Question:
The figure below presents a network applying the multi-protocol label switching (MPLS) principle.
The network consists of routers and links. We distinguish two types of routers: Label edge routers (LER) and label switching routers (LSR).
The LSR performs one of the following label operations:
Swapping: replace current label by a new label.
Pushing: move label onto label stack.
Popping: remove label from label stack.

- Explain briefly the use of the TTL field in the shim header. Which other protocol includes a TTL field?
- How many service classes can MPLS support?
- How many different labels does MPLS support, knowing that labels ranging from 0 to 15 are reserved for special purposes?
