ROME Fabric



Design & Build Dynamic Physical Network Fabric

ROME® enables a dynamic physical network via its optical switching capability that has never been achieved before. It’s Wave2Wave’s complimentary engineering service to our customers and partners to design ROME’s to the right network configuration with the best cost efficiency, scalability and manageability.


Although a CLOS network architecture is often a good mathematical starting point for any network fabric design, a custom tailored professional service from Wave2Wave takes the design a step further. It’s beneficial to customers for us to understand their applications in terms of topology, traffic pattern, port speed and sub-domains of network.


Wave2Wave’s professional service also takes design to implementation with logical port mapping as well as cabling with specific labeling and custom cabling. The data file will feed to the network orchestration software for end to end network integration.

A Tailored 3-Stage CLOS Fabric Design

ROME consists a double matrix structure, which can be considered as a tandem switch sharing the same chassis and robotic systems. The double matrix structure is referred as alpha or A, and beta or B.


Knowing the sub-domain of a network is beneficial to build the network fabric with higher port utilization and higher efficiency.

This example shows a two stage ROME fabric with each of the switching, routing and security domain, while 3-stage cross bar ROME switches provide necessary cross connects in between the domains.

In our 1,800 rack data center, we used the concept of zones and pods to build up our equipment pool.

This helps us with a structure and a pass for migration to full automation in a phase by phase approach.

ROME Design for PoD

A point of delivery (PoD) design allows self contained network and compute resources for data center build-out. It could also be a virtual segmentation of set of devices and connectivity to enable better scalability and manageability.


A shipping container is often the physical form factor of a PoD, which allows fast deployment and autonomous operations. ROME enables the reconfigurability of a PoD, so to minimize the footprint and maximize the utilization of capital equipment.

ROME for Optical Long Haul Redundancy

For telco operators, an optical long haul circuit carries large amount of traffic and the service is tied with stringent service level agreement (SLA). Network downtime results in loss of business and penalties. In the meantime, telco operators have to deploy large amount of protection circuits, often 1+1 or 2 for 1. This doubles or triples network CAPEX spending and translates much higher cost to customers.


ROME creates a dynamic protection sharing scheme and increases availability by multiple levels.

A dynamic physical layer significantly improves resiliency of mission critical networks.
