• Tunnel mode IPsec being mandatory and transport mode being optional
• Likely that transport mode used to protect X2 *reduced overhead and low traffic)
• SeGW used to offload EPC and allow IPSec scaling
• Protection optional on S1-MME and S1-U

LTE/SAE Architectural RequirementsLTE/SAE factors Network Requirement
Direct “X2” interface & handover between eNodeBs Distributed network intelligence
Offload architecture, increased Bandwidth, traffic offload, Video Insertion/Caching Increased RAN intelligence
IPSec requirement in the backhaul IPSec gateways (IKEv2) requirement in the Aggregation
Authentication and Security framework Intuitive and secure networking
IPv6 framework fully defined IPv6 and IPv4 support mandated
Multicast requirements Multicast and Multicast VPN support
Synchronisation (Freq. & Phase) requirements Packet and Physical Layer options
Strict Latency requirement (LTE/SAE standard) Optimal platform and network design required
Intelligent H-QoS requirements Extensive UNI QoS capabilities required
Wholesale/RAN sharing offering with Multi-Operator Core Network/Gateway Core Network Intelligent network identification and forwarding
Simplified Fast Convergence options Optimised and simplified IP/MPLS fast convergence
OAM mechanisms & Performance monitoring Troubleshooting and fault isolation/SLA metrics

IP/MPLS MPLS-TP(T-MPLS)
Comment
L2 Services EVC, VPLS, ATM, TDM
EVC, ATM, TDM VPLS is common in wireline business services offerings.
L3 Services L3VPN No For wireline business services and broadcast separation domain
Any-to-Any Traffic Matrix
Yes No Needed for optimal X2 interface handling
Multicast Yes No Required for E-MBMS services
IP Core Interoperability
Native No, needs PE router for L2 to L3 connection
For eNB to S-GW connection, IP (L3) connectivity is needed
Service distribution L3VPN, GGSNSAE/PDN
No Services closer to the subscriber for local breakout, business services and CDN
Synchronization SyncE,IEEE1588 (OC, BC)
SyncE, IEEE1588 at L2 only
L2 technologies transport IEEE1588 transparently, can not improve stability midway.
Security SeGW (IPSec) No For S1 interface encryption on untrusted aggregation (microwave, wholesale etc.)
Maturity Mature Early standard/no standard for T-MPLS
Non-mature standards may cause problems with interoperability and OAM.

No IGP route is propagated from Aggregation to the Core. IGP area has routes for that area only plus routes to core ABRs Only the core ABR’s are propagated from L2 to L1 LDP labels are used to traverse each domain and reach core ABRs BGP labels are used by Labeled BGP PEs & ABRs to reach Labeled BGP PEs in remote areas Service (e.g. PW) labels are used by Label BGP PEs Note: Remote LFA could add a 4th Label if used
