摘要： A method and apparatus are described including performing hop-by-hop multicasting including network coding of data packets of a portion of content, wherein network coding further includes encoding data packets of a portion of content, multicasting said network coded data packets to downstream receivers, determining if an acknowledgement message has been received from at least one of the downstream receivers, determining if acknowledgement messages have been received from all of the downstream receivers responsive to the first determination.

摘要： The present invention discloses an improved method of combination test by using argon as gross-leak tracer gas and using helium as fine-leak tracer gas, belongs to the field of hermeticity test. The method is designed to solve the problem that the existing methods are not ideal when the component has lower τHemin and wider range of volume V. The invention comprises step S1 of selecting: using helium-argon prefilling method for the first hermeticity test and helium-argon pressuring method after helium-argon prefilling for repetitive hermeticity test, or using helium-argon pressuring method after argon prefilling for the first hermeticity test and helium-argon multi-pressuring method after argon prefilling for repetitive hermeticity tests. The improved method extends the maximum detection-waiting time, effectively prevents detection missing and misjudges in gross-leak/fine-leak test, and solves the detection problems on applicability, feasibility and credibility.
