Oversubscription StateESP TypeASR 1000 Chassis Type
No ESP oversubscription.
ESPs interconnect device handles
the entire 10G incoming traffic.
ESP-2.5 G and ESP-5 G
(Supported only on ASR-1002)
•
ASR1000-SIP10G
•
Incoming rate from SPAs.
Maximum 4 multiplied by
11.2 Gbps
•
Outgoing rate towards ESP
11.2 Gbps
Conclusion: SIP10G is always
oversubscribed.
ESP is oversubscribed.
Example:
Input rate from (example) 3 carrier
cards is 3 multiplied by 11.2Gbps
Output rate towards
QFP=12.8Gbps
ESP-10G
ESP is oversubscribed.
Example:
Input rate from (example) 3 carrier
cards is 3 multiplied by 11.2Gbps
Output rate towards QFP=25.6
Gbps
ESP-20G
No ESP oversubscription.
Example:
Input rate from (example) 3 carrier
cards is 3 multiplied by 11.2Gbps
Output rate towards QFP=2*25.6
Gbps
ESP-40G
No ESP oversubscription.
Example:
Input rate from (example) 3 carrier
cards is 3 multiplied by 11.2Gbps
Output rate towards Yoda=4*25.6
Gbps
ESP-100G
