Abstract
A computer system with black hole management. The black hole management system shares black hole status information among connections that employ the same path. The black hole status information may indicate either that a black hole exists on the path or that communications have been performed successfully on the path, indicating that no black hole exists. By sharing this information, delays in transmission caused by black hole probing may be reduced. Additionally, status information for a connection is reset when information indicates that the connection has been altered. By resetting the status information, delays in transmission associated with sending reduced sized packets over connections for which black holes were previously detected but may have been eliminated by changes in the connection, are avoided.
