Ethernet Access Devices

Ethernet Access devices (EADs) are commonly used in telecom for delivering business services and mobile backhaul. These devices offer high bandwidth and powerful Carrier Ethernet performance monitoring capabilities to assure quality of service. According to IHS research, the market for EDAs is quite mature, yet constantly growing – 8% in 2017. With the need to reduce costs, accelerate service speeds, and quickly introduce new services, including security, operators are finding it challenging to stay competitive while using traditional ASIC-based EADs. Moreover, with the transition to SDN/NFV, many operators consider the virtualization of CPE for business as a highly attractive business case.

With these rapidly evolving EAD market changes, Ethernity offers OEMs and system integrators unique FPGA-based EADs, all using small FPGA die-size for attractive pricing, and complete networking IP and data acceleration firmware. Our low-cost EAD solutions allow full remote re-programmability to account for any new customer needs. Ethernity offers solutions that leverage both our technology and our experience for OEMs designing their own EADs, and ready-made fully programmable EADs for system integrators. Our programmable EADs also include a PCIe Gen3 port for connecting to external commercial-off-the-shelf (COTS) servers and for accelerating applications in universal CPE (uCPE) mode.

Ethernity’s MEF CE.2 compliant ENET3850Z and ENET4200Z switch-router flow processors provide a cost-effective engine for Carrier Ethernet access functionality and, as such, perform advanced header parsing, pattern matching, bit manipulation, classification, packet modification, data movement, inverse multiplexing, EFM bonding, and hierarchical traffic management.

The universal interworking functionality in ENET3850Z and ENET4200Z supports packet editing, which provides the ability to receive packets in any format and to change a protocol per flow to any other protocol, supporting Ethernet II, SNAP, Q-in-Q, MAC-in-MAC, MPLS, PPP, PPPoE, L2TP, or any other type of L2 protocol.

Service Demarcation

Carrier Ethernet services demarcation is necessary for understanding and controlling the contribution of each network segment to the overall service degradation, allowing administrators to quickly isolate problems and take proactive measures to solve them.

Clear demarcation enables SLA monitoring, service performance reporting, and avoids billing disputes between the user and service provider in retail scenarios, or between different providers in wholesale scenarios.

Ethernity’s patented programmable ENET Flow Processor, implemented on a Xilinx Zynq FPGA, is ideal as a hardware platform for the SLA Prob functionality, and is a good match for both fixed and mobile networks.

Ethernity offers ENET3850Z, a low-cost switch-router flow processor, specially optimized for Ethernet demarcation NIDs, and ENET4840Z-OAM, a high performance, configurable flow processor, targeted for improving SLA Prob functionality over the CE network. This OAM co-processor can be used as a complementary SLA solution for high capacity switch-routing products. It allows for SLA feature customization and has an integrated programmable OAM packet generator and analyzer, supporting 802.1ad, 802.1ah, 802.1ag, Y.1731, and BFD.
