ETX-2i from RAD
IP & Carrier Ethernet Demarcation with D-NFV
Feature-rich demarcation and aggregation suite, offering a complete Service Assured Access (SAA) solution, Line rate Layer-3 services, and vCPE applications, including distributed network functions virtualization (D-NFV) for rapid rollout of new services and network capabilities
The ETX-2i IP & Carrier Ethernet Demarcation with D-NFV device is the main component of RAD’s Service Assured Access solution, providing:
ETX-2i is offered in a variety of product options: ETX-2i, ETX-2i-B, and ETX-2i-10G. ETX-2i is a next-generation hybrid L2 and L3 demarcation device. The RAD ETX-2i-B branch office device is an optimized access box adapted to the requirements of nextgeneration vCPE networks. The ETX-2i-10G device is an ETX-2i version supporting 10GbE ports. Table 1 provides further information on the capabilities offered by each ETX-2i device.
MARKET SEGMENTS AND APPLICATIONS FOR RAD ETX-2i
ETX-2i is ideal for carriers, service providers, wholesale providers, and mobile operators seeking to offer unified SLA-based Ethernet business services, such as E-Line, E-LAN, E-Tree, and E-Access services, as well as L3 VPNs and value-added services using virtualization at the customer edge.
ETX-2i NETWORK TOPOLOGIES AND INTEROPERABILITY
ETX-2i supports several network topologies such as linear, daisy chain, and self-healing rings (G.8032v2), working with ETX-5 or third-party Ethernet devices.
VCPE with RAD ETX-2i
ETX-2i leverages Network Functions Virtualization (NFV), allowing carriers to provide a vCPE solution in various models, including Centralized and Decentralized architectures. This solution reduces CAPX and OPEX by eliminating the physical appliance required for hosting network functions.
The D-NFV options allow for seamless insertion of i7 and ATOM (Rangeley) based x86 cards as an optional module. The D-NFV module hosts virtual machines providing virtual network functions (VFs) or value-added service capabilities. This enables service providers to quickly and easily provide new services and implement new network capabilities, with the benefit of function localization at the customer premises.
VCPE-OS SUPPORT FOR D-NFV ON RAD ETX-2i
The ETX-2i and ETX-2i-B D-NFV options are provided with RAD’s vCPE-OS software platform. ETX-2i is a Linux based, carrier-class operating system for vCPE applications, with open management interfaces. vCPE-OS runs on any white box server and can be preloaded in RAD’s virtual CPE (vCPE) platforms. It combines powerful networking capabilities with virtualization for hosting SDWAN and any other value-added virtual network function (VNF) applications from multiple vendors. For more information on vCPE-OS, please refer to the vCPE-OS datasheet.
RAD ETX-2i CARRIER ETHERNET 2.0
ETX-2i incorporates a complete set of CE 2.0certified Ethernet service tools that allow the service provider to distinguish between high and low-priority traffic, and optimize TCP sessions.
ETX-2i provides MEF 10.3 color aware and unaware policers, delivering high-scale multi-CoS services with hierarchical Quality of Service (HQoS).
It supports advanced scheduling, WRED per CoS, shaping per EVC and per port, with flexible classification rules and access lists.
ETX-2i delivers E-Line (EVL, EVPL), E-LAN (EPLAN, EVPLAN), E-Tree (EP-TREE, EVP-TREE), and E-Access services.
Layer-2 ETX-2i Control Processing
ETX-2i can be configured to forward or discard Layer-2 control frames (including other vendors’ L2CP frames).
ETX-2i supports DHCP Snooping with Option 82 for protection of DHCP transactions.
With MLDv2 snooping, multicast data is selectively forwarded only to a list of self learned ports (per multicast group membership), instead of being flooded to all ports in a VLAN.
RAD ETX-2i models with enabled routing offer Virtual Routing and Forwarding (VRF) instances, allowing service providers to deploy L2 and L3 VPNs. The forwarding engine capability ranges from 1 to 8 Gbps, allowing Carrier Ethernet and IP services to be offered in a single device providing high-capacity performance monitoring, network function virtualization (NFV), and more.
ETHERNET OVER IP/GRE ETX-2i
RAD ETX-2i models with enabled routing offer Ethernet over IP/GRE tunneling (up to 32 IPv4 or IPv6 tunnels), allowing service providers to extend Layer-2 services to out of footprint sites over IP transport.
TDM PSEUDOWIRE ETX-2i
ETX-2i from RAD provides pseudowire (PW) services via a smart SFP (MiTOP). The PWs can be encapsulated using CESoPSN per IETF RFC 5086 or SAToP per IETF RFC 4553.
ETX-2i transports Ethernet over PDH infrastructure via the following NG-PDH technologies:
Common models include:
