Today’s networks, built on top of Ethernet, IP and MPLS services, require an
emulation solution that combines high-performance, flexible network modeling,
test automation and integrated application analysis. Shunra’s family of VE Network
Appliances continue to lead the market with high-performance, scalable WAN
emulation that brings the behavior of a production network into a controlled lab
environment. A VE Appliance can help ensure service levels are met as applications
scale and complexity increases on your production network.
Whether you’re managing a significant Data Center Consolidation project, planning
the deployment of a business-critical application or adopting WAN Optimization
technology, including network behavior in your application performance testing
has become a critical success factor.
Shunra offers appliances that range from several 10/100 Ethernet interfaces up
to the latest STA appliance supporting 10Gbps service interfaces and a switching
capacity up to 24Gbps. Shunra’s WAN emulation appliances can function in an “east
west” tunnel mode; its unique switching architecture also supports flexible network
topology emulation providing any-port-to-any-port Layer 2 switching, VLAN
Trunking, Layer 3 Routing; and it provides built-in, intelligent packet capture buffers
that enable application analysis.
All Shunra VE Network Appliances support a user-friendly GUI for WAN emulation
testing, and several teams can share a single appliance and run independent
emulations in parallal. Shunra’s award-winning Virtual Enterprise Suite software
provides easy-to-use network modeling, test automation with industry-leading load
tools and integrated application performance analysis.
