E-VPN and PBB-EVPN Take Data Center Interconnect to the Next Level

Tina-lamBy Tina Lam, Product Manager

MPLS based Layer 2 VPN has been around for over 10 years since the inception of IETF Pseuduowire Edge to Edge (PWE3) Working Group. Many drafts and standards have been added, since then, to address different applications and to improve scale and convergence in different topologies. L2VPN as a whole is widely deployed in both service providers and enterprises, from Ethernet services, to fixed and mobile convergence, to enterprise campus layer-2 transport.

Recently, one emerging driver that has been picking up a lot of momentum is to use L2VPN for Data Center Interconnect (DCI). Data centers are often situated in different locations, to be geo-redundant for the purpose of workload mobility and business continuity. At the same time the physical location of the data center has to be transparent to users and to applications. Hence the need for layer-2 connectivity between sites. While Ethernet over MPLS (EoMPLS) and Virtual Private LAN Service (VPLS) have been used for this purpose, DCI presents new requirements and challenges not fully addressed today.  To keep the data center always on, and to utilize all the resources and links as efficiently as possible, data centers need all-active redundancy and load balancing. The technology should be as simple as possible to provision and manage Read More »

The DCI Blog is Here!

Hi,

Part of Cisco’s Data Center strategy includes Data Center Interconnect (DCI).  DCI is a solutions-based approach to virtualize an organization’s 2 or more Data Centers.  That is, multiple Data Centers can be architected so that they can seamlessly share resources while also delivering new services addressing today’s business challenges and opportunities.

I’m a Product Manager in our Systems Architecture and Strategy Unit (SASU) where we develop DCI enabled architectures *and* put them through our solutions test bed.  Our output includes White Papers, Industry Presentations as well as Design and Implementation Guides with the Cisco Validated Design (CVD) designation.

My ultimate goal here is to share what’s happening and help point you in the right direction as you make your DCI decision or just want to learn about the solution in general. To get you started, please check out our DesignZone as well as more specific DCI content here.
