JUNOS SPACE VIRTUAL CONTROL
DATASHEET
Product Overview
The proliferation of virtual switches
in the data center has presented data
center operators with a significant
challenge—namely, how to manage
these virtual network elements in
conjunction with the physical network.
The tools that network operators
currently use to manage their physical
infrastructure provide no access to, or
visibility into, the virtual infrastructure.
Junos Space Virtual Control unifies
physical and virtual infrastructures,
providing network operators with a
comprehensive view into the complete
end-to-end network. Using Virtual
Control, network operators can manage,
monitor and control both virtual and
physical networks through a single pane
of glass, ensuring that network policies
are consistently and automatically
applied across the infrastructure. This
enables error free network operations
and simplifies the deployment of value-
added services such as virtual machine
live migration (e.g., VMware VMotion).
Product Description
Juniper Networks® Junos® Space Virtual Control allows users to manage, monitor, and
control the virtual networks that run within virtualized servers deployed in the data
center. Built on Junos Space, an open, extensible platform for developing and hosting
applications designed to reduce cost and complexity while opening networks to new
business opportunities, Junos Space Virtual Control contributes to a comprehensive
solution that extends across the routing, switching, and security infrastructure.
Rather than rebuild the virtual switch that comes as part of the hypervisor software,
Virtual Control integrates with the hypervisor vendor’s existing management tools,
delivering a combined solution that benefits from both vendors’ innovation and Juniper
Networks’ orchestration solutions.
The Challenge of Server Virtualization
Server virtualization allows IT organizations to collapse multiple physical servers
onto virtual machines running on a single host using software called a hypervisor. The
hypervisor provides the physical resource abstraction to virtual machines deployed on the
host, while virtual switches provide connectivity between virtual machines residing on the
same host.
These virtual switches blur the lines of responsibility between traditional network,
security, and server teams. Virtual switches require a different set of management tools
than physical switches, making it difficult for network operators to obtain a consolidated
and consistent view of the entire network. Since the physical network must be in sync
with the virtual network to provide the connectivity services required by applications in a
virtual environment, this lack of visibility hampers the network operator’s ability to ensure
smooth operations in virtualized data centers, especially when dynamic events such as
virtual machine live migration are taking place.

Junos Space Virtual Control addresses these problems by
providing network operators with an open, scalable and unified
policy-based solution for managing both virtual and physical
networks. By implementing a collaborative management
paradigm, Virtual Control enables flexible operational deployment
models and management handoffs between network and server
teams, depending on the policies and needs of the organization, to
ensure maximum business agility.
