Abstract: This disclosure describes techniques that cause a client device to initiate a policy-pull request to retrieve a policy update associated with the client device. Particularly, a Policy State Propagation (PSP) System may transmit a policy-pull notification to client device that is configured to cause the client device to initiate a request to retrieve the policy update, thereby substantially eliminating a delay between an actual policy update by the telecommunications service provider, and the client device receiving the policy update. The policy update may be based on an update of client profile data or network analytics data associated with operations of the client device on the telecommunications network. Further, the PSP system may generate a policy update data packet that includes the policy update. The PSP system may selectively transmit the policy update data packet to the client device in response receiving the policy-pull request, and further authenticating the client device.

When routing of an IP address in a VPN is to be searched, a Branch_Tree is searched in a Multibit Trie corresponding to the VPN according to the highest m+1 bits of the IP address, and the routing of the IP address is searched in the Branch_Tree.
