Abstract: The invention relates generally to systems, methods and/or devices for joining, generating, maintaining, and/or multicasting information via a multicast mesh.

Abstract: A system tests the protocols for a network containing a group of network devices. The system includes a simulation controller (110) that transmits network configuration information during the protocol testing and one or more nodes (135-1 to 135-N) that emulate a network device, receive the network configuration information from the simulation controller (110), and perform one or more operations in response thereto. The system also includes an analysis device (140) that monitors and analyzes the nodes (135-1 to 135-N) during the protocol testing.

Abstract: A system for exchanging routing information over a communications network constructs a connectivity graph that indicates connectivity between a first node and a first set of nodes in the network. The system constructs an adjacency graph that indicates a second set of nodes with which the first node will exchange routing data, where the adjacency graph is distinct from the connectivity graph. The system exchanges routing data between the first node and each node of the second set of nodes based on the adjacency graph.

Abstract: Micromonospora inyoensis strain 155OF-1G NRRL 5742 is incapable of producing antibiotics unless an aminocyclitol is added to the fermentation medium. When such a compound is added, antibiotics are produced, said antibiotics being analogs of known aminoglycoside antibiotics differing therefrom with respect to the aminocyclitol subunit.
