MPLS dual-label stacking packets are _____ bytes longer than original IP packets.
MPLS dual-label stacking packets are _____ bytes longer than original IP packets.
MPLS (Multiprotocol Label Switching) headers are each 4 bytes in size. When using dual-label stacking, there are two MPLS headers. Therefore, the packet size increases by 4 bytes for each label, resulting in a total additional size of 8 bytes when two labels are used.
Each MPLS Header (Label) has 4 Bytes of lenght. Usually MPLS only allocates one label for packet. But some advanced aplication of MPLS use multiple labels. For each one label additional, it increases the original packet 4 bytes. One label --> No increment two labels --> + 4 Bytes Three labels --> +8 Bytes
