33 Akamai’s IP Relay TURN Service

34 ©2013 AKAMAI | Proprietary & Confidential - FASTER FORWARD TM Peer-to-Peer is Predicted to Explode APPLICATIONS Real-time Communications CHATTING GAMING CONFERENCING SALES & SUPPORT HTML5 & WebRTC has standardized peer-to-peer communications WebRTC enabled devices is growing A TURN solution will be required to transverse firewalls between these WebRTC connections Source: Google, Disruptive Analysis, & ABI Research

35 ©2013 AKAMAI | Proprietary & Confidential - FASTER FORWARD TM TURN Inefficiencies Problem: Peer-to-peer connections are complicated by NAT devices (address- and address-port mapping). If both peers behind a NAT, they may not be able to talk directly. Problem: TURN service can significantly impact performance when either of the end-points are far away from the centralized TURN server. Problem: Geographically dispersed clients can have performance issues even when connecting directly due to long latency and packet loss. Solution: Akamai's IP Relay service provides an improved, fully distributed TURN-like service Global deployment, fault-tolerant technology Akamai's famed network knowledge SureRoute™ technology to find better routes than the Internet Improve Performance: UDP encoding over the long "middle mile” Client A Firewall A Client B Firewall B TURN Server

37 ©2013 AKAMAI | Proprietary & Confidential - FASTER FORWARD TM How does the IP Relay service work? Customer Directory Service Client A Firewall A EDGE B Client B Firewall B Clients : Each Client is engaging in peer-to-peer communication. The clients will typically have a private IP address that is not publicly routable. Akamai serves as a globally distributed TURN service Directory service: A customer owned and operated directory service that functions as a backend communication path for exchange of information required for connection establishment. Clients Connect To Akamai Edge: Akamai determines the ideal Edge server for each client, providing the best connection into the Akamai Network Akamai Optimizes traffic between Edges: The IPA network optimizes the connection by reducing latency and improving throughput, providing both clients a better experience EDGE A

42 Packet Loss

43 ©2013 AKAMAI | Proprietary & Confidential - FASTER FORWARD TM Why Packet Loss Matters 5% Packet Loss Effects of Packet Loss on H.264 video codec 0% Packet Loss Effects of Packet Loss Video: “Blocky” video and a frozen or jerky end user experience. Audio: Stutter or intermittent speech. Experience: Lower resolution video Add skype video stats

44 ©2013 AKAMAI | Proprietary & Confidential - FASTER FORWARD TM Akamai IP Relay Reduces Packet Loss on Long Haul Calls Packet loss on “long haul” calls reduced to sub-1% Packet Loss metrics shown are end to end, including last mile call segments beyond the IP relay. Many test calls are nearly devoid of packet loss. Packet Loss (%) Internet Loss Akamaized Key Best Unacceptable - ->

45 Latency

46 ©2013 AKAMAI | Proprietary & Confidential - FASTER FORWARD TM Akamai Improves Latency on Long Haul Calls by up to 35% Key Increased latency resulting in callers frequently talking over one another reduced effectiveness compared to audio calls 150 ms 300 ms Gold Standard AcceptableUnacceptable For intrinsically high latency connections, unless packet loss is tightly constrained, it becomes practically impossible to maintain a high quality video call.

47 ©2013 AKAMAI | Proprietary & Confidential - FASTER FORWARD TM Akamai Improves Latency on Long Haul Calls by up to 35% Many long haul video calls experience unacceptable latency over Public Internet Latency metrics shown are end to end, including last mile call segments beyond the IP relay. Akamai brings many of these video calls into the “acceptable” quality range Latency (ms) Internet Latency Akamaized Key <--- AcceptableUnacceptable ---> Increased latency resulting in callers frequently talking over one another reduced effectiveness compared to audio calls
