The second controller sends a correspondence between the service identifier and the processing policy to the switch, and the switch receives the correspondence between the service identifier and the processing policy sent by the second controller, and stores the correspondence between the service identifier and the processing policy.

Correspondingly, in step 205, the switch obtains the processing policy of the packet from the correspondence between the service identifier and the processing policy according to the service identifier of the service flow.

The processing policy can be any policy for processing packets, including a processing policy for discarding packets and a processing policy for performing operations other than discarding packets. For example, the processing policy can be a discarding policy or a forwarding policy. , redirection policies, or bandwidth-based path control policies.

The second controller may be an SDN controller or an OF (open flow table protocol) controller.

For example, the user enters the service identity 1025 and the processing policy to the second controller: normal forwarding, service identity 2049 and processing policy: drop, service identity 4097, and processing policy: redirect to low-weight path, service identity 4098, and processing policy: setting The bandwidth of the forwarding path is 100M, etc.; the second controller receives the service identifier 1025 input by the user and the processing policy: normal forwarding, service identifier 2049, and processing policy: discard, service identifier 4097, and processing policy: redirect to the low-weight path, Service ID 4098 and processing policy: set the bandwidth of the forwarding path to 100M, etc., and store the service identifier and processing policy input by the user in Table 2 as follows:

Table 2

Business identifier	Processing strategy
1025	Normal forwarding
2049	throw away
4097	Redirect to low weight path
4098	Set the bandwidth of the forwarding path to 100M.

For example, the switch stores the pair of service identifiers and processing policies from Table 2 according to the service identifier 1025. The forwarding policy for obtaining packets in the relationship is normal forwarding.

Step 206: The switch determines whether to send the packet according to the processing policy of the packet, if the packet is sent, step 207 is performed; if the packet is not sent, step 212 is performed;

Specifically, if the processing policy of the packet is used to discard the packet, it is determined that the packet is not sent; if the processing policy of the packet is used to perform operations other than discarding the packet, it is determined to send the packet. Text.

For example, the processing policy of the packet may be a drop policy, a forwarding policy, a redirect policy, or a bandwidth-based path control policy. If the processing policy is a discarding policy, it is determined that the packet is not sent; if the processing policy is a forwarding policy, a redirection policy, or a bandwidth-based path control policy, it is determined to send the packet.

Step 207: If the packet is sent, the switch determines at least one forwarding path for sending the packet according to the identifier of the first virtual machine and the identifier of the second virtual machine.

Before the step, the second controller acquires the topology of the physical network where the switch is located, and sends the topology of the physical network to the switch. The switch receives the topology of the physical network sent by the second controller and stores the topology of the physical network.

Correspondingly, the step 207 may be: if the packet is sent, the switch determines at least one forwarding path for sending the packet according to the identifier of the first virtual machine, the identifier of the second virtual machine, and the topology of the physical network.

The at least one forwarding path for sending the packet is determined according to the identifier of the first virtual machine, the identifier of the second virtual machine, and the topology of the physical network. The forwarding path is not described in detail.

Further, the switch obtains the path weight of each forwarding path according to the path identifier of each forwarding path in the at least one forwarding path.

Before this step, the user inputs a weighting rule to the second controller, and the weighting rule may be set according to the number of forwarding entities included in the forwarding path. The second controller receives the weighting rule input by the user, and generates a path weight of each forwarding path in the physical network according to the weighting rule, and stores the path identifier of each forwarding path and the path weight corresponding to each forwarding path in the path identifier and In the correspondence of path weights.

The second controller sends a correspondence between the path identifier and the path weight to the switch; the switch receives the correspondence between the path identifier and the path weight sent by the second controller, and stores the correspondence between the path identifier and the path weight.

Correspondingly, each piece is obtained according to the path identifier of each forwarding path in at least one forwarding path. The path weight of the forwarding path can be:

The path weight of each forwarding path is obtained from the correspondence between the path identifier and the path weight according to the path identifier of each forwarding path in the at least one forwarding path.

For example, the weighting rule input by the user to the second controller is: the path weight of the forwarding path including the forwarding entity between 1-5 is 500, and the path weight of the forwarding path including the forwarding entity between 6-10 is 400. The path weight of the forwarding path including the forwarding entity between 11 and 15 is 300, and the path weight of the forwarding path including the forwarding entity between 16 and 20 is 200, and the path weight of the forwarding path including the forwarding entity is 100. The second controller receives the weighting rule input by the user, and the path weight corresponding to the path 1 is 100 according to the weight rule, the path weight corresponding to the path 2 is 500, the path weight corresponding to the path 3 is 200, and the path weight corresponding to the path 4 is 300. Etc; the second controller stores path 1, path 2, path 3, and path 4 and their corresponding path weights in Table 3 below:

table 3

Path identifier	Path weight
1	100
2	500
3	200
4	300

For example, the switch determines, according to the identifier of the first virtual machine and the identifier of the second virtual machine, that the three paths for sending the packet are path 1, path 2, and path 3, respectively, and according to path 1, path 2, and The path identifier of path 3, the path weights corresponding to path 1, path 2, and path 3 from Table 3 are 100, 500, and 200, respectively.

Step 208: The switch selects a forwarding path from at least one forwarding path according to the processing policy of the packet.

If the processing policy of the packet is a forwarding policy or a bandwidth-based path control policy, one forwarding path is randomly selected from at least one forwarding path.

If the processing policy of the packet is redirection, the redirection condition included in the processing policy of the packet is obtained, and one forwarding path that satisfies the redirection condition is selected from the at least one forwarding path. For example, if the condition of the redirection is to select the forwarding path with the highest weight, then according to the path weight of each forwarding path, select one forwarding path with the highest path weight from at least one forwarding path; if the redirection condition is to select the forwarding with the lowest weight The path selects a forwarding path with the lowest path weight from at least one forwarding path according to the path weight of each forwarding path.

For example, if the processing strategy of the packet is to redirect to the lowest weight forwarding path, then the path with the lowest path weight selected from path 1, path 2, and path 3 is path 1.

Step 209: The switch acquires the bandwidth of the selected forwarding path according to the processing policy of the packet.

Each processing policy corresponds to the bandwidth of a forwarding path, and the bandwidth of the selected forwarding path is obtained according to the processing policy of the packet.

The bandwidth corresponding to the forwarding policy and the redirection policy is the default bandwidth. The bandwidth corresponding to the bandwidth-based path control policy is the bandwidth included in the processing policy.

For example, if the default bandwidth is 50M, the bandwidth corresponding to the forwarding policy and the redirection policy is 50M, and the bandwidth-based path control policy includes the bandwidth corresponding to the forwarding path being 100M.

Step 210: The switch sets a bandwidth size of the selected forwarding path according to the acquired bandwidth.

Specifically, the switch sets the bandwidth size of the selected forwarding path to the acquired bandwidth.

For example, if the selected forwarding path is path 1 and the acquired bandwidth is 100M, the bandwidth size of path 1 is set to 100M.

Step 211: The switch sends the packet to the second virtual machine according to the set forwarding path.

Specifically, the switch forwards the packet to the second host where the second virtual machine is located according to the set forwarding path, and the second host receives the packet sent by the switch, decapsulates the packet, and obtains the second virtual machine. The identifier and the service flow are sent to the second virtual machine according to the identifier of the second virtual machine.

Step 212: If the packet is not sent, the switch discards the packet.

If the processing policy is the discarding policy, the switch does not send the packet and discards the packet.

In the present invention, the packet sent by the first host where the first virtual machine is located is received, and the packet carries the service identifier of the service flow, and the service identifier of the service flow is set and encapsulated by the first host according to the destination address of the service flow. If the packet is sent, the packet is sent to the second virtual machine according to the processing policy. The packet carries the service identifier of the service flow, so that the packet can be controlled according to the service identifier of the service flow.
