A method for performing a performance measurement on a packet flow transmitted in a communication network, said method comprising: a) alternately transmitting packets of said packet flow on a first connection and second connection set up through said communication network; b) providing a first transmission performance parameter (c1A, t1A) and a second transmission performance parameter (c1B, t1B) relating to said packets as transmitted alternately on said first connection and said second connection, respectively; c) providing a first reception performance parameter (c2A, t2A) and a second reception performance parameter (c2B, t2B) relating to said packets as received alternately from said first connection and said second connection, respectively; and d) providing a performance measurement relating to said packet flow based on said first transmission performance parameter (c1A, t1A) and said first reception performance parameter (c2A, t2A), or based on said second transmission performance parameter (c1B, t1B) and said second reception performance parameter (c2B, t2B), wherein: - said first connection and said second connection are originated by a first originating network point (IN1A) and a second originating network point (IN1B), respectively, and are terminated by a first terminating network point (IN2A) and a second terminating network point (IN2B), respectively; and - step a) comprises periodically switching transmission of said packets between said first originating network point (IN1A) and said second originating network point (IN1B), packets transmitted by said first originating network point (IN1A) and said second originating network point (IN1B) being received at said first terminating network point (IN2A) and said second terminating network point (IN2B), respectively, wherein step a) further comprises: • transmitting the packets of said packet flow received from said first connection (C1A) on a further first connection (C2A) set up through said communication network; and • transmitting the packets of said packet flow received from said second connection (C1B) on a further second connection (C2B) set up through said communication network, wherein said further first connection (C2A) and said further second connection (C2B) are originated by said first terminating network point (IN2A) and said second terminating network point (IN2B), respectively, and are terminated by a further first terminating network point (IN3A) and a further second terminating network point (IN3B), respectively. a) alternately transmitting packets of said packet flow on a first connection and second connection set up through said communication network; b) providing a first transmission performance parameter (c1A, t1A) and a second transmission performance parameter (c1B, t1B) relating to said packets as transmitted alternately on said first connection and said second connection, respectively; c) providing a first reception performance parameter (c2A, t2A) and a second reception performance parameter (c2B, t2B) relating to said packets as received alternately from said first connection and said second connection, respectively; and d) providing a performance measurement relating to said packet flow based on said first transmission performance parameter (c1A, t1A) and said first reception performance parameter (c2A, t2A), or based on said second transmission performance parameter (c1B, t1B) and said second reception performance parameter (c2B, t2B), - said first connection and said second connection are originated by a first originating network point (IN1A) and a second originating network point (IN1B), respectively, and are terminated by a first terminating network point (IN2A) and a second terminating network point (IN2B), respectively; and - step a) comprises periodically switching transmission of said packets between said first originating network point (IN1A) and said second originating network point (IN1B), packets transmitted by said first originating network point (IN1A) and said second originating network point (IN1B) being received at said first terminating network point (IN2A) and said second terminating network point (IN2B), respectively, • transmitting the packets of said packet flow received from said first connection (C1A) on a further first connection (C2A) set up through said communication network; and • transmitting the packets of said packet flow received from said second connection (C1B) on a further second connection (C2B) set up through said communication network,
