### Présentations
|
|
|
|
- Épita 2018, a une époque
|
|
- Sys/Net admin alternant chez FranceIX
|
|
- Fait ses slides deux jours avant la conf
|
|
- Système à la base, réseau par assimilation
|
|
|
|
### Un IXP c'est koa
|
|
|
|
- Internet Exchange Point
|
|
- Interconnexion de réseaux et services associés
|
|
- En gros, un (gros) switch
|
|
- Gné ??
|
|
|
|
### Le Nain Ternet
|
|
|
|
- Des paquets dans des fils
|
|
- Interconnexion de réseaux (AS)
|
|
- Deux méthodes : transit et peering
|
|
|
|
### Situation initiale
|
|
|
|
\centering{
|
|
\begin{tikzpicture}[sibling distance = 5em, every node/.style
|
|
= {shape=ellipse,
|
|
draw, align=center, top color=white, bottom color = red!80}]
|
|
\node[minimum height=3em] (t) {Réseau T};
|
|
\node[below left=of t] (a) {Réseau A};
|
|
\node[below right=of t] (b) {Réseau B};
|
|
\draw[link] (a.north) -- (t.south west);
|
|
\draw[link] (t.south east) -- (b.north);
|
|
\end{tikzpicture}
|
|
}
|
|
|

### Mangez des fruits
|
|
|
|
\centering{
|
|
\begin{tikzpicture}[sibling distance = 5em, every node/.style
|
|
= {shape=ellipse,
|
|
draw, align=center, top color=white, bottom color = red!80}]
|
|
\node[minimum height=3em] (t) {Réseau T};
|
|
\node[below left=of t] (a) {Réseau A};
|
|
\node[below right=of t] (b) {Réseau B};
|
|
\draw[darrow] (a.north) -- (t.south west);
|
|
\draw[arrow] (a.150) -- (t.195) node[shape=rectangle,draw=none,fill=none,bottom
|
|
color=white,midway,above=.1cm] {\$};
|
|
\draw[darrow] (t.south east) -- (b.north);
|
|
\draw[arrow] (t.345) -- (b.30) node[shape=rectangle,draw=none,fill=none,bottom
|
|
color=white,midway,above right=.1cm] {accords \\ préalables};
|
|
\end{tikzpicture}
|
|
}
|
|
|
|
### De peer en peer
|
|
|
|
\centering{
|
|
\begin{tikzpicture}[sibling distance = 5em, every node/.style
|
|
= {shape=ellipse,
|
|
draw, align=center, top color=white, bottom color = red!80}]
|
|
\node[minimum height=3em] (t) {Réseau T};
|
|
\node[below left=of t] (a) {Réseau A};
|
|
\node[below right=of t] (b) {Réseau B};
|
|
\draw[darrow] (a.east) -- (b.west)
|
|
node[shape=rectangle,draw=none,fill=none,bottom color=white,midway,above=.1cm]
|
|
{accord de peering};
|
|
\end{tikzpicture}
|
|
}
|
|
|
|
### Les gestes qui sauvent
|
|
|
|
- MPLS/VPLS everywhere
|
|
- Encapsulation de l'Ethernet pour le transport
|
|
- Des grosses machines qui empilent des paquets
|
|
- D'autres protocoles sont possibles (EVPN/VXLAN, entre autres)
|
|
|
|
### Des étiquettes partout
|
|
|
|
- Multiprotocol Label-Switching
|
|
- Transport par commutation de labels
|
|
- Supporte la couche 2, 3, de la voix, ....
|
|
- Établit des chemins de bout en bout
|
|
|
|
### Je VPLS tomber, je trouve pas de jeu de mot
|
|
|
|
- Virtual Private LAN Service
|
|
- Service de L2VPN multipoint-to-multipoint
|
|
- Permet d'abstraire[^1] le réseau en un gros switch
|
|
|
|
[^1]: oui, ça se dit

### Feux de signalisation
|
|
|
|
- L'IXP fournit d'autres services
|
|
- Route Servers
|
|
- Supervision et maintenance de l'infra
|
|
- Mise en place de peering privés
|
|
- Protections diverses (DDoS, BGP Hijacking, etc\dots)
|
|
- \dots
