Abstract
A received data stream is formed into a stream of packets, each packet comprising a payload section of data and an overhead section. In forming the packets, a template overhead section is created for use by the stream of packets and this template is applied to the data to form the packets. This avoids the need to individually pass packets through a routing stack, thus reducing the processing demands on the processor which constructs the data packets and reducing the transmission delay experienced by data. The template overhead section can be formed by sending a packet through a routing stack. Another aspect describes apparatus for processing packets where a first processor processes signalling packets and a second processor processes real-time data packets. The first processor can be, used to create the template overhead section before passing the template information to the second processor where it can be used in forming the real-time data packets.
