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 ?

6

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

14

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 !

8

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 ?
