Abstract: Disclosed is an improved implementation of a flood fill mesh network that utilizes low power and does not require any network addressing or routing protocol for network message delivery. Network messages are only communicated to a network node's correspondents using broadcast network messages over a wireless network. Network messages propagate throughout the network based on each correspondent node rebroadcasting received messages to its correspondent nodes, and so on. Coordinated synchronization across network nodes can be achieved by each network node broadcasting synchronization frames to its correspondents within a synchronization window time period and thereafter adjusting its own start time for the next synchronization period to converge synchronization. A guard band may also be utilized to account for any clock drift and signal path delays between any two communicating network nodes.

The system of some embodiments allows a network administrator to retrieve a total packet count and byte count for one or more logical ports of the logical forwarding element, even though the logical ports may be distributed across multiple physical forwarding elements.

Abstract: A contending radio node is configured for attempting contention-based random access. The contending radio node obtains a timing advance sequence that is susceptible to contention. The contending radio node transmits, using the same transmission advancement timing, the timing advance sequence and a contention-resolving identity to a recipient radio node. Responsive to that transmission, the contending radio node receives a response signal that indicates a contention-resolving identity and a timing advance. The contending radio node resolves any contention in its favor when the contention-resolving identity indicated by the response signal corresponds to the contention-resolving identity that the contending radio node transmitted. The contending radio node, responsive to resolving the contention in its favor, adjusts its transmission advancement timing according to the timing advance indicated by the response signal.
