Abstract
In a method for sending packet traffic, an access device transmits a first part of to-be-transmitted traffic to a forwarding controller for check. After the check is passed, the forwarding controller forwards the first part of the to-be-transmitted traffic. The access device transmits a second part of the to-be-transmitted traffic to a first forwarding node, and the first forwarding node forwards the second part of the to-be-transmitted traffic based on received forwarding indication information and forwarding information of the to-be-transmitted traffic.
Claims28
A method for sending packet traffic and comprising:
- transmitting, by an access device, to a forwarding controller, and according to a first forwarding path of to-be-transmitted traffic, a first part of the to-be-transmitted traffic for performing a check on the to-be-transmitted traffic according to a check policy, wherein the check policy is for checking access permission of the to-be-transmitted traffic or a forwarding policy of the to-be-transmitted traffic;
- forwarding, by the access device, to a destination of the to-be-transmitted traffic, and after the check passes, the first part;
- and
- transmitting, by the access device and to a first forwarding node located on the first forwarding path, a second part of the to-be-transmitted traffic for the first forwarding node to send the second part to the destination based on forwarding indication information,
- wherein the forwarding indication information instructs the first forwarding node to send the to-be-transmitted traffic to the destination.
A system for sending packet traffic and comprising:
- an access device configured to:
- transmit, to a forwarding controller according to a first forwarding path of to-be-transmitted traffic, a first part of the to-be-transmitted traffic for performing a check on the to-be-transmitted traffic according to a check policy, wherein the check policy is for checking access permission of the to-be-transmitted traffic or a forwarding policy of the to-be-transmitted traffic;
- forward, to a destination of the to-be-transmitted traffic after the check passes, the first part;
- and
- transmit to a first forwarding node located on the first forwarding path, a second part of the to-be-transmitted traffic for the first forwarding node to send the second part to the destination based on forwarding indication information,
- wherein the forwarding indication information instructs the first forwarding node to send the to-be-transmitted traffic to the destination.
An access device comprising:
- a memory configured to store program instructions;
- and
- a processor coupled to the memory and configured to execute the program instructions to cause the access device to:
- transmit, to a forwarding controller according to a first forwarding path of to-be-transmitted traffic, a first part of the to-be-transmitted traffic for performing a check on the to-be-transmitted traffic according to a check policy, wherein the check policy is for checking access permission of the to-be-transmitted traffic or a forwarding policy of the to-be-transmitted traffic;
- forward, to a destination of the to-be-transmitted traffic after the check passes, the first part;
- and
- transmit to a first forwarding node located on the first forwarding path, a second part of the to-be-transmitted traffic for the first forwarding node to send the second part to the destination based on forwarding indication information,
- wherein the forwarding indication information instructs the first forwarding node to send the to-be-transmitted traffic to the destination.
A computer program product comprising instructions that are stored on a computer-readable medium and that, when executed by a processor, cause an access device to:
- transmit, to a forwarding controller according to a first forwarding path of to-be-transmitted traffic, a first part of the to-be-transmitted traffic for performing a check on the to-be-transmitted traffic according to a check policy, wherein the check policy is for checking access permission of the to-be-transmitted traffic or a forwarding policy of the to-be-transmitted traffic;
- forward, to a destination of the to-be-transmitted traffic after the check passes, the first part;
- and
- transmit to a first forwarding node located on the first forwarding path, a second part of the to-be-transmitted traffic for the first forwarding node to send the second part to the destination based on forwarding indication information,
- wherein the forwarding indication information instructs the first forwarding node to send the to-be-transmitted traffic to the destination.
