Two identical satellites were ordered on 1992 from Space Systems Loral, N-STAR a and N-STAR b, for 1995 and 1996 on orbit delivery. [8] [9] They would be "switchboards in the sky" having S-band, C-band, Ka-band and Ku-band payload. [10] N-STAR a was successfully launched aboard an Ariane 44P on 29 August 1995. Its twin, N-STAR b, launched on 5 ...
Short routes between close start and target locations may not require any transit nodes. In this case, the above framework leads to incorrect distances because it forces routes to visit at least one transit node. To prevent this kind of problem, a locality filter can be used. For given start and target locations, the locality filter decides, if ...
The letter "S" indicates that the route is a static route that has, for all intents and purposes, been added manually to the router process by the administrator and installed into the routing table.

Route assignment, route choice, or traffic assignment concerns the selection of routes (alternatively called paths) between origins and destinations in transportation networks. It is the fourth step in the conventional transportation forecasting model, following trip generation , trip distribution , and mode choice .
The specific characteristics of routing protocols include the manner in which they avoid routing loops, the manner in which they select preferred routes, using information about hop costs, the time they require to reach routing convergence, their scalability, and other factors such as relay multiplexing and cloud access framework parameters.
In other words if A learns from B that the path to C is through B then it will not tell B to route packets destined for C through A. Likewise, a link-state routing protocol may keep a database containing the state of different links in the network, representing a "map" (so to speak) of the network. But the portion of the network whose routes ...
On the surface, this seems redundant since B will never route via node A because the route costs more than the direct route from B to C. However, if the link between B and C goes down, and B had received a route from A to C, B could end up using that route via A. A would send the packet right back to B, creating a loop. This is the Count to ...
N-STAR c, is a geostationary communications satellite originally ordered by NTT DoCoMo and later fully acquired by SKY Perfect JSAT Group. [5] [6] It was designed and manufactured by Lockheed Martin, which acted as prime, developed the payload and did the final integration and testing, and Orbital Sciences Corporation, which supplied the satellite bus on the GEOStar-2 platform and procured the ...
