	Fiber Too Expensive? Try EoC As business applications become more and more demanding and dependent on IP and Ethernet protocols, Carrier Ethernet has emerged as the WAN technology of choice for enterprise access. Carrier Ethernet promises an efficient, simple, scalable and cost-effective solution whether you are using it for dedicated internet access, connections to cloud applications, or VPN. Ethernet for business applications is estimated to grow substantially through 2015. Of course, fiber optic connectivity is the preferred method service, but Ethernet over Copper (EoC) has become a strategic choice as well for its competitive price and service. There are a few main reasons why companies may choose EoC, among them : 1. It’s Ethernet. Some new technologies promising broadband service may only be used for internet access or basic voice service. Ethernet meets business-class symmetric service requirements, providing scalable, reliable and manageable features. EoC delivers the service businesses have come to expect. 2. Fiber options may be very limited. Currently only about 30% of businesses have access to fiber. The cost to upgrade is very expensive, and it takes anywhere from 6-18 months to install. Many companies do not want to wait that long, or invest so much money in the service. Most facilities are connected to the legacy copper voice network, which makes it easy to transition to EoC in a matter of weeks. Many providers have found they can increase speeds ten-fold with EoC, which may be enough for most companies. 3. EoC is on par with fiber. Nearly all service providers have multiple service classes, including many premium products, in order to deliver the customer experience your company needs. Most of them are able to provide a service equal to fiber-based Ethernet services. 4. Innovations in technology have advanced EoC capabilities. New generations of EoC edge and aggregation equipment have increased capabilities to over 15 Mbps symmetric per copper pair, and providers can now deploy 200+ Mbps Ethernet. This gives you the service at a fraction of the cost. The popularity of carrier Ethernet for business WAN service creates the demand that can’t be completely met with fiber. Advances in EoC give businesses a good alternative that provides equal service at a fraction of the cost.

	Cloud Network Performance Considerations There are three major factors that can affect performance of Cloud networks ~ Quality (of service), security, and reliability. Not all providers are created equal so be sure you are aware of each of these areas when shopping around. Quality of service ( or QoS) is assured by making sure controls are in place so that appropriate treatment can be applied to packets depending on their importance. QoS metrics help monitor such service elements as traffic profile (e.g., average and peak rate and burst size) and delivery (e.g., delay, delay variation, and dropped and “errored” packets). Security actually has two factors of consideration: that within the cloud itself and at the end user side as devices attach to the cloud. Encryption and authentication protocols must be in place for cloud communications. Reliability of networks is also critical. If your internet access is business critical, this should be important to you. Cloud networks require even higher availability standards than others; adequate communication service management protocols are necessary to assess the performance and health of the structure within the cloud network. More and more cloud providers are building their own networks, but for now many of the cloud service providers do not own the data communications equipment and protocols used in the process. Either way, the industry standards are ever evolving and companies must understand the limits of the technology in order to design a consistent cloud solution.
