Ethernet

Port types (standard interfaces supported):

Arelion’s Ethernet solution supports jumbo frames up to 9100 bytes acrossour MPLS backbone network.

Layer 2 control protocol transparency requirements are fully supported on Arelion’s network and include last mile access with our Advanced Ethernet option, where a NID (Network Interface Device) is installed at customer site to terminate the service. We configure the NID in tunnelling mode which enables Layer 2 control protocol transparency.

For our Basic Ethernet option which does not include a NID device, Layer 2 control protocol transparency can be validated on Individual Case Basis (ICB) for both on-net and last mile requirements.

Arelion has also introduced a very strict process for onboarding last mile thirdparty access providers. This means that all our supplier partners need to go through a rigorous certification process, although not all of them are able to provide last mile support for jumbo frames. However, if this is a customer requirement, Arelion will endeavour to source an appropriate supplier at the time of order.

Arelion's MPLS backbone offers built-in resilience and 99.999% backbone availability for any services running acrossit. Protecting customer traffic from network faults and fibre cuts provides additional peace of mind.

In addition, for the Ethernet services, we offer twolevels of service availability:

• 99.99% PoP to PoP availability for our Basic Ethernet product where customers do not require managed network interface devices (NIDs). For the purpose of SLA measurement, the demarcation point of the service is the customer-facing port on the Arelion aggregation switch or router in Arelion's MPLS PoP - excluding any cross connects or 3rd party access tails

• For our Advanced Ethernet product with a network interface device, we offer 99.5% end-to-end availability. NIDs are usually located at a customer's premises and the service levels typically apply between these devices. For the purpose of SLA measurement, the service demarcation point is the LAN-side port on the NID, including any cross connects, 3rd party access tails and the device itself

We have designed our core MPLS backbone network for low latency applications, and we offer latency SLA commitments for EVPL and ELAN Ethernet services in accordance with figures published on our portal. For standard configurations, the SLA applies to both primary and secondary paths.

Yes - Arelion Ethernet Services are MEF 3.0 certified: MEF Services Certification Registry. We follow industry standards to make it easy for our customers to implement and deploy our suite of Ethernet products. Additionally, we offer design flexibility for different topologies.

Our EVPL service provides point-to-point or hub-and-spoke configuration options in line with MEF E-Line EPL and E-Line EVPL definitions in Port-Mode or VLAN-Mode configurations. The Arelion EVPL service with Port-Mode UNIs provides a compliant EPL service with partial L2CP transparency on certain routes. L2CP transparency may be requested as an option and can be configured when the Advanced Ethernet service, including a NID, has been ordered by a customer.

Our ELAN service provides any-to-any configuration in line with MEF ELAN EP-LAN and ELAN EVP-LAN definitions in Port-Mode or VLAN-Mode configurations.

For Wholesale customers who have an ENNI with Arelion, we offer E-Access services with handover on the ENNI UNI.

Ethernet services can be provided over circuit switched technologies such as SDH, orpacket switched technologies like MPLS.

Circuit switched networks such as SDH require dedicated physical point-to-point connections - supporting EPL (Ethernet Private Line) point-to-point topology. These are more susceptible to fibre cuts and other network related failures.

MPLS is a protocol for efficient network traffic flow between multiple locations - it uses label switching for fast data forwarding and routing within a network.

The main benefit of MPLS networks is reliability and the primary benefit of Ethernet is affordability and simplicity.

Ethernet over MPLS facilitates transparent Layer 2 Ethernet frame transport across an MPLS network, with services benefitting from the inherent reliability and resilience of the network underlay. Additional benefits include multiple topologies support, such as point-to-point, point-to-multipoint and any-to-any VPLS.

In a point-to-point set-up, we can support EPL* (Ethernet Private Line) when configured in Port-Mode as well as EVPL (Ethernet Virtual Private Line) when configured in VLAN-Mode. Arelion's collective name for these service configurations is EVPL.

*EPL service with partial L2CP transparency on certain routes. When Advanced Ethernet is ordered, L2CP transparency can be achieved by configuring the NID device in tunnelling mode.

Our on-net Ethernet EVPL and ELAN services can be delivered in as little as three weeks, including the physical connections (such as port or cross connects*) required to deploy the initial service.

Once physical connections are in place, furtherlogical services (including additional VLANs or Cloud Connect) can be provisioned in seven calendar days.

Where third party access has been requested together with the order, the lead time will vary in accordance with supplier lead times. This is generally in the range of sixty to ninety calendar days. Where delivery is impacted by way leaves or civils, it may take longer time.

*Cross Connect delivery lead time is dependent on access arrangements and LOA

Ethernet services delivered over Arelion's MPLS backbone network are inherently resilient by the very nature of the underlay network and as such are protected against network failures or fibre cuts. With multiple diverse physical routes between each Arelion PoP, we are committed to providing the best performance for our customers - four diverse routes between Singapore and Europe and four diverse routes across Atlantic demonstrate the robustness of our network.

Ethernet is one of the most affordable network technologies available - it is simple to operate, administer and maintain. Arelion serves customers in 128 countries and with more than 180 third party ENNI agreements, so we are well positioned to offer competitive pricing almost anywhere.

Additionally, our MSOP (Multiple Services on One Port) proposition allows customers to configure multiple Arelion services on a single interconnected port. This maximizes the customer value of existing interconnection points and multiple products such as EVPL, Cloud Connect or IP can then be added without the need for new interconnects.
