Abstract
A method, apparatus and system are disclosed that more efficiently maps data into standard SONET concatenated payloads for transmission over established SONET networks. Framing information is added to a data stream to identify the beginning and ending locations of a payload. Next, the framed data stream is formatted into a non-standard STS-Nc packet. Two or more non-standard STS-Nc packets are combined to form a pseudo-standard STS-Nc packet that is supported by the established SONET network. According to one embodiment, a one Gbps Ethernet packet is framed using HDLC formatting, then formatted into an STS-24packet. Two STS-24packets are combined to form a pseudo-standard STS-48packet. In addition, the one Gbps Ethernet packet can be stored and retimed to the SONET data rate and transmitted across an established SONET network.
