Performance

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:

■■ 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.

■■ Immediate access: Seamless connectivity via voice, video, or email is maintained, and network servers are accessible with no delay.

■■ 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.

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.

Figure 2 shows VoIP and Video surveillance virtual networks overlaying the physical network infrastructure.

The Allied Telesis SwitchBlade, x908, x900 specifications

The Allied Telesis x908 and the SwitchBlade x900 series of network switches are cutting-edge solutions designed to address the demands of modern networking environments. These switches are known for their high performance, reliability, and robust feature sets, making them ideal for enterprise and service provider networks.

The Allied Telesis x908 series consists of modular and chassis-based systems that can accommodate a variety of network configurations. One of the main features of the x908 series is its ability to offer high scalability with support for a large number of ports. This makes it suitable for data centers and large enterprise networks where space and bandwidth optimization are critical.

In addition to scalability, the x908 series supports advanced Layer 2 and Layer 3 switching capabilities. This allows for efficient traffic management and routing, ensuring that data is delivered swiftly and reliably. The x908 also incorporates intelligent features such as Quality of Service (QoS), which prioritizes critical network traffic, ensuring that time-sensitive data—like voice and video—maintains its quality during transmission.

The SwitchBlade x900 series takes this functionality further with its innovative modular architecture. This allows organizations to configure their networks to meet specific needs by choosing from a variety of interface cards and service modules. The SwitchBlade x900 also supports advanced security features such as Access Control Lists (ACLs) and VLAN segmentation, which provide enhanced protection against unauthorized access and network threats.

Another hallmark of the x908 and SwitchBlade series is their support for high-speed Ethernet technologies, including 10G and 40G Ethernet. This enables organizations to keep pace with the increasing bandwidth demands of applications and services, particularly in cloud computing and data-intensive workloads.

Both the x908 and the SwitchBlade x900 series are designed with energy efficiency in mind, featuring power-saving technologies that reduce overall operational costs. Coupled with Allied Telesis' management tools, which provide detailed analytics and monitoring, network administrators can optimize performance and energy consumption simultaneously.

In summary, the Allied Telesis x908 and SwitchBlade x900 series offer a comprehensive suite of features, high performance, scalability, and advanced networking technologies. They represent a strategic investment for organizations looking to build resilient, efficient, and future-proof network infrastructures.
