Abstract: Proposed is a method of enabling a packet loss measurement in a network. Via a group of user ports data packets containing a same source address and a same destination address are received. A link aggregation of the group of user ports is performed. At a network port, received data packets are transmitted to a far end network edge node. A number of transmitted data packets is determined, and also for each of the user ports a number of data packets lost internally is determined. At the network port, a corrected number of transmitted data packets is indicated to the far end network edge node as the sum of the determined number of transmitted data packets the overall number of data packets lost internally.

Abstract: A method of processing information packets is disclosed which is adapted for a telecommunication apparatus comprising first processing means, second processing means and memory means. This method comprises the steps of: A) receiving an information packet from a telecommunication network by means of the first processing means; B) checking whether the value of a predetermined characteristic of this packet has already been processed by the second processing means; C) if the check at step B) is negative, checking whether this value has already been stored into the memory means; and D) if the check at step C) is negative, transmitting this value from the first processing means to the memory means and storing this value into the memory means. This method can advantageously be used in a telecommunication apparatus, particularly a layer-2 switch machine.
