Network Virtualization
Today’s building management companies can derive revenue
from their commercial tenants by providing facilities beyond
just floor space. Reliable and secure network connectivity and
data storage services are now highly attractive to commercial
tenants. However, when your company manages a multiple tenant
building – this could be a shopping mall or office block – how
do you provide these services securely, affordably, and simply?
from their commercial tenants by providing facilities beyond

data storage services are now highly attractive to commercial
tenants. However, when your company manages a multiple tenant
building – this could be a shopping mall or office block – how
do you provide these services securely, affordably, and simply?
They key is to be able to build a single network infrastructure
through the building, and then allow the individual tenants
to overlay their own virtual networks over this shared
infrastructure. Moreover, it is vital that you achieve this
network virtualization securely. Individual tenants need to
be 100% confident that their virtual network is completely
invulnerable to snooping or infection by other tenants.

In addition, to meet your network management needs the
infrastructure must be resilient, scalable, and simple to manage.

Allied Telesis have developed a combination of products and features
that provide remarkably secure, reliable, high-performance virtual
network infrastructure at extremely cost-effective price points.

Virtualisation
The key component in this solution is the standards-compliant
VLAN encapsulation (known as VLAN double tagging or QinQ).
This makes it possible for each tenant to have their own
complete VLAN structure overlaid onto the physical network,
running parallel with every other tenant’s VLAN structure,
even if they are using the same VLAN IDs as other tenants.

running parallel with every other tenant’s VLAN structure,
even if they are using the same VLAN IDs as other tenants.
Each tenant is assigned a unique encapsulating VLAN, which forms
their own virtual tunnel right across the whole shared network.
On the shared segments, each tenant’s data runs within its own
tunnel, completely separated from anyone else’s data, with no
possibility of cross-over from one virtual network to another.

Resilience
Allied Telesis premium ring resiliency technology, Ethernet Protected
Switching Ring (EPSR), has been developed and hardened in
demanding Service Provider and Telco sectors. This technology
provides true carrier-class network resiliency, and has been made
available on Allied Telesis switches at an Enterprise-level price point
with absolutely no drop in reliability or performance.

demanding Service Provider and Telco sectors. This technology
provides true carrier-class network resiliency, and has been made
available on Allied Telesis switches at an Enterprise-level price point
with absolutely no drop in reliability or performance.
The layout of typical commercial premises, such as office blocks,
shopping malls, and airports, lends itself to the use of a core ring of
switches as a high-speed backbone of the network infrastructure.
This highly resilient network technology is perfect to overlay
multiple virtual networks for many tenants or clients, where
everyone benefits from the maximum network uptime and high
bandwidth provided.

Other features such as excellent network storm control and
prioritisation of network control traffic also contribute to creating
extremely high network availability. Add switch hardware features
like dual hot-swappable power supplies, and continuation of services
is all but guaranteed.

Security
Allied Telesis switches combine leading LAN security with
comprehensive privacy protection to ensure complete
security for end-customers who virtualize their LANs
over a shared physical infrastructure. More information

The IP-binding and Private VLAN (using MAC-Forced Forwarding)
implementations in Allied Telesis products have been developed
to meet the stringent user privacy and data security requirements
of Service Providers. Private VLANs ensure that no traffic from a
switch port can be seen from another switch port. The addition
of MAC-Forced Forwarding adds further security by sending
all traffic only to a specific known destination, making snooping
on your neighbour near impossible. Commercial tenants can
be fully confident that their privacy and security is ensured.
