摘要： A method of preparing packets for injection into a packet network at an ingress interface of the packet network, for transmission over the network. The method comprises, at the ingress interface, receiving at least two parallel, constant bit rate streams of data, and separately packetising the constant bit rate streams to generate respective packet flows for forwarding to a packet sender. The frequency of at least one of the packet flows with respect to another packet flow is set so as to reduce the degree of correlation between the packet flows, and the packet flows sent to the same or different egress interfaces over the packet network.

摘要： A method of recovering a clock signal for a TDM output from packets of TDM data which have been transmitted over a packet network, from a source having a source TDM clock to a destination having a destination TDM clock. The method includes providing at least some packets with a Remote Timestamp representing the state of the source TDM clock when the packet is created; providing said at least some packets with a Local Timestamp representing the state of the destination TDM clock when the packet is received; determining a Transit Time value representing the difference between said Local and Remote Timestamps; and controlling the clock frequency of the TDM output on the basis of said Transit Time as determined above.
