2NETWORKING AND ADVANCE DATA COMMUNICATIONSSONETSynchronous Optical Networking is one of the standard multiplexing tools and is usedfor the communication purpose, The SONET utilises the optical fibre medium to transmitdigital data bit stream over the light emitting diodes. This multiplexing protocol isresponsible to deliver the real-time data transfer as well as the voice encoding functions.SONET has the capability to reduce the buffering amount and the data transfer timing. Themultiplexing protocol, SONET has the capability to conduct complex multiplexing; it hasalso the capability to carry a large amount of data via optical fibre over the large distance.SONET can be connected in following ways- point-point, linear, unidirectional path-switched ring, two-fibre bidirectional line-switched ring and the for-fibre bidirectional line-switched networking (Doherty, Anderson and Della 2008).SONET has a heavy multiplexed structure, with the header interspersed between thedata in the more complicated way. This allows the encapsulated data to have their own frameto ‘float around’ related to the SONET frame rate. SONET allows excess padding for the datawhich is multiplexed to progress within the overall framing; here the data is clocked at avaried rate compared to the frame rate (SONET/SDH 2017). The protocol made can be morecomplicated by the allowance of this padding; however, enhanced all-around performancecan be gained at the end. SONET standard was deployed in North America and is termed as the NorthAmerican Standards. Synchronous Transport Signal (STS) is not only carried out through thefibre optic line, but also the signal is carried out electronically through the coaxial cable line.From the hierarchy of the SONET, it can be noted that the STS-1 operates at the OC-1 levelat 51.84 Mbps and it has the capacity of 28 DS1s. It can be also noted that STS-3 operates atthe OC-3 level at 155.52 Mbps and it has the capacity of 84 DS1s (5 Wan Technologies
