DESIGN SCENARIO - Case Study Example

Metropolitan- area Ethernet also known as metro Ethernet refers to a MAN (Metropolitan Area Network) which is based on Ethernet standards. Mainly, it’s used to connect subscribers to a larger service network. Also, this network can be used by businesses network administrators to connect offices to each other. This service is offered by a wide range of service providers including Comcast. This service is mainly preferred due to its advantages.Metro Ethernet is easy to use. This service is provided over a widely available, well understanding and standard Ethernet interface.

In this type of metropolitan Area Network, all networking equipment are virtually hosted and connected to the network using Ethernet. Thus using the Ethernet to interconnect such services makes it easier for network operations, administration, and management and provisioning. Comcast is using this advantage of Metro Ethernet to attract more customers in California and its environs. As a result, more subscribers are joining this service.The Comcast metro network service is cost effective. Metro Service has characteristics that favor its cheap service.

Metro Ethernet service has broad usage in all networking products. The inexpensiveness of the Ethernet interface makes it cheaper in all networking services. Secondly, the cost of equipment, service and operational is cheap. This makes Ethernet services to be cheaper. Comcast allows its subscribers to add bandwidth more incrementally; as a result each customer purchases the bandwidth according his / her use. Comcast has sub - divided its services into three classes. These classes offer different services at different bandwidth.

These are premium, basic and priority. These services are offered in 10 Mbps, 100 Mbps, and 10000 Gbps to Ethernet users and these interfaces and are available in an increment of 1Mbps to 10Gps.The Ethernet service provided by Comcast has the following specifications. It has Ethernet user – to – network interface. This service facilitates provision of bidirectional, full duplex transmission of Ethernet frames using standard IEEE 802.3 Ethernet interface (Comcast, 2013). This service supports up to 100 UNIs.

Comcast manages its network by restricting traffic flow of a subscriber to the amount subscribed. In case the customer exceeds it’s the subscription rate, the traffic is discarded.
