Patent number: 9118687Abstract: In some embodiments, an apparatus comprises a core network node configured to be operatively coupled to a set of network nodes. The core network node is configured to receive a broadcast signal from a network node from the set of network nodes, which is originated from a host device operatively coupled to the network node. The broadcast signal is sent via a tunnel from the network node to the core network node, such that other network nodes that are not included in the tunnel do not receive the broadcast signal. The core network node is configured to retrieve control information associated with the broadcast signal without sending another broadcast signal, and then send the control information to the network node.Type: GrantFiled: October 4, 2011Date of Patent: August 25, 2015Assignee: Juniper Networks, Inc.Inventors: James Murphy, Nischal Sheth, Abhijit Choudhury, Raghavendra Mallya, Pranay Pogde, Phalguni Nanda, Jayabharat Boddu, Pradeep Sindhu

Patent number: 9106581Abstract: In general, this disclosure describes a high-level forwarding path description language (FPDL) for describing internal forwarding paths within a network device. The FPDL enables developers to create a template that describes a section of an internal forwarding path within the forwarding plane of a network device. The FPDL provides syntactical elements for specifying the allocation of forwarding path structures as well as enabling the run-time construction of internal forwarding paths to interconnect the forwarding path structures in a manner specific to packet, packet flow, and/or interface properties, for example. In conjunction with late binding techniques, whereby the control plane of the network device provides arguments to template parameters that drive allocation by the packet forwarding engines of forwarding path structures specified by the FPDL, the techniques provide control plane processes a unified interface with which to manage the operation of the packet forwarding engines.Type: GrantFiled: August 11, 2014Date of Patent: August 11, 2015Assignee: Juniper Networks, Inc.Inventors: Scott Mackie, James Washburn, Nitin Kumar, Sandeep Bajaj

Patent number: 9049247Abstract: A proxy server receives from a client device a request for a network resource that is hosted at an origin server for a domain. The request is received at the proxy server as a result of a DNS request for the domain resolving to the proxy server. The origin server is one of multiple origin servers that belong to different domains that resolve to the proxy server and are owned by different entities. The proxy server transmits the request to the origin server. Responsive to determining that the origin server is offline, the proxy server determines whether the requested resource is available in cache. If it is in cache, the proxy server retrieves the requested resource from the cache and transmits the requested resource to the client device.Type: GrantFiled: November 4, 2010Date of Patent: June 2, 2015Assignee: CLOUDFARE, INC.Inventors: Lee Hahn Holloway, Matthew Browning Prince

Patent number: 9001675Abstract: Exemplary embodiments increase reliability of communication over a non-deterministic communication channel, in electric power systems. A communication channel is monitored based on regular network traffic, by evaluating messages or data packets carrying real-time operational data as a payload. A permanent determination of a channel quality, including appropriate alarming in case the channel quality is found insufficient, is based on an evaluation, at a receiving node, of data packets continually transmitted by a sending node. These continually or repeatedly transmitted data packets can include identical payloads reflecting current states rather than state changes as operational data.Type: GrantFiled: July 13, 2011Date of Patent: April 7, 2015Assignee: ABB Technology AGInventors: Wolfgang Wimmer, Hubert Kirrmann, Hermann Spiess, Stefan Ramseier, Allen Notter, Martin Israel
