Distributing an advertisement of channel assignments in a wireless mesh network over a sequence of multiple advertisement elements
According to the known IEEE 802.11s Draft Standard for WLAN Mesh Networking, version D5.0, the size of an information element is restricted to a length of 255 octets. Due to the definition of an MCCAOP advertisements element as a general information element this restriction is a major drawback leading to a maximum of 62 MCCA reservations to be advertised by an MCCAOP advertisements element. Although this number of reservations might be sufficient in the majority of situations, it is easily imaginable that there are situations which could require an advertisement exceeding this limit of 62 MCCA reservations. According to the disclosure, an MCCAOP advertisement—which is a set of MCCAOP reservations that needs to be advertised—is split over multiple MCCAOP advertisements elements. This may advantageously allow advertising more than 62 MCCAOP reservations to neighboring mesh nodes in a wireless mesh network which is configured to use MCCA. |

Broadcast based discovery of Wi-Fi networks, devices and services
Embodiments reduce the time and energy expended to establish an initial link to a network. Some embodiments use either active or passive scans to discover available access points and then use a broadcast or multicast Generic Advertisement Service (GAS) Request message to identify access points providing requested services. Other embodiments use a broadcast or multicast GAS Request message to identify access points or mobile devices providing requested services without first scanning for access points. Only access points or mobile devices providing requested services need to respond to the GAS request message. Duplicate messages received by multiple access points coupled to the same network can be filtered so only one message is received and responded to. |

Reliability and availability of distributed servers
A system of network proxies distributes data to multiple servers. Each network proxy is associated with a server. A network proxy intercepts a client request for data. If the network proxy determines that the request can be served using a copy of data stored on the local server, rather than the data stored on a remote server, it diverts the request to the local server. If the network proxy determines that the request cannot be served using a data from the local server, the network proxy diverts the request to a remote server storing the primary copy of the data. A server map specifies the locations of the primary copies of data. When a primary copy of data is updated on one of the servers, the associated network proxy propagates the updated data to the other servers. The servers can provide data from files, e-mail services, databases, or multimedia services. |

Switch system, and data forwarding method
The upper limit of the number of the flow entries subjected to retrieval is increased by making it possible to retrieve the flow entries in plural switches for one communication data. Specifically, the control server registers flow entries by distributing them to the flow table in each switch belonging to a switch group. When acquiring the communication data, each switch checks whether the communication data is matched with any of the flow entries registered in the flow table. When the communication data is matched with a flow entry, the communication data is forwarded based on the forwarding procedure defined in the flow entry. When the communication data is not matched with any flow entry, the communication data is forwarded to “flow table unretrieved switch” belonging to the same switch group. When there is no flow table unretrieved switch, a query of the forwarding procedure is performed to the control server. |

Bonded structures for package and substrate
The embodiments described provide elongated bonded structures near edges of packaged structures free of solder wetting on sides of copper posts substantially facing the center of the packaged structures. Solder wetting occurs on other sides of copper posts of these bonded structures. The elongated bonded structures are arranged in different arrangements and reduce the chance of shorting between neighboring bonded structures. In addition, the elongated bonded structures improve the reliability performance. |
