Systems and methods are provided for determining an optical bypass for an inter-regional wide area network (WAN) for regions of server facilities of a cloud service provider. In particular, the optical bypass connects non-adjacent regional server centers of the WAN by eliminating needs of data conversions at intermediate regional server centers. The determining the optical bypass includes receiving a WAN topology data, capacity and demand information about the WAN. The determining includes an objective function to maximize a number of network resources to free up by determining a revised data flow and bandwidth allocations by introducing the optical bypass in the WAN. The disclosed technology transmits the determined data traffic flow and resource allocation information of the optical bypass, causing a network traffic enforcers to reconfigure the WAN.

Methods for capacity provisioning in wide area networks using optical bypassing

A policy management system is described herein which generates rules based, at least in part, on reputation information provided by at least one reputation source and client event information forwarded by filtering logic. The policy management system then deploys the rules to the filtering logic. The filtering logic, which resides in-network between clients and at least one service, uses the rules to process client event information sent by the clients to the service(s). In one illustrative environment, the service corresponds to an ad hosting service, which uses the policy management system and filtering logic to help prevent malicious client traffic from reaching the ad host service, or otherwise negatively affecting the ad hosting service.
