Metro Ethernet Networks
Carrier Ethernet was aimed to offer the savings of the Ethernet network to carriers along with guaranteed bandwidth and delivery. With the Metro Ethernet Forum enabling standardization, we have several standards such as PBB and PBB-TE. Since MEF is defining the necessary standards and guidelines for CFM (Connectivity Fault Management) and OAMP (Operations, Administration, Maintenance, and Provisioning), the Metro Ethernet network, is gaining momentum. With standardization, operators can choose different vendor equipment at various levels: from the edge to the core of their network.
Challenges in managing Metro Ethernet networks
A management system is a necessity in Metro Ethernet networks since the networks are designed to compromise the dynamic learning capabilities of Ethernet for a better bandwidth guarantee. A management system must offer the ability to detect the shortest primary and secondary paths, create the necessary tunnels, reserve bandwidth, configure the EVCs (Ethernet Virtual Circuits) based on the service, and create the necessary CFM points (MEP and MIP). All these actions get increasingly complex when the network is populated with equipment from multiple vendors.
Dhyan's solution for managing Carrier Ethernet networks:
Dhyan has added Metro Ethernet service definition and provisioning capabilities to complement the topology and FCAPS capabilities of NetMan as part of its Carrier Ethernet solution. Dhyan's Carrier Ethernet solution has helped device manufacturers get their Carrier Ethernet solution to market faster by capitalizing on the following capabilities.
- Helps the device manufacturer define new service definitions and enables operators to create both E-Line and E-LAN services using a simple two click interface.
- Automatically detects the topology of the network and suggests the best paths using efficient path tracking algorithms.
- Reserves necessary bandwidth within each point and creates the necessary EVC, UNI, MEP, or MIP as per the standard.
- Capitalizes on bandwidth profiles to ensure the service offers a guaranteed QoS for service.
- Monitors service level latency, jitters, and reports their trends.
- Offers the ability to identify services that deteriorate over a period using the trend analysis engine. Also helps the operator resolve them in a proactive manner.
- Assists the roll-out network configuration changes across the network and rollback changes in case of any failures
- Uses logical topology view to complement the Google Maps based deployment view. By using overlays for each services provisioned within the network, operators can make better-informed decisions.
- Helps operators understand the affected services for each node in a network. This is handy during network maintenance windows.
