Task $5$

The following figures $5\mathrm{.}1$ and $5\mathrm{.}2$ show two corresponding consecutive RTP payload packets. Be

aware that from the usual $26$ Byte Ethernet II overhead only $14$ Byte are captured by the protocol

analyser, therefore please consider additional $12$ Byte Ethernet overhead.

Frane $69$: $94$ bytes on wire $(752$ bits$),94$ bytes captured $(752$ bits$)$ on interface $\backslash$Device WPF$\_(64$:
