We examine the simultaneous time-series spectral data for NI 1319 deg and CII 1335 deg and CII and OVI obtained from the SUMER instrument on the SOHO spacecraft. The observed 4-5 min network oscillations can be interpreted in terms of kink and sausage waves propagating upwards along thin magnetic flux tubes. Transverse kink waves can be generated by random foot-point motions driven by exploding granules at the photospheric level. As they propagate within flux tubes, their amplitude grows exponentially with height and become non-linear, thereby undergoing a mode transformation becomes longitudinal sausage type. We propose that for the network bright regions these sausage waves are responsible for the 3.5 mHz power peak. Numerical results based on thin flux tube equations will be compared with observations. Our two layer isothermal atmospheric model predicts a coupled oscillator frquency which matches fairly well with the network observations.
