The Internet has become a success because the excellent network architecture suorts the oenness and innovation of network alications. The driving force for transforming the network architecture is the ever-changing requirement. The Internet lus era has ut forward new requirements for the network core layer. is laying an imortant role in the new round network architecture transformation, and inherits Internet's oenness and innovation at the network core layer. The success of Internet alications is created by C rogrammers. The success of the network core layer in the Internet lus era will be created by network rogrammers! 29 5
