Publication number: 20170078183Abstract: A novel (software defined network) SDN control plane is introduced having new system capabilities to activate and deactivate controllers in real-time upon automatic measurement of network control traffic and service requirements, and proper controller interactions with network switches as control plane topology changes. Also introduced is a control flow table, which defines the assignment of certain control flows (by originator, location, service type, etc.) to different controllers within the SDN.Type: ApplicationFiled: September 14, 2015Publication date: March 16, 2017Applicant: ARGELA YAZILIM VE BILISIM TEKNOLOJILERI SAN.

Publication number: 20160254984Abstract: Systems and methods are described to dynamically set up and tear down service-enabled flow-paths across multiple SDN domains. An SDN controller of a domain periodically shares with other SDN controllers (of other domains) availability of service-enabled paths (aka, a summarized topology) of its respective network as well as associated service parameters of each path segment using a global nomenclature (aka, a dictionary) with other SDN controllers so as to enable each controller to understand and interpret the shared data in the same manner. Hence, each SDN controller can autonomously construct a complete network graph of available service-enabled paths across many domains. Another feature is the use of summarized (internal) topology of each domain as opposed to just using the peering-link related service information to compute desirable path alternatives.Type: ApplicationFiled: February 27, 2015Publication date: September 1, 2016Inventors: A.

Patent number: 9392432Abstract: A description of an interface and a system/method is provided to combine frequency, time and power domain resource partitioning between neighbor small cells whereby these cells can execute the resource partitioning, without resorting to a centralized management system, simply by periodically sharing topology-related and interference related information with one another. Such a scheme allows resource partitioning to be executed in real-time as more small cells are deployed into the network.Type: GrantFiled: December 17, 2013Date of Patent: July 12, 2016Assignee: ARGELA YAZILIM VE BILISIM TEKNOLOJILERI SAN.

Publication number: 20150312132Abstract: A method to check health of automatically discovered controllers comprises the steps of: (a) a first controller generating a first Controller-Advertisement message carrying the information required to identify and access the first controller when a new switch port becomes active; (b) the first controller sending the generated first Controller-Advertisement to a first switch having the newly activated port; (c) the first controller receiving at least a second Controller-Advertisement message from at least a second controller; (d) the first controller generating a third unsolicited Controller-Advertisement message with its access information to check health of the second controller; (e) the first controller receiving at least a fourth Controller-Advertisement message from the second controller indicating health information of the second controller, wherein the health information is stored in first controller's Controller Information Base (CIB).Type: ApplicationFiled: July 9, 2015Publication date: October 29, 2015Applicant: ARGELA YAZILIM VE BILISIM TEKNOLOJILERI SAN.VE TIC.

Patent number: 9094285Abstract: Controllers in a Software Defined Network (SDN) automatically discover and authenticate each other as part of the control plane operations, without any need for manual configuration of other controllers. The new capability of such controllers is based on Controller-Advertisement messages transferred between controllers in the same or different SDNs. In doing so, multiple controllers can be used for load sharing, improved reliability under failure of a controller by enabling seamless take over and recovery. Moreover, controllers can cooperate to enable end-to-end services to work across multiple SDNs. Controller-Advertisement messages are also used to check the health statuses of discovered controllers in the same or different SDNs.Type: GrantFiled: January 25, 2013Date of Patent: July 28, 2015Assignee: ARGELA YAZILIM VE BILISIM TEKNOLOJILERI SAN.

Patent number: 8234167Abstract: A system and method for an on-line web-based advertiser-broker to subsidize calls of a plurality of VOIP operators' subscribers by showing them video advertisements from a catalogue of advertisements provided by a plurality of advertisers. The advertisement is shown by the advertiser-broker and then the call is transferred to the VoIP operator for call completion. The advertiser-broker provides the clearing-house services between many advertisers and many VoIP operators, subsidizing wholly or partially phone calls of users of VoIP operators by showing them streaming video advertisements of advertisers who pay for the calls. With this new business, phone calls get monetized through advertisers while users pay nothing for phone calls, and VoIP operators do not need to incorporate advertisers to their business.Type: GrantFiled: March 9, 2007Date of Patent: July 31, 2012Assignee: Argela Yazilim ve Bilisim Teknolojileri San. ve Tic.

Patent number: 7948899Abstract: This invention provides for a technique for selectively off-loading traffic from congested sub-regions of a network to more lightly-loaded regions by making use of Multiprotocol Label Switching (MPLS). For each network element, an Interior Gateway Protocol (IGP) routing is employed to provide re-routing and to identify congested links caused by re-routed trunks for each single failure. The re-routed traffic is then analyzed and alternate Label Switched Paths (LSPs) are identified for such traffic trunks so that the traffic is directed to the alternate LSPs during the single failure event.Type: GrantFiled: December 11, 2009Date of Patent: May 24, 2011Assignee: AT&T Intellectual Property II, LPInventors: Angela L.

Publication number: 20090265220Abstract: The present invention is a system and method to enable advertisement subsidized telecommunications services, which can deliver a campaign comprised of multiple advertisements, each advertisement using a different format (text, audio and video), to user's different terminals (cell phone, soft phone, PDA, PC, etc.) by using different telecommunications channels (text message, phone call, multimedia message, ring tone) simultaneously. The system is comprised of three layers: a campaign manager to manage campaign state, a service logic, which determines the user population and the channel best matching each advertisement's content and format, and a channel manager which emulates a confederation of service applications to simultaneously tap into various telecommunications channels through a Service Delivery Platform (SDP), or by directly attaching to the operator's network.Type: ApplicationFiled: March 30, 2009Publication date: October 22, 2009Applicant: ARGELA TECHNOLOGIESInventors: ISMAIL BAYRAKTAR, Seyhan CIVANLAR, Erhan LOKMAN, Oguz OKTAY, Aziz SEVER
