The services include a middleware management service that is configured to maintain per-tenant middleware policy for each of multiple tenants. The middleware management service causes the middleware policy to be applied to network traffic by directing network traffic to a middleware enforcement mechanism. This middleware policy is per-tenant in that it depends on an identity of a tenant. | 2016-05-26 |
20160149814 | METHOD AND SYSTEM FOR OPTIMIZING NETWORK TRAFFIC IN A DISTRIBUTED SYSTEM WITH A POINT OF CONVERGENCE - Techniques are disclosed herein for managing network bandwidth in a distributed system having multiple endpoints that upload data to a central server or server cluster. One embodiment provides a computer-implemented method that includes collecting network measurements from traffic flows in a network over which the endpoints upload the data to the central server or server cluster. The method further includes determining a logical topology of the network based on the network measurements, and solving an optimization problem to determine a bandwidth allocation scheme for the endpoints uploading data, wherein capacity of links in the logical topology are constraints in the optimization problem. In addition, the method includes controlling bandwidth consumption by the endpoints based on the determined bandwidth allocation scheme. | 2016-05-26 |
20160149815 | QUALITY OF SERVICE FOR MIXED SERVICE TIERS - Improving the quality of service in multiple service tiers, particularly during periods of Internet congestion, may be accomplished by scaling back the bitrate from a maximum rate to a minimum reserved rate in a non-linear fashion. The use of an intermediate value for scaling back enables a quick drop off of high maximum rates. In embodiments, the shape of a non-linear curve may be configured and controlled to make the drop-off steeper for heavy users. | 2016-05-26 |
20160149816 | Fault Tolerant and Load Balanced Routing - Techniques are described for balancing traffic load for networks configured in multi-rooted tree topologies, in the presence of link failures. Maximum flows (through minimum cuts) are calculated for subgraphs that incorporate effective link capacities on links between source and destination nodes. Effective link capacities may be determined that take into account link failures, as well as sharing of current available link capacities by multiple nodes. Traffic is balanced while simultaneously fully utilizing available link capacities, even available link capacities on partially failed links (e.g., partially failed Link Aggregation Groups (LAGs)). | 2016-05-26 |
