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 Traffic Peaks 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 : % per month AMS-IX SLA : % 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 Service Current 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. Summary
