EtherBurst™ SX-1000
Ethernet Service Node

Driving Ethernet efficiency into optical networks

EtherBurst, with it's vmSwitching™ capabilities, forms a distributed layer-2 Ethernet switch comprised of PX-1000 Photonic Nodes and SX-1000 Ethernet Service Nodes. SX-1000 Ethernet Service Nodes provide one gigabit Ethernet (GbE) and ten GbE interfaces for easy integration into metro and campus network architectures.

SX-1000 Features

The SX-1000 Ethernet Service Node is a modular component of the EtherBurst Packet WDM System. Up to thirty two SX-1000 Ethernet Service Nodes may be connected to a metro ring of PX-1000 Photonic Nodes. Each SX-1000 Ethernet Service Node supports up to two Ethernet modules and up to two TAP modules.

Gigabit and 10 gigabit Ethernet modules
Ethernet IO modules may be mixed or matched in any SX-1000. Both a twenty-four port GbE IO module and a two port 10 GbE IO module are available. Supported Ethernet IO module configurations in an SX-1000 Ethernet Service Node include:

• Twenty-four 1 GbE ports
• Two 10 GbE ports
• Twenty-four 1 GbE and two 10 GbE ports
• Forty-eight 1 GbE ports
• Four 10 GbE ports

160 Gbps Ethernet switch fabric
Each SX-1000 Ethernet Service Node provides 160 Gbps of full duplex Ethernet switch fabric. This enables far greater capability than mere packet grooming. Networks can be oversubscribed with best effort traffic while still insuring the delivery of high-priority traffic and premium service level agreements (SLAs) on the same converged network.

The SX-1000 Ethernet Service Nodes’ Ethernet switch fabric ensures only traffic destined for remote SX-1000s goes to the photonic layer. If the destination for ingress Ethernet traffic is reachable through another port on the same SX-1000, the packet is locally switched to the correct interface without transiting the photonic layer.

TAP modules
Each SX-1000 supports up to two TAP modules. Each TAP module integrates Matisse Networks’ Tango 10 Gbps optical burst transponder and MeshWave packet processor, and adds 10 Gbps of shared bandwidth to the metro network.

SX-1000 Benefits

Maximum utilization of optical bandwidth
Every TAP module deployed adds 10 Gbps of shared optical bandwidth to the metro network. Sharing transponder capacity and re-distributing bandwidth in real time eliminates the stranded bandwidth problem common with circuit-DWDM systems.

Sharing transponder capacity lowers the cost of initial deployment and allows the network operator to focus on meeting bandwidth demand rather than mere connectivity. Shared transponder capacity also enables pay as you grow deployment of metro networks, enabling the network operator to add bandwidth when and where needed. This is vastly more efficient than circuit-DWDM systems that require the deployment of a pair of dedicated transponders even when only sub-rate connectivity is required.

Increased service flexibility
The EtherBurst optical switch recognizes and responds to information carried in Ethernet packets, re-distributing bandwidth in real-time as traffic patterns change. Higher level protocols like MPLS, VPLS and PBB-TE (PBT) map into Ethernet packets, and the EtherBurst optical switch supports all Ethernet service protocols and topologies through intelligent processing of the Layer 2 Ethernet header. This ability to re-distribute bandwidth based on a variety of service protocols enables a future proof transport architecture.

Since EtherBurst provides any-to-any, all-optical connectivity in the metro, multiple concurrent service topologies (tree, point-to-point, mesh) are supported, enabling efficient convergence of a broad portfolio of packet services on a common packet optical transport network.

Lowest total cost of ownership
A recent study by Network Strategy partners shows that EtherBurst delivers the lowest total cost of ownership for metro packet optical transport networks, offering both capital and operational expense savings of 50% when compared with circuit DWDM solutions. The compelling economics of optical burst switching combined with the operational simplicity of the EtherBurst optical switch result in the lowest cost of ownership when scaling metro and campus networks beyond 10 Gbps.
