What isEVPL

Ethernet Virtual Private Line (EVPL) is a data service that provides point-to-point and multiple EVCs between dedicated UNIs, designed to provide a high-performance, secured link with minimal packet loss, low latency, and high quality of service. It offers flexibility and scalability for WAN connectivity to connect multiple offices, data centers, and cloud infrastructures. EVPL is similar to Ethernet Private Line (EPL) but uses virtual links that can be multiplexed to connect multiple EVPL circuits. Unlike traditional private line services, EVPL pricing is not distance-based, making it ideal for remote sites and global networks. Service providers use Metro Ethernet to provide broad access to customers in the region, offering a cost-effective, fast, and secure method to scale or upgrade a network.

FAQ about Ethernet Virtual Private Line (EVPL)

Understanding the ins and outs of EVPL can be a daunting task. Here are some frequently asked questions to help clear things up:

WHAT is Ethernet Virtual Private Line (EVPL)?

Ethernet Virtual Private Line (EVPL) is a data service defined by the Metro Ethernet Forum (MEF) that provides point-to-point and multiple EVCs between a pair of dedicated UNIs. EVPL is similar to Ethernet Private Line (EPL) in that it offers the simplicity of private connections combined with the flexibility and scalability of MPLS technology across multiple bandwidths.

What are the key differences between EVPL and EPL?

The main difference between EVPL and EPL is the configuration required. EPL provides a point-to-point connection between two locations, while EVPL can connect multiple sites in a point-to-point or multipoint configuration. Additionally, EVPL uses a virtual link that can be multiplexed to connect multiple EVPL circuits together, whereas EPL does not.

What are the benefits of EVPL?

EVPL circuits are typically used for wide area network (WAN) connectivity to connect multiple offices, data centers, and cloud infrastructures on a single network. The service offers minimal packet loss, low latency, and a very high quality of service (QoS). EVPL pricing is not based on distance, making it ideal for remote sites and global networks.

What is the difference between EVPL and MPLS?

EVPL is a service that sits on top of MPLS technology, meaning it offers the same flexibility and scalability as MPLS. However, EVPL is a Layer 2 service while MPLS is a Layer 3 service. This means that EVPL is better suited for LAN extension and metro Ethernet services, while MPLS is better suited for WAN connectivity.

What are some common use cases for EVPL?

EVPL is ideal for enterprises that need to connect sites in a point-to-point or multipoint configuration. For example, a company may use EVPL to connect their main office to satellite offices or to connect to a cloud service provider. EVPL is also commonly used to connect geographically dispersed data centers.

The gist

Ethernet Virtual Private Line (EVPL) is a powerful and flexible service that offers high-speed virtual network connections with minimal packet loss, low latency, and a very high quality of service. Understanding the difference between EVPL and Ethernet Private Line (EPL) is important, as is understanding the benefits of EVPL compared to other technologies such as MPLS. Ultimately, EVPL is a great choice for enterprises that require fast, secure, and reliable connectivity between multiple sites.
