Method for providing an elastic content filtering security service in a mesh network
The present disclosure distributes processing capabilities throughout different nodes in a wireless network. Methods and apparatus consistent with the present disclosure increase the efficiency of communications in a wireless network because they help minimize the need to forward communications to other nodes in the network. Apparatus and methods consistent with the present disclosure perform a function of elastic content filtering because rating information may be stored in different memories of different mesh nodes according to rules or profiles associated with a wireless mesh network as responses to requests are sent back along a route in a wireless mesh network in a manner that may not increase an amount of network traffic. When, however, network traffic dips below a threshold level, additional messages may be sent to certain mesh nodes that update rating information stored at those certain mesh nodes.
1. A method for distributing rating information, the method comprising:
storing in memory of a mesh portal device:
routing information that identifies one or more communication routes within a wireless mesh network, each of the communication routes including a set of one or more wireless mesh nodes, and
reputation information that correlates a reputation with a first access request for a website;
transferring the first access request along a first one of the communication routes that includes a first set of one or more wireless mesh nodes, wherein the wireless mesh nodes of the first route store the reputation information in cache memory;
identifying that an amount of communication traffic along the first route has dropped below a threshold level;
determining that the reputation correlated with the first access request is not stored at one or more wireless mesh nodes along a second route; and
transmitting the reputation information to the wireless mesh nodes along the second route when the amount of communication traffic is identified as having dropped below the threshold.
2. The method of claim 1 , further comprising assigning one or more time-to-live (TTL) values for each route based on a number of possible routes for wireless traffic associated with each of the wireless mesh nodes in the route.
3. The method of claim 2 , wherein the TTL values are inversely proportional to the number of possible routes when wireless mesh traffic is evenly distributed between a set of routes that includes the first route and the second route.
4. The method of claim 1 , wherein the wireless mesh nodes along the second route are configured to block access in response to access requests for content associated with a negative reputation.
5. The method of claim 1 , further comprising dynamically increasing wireless network traffic associated with actively transmitting reputation information to one or more wireless mesh nodes along a third route, wherein one or more of the wireless mesh nodes along the third route are known not to store reputation information associated with content previously requested by one or more computing devices in communication with the wireless mesh network.
6. The method of claim 1 , further comprising identifying the amount of communication traffic by determining a number of wireless messages received by the wireless mesh network over a period of time.
7. The method of claim 1 , further comprising:
identifying that the amount of communication traffic through the wireless mesh network exceeds the threshold level along the first route; and
transmitting updated reputation information to the wireless mesh nodes along the second route without increasing the wireless network traffic.
8. A non-transitory computer-readable storage medium having embodied thereon a program executable by a processor to implement a method for distributing rating information, the method comprising:

transferring the first access request along a first one of the communication routes that includes a first set of one or more wireless mesh nodes, wherein the wireless mesh nodes of the first route store the reputation information in cache memory;
identifying that an amount of communication traffic along the first route has dropped below a threshold level;
determining that the reputation correlated with the first access request is not stored at one or more wireless mesh nodes along a second route; and
transmitting the reputation information to the wireless mesh nodes along the second route when the amount of communication traffic is identified as having dropped below the threshold.

The non-transitory computer-readable storage medium of claim 8 , the program further executable to dynamically increase wireless network traffic associated with actively transmitting reputation information to one or more wireless mesh nodes along a third route, wherein one or more of the wireless mesh nodes along the third route are known not to store reputation information associated with content previously requested by one or more computing devices in communication with the wireless mesh network.
13. The non-transitory computer-readable storage medium of claim 8 , the program further executable to identify the amount of communication traffic by determining a number of wireless messages received by the wireless mesh network over a period of time.
14. The non-transitory computer-readable storage medium of claim 8 , the program further executable to:
identify that the amount of communication traffic through the wireless mesh network exceeds the threshold level along the first route; and
transmit updated reputation information to the wireless mesh nodes along the second route without increasing the wireless network traffic.
15. A system for distributing rating information, the system comprising:

identify that an amount of communication traffic along the first route has dropped below a threshold level; and
determine that the reputation correlated with the first access request is not stored at one or more wireless mesh nodes along a second route,
