Problems solved by technology

However, current SONET infrastructure has not kept pace with this rapid information technology shift and, as a result, network throughput is slowing down significantly due to increased traffic load.
Carriers that operate SONET-based metropolitan area networks (MANs) are especially impacted by this growing congestion.
Besides these limitations, current SONET equipment does not support non-voice digital data such as Ethernet traffic, local area network (LAN) traffic, asynchronous transfer mode (ATM) traffic, frame relay (FR) traffic, Internet Protocol (IP) traffic.
Further, traditional SONET signals are inefficient when carrying non-voice data signals.
The following table describes SONET inefficiencies when carrying Ethernet signals; however, other

Abstract

Network data is received in a first format. The data is converted to a synchronous optical network (SONET) format. Switching functions are performed on the SONET formatted data. The SONET formatted data is converted to a second format. In one embodiment, the switching functions on the SONET formatted data contains performing time switching and space switching.
