Patent number: 10848338Abstract: Systems and methods relating to a smart home system and, in particular, a manager for a smart home system are disclosed. In some embodiments, a method of operation of a manager of a smart home comprises receiving a resource request from a smart home appliance for a resource of the smart home. The resource request comprises information indicative of a resource bandwidth being requested by the smart home appliance and information indicative of a duration of time for which the resource bandwidth is being requested. The method further comprises scheduling the request based on the resource bandwidth being requested by the smart home appliance, the duration of time for which the resource bandwidth is being requested, and a total resource bandwidth limit for the smart home for the resource requested via the resource request and sending a confirmation of a resource allocation from the manager to the smart home appliance.Type: GrantFiled: November 11, 2015Date of Patent: November 24, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Reza Farrahi Moghaddam, Yves Lemieux, Mohamed Cheriet

Patent number: 10439984Abstract: Providing security for one or more network flows may include a security deployment node decomposing one or more virtual security appliances (265) of a logical security architecture (255) into security modules (310). The security deployment node orders the security modules (310) into a sequence (320) that implements a selected workflow pattern (400). The selected workflow pattern (400) may be selected from a workflow pattern database, and may define the security to be provided for a flow, for example, according to known best practices. The sequence (320) is then divided into segments (330), and the segments (330) are assigned to different groups (220) of network nodes (230) in a network (200). For each segment (330), an assignment of each security module (310) in the segment (330) to a network node (230) within the group (220) to which the segment (330) is assigned is computed. The network (200) is then configured according to the assignments.Type: GrantFiled: February 20, 2015Date of Patent: October 8, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Yosr Jarraya, Alireza Shameli-Sendi, Mohamed Fekih-Ahmed, Makan Pourzandi, Mohamed Cheriet

Patent number: 9912582Abstract: Systems and methods for ensuring multi-tenant isolation in a data center are provided. A switch, or virtualized switch, can be used to de-multiplex incoming traffic between a number of data centers tenants and to direct traffic to the appropriate virtual slice for an identified tenant. The switch can store tenant identifying information received from a master controller and packet forwarding rules received from at least one tenant controller. The packet handling rules are associated with a specific tenant and can be used to forward traffic to its destination.Type: GrantFiled: November 18, 2014Date of Patent: March 6, 2018Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Makan Pourzandi, Mohamed Fekih Ahmed, Mohamed Cheriet, Chamseddine Talhi

Publication number: 20150172115Abstract: Systems and methods for assigning virtualized network elements to physical resources in a cloud computing environment are provided. A resource request is received as input indicating a required number of virtual machines and a set of virtual flows, each of the virtual flows indicating a connection between two virtual machines which need to communicate with one another. Each of the requested virtual machines is assigned to a physical server. The set of virtual flows can be modified to remove any virtual flow connecting virtual machines which have been assigned to the same physical server. Each of the virtual flows in the modified set is assigned to a physical link. If a bandwidth capacity of a requested virtual flow is greater than the available bandwidth of a single physical link between servers, multiple links can be allocated to the virtual flow.Type: ApplicationFiled: December 18, 2013Publication date: June 18, 2015Applicant: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Kim Khoa Nguyen, Mohamed Cheriet, Yves Lemieux

Publication number: 20040204880Abstract: A method and a system for measuring the energy of a signal is based on the use of a time-frequency distribution using as kernel a bi-dimensional filter having compact support properties. The two-dimentional filter is applied to the two-dimensional correlation function of the signal to be analyzed. The system includes an acquisition unit for providing samples of the signal, a Hilbert transformer for producing an alytical signals from those samples, and a local correlator for computing the convolutions of a kernel derived from a Gaussian kernel and having compact support properties and instantaneous autocorrelation functions so as to yield generalized instantaneous autocorrelation functions, and a Fourier transformer for determining information related to the energy of the signal from the derived generalized instantaneous autocorrelation functions. The method and system allows a better reduction of false energy observances (interference) while providing good resolution in time and in frequency.Type: ApplicationFiled: April 29, 2004Publication date: October 14, 2004Inventors: Mohamed Cheriet, Adel Belouchrani
