• Eliminates the need for QoS as service
• No coordination needed to make any LAN or WAN changes.
• Voice and Data don’t share bandwidth. Each has their own separate connection.
• Simplified flat network topology
• We deliver 1 GIG of Bandwidth to each location. We rate limit based on your subscribed speed.
• Easily Scalable
• More cost Effective

Positioning Statement
data services are vital to the success
of the modern enterprise. Data-driven
applications require varying degrees of
quality of service at a price point that the
time now, cost and complexity are often a
pain point. Ethernet services increasingly
and cost-containment are of paramount
concern, especially where large bandwidth
is demanded (and IP/MPLS service can
be particularly expensive). In addition,
where SD-WAN strategies are envisioned,
Ethernet can provide a viable and reliable
alternative to pricey data services while
still remaining a dedicated infrastructure
addressing security and reliability
concerns of the enterprise.

SERVICE COMPARISON ETHERNET SERVICES IP/MPLS SERVICES
Layers and transport
Ethernet relies on layer � techniques (Ethernet) to forward IP/MPLS relies on layer � (IP) techniques to forward
Service separation
Usually uses VLANs or stacked VLANs (QinQ for example)
to distinguish customers, service types and individual
services
Usually uses labels to distinguish customers and/or
services into distinct paths through the network
Bandwidth delivery Can range from < �Mbps to ���Gbps
As a service, becomes quite cost prohibitive above
�Gbps
Cost
Usually lower, attributed to simplicity of operations and
“plug-and-play” characteristics
Varies with bandwidth and features required for QoS.

SLA capability SLA-capable with engineered capacity, latency and jitter SLA-capable with engineered capacity
Application: Mobile Backhaul Simplicity, less need for routing or advanced features

Consider Comcast Business SD WAN
With SD-WAN from Comcast Business, companies can retake control of their network by
business opportunities. SD-WAN provides enriched network visibility, with application-level

SD-WAN helps put actionable insights at the center of your wide-area networking strategies.
SD-WAN puts the architecture in place that allows you to do more with your network. Paired
with gigabit speed broadband connections from Comcast Business, SD-WAN can help
overcome the bandwidth, scalability, and cost concerns common with legacy, T�-based MPLS
