Patent number: 9847942Abstract: Load balancing and overload control techniques are disclosed for use in a SIP-based network or other type of network comprising a plurality of servers. In a load balancing technique, a first server receives feedback information from at least first and second downstream servers associated with respective first and second paths between the first server and a target server, the feedback information comprising congestion measures for the respective downstream servers. The first server dynamically adjusts a message routing process based on the received feedback information to compensate for imbalance among the congestion measures of the downstream servers. In an overload control technique, the first server utilizes feedback information received from at least one downstream server to generate a blocking message for delivery to a user agent.Type: GrantFiled: November 12, 2015Date of Patent: December 19, 2017Assignee: WSOU Investments, LLCInventors: Volker Hilt, Indra Widjaja

Patent number: 9386093Abstract: A method and apparatus for peer-to-peer file sharing is provided. In some embodiments, the method includes receiving a request for a list of neighbor peers, where the request is made by a requesting peer device, and where the requesting peer device has a local internet service provider (ISP). The method may also include employing a server device to rank each neighbor peer in a plurality of neighbor peers based on whether the respective neighbor peer is external to the local ISP, and if the respective neighbor peer is external to the ISP, further based on a cost metric associated with a next ISP hop from the requesting peer device to the respective neighbor peer. The method may also include generating the list of neighbor peers based on the ranking of the neighbor peers, and enabling transmission of the list of neighbor peers to the requesting peer device.Type: GrantFiled: February 17, 2010Date of Patent: July 5, 2016Assignee: DEUTSCHE TELEKOM AGInventors: Volker Hilt, Ivica Rimac, Srinivasan Seetharaman

Publication number: 20160026514Abstract: A capability for supporting an elastic virtualized component that is stateful is provided by supporting state migration for the elastic virtualized component. The elastic virtualized component may support a virtualized network function or any other suitable virtualized function. The elastic virtualized component includes a component load balancer and a set of component instances configured to provide functions of the elastic virtualized component. The elastic virtualized component may be configured to support migration of state information of the component instances following elasticity events in which the capacity of the elastic virtualized component changes (e.g., in response to growth events in which the number of component instances of which the elastic virtualized component is composed increases, in response to degrowth events in which the number of component instances of which the elastic virtualized component is composed decreases, or the like).Type: ApplicationFiled: July 23, 2014Publication date: January 28, 2016Applicant: ALCATEL LUCENTInventors: Tommaso Cucinotta, Andrea Meroni, Volker Hilt

Patent number: 9075660Abstract: A capability is provided for improving service availability experienced by a user requesting access to a service via a user device, where the service has multiple service instances available from multiple data centers. A set of servicing data centers is selected for the user device. The set of servicing data centers is selected from a set of candidate data centers. The set of servicing data centers is selected from the set of candidate data centers in a manner for maximizing the independence/orthogonality of the network paths between the user device and the servicing data centers. The set of servicing data centers includes two or more of the candidate data centers from which the user device may access the service, thereby providing the user device with a primary service instance and one or more backup service instances which may be used to access the service.Type: GrantFiled: March 29, 2012Date of Patent: July 7, 2015Assignee: Alcatel LucentInventors: Yang Guo, Eric J.

Patent number: 8539099Abstract: In one embodiment, the method includes receiving a content request from the end user at a proxy. A modified TCP connection request message is generated such that the modified TCP connection request message includes a content identifier. The content identifier identifies the requested content. The modified TCP connection request message is sent from the proxy towards an origin server associated with the requested content, and a response to the TCP connection request message is received from a network element. A TCP connection is established with the network element.Type: GrantFiled: January 8, 2010Date of Patent: September 17, 2013Assignee: Alcatel LucentInventors: Volker Hilt, Ivica Rimac, Suman Srinivasan, Moritz Steiner

Patent number: 8443052Abstract: A content distribution network (CDN) comprising a hierarchy of content storage nodes (CSNs) or caches having storage space that is allocated between local space for storing locally popular content objects and federated space for storing a portion of the less popular content objects. Local space and federated space based upon changes in content object popularity and/or other utility factors. Optionally, parent/child (upstream/downstream) communication paths are used to migrate content between CSNs or caches of the same or different hierarchical levels to avoid utilizing higher price top hierarchical level communications channels.Type: GrantFiled: September 11, 2012Date of Patent: May 14, 2013Assignee: Alcatel LucentInventors: Jairo O.
