| 20090059793 | Traffic engineering method, system and computer program product for managing traffic over dynamic networks during both normal and unexpected traffic scenarios - A network traffic engineering method, system and computer program cope with dynamic and unpredictable changes in traffic demands and in the availability and quality of interdomain routes by monitoring traffic over a network having nodes and links, calculating a routing utilizing a convex-hull-based optimal traffic engineering algorithm with penalty envelope (COPE), and adjusting network traffic flow in accordance with the calculated routing. Aggregating collected historical traffic matrices to produce a predicted traffic matrix, the method optimizes for the expected traffic scenario while providing a worst-case guarantee for unexpected traffic scenarios and thereby advantageously achieves efficient resource utilization during normal traffic and avoids network congestion in a wide variety of scenarios. | 03-05-2009 |
| 20090303880 | DATA CENTER INTERCONNECT AND TRAFFIC ENGINEERING - A system for commoditizing data center networking is disclosed. The system includes an interconnection topology for a data center having a plurality of servers and a plurality of nodes of a network in the data center through which data packets may be routed. The system uses a routing scheme where the routing is oblivious to the traffic pattern between nodes in the network, and wherein the interconnection topology contains a plurality of paths between one or more servers. The multipath routing may be Valiant load balancing. It disaggregates the function of load balancing into a group of regular servers, with the result that load balancing server hardware can be distributed amongst racks in the data center leading to greater agility and less fragmentation. The architecture creates a huge, flexible switching domain, supporting any server/any service, full mesh agility, and unregimented server capacity at low cost. | 12-10-2009 |
| 20090307334 | DATA CENTER WITHOUT STRUCTURAL BOTTLENECKS - A method of networking a plurality of servers together within a data center is disclosed.

The method further includes the steps of obtaining routing information required to route the packet to the destination server. This routing information may be obtained from a directory service servicing the plurality of servers. Once the routing information is obtained, the data packet may be routed to the destination server according to the flat address of the destination server and routing information obtained from the directory service. | 12-10-2009 |

| 20090089438 | INTELLIGENT NETWORK ADDRESS LOOKUP SERVICE - An intelligent lookup service for a network is provided for clients of a network requesting services of the network that intelligently determines, based on a service requirement of the requested service, optimal service endpoint(s) for providing the requested service. The intelligent lookup service can incorporate predetermined mapping policy and traffic measurements into the determination. In addition, a feedback loop is provided from clients and/or service endpoints to the lookup service concerning measurements about prior connections in the network. The lookup service can include a set of beacons distributed in the network and against which measurements about the network are recorded. A client receives, from the lookup service in response to a request for a network address, a set of candidate service endpoints that pertain to the requested network address and the client connects to one of the candidate service endpoints based on policy or context. | 04-02-2009 |
| 20100036903 | DISTRIBUTED LOAD BALANCER - Systems and methods that distribute load balancing functionalities in a data center. A network of demultiplexers and load balancer servers enable a calculated scaling and growth operation, wherein capacity of load balancing operation can be adjusted by changing the number of load balancer servers. Accordingly, load balancing functionality/design can be disaggregated to increase resilience and flexibility for both the load balancing and switching mechanisms of the data center. | 02-11-2010 |
| 20100082804 | MEASURED CLIENT EXPERIENCE FOR COMPUTER NETWORK - Routing network traffic on a computer network is described. In one embodiment, a method is presented which includes transmitting instructions to a client, the instructions executable by the client to request content from two or more content servers, measure two or more network performance characteristics associated with the two or more different content servers, and issue a report to an administrative server. The report may include a first network performance characteristic and a second network performance characteristic. The method may further include selecting a target content server from one of two or more content servers based on comparison of the two or more network performance characteristics; and transmitting routing instructions to an intermediate routing system, the routing instructions executable by the intermediate routing system to direct subsequent content requests transmitted by the client to the target content server. | 04-01-2010 |
| 20100299349 | Reducing Latency in Returning Online Search Results - An embodiment of the invention is directed to reducing search-response latency. The closest intermediate server can be located between a client computing device and a search engine. A search query is sent to the intermediate server in a first packet of a transport protocol handshake. A plurality of packets are received from the intermediate server. The plurality of packets are used to open a window associated with a transport protocol. A response related to the search query is received by the client. | 11-25-2010 |
