In the quest to build a data center network that is flat, fast and fault tolerant, the networking industry has served up a new two-tier architecture made up of Top-of-Rack or ToR server connecting switches and highly dense Core switches. Core switches connect ToR devices. The key question is how best to provide switch connectivity to deliver a lossless, high performance, low latency fabric that supports virtualization mobility. The answer is found in Multi-Chassis Link Aggregation Group or MC-LAG, Transparent Interconnection of Lots of Links or TRILL and/or Shortest Path Bridging (SPB). Dhritiman Dasgupta, Director of Product Marketing for Fabric and Switching Technologies at Juniper Networks, discusses its QFabric approach and why TRILL’s hair pinning method to inter-VLAN routing is a poor approach. It’s a fascinating discussion that you have to listen to. You can also download a white paper on this topic here.

Juniper Networks has a long history of supporting industry standards that are mature and enable customers to effectively solve their networking problems. Therefore, before jumping on the Transparent Interconnection of Lots of Links (TRILL) bandwagon, Juniper took a close look at how the protocol proposes to solve the fundamental issues plaguing the data center, specifically as they relate to connecting infrastructure designed for cloud computing. This white paper outlines the results of those reviews and presents Juniper’s conclusions about TRILL.
Juniper Networks 3-2-1 Data Center Network Architecture: Simplifying the Data Center Network to Reduce Complexity and Improve Performance
By Juniper Networks
Today’s data center networks are under tremendous pressure. Not only are they growing geometrically to keep pace with rapidly escalating business demands, support new application architectures and virtualized environments, and improve the overall user experience, they are expected to do so more efficiently and more cost-effectively than ever before.
The problem lies in the fact that, while everything else in the data center (applications, storage, servers) has evolved over time, the network architecture itself has not. Rather than evolve, the data center network has instead become extremely complex. This
complexity prevents the network from scaling properly, restricting available resources and limiting the ability to virtualize the data center. The Juniper Networks 3-2-1 Data Center Network Architecture delivers a strategy for simplifying the data center by flattening the existing multilayer tree structure to improve overall performance as well as the user experience.
Juniper Networks brings its first ever-public tested EX8216 core switch to the Lippis/Ixia test at iSimCity were we test all 128 10GbE links for performance and power consumption. Nick Lippis interviews Ellen Brigham, Director of Product Marketing at Juniper Networks responsible for Data Center products and solutions on cloud network design with Juniper’s EX series of core switches.
