Keeps surprising me, to many DevOps is still a novelty. | |
Not to reinvent the wheel: https://dl.dropboxusercontent.com/u/778575/IMG_0964.jpg | |
http://www.pmacct.net # NetFlow collector and BGP agent. | |
http://sdn-internet-router-sir.readthedocs.org/en/latest/ # UI and API to pmacct | |
Puppet seems to be the choice for network vendors: Juniper, Arista and, lately, Cisco. | |
Ansible is a preferred tool for startups though. | |
http://www.ntop.org/products/netflow/nprobe/ # Outperforms many specialized pizza boxes | |
https://github.com/6connect/irrpt # IRR? Anyone uses it? Would JF be interested? | |
https://github.com/inex/IXP-Manager # Hey, http://yycix.ca. | |
https://github.com/spotify/napalm # Thanks, Spotify and Netflix! Complements Ansible nicely | |
https://github.com/Exa-Networks/exabgp # Another python toolkit (Thanks Samir!) | |
BGP Based SDN: | |
- Agents: Quagga, Bird, ExaBGP (or its fork Bagpipe BGP) or ODL (ONOS?) | |
- Eventual consistency for free | |
- BGP-LS | |
- FlowSpec (RFC5575) | |
- L3VPN (RFC 4364) | |
- EVPN (RFC 7432), , BGP Enc Community (RFC 5512) | |
- Remote Triggered Black Hole, there's an official IPv6 blackhole RFC 6666 | |
- BGP in Datacentre @ Microsoft: draft-lapukhov-bgp-sdn-00 | |
http://tsung.erlang-projects.org # Effective load testing | |
Procedures: Simplify -> Standardize -> Automate -> Abstract | |
RANCID -> git -> Gerrit -> Ansible (-> API) | |
http://xkcd.com/1205/ | |
NETCONF and YANG: | |
Atomic, Consistent, Independent, Abstract API over XML. Not stateless! | |
Works best on JunOS. | |
YANG is a human readable data description language. Also, worst case of design by commitee. http://www.openconfig.net | |
NFV: | |
Use cases: | |
Virtual Appliances (i.e. BGP RR, FW, LB, IDS) | |
Enterprise Remote Site | |
4over6: IPv6 for access, VM-based psudowire termination vor IPv4 (Accessible via IPv6 anycast) <= Deutsche Telecom (Snabb sw on VMs) | |
vCE (per-customer services) | |
vPE: CPE <=> P | |
E sw <=> vPE | |
Heavy reliance on SR-IOV, DPDK, PF_RING, etc. | |
MPLS, IP tunnels, EVPN to pull the client's data into cloud. Also, source/segment routing. Also, Juniper Contrail. | |
https://github.com/Juniper/OpenClos # Neat ZTP script for Junipers | |
SDN Use Cases: | |
Arista XMPP(!) & ZTP, `show event-monitor sqlite .schema` | |
Traffic Engineering (PCEP RFC 5440) | |
Programmable Network Taps | |
Arista syslog server to let permitted flows through | |

SDDC | |
"All infra is virtualised and delivered as service. Entirely delivered as software" | |
Amusing how distributed FS is said to be "for hipsters". People have barely moved from iSCSI to NFS. | |

Hyper-V Extensible Switch is plain amazing. |
