Increased bandwidth requirement with SRTP
The table provides an overview of the increase in bandwidth requirements caused by the
SRTP. The bandwidth is assumed to rise by 70 bytes as a result of RTP, UDP, IP, 802.1Q
VLAN tagging and MAC (incl. preamble, FCS). SRTP accounts for an additional increase of 10
bytes. This brings the overall increase to 80 bytes.
