Problem:
Non-transient link
degradation (e.g., due to rain
fading):
• 500 Mbps -> 100 Mbps
• Send TE notification
Mitigation:
• Redirect 400 Mbps
PCEP
Openflow
I2RS
Mitigation steps:
• Analyze current load and
impact on SLAs
• Build & calculate impact of
new traffic paths
• Send instructions to
forwards traffic on new paths

LTE - Transport aware radio
3G/LTE
3G/LTE
Problem:
• X2 makes sense for handover,
but transport network is
congested
• X2 would actually degrade
performance, creating more
congestion and wasting radio
resources
Mitigation:
• eNB checks with TNC for any
possible path
• PM measurements to
check latency
• BW constraints checked
• Resolution given to
network
• If no resolution found,
eNB does not use X2
