Defining the protection types: Unprotected, Deterministic, and Mesh Protection

Defining CIR

Unprotected Circuit – This means that data traveling from Location A to Location Z has only a single defined path and incase of a cable failure there is no second route for the data to reach its destination.

Deterministic Protection – This means that there are two clearly defined paths or cable routes for the data to reach from Location A to Location Z. In case of a cable failure on one path the data gets rerouted and reaches the destination through the second defined path.

Mesh Protection – This means that there are multiple routes available from Location A to Location Z and the data can travel on any of these routes to reach its destination. In case of a failure on one of the routes the data will be re-routed automatically to one of the other available routes.

CIR is Committed Information Rate. This means that the customer gets the exact committed bandwidth on our network. For example, if the customer buys 10 Meg of bandwidth, we will reserve 10 Meg of bandwidth for the customer on our network.

Defining the MEF service types like EPL, EVPL and EP-LAN etc.

E-Line - Any Ethernet service that is based on a Point-to-Point Ethernet Virtual Connection (EVC) is designated as an Ethernet Line (E-Line) Service type. An E-Line service type can be used to create a broad range of Point-to-Point services.

EPL – An Ethernet Private Line (EPL) service is specified using an E-Line service type. An EPL service uses a Point-to-Point EVC between two UNIs and provides a high degree of transparency for service frames between the UNIs it interconnects such that the service frame's header and payload are identical at both the source and destination UNI when a service frame is delivered.

EVPL - An Ethernet Virtual Private Line (EVPL) is created using an E-Line service type. An EVPL can be used to create services similar to the Ethernet Private Line (EPL) with some notable exceptions. First, an EVPL allows for service multiplexing at the UNI. This capability allows more than one EVC to be supported at the UNI where the EPL does not allow this. Second, an EVPL need not provide as much transparency of service frames as with an EPL. Because service multiplexing is permitted, some service frames may be sent to one EVC while other service frames may be sent to other EVCs.

E-LAN - Any Ethernet Service that is based upon a Multipoint-to-Multipoint EVC is designated as an Ethernet LAN (E-LAN) Service type.

EP-LAN - Subscribers with multiple sites often want to interconnect them at high speeds so all sites appear to be on the same Local Area Network (LAN) and have equivalent performance and access to resources such as servers and storage. Subscribers commonly desire a highly transparent service that connects multiple UNIs. To this end, the Ethernet Private LAN (EP-LAN) service is defined in this subsection, using the E-LAN service type.

EVP-LAN - Some Subscribers commonly desire an E-LAN service type to connect their UNIs in a metro network, while at the same time accessing other services from one or more of those UNIs. An example of such a UNI is a Subscriber site that wants to access a public or private IP service from a UNI that is also used for E-LAN service among the Subscriber's several metro locations. It is defined as the Ethernet Virtual Private LAN (EVP-LAN) service in this subsection to address this need.

What are MEF Certifications?

Metro Ethernet Forum (MEF) is a global industry alliance comprising more than 170 organizations including telecommunications service providers, cable MSOs, network equipment/software manufacturers, semiconductors vendors and testing organizations. The MEF develops Carrier Ethernet technical specifications and implementation agreements to promote interoperability and deployment of Carrier Ethernet worldwide.

MEF certifications are verified through independent testing and assure customers that our global Ethernet services meet rigorous international standards.

MEF 14 ensures that the latency, jitter and packet delivery performance of the services conforms to the rigorous MEF standards.

MEF 9 ensures the conditions required for delivery of services have specific Ethernet User Network Interface (UNI) and Ethernet Virtual Connection (EVC) service attributes, with corresponding parameter values.

MEF 14 and 9 certifications apply to our Global Dedicated Ethernet service, National Dedicated Ethernet Services, Priority Ethernet Service, Multipoint Service and Virtual Private Line Service (VPLS).

Service Details

- SLAs that extend from customer premise to customer premise

- SLA includes service up time, packet delivery, latency, and jitter

- Web-based customer portal for SLA monitoring in near real time

- End-to-end Monitoring

Tata Communications installs network interface devices (NIDs) at the customer premise. Data is collected from the NIDs every five minutes, allowing Tata Communications to deliver constant, end-to-end monitoring of the circuit. In addition to monitoring, this configuration also facilitates rapid diagnosis if network issues occur. This end-to-end capability delivers highly accurate service measurements in line with customer traffic for performance statistics that accurately reflect the customer's traffic flow and experience.

A Service Provider version of this option is available.
