PLAYOUT BASED DELAY SCHEDULER
First Claim
1. A node of a telecommunications network which receives, over a transmission chain subject to packet jitter, packets of a connection involving a client device, the node comprising:
- a packet buffer configured to store the packets received over the transmission chain prior to transmission of the packets to the client device;
a scheduler configured to schedule the transmission of the packets from the packet buffer over a channel to the client device in accordance with a timing consideration of the client device.

Abstract
A node (22) of a telecommunications network (2) receives, over a transmission chain (24) subject to packet jitter, packets of a connection involving a client device (26). The node (22) comprises a packet buffer (38) configured to store the packets received over the transmission chain prior to transmission of the packets to the client device (26). The node (22) further comprises a client-conscious scheduler (40) which is configured to schedule the transmission of the packets from the packet buffer (38) over a channel (32) to the client device (26) in accordance with a timing consideration of the client device (26). In an example embodiment, the timing consideration of the client device (26) which is taken into account by the scheduler (40) is avoidance of drain of a playout buffer of the client device.
