As the corporate world comes to rely more than ever on
Information Technology 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 Allied Telesis 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.

Scalability
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.

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.

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.

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 using VLAN encapsulation over an EPSR ring,
and deploying Allied Telesis secure LAN switches, this network is
resilient, secure, scalable, and high performing.

As well as providing these core data storage and Internet services,
Allied Telesis 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 video VLAN that is laid across
the physical network. Camera control signalling is also transported
in this same VLAN.

A separate virtual Voice over IP (VoIP) network can also be
provided for multiple tenants, providing them with the many benefits
that advanced VoIP systems have to offer.
