By selecting the service levels and characteristics that best suit your application environment, you can achieve optimal performance and get the best value for money from your network services. How it works MetroEthernet supports a wide range of service options. Choose from the following 1. Service Availability five options for service availability depending on criticality of the service. 2. Service configuration choose between EPL, EVPL, EP-LAN or EVP-LAN. 3. Bandwidth different levels, as well as Committed Information Rate or Excess Information Rate. 4. Service Frame Format tagged (single tag, double tag) or untagged frames to manage your data traffic. Business benefits Optimum performance Customising your service ensures your particular business requirements can be met in the most efficient manner. Flexibility You get services that closely match your requirements with multiple configuration and service options to choose from. So you can manage your costs and performance effectively. Ease and simplicity Clear and easy to understand options ensure you get a connectivity solution that meets your requirements. Your MetroEthernet service will be delivered with your specific combination of service features. This service is internationally certified for performance and reliability by the Metro Ethernet Forum.

2 Service availability options You have the flexibility to choose different levels of service availability according to the criticality of your service. The higher availability options provide added redundancy within the VectorFibre network so that your services are still running even if unlikely events, such as a disruption to fibre or equipment fault should occur. Demarcation Option 1 The service is delivered over a single building entry with two fibres (or fibre pairs) in the same cable via a single building entry terminating on a single. This option protects the service against a fibre fault on an individual fibre (or fibre pair). The service is provided from a single core network node. Demarcation Option 2 The service is delivered on two diverse fibre (or fibre pairs) using two building entries with cable and duct diversity terminating on a single. This option protects the service against a fibre faults or cable fault. The service is provided from a single core network node. Option 3 The service is delivered on two diverse fibres (or fibre pairs) using two building entries with cable and duct diversity terminating on two independent s. This option includes two s and may enable you to share bandwidth between the s. This option protects the service against a failure of the, or a fibre fault or cable fault. This option includes two s. Option 4 The service is delivered on two diverse fibres (or fibre pairs) each connected to independent core nodes providing station diversity using two building entries with cable and duct diversity terminating on two independent s. This option includes two s. This option protects the service against a fibre or cable fault, fault of the or a fault of a core network node. In this case, the failover of the service is controlled entirely by you. Option 5 The service is delivered on two diverse fibres (or fibre pairs) each connected to independent core nodes providing station diversity using two building entries with cable and duct diversity terminating on two independent s. In addition, the service between each core node and the end customer site is delivered on two diverse fibre (or fibre pairs). This option includes two s. This option reduces the risk of multiple fault events causing a service outage.

Geographic diversity the additional link is carried over a duct that is geographically diverse. Station diversity the additional link is connected through to a different core network node.

4 Service configuration options You can choose between three different network configurations. EPL Ethernet Private Line (EPL) What it does Provides point-to-point connectivity with transparent Ethernet frame forwarding and committed rate bandwidth. Point-to-Point EVC Linking local networks at two sites. Frame-loss and jitter sensitive applications such as Video and Voice. Low-latency applications such as financial services. Continuous high-speed connection to a remote server, application host or corporate data centre. Real-time data mirroring with remote back-up service. 100% Committed Information Rate (CIR) connection, meaning the bandwidth you specify is reserved exclusively for your own use. Fully transparent connectivity. EVPL Point-to-Point EVC 1 Ethernet Virtual Private Line (EVPL) What it does Provides point-to-point connectivity with the ability to aggregate multiple services onto a single. Service Multiplexed Point-to-Point EVC 2 High-speed customer connections for ISPs and other service providers. Giving key suppliers and customers secure access to your network. Distribution of centrally stored data or applications to remote sites. Remote backup across multiple, mirrored servers for security and rapid disaster recovery. Connect to multiple customers via a single to minimise cost and management complexity.

5 EP-LAN Ethernet Private - LAN (EP-LAN) What it does Enables interconnection between multiple sites so all sites appear on the same Local Area Network (LAN) and have equivalent performance and access to resources with transparent Ethernet frame forwarding. Multipoint-to-Multipoint EVC Creating a wide area network for organisations that require high performance and transparency, including intra-company voice and data communications. Sites can be quickly and easily added to an EP-LAN, without reconfiguring existing sites. Fully transparent connectivity. Seamlessly share data, applications or services across the enterprise or with business partners. EVP-LAN Multipoint-to-Multipoint EVC Ethernet Virtual Private - LAN (EVP-LAN) What it does Enables interconnection between multiple sites with the ability to aggregate services onto one or more s. Service Multiplexed Point-to-Point EVC Creating a wide area network for organisations that often work together, including intra-company voice and data communications. Sites can be quickly and easily added to an Ethernet LAN, without the need to reconfigure existing sites, to minimising cost and management complexity by aggregating services on to one or more s.

6 Bandwidth profile options You can choose the bandwidth profile that best suits your application environment either Committed Information Rate or Excess Information Rate. Committed information rate (CIR) Excess information rate (EIR) What it does Configurations The contracted bandwidth is guaranteed, reserved for your use and is available at all times regardless of traffic volume. Running critical applications that require consistent bandwidth throughput, e.g. Voice and video communications Remote server access for applications, Connectivity replacing current leased lines or SDH circuits. Bandwidth at all times so that your critical applications can rely on the connectivity. Consistent performance from the WAN connectivity. Ethernet Private Line (EPL) Ethernet Virtual Private Line (EVPL) Ethernet Private LAN (EP-LAN) Ethernet Virtual Private LAN (EVP-LAN) The bandwidth may be available depending on the volume of traffic over the network at any given time. Running non-critical applications or applications that do not require consistent data throughput, e.g. Internet data backup and other applications that are not strictly time bound non-chatty applications that can accommodate inconsistencies in available bandwidth applications with a high degree of variation in usage with very high peaks. Good quality connectivity at a cost effective price point for running non-critical applications. Take advantage of the lower performance need of certain applications.

7 Service frame format options You can choose to use tagged or untagged Ethernet frames at any. By default, MetroEthernet services are configured to support untagged frames. Choosing tagged frames allows you to divide your traffic, secure data streams over the same Ethernet Virtual Connection (EVC). MetroEthernet services support both single tag (IEEE 802.1Q) and double tag (IEEE 802.1AD). Tagged service frames are recommended for: Service providers aggregating services from different end-customers onto a single. Using a single EVC to carry traffic such as backhaul traffic, where you need to identify the origin of the traffic. Creating a virtual network infrastructure for providing services at higher layers Untagged service frames are recommended for: When you want to keep the configuration simple, e.g, when you are connecting branches to a head office it enables you to use an untagged frame for the branches. This reduces the cost of equipment and management at the branches. When the service frame format is tagged, the can accept untagged or tagged frames. In addition, you can manage your own tags using double tag (IEEE 802.1AD). This provides flexibility for you to manage your own tags. Alternatively you can request for additional VLANs to be bundled to your EVC (subject to an additional charge). You can specify the service frame format for each. A typical scenario is depicted below with three s where s A, B, C are only capable of handling untagged Ethernet frames whereas D can accept tagged frames.
