Publication number: 20140056138Abstract: An example of a method of policing a flow in a home network such as a MoCA network may include calculating a policing period, calculating a first credit parameter, initializing a first usage variable at a beginning of the policing period, receiving a packet at an ingress node, calculating the first usage variable based on a first formula, determining whether the first usage variable is less than or equal to the first credit parameter, and making a reservation request when the first usage variable is less than or equal to the first credit parameter. The reservation request is different from an opportunistic reservation request. Examples of a system and a computer program product having instructions stored in a tangible computer-readable storage medium are also provided.Type: ApplicationFiled: November 5, 2013Publication date: February 27, 2014Applicant: BROADCOM CORPORATIONInventors: Avi KLIGER, Yitshak OHANA, Philippe KLEIN

Patent number: 8660122Abstract: A communication technique facilitates transmission of low rate traffic over communication nodes. The nodes may be, for example, MoCA nodes. The communication happens while keeping the nodes in ultra low power mode. Accordingly, the technique increases the communication capabilities and coverage of networked nodes without impacting the overall power consumption budget. In one implementation, the technique includes encapsulating a datagram into a datagram information element, appending the datagram information element to a discovery request message, and sending the discovery request message to a network controller. The network controller extracts the datagram information element and forwards it (e.g., by broadcasting) to ultra low powered nodes, for example in an admission control frame.Type: GrantFiled: April 3, 2012Date of Patent: February 25, 2014Assignee: Broadcom CorporationInventors: Philippe Klein, Eyal Abrahamov

Publication number: 20140012902Abstract: A mobile device of a user discovers topological information about electronic devices in a premise environment, and shares such information with a media gateway. The media gateway uses the topological information to augment content from a server, such as a web page that supports access to media content, to add graphical objects corresponding to those electronic devices in proximity to the mobile device that are capable of reproducing the streaming media content. Selection of the one of the add-on graphical objects causes delivery of the media content to the corresponding electronic device instead of the display of the mobile device. In this manner, a more natural selection mechanism than that available using conventional pull-down lists of options is provided.Type: ApplicationFiled: September 16, 2013Publication date: January 9, 2014Applicant: Broadcom CorporationInventor: Philippe Klein

Publication number: 20140003331Abstract: A technique to provide distributed wireless extenders over a MoCA specified coaxial cable backbone, in which the extenders function as wireless connection points on a network. The wireless extenders operate with a central access point controller that functions as the access point for the network, in which the extenders provide a plurality of wireless connection points for devices attempting to access the network. In one scheme, the MoCA backbone is used to transfer multimedia data using protocols such as LWAPP and CAPWAP.Type: ApplicationFiled: June 27, 2012Publication date: January 2, 2014Applicant: BROADCOM CORPORATIONInventor: Philippe Klein

Publication number: 20130347043Abstract: Systems and methods for transmitting packets over a network of communication channels are provide. A system according to the invention may include first and second nodes in communication with a coax backbone. The first node may further include a retransmission buffer. The system may also include a network access coordinator operative to coordinate access of the nodes to the coax backbone. In a time period at least one first packet is transmitted by the first node to the second node. The first packet may include an indication that retransmission service is applied. The first packet may also include a indication of the length corresponding to the packet. If, during the first time period the packet is not received by the second node, the second node is operative to send a retransmission request to the network access coordinator.Type: ApplicationFiled: September 4, 2013Publication date: December 26, 2013Applicant: Broadcom CorporationInventors: Yitshak OHANA, Philippe Klein, Avi Kliger

Patent number: 8611327Abstract: Systems and methods for policing a Quality of Service (QoS) flow in a MoCA network are provided. The network may include a sending node, a receiving node and a network controller. The network controller may allocate a QoS flow between the sending node and the receiving node. The sending node may request bandwidth for the QoS flow from the network controller. QoS requests have a higher priority than some other requests and may swamp the network. The sending node therefore polices its use of the network. First, the sending node computes a policing time period Tpp. Next the sending node computes a packet and bit allocation for the use of the network during a Tpp. Last the sending node sends reservation requests to the network controller when the allocation of packet or bits has not been exceeded. If any allocation has been exceeded the sending node reserves bandwidth via opportunistic reservation requests which have a lower priority than some other requests.Type: GrantFiled: February 22, 2011Date of Patent: December 17, 2013Assignee: Broadcom CorporationInventors: Avi Kliger, Yitshak Ohana, Philippe Klein
