Publication number: 20110211449Abstract: Methods and apparatus for congestion control in computer networks achieve high burst tolerance, low latency and high throughput with shallow-buffered switches. A method for controlling congestion includes transmitting a set of data packets on a network connection from a first computing device to a second computing device, identifying each data packet in the set of data packets that experienced congestion on the network connection, sending, by the second computing device to the first computing device, a sequence of bits that represents the number of data packets in the set of data packets that were identified as having experienced congestion, and adjusting a rate of transmitting data packets on the network connection based on the sequence of bits sent to the first computing device.Type: ApplicationFiled: February 26, 2010Publication date: September 1, 2011Applicant: Microsoft CorporationInventors: Mohammedreza Alizadeh Attar, Murari Sridharan, Parveen K. Patel, Balaji Prabhakar, David A. Maltz, Jitendra D. Padhye, Albert G. Greenberg

Publication number: 20100318609Abstract: An enterprise namespace may be extended into a cloud of networked resources. A portion of the cloud may be dynamically partitioned, and the extension of the enterprise namespace established within the portion. Cloud resources thus remain as easily accessible to enterprise users as those which are physically located on the enterprise network. Thus, components such as applications, virtual machine instantiations, application states, server states, etc., may be easily migrated between the enterprise network and the cloud.Type: ApplicationFiled: June 15, 2009Publication date: December 16, 2010Applicant: Microsoft CorporationInventors: Parantap Lahiri, Parveen K. Patel, David A. Maltz, Albert Greenberg, Hasan S. Alkhatib, John D. Dunagan

Publication number: 20100257281Abstract: Alternate communication paths may be analyzed and selected for ongoing communications between two devices. One or both of the communicating devices may identify available communication paths and various identifiers on those paths. The identifiers may be, for example, base stations for a wireless connection, beacon signals, or other information that may be received by the device. After comparing the available communication paths to identify one or more alternative paths, the ongoing communications may be transferred to the alternative path. The initial communication path may be used to pass authentication and encryption information that may be used to establish the alternative path between the devices. The redirection of a communication stream may be performed by an interceptor inserted between the application layer and transport layer in a network stack of the communicating devices.Type: ApplicationFiled: April 3, 2009Publication date: October 7, 2010Applicant: Microsoft CorporationInventors: Parveen K. Patel, Jitendra D. Padhye, Ranveer Chandra

Publication number: 20100080144Abstract: Exemplary methods, systems, and computer program products describe selecting a gateway based on health and performance information of a plurality of gateways. The techniques describe gateways advertising health and performance information, computing devices creating a table of this health and performance information, and selecting a gateway using the table. In response to changes in the health and performance information, the computing device may select a different gateway. The process allows network traffic load to be distributed across a plurality of gateways. This process further provides resilience by allowing a plurality of active gateways to substitute for a non-functioning gateway.Type: ApplicationFiled: September 30, 2008Publication date: April 1, 2010Applicant: Microsoft CorporationInventors: Albert Greenberg, David A. Maltz, Parantap Lahiri, Parveen K. Patel, Sudipta Sengupta

Publication number: 20100036903Abstract: 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.Type: ApplicationFiled: August 11, 2008Publication date: February 11, 2010Applicant: MICROSOFT CORPORATIONInventors: Najam Ahmad, Albert Gordon Greenberg, Parantap Lahiri, Dave Maltz, Parveen K. Patel, Sudipta Sengupta, Kushagra V. Vaid

Publication number: 20100036858Abstract: Systems and methods are provided for the management of files across disparate file systems. In an illustrative operation, an exemplary computing environment comprises a file system management module, and an instruction set comprising at least one instruction to instruct the files system management module to manage, monitor, and control the storage/retrieval of a file across two or more disparate file systems operable on the exemplary computing environment managed using a unified name space. Illustratively, a file can be received by the file system management computing application and processed such that the file can be stored/managed (e.g., transparent to a user) on one of the operable two more disparate file systems according to one or more selected criteria. Further, the file system management application can monitor access patterns or attributes for individual files to generate the criteria used when storing/managing files across the two or more disparate files systems.Type: ApplicationFiled: August 6, 2008Publication date: February 11, 2010Applicant: MICROSOFT CORPORATIONInventor: Parveen K. Patel

Publication number: 20090307334Abstract: A method of networking a plurality of servers together within a data center is disclosed. The method includes the step of addressing a data packet for delivery to a destination server by providing the destination server address as a flat address. 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.Type: ApplicationFiled: March 25, 2009Publication date: December 10, 2009Applicant: MICROSOFT CORPORATIONInventors: David A. Maltz, Albert G. Greenberg, Parveen K. Patel, Sudipta Sengupta, Parantap Lahiri

Publication number: 20090303880Abstract: 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.Type: ApplicationFiled: March 25, 2009Publication date: December 10, 2009Applicant: MICROSOFT CORPORATIONInventors: David A. Maltz, Albert G. Greenberg, Parveen K. Patel, Sudipta Sengupta, Parantap Lahiri

Publication number: 20090210519Abstract: Systems and methods that facilitate remote wake up are described that provide for efficient and transparent wake up of target hosts by remote hosts. In various embodiments, a separate address can be used by a target host for wake up network traffic, which is different from a regular address associated with a target host for normal network communications. In addition, the disclosed subject matter facilitates controlling wake up operations according to trust, identity, and/or a wake up policy.Type: ApplicationFiled: February 18, 2008Publication date: August 20, 2009Applicant: MICROSOFT CORPORATIONInventors: Brian Don Zill, David Garfield Thaler, III, Parveen K.
