E-Tree Point-to-Multipoint

Ethernet Virtual Connection (EVC)


MetroTree is an E-Tree Ethernet Virtual Connection (EVC) Point-to-Multipoint or Rooted-to-Multipoint product providing Ethernet Private Tree (EP-Tree) and Ethernet Virtual Private Tree (EVP-Tree) network connectivity for multi-host and franchised applications where user traffic must be kept invisible to other users.

MetroTree™ is available from 1Mbps to 10Gbps bandwidth speeds with 3 Class of Service Options  - Basic, Priority Data and Real time.  MetroTree™ provides traffic separation between users with traffic from one “leaf” being allowed to arrive at one or more “Roots” (one being a redundant Root) but never being transmitted to other “leaves”.  MetroTree™ EP-Tree is the “Port- Based” E-Tree Rooted-to-MultiPort service configuration that enables all to- one bundling of all customer VLAN’s (4096) into a single EVC per UNI port.  MetroTree™ EVP-Tree is the Rooted-to-MultiPort “VLAN Based” E-Tree Service configuration that enables customer VLAN’s to be Service Multiplexed into two EVC per UNI port.

MetroTree™ EVP-Tree adds a Second any to any application. MetroTreeTM provides full port native Ethernet LAN speeds of 10 Mbps, 100 Mbps, 1 Gbps and 10Gbps with 3  Class of Service options - Basic, Priority Data and Real Time.

For Packet Voice (VoIP) and Video applications, Real Time is offered on a per-UNI basis and is designed to support Packet Voice and Video applications over a Rooted Point-to-MultiPoint service.


Is for the end-user data applications that require no guarantees of performance and where cost per Mbps is the key requirement.

Priority Data

Is for the end-users a data application requiring a bandwidth guarantee and Latency is not a requirement.

Real Time

Is for end-users requiring low delay (Latency) for some of their traffic and is an ideal service class for packet voice (VoIP) and Video applications.

A persistent question of users and network operations is how well is the network operating? Quick, consistent transport of traffic across the network is very important. Customers are demanding that Service Providers maintain more stringent network performance of which are formalize with Service Level Agreements (SLA's). 

Here at Metrofibre networx our Service Level Agreements (SLA’s) have been specifically designed to ensure customers uptime of the network and the end-to-end service traffic performance. 

Performance Assurance 

For best traffic performance assurance guarantees, we track and measure the performance of traffic transiting across the entire Metrofibre networx, from customer interface to customer interface, with our Network Performance Management system that collects, monitors and measures end-to-end service performance for each MetroTreeTM Class of Service (CoS) priority provisioned (Basic and Real Time).

Our MetroTreeTM is monitored centrally at our state of the art Network Operations Center (NOC) to the MEF pre-defined CoS Service Performance parameter thresholds (See below).

Network-Uptime Assurance 

For the best network-uptime assurance guarantees, we ensure that our network designs have sufficient resiliency built-in to meet the most stringent of Service Level Agreements.
