NETWORK VIRTUALIZATION

• Network virtualization challenges:
– Dynamic, fluid environment
– Multivendor
– Not designed to be virtualized
– Some workloads run only in physical
environments
CORE

OVERCOME THE CHALLENGES
The six best practices for success:
Establish a solid
foundation
Enable universal
connectivity
Build the shortest
bridges possible
Avoid functional and
performance pitfalls
Use a single security
approach
Use a common network
management platform

4. 4
#1: ESTABLISH A SOLID FOUNDATION
• Ensure the physical network is solid
– Application/location independent
– Fair any-to-any connectivity
– Non-blocking
– Low latency, low jitter, and no packet loss

5. 5
#2: ENABLE UNIVERSAL CONNECTIVITY
– Support inter-, intra- and cross-virtual network communications
– Provide physical and virtual network routing and bridging
– Enable compute resources to move between networks
• Within physical data centers
• Between physical data centers
• Between a physical data center and a cloud environment
• Universal software-defined networking (SDN) gateways
SDN – software-defined network
USG – universal services gateway
VM – virtual machine
vSwitch – virtual switch
WAN – wide area network

#3: BUILD SHORTEST BRIDGES POSSIBLE
– For large pools, gateways should be in upper tiers of the data center
network such as the access tier or the core/aggregation tier
– For multiple virtual networks within a single physical environment, the
gateway should be at the edge routing tier
• Bridges or gateways should be close to the physical resources

Virtual

#4: AVOID FUNCTIONAL AND PERFORMANCE PITFALLS
• Use hardware-based overlay replication to prevent performance and reliability
issues caused by packet flooding
– Offloads broadcast, unicast and multicast packets from the virtual network
– Converts the packets into standard broadcast, unicast or multicast packets
– Packets are then forwarded to their receivers, delivering performance, scale
and reliability

8. 8
#5: USE SINGLE SECURITY APPROACH
• Deploy security policies across entire networks easily and quickly
– Reduce errors and security gaps
– Simplify and eliminate duplication of admin tasks
– Lower overhead costs

9. 9
#6: USE COMMON NETWORK MANAGEMENT PLATFORM
• Single-pane-of-glass management helps identify and arbitrate issues
– Expedites troubleshooting
– Prevents finger pointing
– Ensures consistent behavior across physical and virtual networks

JUNIPER SUPPORTS VMWARE NSX
• Juniper and VMware have partnered to integrate Juniper solutions with
the VMware NSX platform
– Programmatically connects virtual and physical networks
– Delivers L2 gateway services to bridge virtual and physical network environments
– Optimizes NSX deployments for all data center network topologies
