TPIX

How to connect two IXes?

Konrad Plich, Robert Woźny

Warsaw, 17th of March, 2011r.

Internet Exchange Point at a glance

• Why to peer? save money, local trafﬁc stays local, better performance...

• Private peerings: does not scale; solution: Internet Exchange Point

• Simple concept: any place where ISP come together to exchange trafﬁc

• Layer2 (Ethernet) or Layer3 (router based) exchange

• Layer2: ISPs free to set up peering agreements with each other as they wish

• Layer3: marketing of the transit ISPs instead of IXP

• Each ISP participating in the IXP connect a router...

• router needs to be able to run BGP! (using public ASN, NOT private one)

• Route Servers: help to scale routing

• provided as service, usage is NOT mandatory

• only two eBGP sessions rather than N

• simpliﬁed routing conﬁguration management on ISPs routers

• Community Based Policies: Bi-Lateral Peering, Multi-Lateral Peering, Mandatory

Multi-Lateral Peering

TPIX: integration of services on the Ethernet platform

In the collocation facility Nowogrodzka, Piękna and the LIM building

we installed platform based on Ethernet switches...

• cheap access ports - 1GEth and 10GEth (10GEth available only on the core

switches)

• possibility to exchange Internet trafﬁc (OpenPeering service)

• possibility to create IP Interconnection with TPNET network

• private VLANs between users of the platform (without bandwidth restrictions)

• possibility to use TP’s Metro Ethernet platform to provide services in Poland

TPIX: integration of services on the Ethernet Platform

TPIX Platform Services are available not at three locations in Warsaw...

We can use TP’s Metro Ethernet to provide the reasonably priced access to TPIX

services. In the more than 200 locations (collocation facilities - Telehousing PRO) we

can provide a set of functionality available on the TPIX’s Platform including:

• 1GEth access port (with the same price as in Warsaw)

• Paid peering with TPNET network

• Private VLANs to the TPIX Platform members’ ports (paid per bandwidth)

• Transit to TPIX’s OpenPeering (paid per bandwidth)

TPIX’s services are also available in the customer’s location using retail MetroEthernet

service. In this case, the increased price of the port and of the bandwidth covers the

increased TP costs.
