9 BIC Motivation Focus is on High Speed Networks, bandwidths upto 10 Gbps. Transport Protocols should be able to transfer a large amount of data over a long distance within a short amount of time. With existing TCP Congestion Control protocols, utilization of link is not optimal for high speed networks. TCP Fairness the ability to share bandwidth with TCP Connections on low-speed networks.

10 Window Growth Function - BIC

11 HTTP/2 Binary Protocol Opens single TCP Connection per domain Multiple requests are streamed into one connection Streams are Multiplexed Prioritized flow controlled HTTP/2 Application Binary Framing TLS Transport Network Physical Header Compression Change in wire format, no change in semantics
