- Complexity, complexity, complexity (unbounded, nobody knows what new combinations of layers may be needed in the future
Layers are resource allocators, provide IPC services over a certain scope, they all have the same functions
Core/backbone: IP/MPLS
Metro aggregation: Carrier Ethernet
Access: xDSL, FTTH (PON tech), WiFI, LTE
Services: L2/L3 VPNs, Internet access, IMS
Micro DC: C-RAN, Mobile Edge computing
Metro/regional/national DCs: provider service platforms (DNS, SMTP, etc…) LTE EPC (S-GW and/or P-GW, MME), IMS, cloud hosting, NOC, etc
SYN-Ack Attack: must guess which of 2^16 CEP-id.
Data Transfer: must guess CEP-id and seq num within window!
Reassembly attack: Reassembly only done once.
No well-known ports to scan.
