Consider a diagonal factor block of a supernode
, viewed as a 3-by-3 block matrix with roughly equal block sizes,
One-way key derivation means that each node would generate the succession keys by itself while the supernode
has no need to distribute fresh keys to those members; thus, it can reduce communication rounds in rekeying process.
(58.) Napster employed a supernode
at its main indexing servers.
(91) The Grokster defendants, however, through "supernode
" peer-to-peer software, had completely eliminated the need for a central server.
As mentioned already, there may be situations where the supernode
may produce cascading breakdowns in hubs and nodes directly connected to it, which could eventually bring down a network.
clustered around a single supernode
" (218) to enable network
It uses no more storage than a sparse Cholesky factorization of a positive definite matrix with the same sparsity structure due to restricting the pivoting to interchanges within the diagonal block associated to a single supernode
. The coefficient matrix is perturbed whenever numerically acceptable 1 x 1 and 2 x 2 pivots cannot be found within the diagonal block.
Some topics detailed include scalable supernode
selection in peer-to-peer overlay networks, a packet-level traffic model of Starcraft, a method for P2P file-sharing traffic detection, and a scalable coordination space for decentralized distributed environments.
Another variation on the centralized index is the supernode
Additionally, the process is dynamic; a user's node, the end point, could variably become a "supernode
," which accumulates information from other nodes, automatically, based on resource needs.
In using Grokster's "supernode
" or "FastTrack" technology, originally developed by KaZaa, a person seeking to download a work is connected to the most accessible "supernode
", an individual computer on the network designated as an indexing server.
Telx, New York, N.Y., the first and largest carrier-neutral interconnectivity "SuperNode
" in New York City, is offering RAPID VoIP, the capability to provide Rack, Access, Power, and Instant Delivery to Voice over IP Providers.
