Abstract

Local peering of traffic has substantial benefits for operators and end-users, alike.

In this work, we aim to provide a software defined (SDN) internet exchange point (SDX) architecture with a framework to offer differentiated services at IXP customized specifically for the needs of Pakistan internet community in particular and any peering IXPs in general.

SDN provides promise in terms of lower infrastructure costs and abstraction of network functionality in separate control and data planes. Efforts like project CARDIGAN (REANNZ/Victoria University) seek to separate control and data planes for internet exchange points.

Noise Lab at Princeton University, USA have provided an architecture for industrial SDX. To quote, “deploying software defined networking (SDN) at Internet exchange points (IXPs) offers new hope for solving long standing problems in inter-domain routing. At the SDX, ISPs can apply many diverse actions on packets based on multiple header fields, and distant networks can exercise “remote control” over packet handling. This flexibility enables applications such as inbound traffic engineering, redirection of traffic to middle-boxes, wide-area server load balancing, and blocking of unwanted traffic. Supporting these applications requires effective ways to combine the policies of multiple ISPs.”

Over and above, only a single IXP exists in a country like Pakistan. An integrated IXP architecture complying to SDN paradigm of separate control planes and data planes with a brokerage for differentiated services holds tremendous promise and potential for internet community in Pakistan. In this work, we are designing and implementing a software defined internet exchange point in Pakistan in collaboration with international partners at Tokyo University, Faucet Foundation and Victoria University New Zealand.
