DESIGN GUIDE - Data Center LAN Connectivity Design Guide
Juniper Networks delivers a proven IP infrastructure for the data center that meets these challenges, enabling the
performance, scalability, flexibility, security and intelligence needed to not just meet but increase branch-office user
productivity. Juniper offers flexible configurations and price points that meet the needs of all data centers while
delivering high-performance throughput with services such as firewall, UTM, VPN, MPLS, IPV6 and CLNS-enabled.
Juniper provides an open systems approach that enables enterprises to design a high performance data center
network that consolidates network elements into a single IP network and employs fewer network devices and fewer
layers. This greatly simplifies the network architecture, and enables operational efficiencies and creates better data
center networks.
