Virtualized L2 networks over L3 transport

Muhammad Durrani, Brocade Communications Inc

Cloud computing and virtual machines require significantly more logical networks than traditional data center networks, and past network segmentation techniques such as VLANs cannot scale adequately. Several technologies were developed to enable Layer 2 overlay networks that are tunneled over Layer 3 for scalable cloud network architectures. This presentation will briefly highlight existing challenges, and then introduce Technologies enabling Virtualized L2 overlay networks, brief concept and related deployment case studies

TRILL Benefits in Service Provider Data Centers and IXP

Francois Tallet, Cisco

Layer 2 technologies are desirable in Service Provider Data Center and IXP environment. After reviewing the typical limitations of those technologies, this presentation will describe how they are addressed by the IETF Transparent Interconnection of Lots of Links (TRILL) standard. A few common designs based on TRILL will also be introduced.
