Peering Lessons – 5 year Service Provider Journey
Liquid Telecom operates the largest fiber network in Africa, spanning 18,000 km. They actively peer with internet exchange points (IXPs) across Africa and Europe to lower latency and increase throughput. Peering has grown Liquid Telecom's intra-African traffic significantly faster than traffic between Africa and Europe. As more peers connect directly through IXPs, Liquid Telecom now routes over half of its inbound traffic via peering arrangements rather than transit agreements, reducing costs and improving performance for users. Continued expansion of IXPs and adherence to intellectual property laws can further drive traffic shifts from transit to peering.

Editor's Notes
- #3 Liquid Telecom is the leading independent data, voice and IP provider in eastern, central and southern Africa. It supplies fibre optic, satellite and international carrier services to Africa’s largest mobile network operators, ISPs and businesses of all sizes. It also provides payment solutions to financial institutions and retailers, as well as award winning data storage and communication solutions to businesses across Africa and beyond. Put simply, we connect people.

- #10 Routing issues. Some peers advertise more specific prefixes at some Ixs. Some we end up exchanging traffic in URPF: unicast reverse path forwarding Unicast Reverse Path Forwarding (URPF) helps to mitigate problems that are caused by malformed or forged IP source addresses that are passing through a router. Loose URPF checks the packet and forwards it if there is a route entry for the source IP of the incoming packet in the router FIB. Capacity management – when you peer at different IXs, make sure you have enough capacity for traffic – EG, if you have a Peerig in SA, and non in East Africa – then the KE – SA link has to be up to scratch. Also enough capacity at the IX CDN routing – t Not possible to have CDN in each country – they are regional. Cross boarder links have to be big enough to carry content network.

- #20 Telkom traffic More traffic from Telkom into Liquid Telecom They need us more than we need them Usually big ISPs only want to peer if there is enough volume. They are quick to want to sell ‘local transit’ One method is to ask for temporary peering for say 3- 6 months make sure you record interface and flow traffic if peering via IXP.
- #21 “Netflix doesn’t offer services in Kenya, but it doesn’t mean that Kenyans cannot access services. Some people are using Virtual Private Network (VPN) services to access content on Netflix, this shows there is demand for video services, which will drive up the demand for higher capacity,” Roberts identified piracy and lack of enforcement of Intellectual Property laws as a major hindrance for companies interested in investing in streaming services; whether local or international “If you can get the latest Hollywood movies at a cost of a dollar in downtown Nairobi, it becomes hard to convince one to pay five dollars to stream the same movie, this points to a weak IP law enforcement, which can kill business,” said Roberts
