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.
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).
JUNOS SPACE VIRTUAL CONTROL
2
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.
Virtual Control’s Virtual-to-Physical Mapper and P+V Dynamic
Orchestrator features also fully automate physical infrastructure
provisioning, helping to eliminate configuration conflicts between
virtual and physical networks and increasing the efficiency of day-
to-day network operations.

Integration with VMware
Junos Space Virtual Control integrates with VMware vSphere,
providing access to the VMware vNetwork Distributed Switch
(vDS) framework. Using Virtual Control, users can discover,
manage and monitor the entire virtual network (vNetwork)
inventory consisting of vSphere Hosts, vDSs, and virtual machines
from multiple VMware vCenter Server instances.
Virtual Control efficiently manages vDS Port Groups and Uplink
Port Groups and constantly monitors, logs, and reacts to vNetwork
events to keep track of virtual machine locations in the network.
Virtual Control also allows users to group VMware’s recommended
vDS Port Group best practice settings into profiles; using these
profiles, Port Groups that share best practice settings but have
varying VLAN requirements can be quickly and easily deployed on
different vDSs.
Virtual Control can also be used to discover Port Groups being
managed via VMware vCenter Server. This allows for flexible
operational models that define how management responsibilities
are split between network and server teams. In addition, Virtual
Control enables error free deployment of VMware services such as
VMotion, Distributed Resource Scheduler (DRS), high availability
(HA), and fault tolerance.

Web-Based Interface
Virtual Control uses a Web 2.0 interface to manage both virtual and
physical networks consisting of Juniper devices such as switches,
routers, and security platforms. The application provides a task-
oriented GUI which enables users to complete tasks in congruent
navigation steps and screen flows without context switches.
Junos Space
One of the core members of the Juniper Networks Junos operating
system platform, Junos Space uses the same design principles and
open systems approach as Junos OS to enable programmability at
the network application layer.
Junos Space is a multipurpose application platform designed to
be simple, smart, and open.
• Smart—The core platform provides network abstractions and
automation to enable smart applications, and it includes best
practices to automate repetitive tasks, minimize user input, and
scale services.
• Simple—The platform interface is business intent-oriented, not
technology-centric, with the system guiding the user rather than
the other way around.
• Open—The platform architecture is open and explicitly designed
to enable partners to build and deploy applications that are
smart, simple, and easy to use.

Features and Benefits
FEATURE DESCRIPTION BENEFITS
Collaborative
management
Junos Space Virtual Control supports the following operational models:
1) vNetwork Access Control: Enables the network operator to provision,
define, and deploy end-to-end policies on virtual and physical networks.
Server administrators retain control over virtual machine management
and associating virtual machines with the policies defined by the network
operator.
2) vNetwork Monitor: Gives network operators visibility into the virtual
network, but not necessarily “write” access.
3) vNetwork Cloud: Delivers powerful P+V Dynamic Orchestrator and
vNetwork event monitoring capabilities in cloud deployments where
virtual network infrastructure provisioning is fully automated by cloud
management tools such as VMware vCloud Director.
Provides the flexibility to adopt an
operational model that best fits the
organization.
vNetwork inventory
management
Discovers and constantly updates the complete virtual network inventory,
including vSphere Hosts, virtual switches, and virtual machines, as well as
existing Port Group definitions on the vDS, and presents various views of the
inventory to the network operator.
Oers complete visibility into the current
state of the vNetwork.
Virtual-to-Physical
Mapper
Provides information on connectivity between virtual and physical networks
and the association of virtual switch uplink ports to external physical switch
ports.
Provides end-to-end network view and
simplifies troubleshooting.
VM Locator Ensures that the network operator always knows the current location of each
virtual machine on the vNetwork. The network operator can also shut o
ports to prevent “misbehaving” virtual machines from accessing the network.
Improves operational eciency.
Virtual switch port
profiles
Allows grouping of common networking attributes on virtual switch ports.
Virtual Control supports profiles for VMware vDS Port Groups, enabling the
rapid deployment of Port Groups that share VMware best practices network
settings (QoS, security, network interface card teaming, failover; etc.) but have
conflicting VLAN requirements on dierent vDSs. Profiles can be cloned, and
Port Groups that share a profile can be easily viewed.
P+V Dynamic
Orchestrator
P+V Dynamic Orchestrator constantly monitors vNetwork changes and
automatically provisions the physical network infrastructure to adjust for
those changes.
Orchestration supports “strict” and “very strict” modes. Strict mode
automates the setup of specific network policies (i.e. VLAN) on physical switch
ports spanning a server cluster based on the corresponding configuration
enabled on the vNetwork. This is the “connectivity for cluster” model.
Very strict mode automates the setup of specific network policies (i.e.
VLAN) on physical switch ports spanning a server cluster based on “active”
policies being used by virtual machines in the vNetwork. Policies may be
dynamically reconfigured when a virtual machine changes locations. This is
the “connectivity on demand” model.
Automates physical network setup and
reduces downtime due to configuration
conflicts.
Enables error free and scalable
deployment of services such as
VMware VMotion, Distributed Resource
Scheduler (DRS), high availability, and
fault tolerance.
Oers better network security and
eciency, especially in multi-tenant
deployments.
Configuration audit Virtualized data centers are dynamic environments with frequent changes.
With Virtual Control, network operators can issue configuration audit checks
for the vNetwork as well as the connected physical network. Virtual Control
also generates a detailed audit report and raises alarms whenever an
incorrect configuration aects virtual machine trac.
Allows network operators to be quickly
informed of and react to configuration
faults that could cause outages.
Multiple vCenter server
instances
Discovers and maintains inventory from multiple vCenter server instances to
provide a consolidated network view.
Consolidates management in multi-
tenancy cases.
Event and audit logs Maintains a log of all vNetwork events and automatically records all actions
performed by users in the GUI. Network operators can check and generate
reports on user activity.
Provides historical record of vNetwork
events and user activities.
Non-disruptive
installation
Plugs into existing vSphere installations without disruption. Supports plug-and-play operation with
no service disruption.
Variable form factors Runs on the Junos Space platform, as a virtual appliance on a VMware server,
or on a dedicated Junos Space physical appliance.
Oers the flexibility to adapt to the
organization’s management needs.
Web 2.0 graphical user
interface
Uses a Web 2.0 GUI and is designed to simplify the way network operators
interact with the system.
Supports intuitive, personalized
workflows, real-time network status, and
a statistical dashboard view to improve
operator productivity.
