COMCAST was started by a small family owned business in 1963 and has grown into a monolith juggernaut corporation. Over the last few months the company has begun to explore SD-WAN (Software-Defined WAN) technologies. Due to the high cost and overhead of traditional TDM and MPLS connections SD-WAN is exploding in the middle to large enterprise space. The company is behind the curve as CenturyLink has already started trialing SD-WAN with beta customers.

Operating an extensive 141,000 miles of fiber network COMCAST has a major presence in the state of Washington. Their large fiber ring stretches from Seattle to Spokane and back. They boast the largest fully 40G backbone and the deployment of the first 100G router interface in the U.S. As of this writing they were still finishing up the deployment of a 100G network. The core network foundation is MPLS (Multiprotocol Label Switching) technology, utilizing Layer 2 IP routing CoS/QoS service. With the introduction of SD-WAN in the future, MPLS deployments may slow.

What use to take minutes with broadband, now only take seconds with Wideband. COMCAST offers Wideband on business lines at, or above, 50 Mbps.

COMCAST Metro Ethernet Services

Ethernet Network Service (ENS) allows customers to connect physically distributed locations across a Metropolitan Area Network (MAN). Your business plugs in a Layer 2 network on one side and BAM on the other side your layer 2 network appears. This was at one time accomplished using the T-1, T-3 style carrier grade services, but now is offered on fiber with Ethernet. Today, using Ethernet companies can not only hit point to point, but also point to multi-point using MPLS.

COMCAST Announces DOCIS 3.1

Robert Howald, Comcast’s vice president of network architecture, has revealed that the company is hoping to upgrade its entire cable network footprint with DOCSIS 3.1 technology within the next two years. CableLabs, the company that designed the DOCSIS 3.1 standard, previously indicated that the 3.1 standard can transmit data at speeds of up to 10Gbps, although Howald notes that end-users can expect to experience more modest speeds of 1Gbps in the first instance.
