MetroLAN

Product overview

Metro LAN is a Layer 2 service on the Metro Ethernet Network that provides intra and inter-metro connectivity and offers point-to-point, point-to-multipoint or multipoint-to-multipoint connectivity between customer sites. It is a service aimed at medium and large, corporate, global and government enterprises that have the need for a network of unmanaged, high bandwidth connections between their multiple branches. Metro LAN is positioned as a cost effective alternative to ATM with added benefits such as higher bandwidth and Bandwidth on Demand.

more about the product

Product Offering

Each customer will have a single virtual connection, or Layer 2 VPN, between all the sites differentiating their traffic from other customers' traffic. A Layer 2 VPN provides transparent connectivity between customer endpoints and enables privacy and security of customer data. Value-add Layer 3 services can be provisioned on top of the Metro LAN service.

Customers have a choice of bandwidth ranging from 4Mbit/s up to 1Gbit/s on their Metro LAN and will specify the bandwidth on a per site basis. Bandwidth on the Metro Ethernet network is scalable in small increments and additional bandwidth can be added to services relatively easy without any hardware upgrades. This feature lays the foundation for future Bandwidth on Demand (BoD) services.

Metro Ethernet is a technology that provides cost effective, high-speed connectivity in a Metropolitan Area Network (MAN) Connectivity between sites within a metropolitan area (intra-metro) as well as between metropolitan areas (inter-metro) will be allowed. The basic architecture of the Metro Ethernet network is shown in figure 1 with the inter-metro connectivity.

The Metro LAN service provides Layer 2 point-to-point, point-to-multipoint or multipoint-to-multipoint connectivity between customer sites over the Metro Ethernet network.

The Metro Ethernet network is Quality of Service (QoS) enabled and offers bandwidth Class of Service (CoS) allocation that is scalable to customers’ needs. Each CoS offers different levels of performance in terms of delay, jitter and loss. Different Classes of Service typically include Real Time (for voice applications), Business (for mission critical business applications) and General Data (best effort for Internet browsing, e-mail, etc.).

Service Level Agreements (SLA) can be offered as an addition to the Metro LAN service. Customers may rate the importance of their different sites on the Metro LAN network and depending on the impact that an outage at a site would have to their business they should select the availability package per site that best suit their needs. The availability package refers to the architecture and configuration of the CPE and access links to the Metro Ethernet network. SLA can also be offered in terms of performance with packet loss and delay specified per Class of Service.

Features & Benefits
Features
  • Telkom MetroLAN bandwidth can be added in small increments therefore you pay only for what you need.
  • Telkom MetroLAN offers high-speed connectivity between multiple sites. The connectivity can be set up between two points, point-to-multipoint or multipoint-to-multipoint.
  • When you want to add an additional site it can be added easily to the existing Metro LAN or L2 VPN – only fiber access is required from the site to the Metro Ethernet network. There is no need for point-to-point connections between multiple sites.
  • If you require permanent bandwidth increase only software changes needs to be implemented. No hardware upgrades, etc. are required.
  • Telkom MetroLAN is a cost effective alternative to ATM based offerings and offers higher bandwidth options (up to 1Gig Bit/s).
  • Telkom MetroLAN integrates easily with existing infrastructure (LAN).
  • Telkom provide and manage the Customer Premises Equipment.
Benefits
  • Convenient and cost-effective networking solution
  • The more bandwidth purchased, the greater the economies of scale
  • Fully diverse, meshed national network
  • Telkom managed Customer premises equipment (T5C module)

Terms & Conditions

The specific market for Metro Ethernet services is:

  • Corporate and Global customers
  • Key Account customers
  • Large business customers
  • ISPs
  • Mobile Operators
  • The customer is limited to 30 MAC addresses per site. (This is an arbitrary number chosen to protect the memory space on the ME network as each box needs to keep all MAC addresses in it’s tables)
  • The customers are responsible for the installation, configuration and management of any Layer 3 services on their Metro LAN.
  • The customer must be in the Metro Ethernet network footprint and have Optic Fibre to their premises . Feasibility study will be performed to determine infrastructure requirement and any Optic Fibre build will be recovered from the customer.
  • A minimum service contract of 1 year is required.
