GSMA IR34 IMPLEMENTATION IN AMS-IX Inter-IPX

Thomas O’Sullivan

AMS-IX

i3 Workshop

Istanbul September 9th 2013

AMS-IX is

An internet exchange

A GRX exchange

An IP eXchange.

GRX exchange

‣Since 2002 AMS-IX offers its GRX platform (CUG) to

carriers that interconnect MNO’S for data roaming

purposes:

‣ Technical: GRX VLAN, GSMA supplied Root DNS and dedicated equipment and connection

‣ Administrative (‘accreditation’): Memorandum of

Understanding (MOU)

‣ AMS-IX the main GRX peering point globally,

interconnecting 25 GRX providers.

GRX members:

• Aicent• Astelnet• Belgacom ICS• CITIC Telecom• Comfone AG• Deutsche Telekom• Emirates Telecommunications• France Telecom• iBasis• MTT• MTX Communications• NTT Communications• OTEGlobe

• Portugal Telecom• SAP (form. Sybase 365)• Syniverse• Tata Communications• TDC Solutions• Tele 2• Telecom Italia Sparkle• Telefonica IWS• Telekom Austria• Telenor Global Services• TeliaSonera ICS• Telstra

These 25 connect over 700 MNO’s for GRX

• Most ports are typically FE (100 Mbit/s).• Private IP network (separate from internet)• No QoS associated.• No inclusive SLA.• Best Effort basis.

GRX TrafficPeaks summer and New Years’ eve

GRX Traffic growth is 100% year on year

GRX traffic 0.1% of total AMS-IX traffic

‘Broadening the scope’

An IP eXchange

Idea in 2010: AMS-IX as a catalyst for IPX?

• Ability to provide platform performance KPI’s in accordance with IR34.

• Excellent historic ‘best effort’ track record.

• Neutral.

• Capable of handling expected traffic growth.

AMS-IX IP eXchange-Physical setup

• Minimum 2 x 1GE redundant Connections in separate co-locations.• Can be scaled to multiple 1 GE or 10GE Lags or even 100GE ports.• 10GE / 100GE ports are connected to 2 Edge switches via a photonic switch which

adds further resilience.

• Private IP network, separate ports, no ISP tagging.• IPX Service include Service Communities.• For GRX, requirement still for MOU.• No marking done by AMS-IX, eg priority.• IPV4 and IPV6 supported.• Inclusive SLA based on IR34 recommendations.

AMS-IX IP eXchange logical setup

IR34: Service Communities

• Service Communities isolated from each other using separate VLANs.• Service Communities you connected to is a matter of choice.

Traffic Classes in IR34

• 4 defined: - Conversational, streaming, Interactive,

background• AMS-IX only focuses on the KPI’s that

apply to the highest class : (‘conversational’ /EF )

- Provides highest KPI’s

- In line with AMS-IX policy of non intrusive

IR.34 QoS Parameters

• Service Availability • Packet loss • Delay• Jitter

• Every switch in I-IPX network has a measurement probe attached• The probes use IEEE 802.1ag Connection Fault Management with ITU-TY.1731

Delay Measurements (OAM for short)• Probe measurement done on a separate VLAN.• Frames sent out 10 times second for delay and jitter.• Frames sent once per second for frame loss.

AMS-IX IP eXchange-IR34 Measurement

Availability:

The proportion of time that the AMS-IX switching platform is considered available to the member on a monthly basis:

GSMA IR.34 : 99.995% per month

AMS-IX SLA : 99.995% per month.

Roundtrip Delay (RDA) :

Intra-continental traffic inside North-Europe = maximum RTD of 40 mille-seconds.(EF)

AMS-IX SLA : <0.5 mille-seconds 1 way

(< 1 mille-second 2 way)

Jitter :

• Intra-continent Jitter Value - 5mS per GRX/IPX Provider (maximum of 2 involved in the service delivery chain)

• Inter-continent Jitter Value - 10mS per GRX/IPX Provider (maximum of 2 involved in the service delivery chain)

• AMS-IX : < 0.1 milleseconds

Packet Loss:

The ratio of dropped packets sent from from source to destination in percentages on a monthly basis:

< 0.1% Highest service ( EF +AF4)

AMS-SLA : <0.05 %

I-IPX SLA Reporting

• Inter-IPX connections have inclusive SLA.• Provide Monthly Service Reports.

- performance and availability• Continuously monitor the platform.• Real time performance graphs on website.• High Service Credits given:

e.g. 100% for > 22 minutes downtime• Service Credits also given for packet loss, delay

and jitter.

AMS-IX Inter-IPX ServiceCurrent Happenings

• Currently service very reliable, no service credits given.• Inter-IPX offered in Hong Kong and Caribbean AMS-IX

exchanges.• Currently 12 Providers have signed up to I-IPX

platform.• Others expected to follow soon.• LTE seems to be the main driver for current

momentum.

I-IPX Contracts signed:

• Aicent• Belgacom ICS• Comfone AG• Deutsche Telekom• Emirates

Telecommunications• iBasis• MTT

• Syniverse• Tata Communications• Telefonica IWS• Telenor Global Services• Telstra• Vodafone/SAP

List to be more easily available on AMS-IX website

AMS-IX is not providing End to End Solution for I-IPX but as an IP eXchange

• Seamless and transparent connection.• IR34 based accountable SLA’s.• Multiple peering partners in private

network.• Scalable network.• Neutral party.
