E2E circuitsDebriefing...

Building e2e circuits
• This is complex• Synchronization required• Service offered has strong impact on network
architecture• Monitoring not straightforward
• What for ?• Provide more bandwidth ?• Provide 100% private circuit ?
11
About setup
• Several months needed• Hours of conf calls• Agreement required all over the path
• VLAN IDs ...• Private addresses usage
• Will we do better next time ?

12
Provide more bandwidth ?
• True for 10GE circuits• What about 1GE ?
• We can set up 1 Gbps IP traffic much moreeasily
13
Provide 100% privatecircuit ?
• We have Ethernet switches on thesecircuits• Equipment handles other traffic too• No prioritization used (in Renater so far)
• Some use EoMPLS• Some others have IP over MPLS
• And this differs in all parts of the circuit

What about monitoring...and day to day operation
• Very complex!• Difficult to find where the problem comes
from• We had to configure private addresses on
equipment on the path!• Good this was multipoint circuit • Privacy issue ?
• perfSONAR + E2ECU
+ ...
15
And about resiliency ?
• Almost no resiliency available• And outages are often very long to
manage• Up to 3 days !

16
And what for ?
• Customers do IP at the edge and have aBGP peering !
17
Requirements toestablish E2E circuits
• Define end to end locations• Circuit type to be validated and decided by the NREN
• VLAN &/or EoMPLS• PIP E2E• Lambda E2E• L3 VPN
• Define services and apps which flow through the circuit• IPv4, IPv6, Unicast, Multicast …• MTU requirements
• Specify IP address plans (private or not)• Define BW and SLA requirements for the E2E circuit
• Jitter, OWD, BW, …
• Who pays what ?
