Publication number: 20180167300Abstract: This document relates to a distributed network coordinate system. One implementation provides computer-readable storage media including instructions that may cause a processor to perform certain acts. For example, the acts may include storing an initial network location of a first device in a network. The network may include the first device and a second device. The acts may also include monitoring one or more network performance metrics related to existing application communications with the second device, and determining an updated network location of the first device, based on the initial network location and the network performance metrics. Aspects of network health can be derived from monitoring changes in the network locations of various devices within the coordinate system.Type: ApplicationFiled: December 11, 2017Publication date: June 14, 2018Inventors: Lihua YUAN, Sharad AGARWAL, Kevin DAMOUR, Thekkthalackal Varugis KURIEN, Albert G.

Patent number: 9537773Abstract: The ensuring of predictable and quantifiable networking performance. Embodiments of the invention combine a congestion free network core with a hypervisor based (i.e., edge-based) throttling design to help insure quantitative and invariable subscription bandwidth rates. A lightweight shim layer in a hypervisor can adaptively throttle the rate of VM-to-VM traffic flow. A receiving hypervisor can detect congestion and communicate back to sending hypervisors that rates are to be regulated. In response, sending hypervisors can reduce transmission rate to mitigate congestion at the receiving hypervisor. In some embodiments, the principles are extended to any message processors communicating over a congestion free network.Type: GrantFiled: December 29, 2015Date of Patent: January 3, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Changhoon Kim, Albert G.

Patent number: 9049140Abstract: A source device obtains a data packet that includes both a destination address and a payload. The source device selects an exit point address of multiple exit point addresses corresponding to the destination address based on one or more policies. The source device encapsulates the data packet with a header that includes the selected exit point address, and the encapsulated data packet is provided to the backbone network. The encapsulated data packet is routed through the backbone network based on the exit point address, and an edge router of the backbone network identifies an interface of the edge router that corresponds to the exit point address. The header is removed from the encapsulated data packet, and the data packet is added to a buffer of the interface for routing to one or more other devices outside of the backbone network.Type: GrantFiled: November 18, 2010Date of Patent: June 2, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Abhishek Singh, Ming Zhang, Albert G.

Patent number: 9001663Abstract: 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: GrantFiled: February 26, 2010Date of Patent: April 7, 2015Assignee: Microsoft CorporationInventors: Mohammedreza Alizadeh Attar, Murari Sridharan, Parveen K.

Patent number: 8996683Abstract: 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: GrantFiled: March 25, 2009Date of Patent: March 31, 2015Assignee: Microsoft Technology Licensing, LLCInventors: David A.

Patent number: 8856518Abstract: Techniques for efficient and secure implementation of network policies in a network interface controller (NIC) in a host computing device operating a virtualized computing environment. In some embodiments, the NIC may process and forward packets directly to their destinations, bypassing a parent partition of the host computing device. In particular, in some embodiments, the NIC may store network policy information to process and forward packets directly to a virtual machine (VM). If the NIC is unable to process a packet, then the NIC may forward the packet to the parent partition. In some embodiments, the NIC may use an encapsulation protocol to transmit address information in packet headers. In some embodiments, this address information may be communicated by the MC to the parent partition via a secure channel. The NIC may also obtain, and decrypt, encrypted addresses from the VMs for routing packets, bypassing the parent partition.Type: GrantFiled: August 2, 2012Date of Patent: October 7, 2014Assignee: Microsoft CorporationInventors: Murari Sridharan, Narasimhan Venkataramaiah, Yu-Shun Wang, Albert G.

Patent number: 8824461Abstract: Method and apparatus for providing a control plane across multiple optical network domains is described. In one example, topology and resource discovery is employed in a transport network having a plurality of control domains. Topology information for each of the control domains is summarized to produce summarized topology information. The summarized topology information for each of the control domains is exchanged among the control domains. At each of the control domains, the summarized topology information of each of the control domains is combined to produce combined topology information. The combined topology information is passed among network elements within each of the control domains using an intra-domain routing protocol.Type: GrantFiled: June 17, 2013Date of Patent: September 2, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: Robert Doverspike, Albert G.

Publication number: 20130346465Abstract: A management service that receives requests for the cloud computing environment to host applications, and improves performance of the application using an edge server. In response to the original request, the management service allocates the application to run on an origin data center, evaluates the application by evaluating at least one of the application properties designated by an application code author or provider, or the application performance, and uses an edge server to improve performance of the application in response to evaluating the application. For instance, a portion of application code may be offloaded to run on the edge data center, a portion of application data may be cached at the edge data center, or the edge server may add functionality to the application.Type: ApplicationFiled: June 21, 2012Publication date: December 26, 2013Applicant: MICROSOFT CORPORATIONInventors: David A.
