Abstract:
Different services like video-on-demand and Internet Protocol telephony require different paths with different transmission profiles. Known modem systems (1) and aggregators (7) select paths by detecting additional information in packet signals, like in Ethernet the so-called Virtual Local Area Network (VLAN) tags, and in Asynchronous Transfer Mode (ATM) so-called (virtual) path identifiers. This disadvantageous additional information can be avoided by detecting (71) a source/destination address and, in response to said detecting, selecting (72) a transmission profile and, in dependence of said selecting, supplying (70) said packet signal to a path defined by said selected transmission profile. Solely the source/destination address, like a source address and/or a destination address, being Ethernet addresses, Internet Protocol addresses or even port addresses, allow said selecting, which is more efficient. Preferably a first path is an interleaved path for video-on-demand with a lower bit error rate, with a second path being a non-interleaved path with a lower delay for Internet Protocol telephony.
