Abstract

Abstract:

Cloud datacenter demand on new techniques and new architecture were summarized firstly. And also the mainstreams of VxLAN technical schemes were analyzed. Then typical VxLAN applications in cloud datacenter network were studied. Finally, several VxLAN problems were discussed in case of scale applications in cloud datacenter.

Key words: cloud datacenter, overlay network, spine-leaf, Spine, software defined networking, VxLAN
