MPLS/VPLS for Data Center Interconnect
Data Center LAN Migration Guide
The consolidation of network services increases the need for Data Center Interconnect (DCI). Resources in one data
center are often accessed by one or more data centers. Different business units, for example, may share information
across multiple data centers via VPNs. Or compliance regulations may require that certain application traffic be kept
on separate networks throughout data centers. Or businesses may need a real-time synchronized standby system to
provide optimum HA in a service outage.
MPLS is a suite of protocols developed to add transport and virtualization capabilities to large data center networks.
MPLS enables enterprises to scale their topologies and services. An MPLS network is managed using familiar protocols
such as OSPF or Integrated IS-IS and BGP.
MPLS provides complementary capabilities to standard IP routing. Moving to an MPLS network provides business
benefits like improved network availability, performance, and policy enforcement. MPLS networks can be employed for
a variety of reasons:
• Inter Data Center Transport: To connect consolidated data centers to support mission critical applications. For
example, real-time mainframe replication or disk, database, or transaction mirroring.
• Virtualizing the Network Core: For logically separating network services. For example, providing different levels of
QoS for certain applications or separate application traffic due to compliance requirements.
• Extending L2VPNs for Data Center Interconnect: To extend L2 domains across data centers using VPLS. For example,
to support application mobility with virtualization technologies like VMware VMotion, or to provide resilient business
continuity for HA by copying transaction information in real time to another set of servers in another data center.
The MX Series provides high capacity MPLS and VPLS technologies. MPLS networks can also facilitate migration
towards a simpler, highly scalable and flexible data center infrastructure.
Juniper’s Unified Management Solution
Juniper provides three powerful management solutions for the data center LAN via its NSM and STRM Series platforms,
as well as Junos Space.

Network and Security Manager
NSM offers a single pane of glass to manage and maintain Juniper platforms as the network grows. It also helps
maintain and configure consistent routing and security policies across the entire network. And NSM helps delegate
roles and permissions as well.
Delivered as a software application or a network appliance, NSM provides many benefits:
• Centralized activation of routers, switches, and security devices
• Granular role-based access and policies
• Global policies and objects
• Monitoring and investigative tools
• Scalable and deployable solutions
• Reliability and redundancy
• Lower TCO
