Abstract

A first server device may receive, from a second server device, a unique identifier (ID) relates to content stored by the second server device; determine a policy based on the unique ID; generate a policy tag identifying the determined policy; and output the policy tag to the second server device. Outputting the policy tag may cause the second server device to apply the policy tag to a packet associated with the content, and output the packet towards a requesting user device that requests the content.

Claims

1. A network device, comprising:

a non-transitory memory device storing;

a plurality of processor-executable instructions; and

a processor configured to execute the processor-executable instructions, wherein executing the processor-executable instructions causes the network device to;

receive a packet destined for a requesting user device;

determine whether the packet includes a tag;

determine, when the packet includes the tag, a policy associated with the tag;

inspect contents of the packet when the packet is not tagged;

determine the policy based on the contents of the packet; and

output the packet towards the requesting user device in accordance with the determined policy.

2. The network device of claim 1, wherein the tag includes a hash value,

wherein executing the processor-executable instructions, to determine the policy, causes the network device to determine the policy corresponding to hash value.

3. The network device of claim 1, wherein the policy relates to at least one of:

a Quality of Service (QoS) policy,

a QoS Class Indicator (QCI), or

a priority value for a packet queuing algorithm.

4. The network device of claim 1, wherein the packet includes encrypted content when packet is tagged.

6. A first server device, comprising:

a non-transitory memory device storing;

a plurality of processor-executable instructions; and

a processor configured to execute the processor-executable instructions, wherein executing the processor-executable instructions causes the first server device to;

receive, from a second server device, a unique identifier (ID) relates to content stored by the second server device;

determine a policy based on the unique ID;

generate a policy tag identifying the determined policy; and

output the policy tag to the second server device,

wherein outputting the policy tag causes the second server device to apply the policy tag to a packet associated with the content, and output the packet towards a requesting user device that requests the content.

7. The first server device of claim 6, the policy tag, outputted to the second server device, causes a network device to determine the policy associated with the tag, and output the packet towards the requesting user device in accordance with the determined policy.

8. The first server device of claim 6, wherein the policy relates to at least one of:

a Quality of Service (QoS) policy,

a QoS Class Indicator (QCI), or

a priority value for a packet queuing algorithm.

9. The first server device of claim 6, wherein executing the processor-executable instruction, to determine the policy, causes the first server device to determine the policy without inspecting the content.

10. The first server device of claim 6, wherein executing the processor-executable instruction, to generate the tag, causes the first server device to generate a hash value corresponding to the tag.

11. The first server device of claim 6, wherein executing the processor-executable instruction, to determine the policy, causes the first server device to determine attributes of the content based on the unique ID, and determine the policy based on the attributes.

12. The first server device of claim 6, wherein the content includes encrypted content.

13. The first server device of claim 6, wherein the unique ID further relates to information regarding the requesting user device.

14. A method comprising:

receiving, by a first server device and from a second server device, a unique identifier (ID) relates to content stored by the second server device;

determining, by the first server device, a policy based on the unique ID;

generating, by the first server device, a policy tag identifying the determined policy; and

outputting, by the first server device, the policy tag to the second server device,

wherein outputting the policy tag causes the second server device to apply the policy tag to a packet associated with the content, and output the packet towards a requesting user device that requests the content.

5. The method of claim 17, wherein the policy is determined without performing deep packet inspection (DPI) for the packet.

15. The method of claim 14, wherein outputting the policy tag to the second server device causes a network device to determine the policy associated with the tag, and output the packet towards the requesting user device in accordance with the determined policy.

16. The method of claim 14, wherein the policy relates to at least one of:

a Quality of Service (QoS) policy,

a QoS Class Indicator (QCI), or

a priority value for a packet queuing algorithm.

17. The method of claim 14, wherein determining the policy includes determining the policy without inspecting the content.

18. The method of claim 14, wherein generating the tag includes generating a hash value corresponding to the tag.

19. The method of claim 14, wherein determining the policy further includes determining attributes of the content based on the unique ID, and determining the policy based on the attributes.

20. The method of claim 14, wherein the content includes encrypted content.
