Experience secure, scalable and cost-effective Ethernet multipoint connectivity with TPG's e-LAN. This solution allows geographically dispersed locations
to easily interact and share business critical information, and is delivered over TPG's MPLS core network.
TPG's e-LAN provides:
  • The ability for you to completely manage your own routing schemes and CPE (Customer Premises Equipment)
  • The control and performance of a Layer 2 VLAN service. With meshed multi-point and secure networking at Layer 2 you can experience the increased
    performance that a non-routed network offers, coupled with maximum bandwidths of up to 10Gbps
  • Quality of Service (QoS) options to ensure critical data is delivered within expected performance parameters, making TPG's e-LAN suitable for the most
    demanding enterprise requirements including voice and video conferencing applications.
TPG's e-LAN includes complete Layer 3 protocol transparency and is certified by the international Metro Ethernet Forum for compliance to their standards
(MEF 9 and MEF 14 listed under TPG's subsidiary AAPT).



Each connection is given a unique encapsulation ID
to create an ePipe that encapsulates all data and runs
across TPG's private backbone.

High performance

Access speeds from 512K to 10Gbps (and higher in some
locations), depending on Access technology and location.

Comprehensive reporting

Web-based reporting on availability, adherence to QoS profiles,
latency, jitter and packet loss.

Quality of Service (QoS)

Intelligently prioritise your traffic with 6 Classes of Service (CoS)
available in 4 Quality of Service (QoS) packages:
1. Best Effort (BE) Only: all traffic is carried in the Best
Effort CoS
2. Business Data (BD) Only: a simple business-grade CoS
providing delivery assurance
3. Simple QoS: Access to all 6 CoS, with a combination of
pre-determined priority queuing and weighted round-robin
traffic handling
4. Flexible QoS: flexible customer defined bandwidth per CoS

Parameter Specifications
Configuration Multipoint (full mesh)
Transport Technology MPLS Core with various Access technologies
Access Networks Fibre400
Mid-Band Ethernet
Ethernet over SDH
Ethernet over Fibre
Third party Ethernet and Business DSL Access
Bandwidth 2Mbps-10Gbps
Bandwidth will depend on the Access speed
Quality of Service (QoS) 6 Classes of Service (CoS) available in 4 Quality of Service (QoS) packages:
1. Best Effort: all traffic is carried within the Best Effort CoS
2. Business Data: all traffic is carried within the Assured Delivery CoS
3. Simple: Access to all 6 CoS minus the complexity of defining traffic contracts for each
4. Flexible: fully flexible customer defined traffic contract per CoS
QoS package is specified per site
Simple and flexible QoS packages require customers to mark traffic (802.1p or DSCP)
Multicast e-LAN services support Unicast, Broadcast and Multicast traffic. Broadcast traffic is throttled
at 256Kbps per site and Multicast traffic is throttled at 2Mbps per site. Customers requiring
greater control over their multicast traffic can choose the optional enhanced multicast capability
to have their e-LAN IP PIM enabled.
MAC Learning Limit The maximum number of unique MAC addresses per e-LAN is 250
Ethernet Frame Size (MTU)1 Fast Ethernet interfaces: 1531 bytes
Gigabit Ethernet interfaces: 8960 bytes
10 Gigabit Ethernet interfaces: 8960 bytes
VLAN Transparency1 Customer VLANs are supported transparently2
Protocol Transparency1 Layer 2/3 protocols are supported transparently3
Site Requirements Rack space (1RU) and 240V AC 50Hz power to be provided by the Customer
Security Ethernet VLL ePipe based on RFC 4447 and RFC 4448
Reporting Access Availability
and Performance Reporting
Optional per site QoS reporting
MEF Certification MEF 1.0 (MEF 9 and 14) listed under TPG subsidiary AAPT
1 Access network dependant
2 Where delivered via Ethernet Trunk Access the customer's equipment must support VLAN stacking
3 Where delivered via Ethernet Trunk Access the customer must tunnel Layer 2 control protocols
