Dear Muhammad Awais,

in particular, NFV can be used in Software Defined IXPs (SD-IXPs) to improve various QoS Parameters and Security - for example:

• Load distribution in large IXPs
• Reporting on Congestion
• Blackholing Services against (D) DoS attacks
• Intrusion Detection / Blocking at IXP Border

See the following sources of literature:

• Marco Chiesa, et al.: „Inter-domain Networking Innovation on Steroids: Empowering IXPs with SDN Capabilities“; Pre-print Version

Dear Awais,

NFV combined with the IXP can surely provide the better QoS. For example, a problem with the IXPs is location discovery using broadcast traffic. The broadcast traffic increases with increase in the size of the network that caused a broadcast storm. Broadcast storm results in high latency, low throughput, underutilization of network and sometimes it can cause the entire IXP operation to stop. To address, these problems, SDN based IXPs are developed such as:

and

• Gianni Antichi, .. , ENDEAVOUR: A Scalable SDN Architecture For Real-World IXPs

These schemes have improved the manageability and scalability of the IXPs. In addition to that these schemes
