Transition detecting method for two states of communication network, involves determining transition probability, and determining transition existence according to transition probability

摘要

The method involves determining a transition probability, and determining transition existence according to the transition probability. The transition probability determination is carried out by detecting lost packets among transmitted data packets, determining distances representing gaps between the sequence number of lost packets, and calculating the transition probability between two sets of distances from the determined distances. Independent claims are also included for the following: (1) a method for protecting data against loss during transmission of data on a communication network (2) a device for detecting transition between two states of a communication network corresponding to different loss rates of transmitted data (3) a device for protecting data against loss during transmission of data on a communication network (4) a computer program comprising a set of instructions for implementing a method for detecting transition between two states of a communication network corresponding to different loss rates of transmitted data and a method for protecting data against loss during transmission of data on a communication network (5) a computer- or microprocessor-readable information medium comprising a set of instructions for implementing a method for detecting transition between two states of a communication network corresponding to different loss rates of transmitted data and a method for protecting data against loss during transmission of data on a communication network.
