vBRAS

Broadband remote access servers (BRAS), also referred as Broadband Network Gateways (BNG), are specialized hardware devices at the edge of a service provider’s core network that route traffic to and from subscribers. BRAS serve as the main gateway element and must support massive throughput and be scalable enough to handle the significant growth in data usage that is expected from ultrabroadband services. Traditional BRAS has fixed control plane and data plane capacity, which eliminates the flexibility to independently scale each of these elements to match actual network conditions.

A virtual BRAS solution, however, delivers a separate, software-based control plane, as well as a data plane that can scale independently and benefits from hardware acceleration.

Ethernity offers an effective vBRAS solution that enables reduced power and space requirements and frees the CPU to run additional user sessions, resulting in lower latency and more deterministic results. In turn, this reduces total cost of ownership (TCO) by enabling accelerated performance.

Ethernity’s FPGA-based ACE-NIC smart network adaptors provide optimized data transfer using patented ENET Flow Processor technology. They offload resource-consuming virtual functions to FPGAs. This hardware acceleration helps to optimize the following tasks:

  • Providing Layer 2 connectivity through either transparent bridging or PPPoE.
  • Enforcing quality of service (QoS) policies, service level agreements (SLAs), and billing.
  • Providing Layer 3 connectivity and routing IP traffic through a backbone network to the internet.

The programmable nature of the ENET FPGA-based platform provides a truly open solution with complete serviceability to satisfy an operator’s specific network application scenarios.
