CityLink uses a variety of technologies to deliver service to our customers. Our goal is to always attempt to deliver service over our own fiber optic network. In cases were that is not possible we will use a strategic partner/carrier to deliver the service.
Much of our network is developed used well proven Open Source and Open Standards technologies. These technologies include, Linux, FreeBSD, Apache, Nagios, PHP, MySQL and other well known systems.
Our core Layer 3 network is a redundant cluster of Cisco Catalyst 6513 with multiple 10Gig interconnects within the core. We make use of BGP routing protocol to announce our routes to various carrier providers. We can experience a multi-carrier outage and continue to provide connectivity to our customers.
Our core Layer 2 network is a combination of Cisco and Foundry fiber and copper switches. These switches are connected to the core via GigE and 10GigE links.
Our Layer 1 Fiber Optic network is designed as a Ring and provides for a redundant optical path should a fiber-cut be experienced. In the 9 years our Albuquerque Fiber network has operated there has been only 1 fiber cut. No other carrier can make that claim in Albuquerque.
Our Fiber Optic network is deployed using various technologies, including, micro-trench, robotic deployment (storm drain, sewer, etc), directional boring and finally open trenching.
We manage the tools in our tool bag so that we constantly deliver highly reliable services, while managing our operating costs to maintain profitability.
