Performance  
Scalability  
As the corporate world comes to rely more than ever on  
InformationTechnology resources and applications, a high  
performance, high availability infrastructure is vital. An EPSR ring at  
the core of the network provides these performance benefits:  
The flexibility of the SwitchBlade x908 and x900 series switches  
makes network expansion incredibly simple.The modular chassis  
design, coupled with the hot-swappable interface modules, mean  
that it is possible, for example, to upgrade the bandwidth of the  
core ring with absolutely ZERO downtime.  
High bandwidth:An EPSR ring can run at up to 10Gbps (or  
multiples of 10Gbps), utilizing today's fastest Ethernet standard  
for maximum data throughput.  
Similarly, as client device numbers increase, new sets of client-  
facing ports can be hot-swapped into the chassis, and new clients  
connected, with no service disruption.  
Immediate access: Seamless connectivity via voice, video, or  
email is maintained, and network servers are accessible with no  
delay.  
The advanced design of the switching hardware provides a platform  
that will not be obsolete for many years to come.The hardware is  
already completely IPv6 capable.The Layer 2 and Layer 3 forwarding  
table and hardware ACL table capacities are measured in the  
thousands – this is a platform that is well able to support major  
network and service expansions, and network technology advances.  
High availability:With no single point of failure, continuous  
access to critical business data and network resources is  
maintained.  
Application versatility: High bandwidth and ultra-fast failover  
lend themselves to multiple applications simultaneously using  
the network. Real-time applications like surveillance, video  
streaming and voice over IP can be used right alongside data  
and Internet access.  
Solution overview  
The virtualization of a single physical network infrastructure (seen  
in Figure 1) can provide a real private network for a number of  
different tenants. By usingVLAN encapsulation over an EPSR ring,  
and deploying AlliedTelesis secure LAN switches, this network is  
resilient, secure, scalable, and high performing.  
The AlliedTelesis SwitchBlade x908 and x900 series switching  
fabrics provide extremely powerful and reliable forwarding engines  
over which to lay the network infrastructure. All Layer 2 and Layer  
3 forwarding, traffic filtering, data encapsulation, traffic prioritization,  
and network storm protection are carried out at wire-speed on all  
interfaces with low latency.  
As well as providing these core data storage and Internet services,  
AlliedTelesis switch technology allows you to make additional  
services available to tenants.  
A combination of a Power over Ethernet (PoE) access layer with  
the high-speed shared core is ideal for having a video surveillance  
network overlaid on it. Multicast streams from multiple cameras  
attached to diverse locations on the network are carried back to a  
central control centre via a dedicated videoVLAN that is laid across  
the physical network. Camera control signalling is also transported  
in this sameVLAN.  
A separate virtualVoice over IP (VoIP) network can also be  
provided for multiple tenants, providing them with the many benefits  
that advancedVoIP systems have to offer.

Summary  
By ensuring always-available online applications and resources, and total security of data for tenants, building management companies can  
offer advanced network technology solutions to prospective tenants as a real value-added service.The addition ofVoIP phone systems and  
video surveillance for building security simply makes the value proposition offered outstanding.  
Tenants receive the best in leading edge networking and data services without the large capital outlay required to build a complete physical  
network themselves.They can also be confident in their choice of location, with leading-edge IP multicast building security ensuring 24/7  
surveillance of their premises.
