Disambiguating conflicting content filter rules
A content filtering mechanism is enhanced to resolve conflicts in filtering rules (e.g., those created by a whitelist, on the one hand, and a blacklist, on the other hand). Preferably, a conflict between or among content filtering rules is resolved by selecting among conflicting rules based on a notion of “risk” associated with the rules. According to this risk-based approach, when two or more rules conflict with one another, the particular rule whose risk value has a predetermined relationship (e.g., aligns most closely) with a risk level associated with the application (applying the rules) then takes precedence. By selecting among conflicting rules based on risk, the potential or actual conflicts are disambiguated, with the result being that the content is filtered appropriately. |

Policy aggregation for computing network health
A network health monitoring application computes aggregate reports of network health by combining status results from a group of segments to render a summary health status indicative of the entire group.

Multiple metrics gathered on each segment allow filtering by polices based on the metric, rather than the attribute (hierarchy level), thus lending a hierarchy filtering based on “vertical” slices of the hierarchy, allowing the user flexibility to filter on specific attribute values while still computing aggregate health at a particular attribute level. |

An aggressor base station (22-1) herein performs downlink interference coordination with one or more victim base stations (22-2, 22-3) in a radio communication network (10). Such coordination is performed for each of one or more iterations. For any given iteration, the aggressor (22-1) sends a message (28-2) to a victim (22-2) that indicates, for each of one or more downlink resources (26), whether the aggressor (22-1) promises to protect that resource (26) from interference by not transmitting on the resource (26) with a transmit power above a threshold (TH2). The victim (22-2) schedules downlink transmissions to one or more user equipments (16) on resources (26) that, according to the message (28-2), are protected from interference. Based on monitoring for interference to those transmissions, though, the victim (22-2) generates and sends to the aggressor (22-1) feedback (30-2) that generally requests an increase or decrease of the threshold (TH2). From evaluation of this feedback (30-2), the aggressor (22-1) determines a new threshold (TH2) on which promises are to be based in a message (28-2) to the victim (22-2) in a subsequent iteration. |
