An apparatus in a LAN has first and second hardware interfaces to connect to the LAN. First and second monitoring request messages are transmitted to one or more devices in a first VLAN and one or more devices in a second VLAN respectively, via both the first and second hardware interfaces. The monitoring request messages use the Address Resolution Protocol (ARP) or the Neighbor Discovery Protocol (NDP). First and second monitoring response messages are received via the first and/or second hardware interfaces in response to the first and second monitoring request messages respectively.

A technique for exchanging messages in a computer network using a public data template and a message transfer protocol with interdependent request and confirmation messages is described. A request message includes a first data structure obtained by packing application data that requires confirmation in the public data template. A network component receiving the request message unpacks the application data and provides the unpacked application data to a confirmation process. At the same time, the unpacked application data provided to the confirmation process is repacked in the public data template to generate a second data structure. The second data structure is sent with a confirmation message via the computer network to the sender of the request message. By comparing the content of the first data structure with the content of the second data structure, inconsistencies degrading the accuracy and trustworthiness of the confirmation process may be detected.

The present invention relates to an apparatus and method of frame synchronization in broad band wireless communication systems. In an apparatus of frame synchronization in a mobile station, a time variant phase rotation compensator eliminates time variant phase rotation carried in received signals by conjugated multiplication between adjacent signal samples.

A local power calculator acquires an average power of several symbols centered on delayed correlation values. A normalizer normalizes the delayed correlation values with a local average power corresponding to the delayed correlation values. A maximum value detector selects the maximum value from normalized correlation values to trigger frame synchronizing and timing signals.
