Arrcus Introduces Scalable, Automated, Multi-Tenant EVPN Fabrics

ArcOS® Lowers OpEx in 5G, Data Center, and Edge Deployments through Operational Simplicity, Greater Agility, and Carrier-Class Reliability

SAN JOSE, Calif., March 26, 2019 (GLOBE NEWSWIRE) -- Arrcus, a leading provider of the software that powers network infrastructure and its transformation for the interconnected world, announced the ArcOS® Ethernet Virtual Private Network (EVPN) solution for building programmable, multi-tenant routing fabrics based on BGP EVPN/VXLAN on multiple 10GbE/25GbE/100GbE/400GbE switching platforms.

This solution enables service providers and enterprises to use advanced open, microservices-based networking software to build massively scalable multi-tenant Clos fabrics. Built from first principles, the ArcOS BGP EVPN/VXLAN fabric solution provides key business benefits including:

  • Operational simplicity that accelerates the time-to-delivery of applications and services
  • Scalable multi-tenancy and network resiliency
  • 60% lower east-west application latency with massive fan-out scale fabric
  • Open integration across multiple hardware vendors for supply base diversification and deployment agility

As with the recent 400G announcement supporting Broadcom’s StrataXGS® Tomahawk® 3 silicon, Arrcus continues to deliver innovative solutions to meet the demands of modern network infrastructure. With the BGP EVPN/VXLAN solution, Arrcus enables new use cases including:

  • BGP EVPN Clos with high-radix, high-density 100G Tomahawk 3-based switches and Trident 3-based switches for spine-leaf network architectures
  • Inter-PoD fabric stretch with BGP EVPN
  • Multi-PoD fabrics with L3 BGP EVPN

“Bandwidth-intensive network applications are pushing the need for higher-density data center fabrics with low latency and high performance. Delivering operational simplicity at scale for network operators of these fabrics has been a key goal for us at Arrcus,” said Keyur Patel, co-founder and CTO, Arrcus. “The ArcOS EVPN/VXLAN solution in combination with standards-based BGP LSVR helps address the critical need in the market for programmable and highly scalable multi-tenant data center fabrics.”

The architectural advancements supported by the ArcOS BGP EVPN/VXLAN solution include:

  • Innovative, standards-based IGP fabric option with BGP-based Link State Vector Routing (LSVR) in addition to the traditional IGP options
  • Integrated Routing and Bridging (IRB), IPv4, IPv6 BGP EVPN with automated peer discovery and per-process restartability for resiliency
  • Rapid, automated host discovery and support for workload mobility
  • Simplified provisioning and deterministic convergence with Link State Over Ethernet (LSOE)
  • EVPN over LSVR that brings simplified operations with a single protocol to manage
  • Per-tenant fabric visibility with streaming telemetry
  • Seamless standards-based API integration into popular provisioning frameworks such as Ansible/Puppet/Chef/SaltStack or popular centralized controllers

“At LinkedIn, we are working on a self-defined networking concept that does not require any configuration nor any static arrangements. Our self-defined network elements discover and define their role and function in an automatic and self-driven fashion,” said Shawn Zandi, Director of Network Engineering, LinkedIn. “Link State Over Ethernet (LSOE) will enable networks to achieve this goal. It is exciting to see Arrcus introduce this capability in ArcOS®.”

In this era of distributed data centers for 5G and edge computing environments, the ArcOS BGP-EVPN/VXLAN solution is optimized to support the deployment of massively scalable, highly programmable data center fabrics. ArcOS also offers differentiated streaming telemetry capabilities and its standards-based OpenConfig APIs allow seamless integration into existing orchestration or telemetry systems.

Industry Quotes

Ecosystem Partners

Avinash Parwaney, Vice President Engineering, Lumina Networks:
“In the multi-vendor environments of 5G, the support for standards-based control protocols of ArcOS®, such as BGP EVPN, when paired with the centralized management from Lumina's SDN Controller will drastically reduce complexity of Clos fabric configuration and management. With support of streaming telemetry to enable closed-loop automation, this solution provides a flexible foundation for 5G service deployments.”

Standards Bodies

Victor Kuarsingh, LSVR Working Group Co-Chair:
“I am happy to see BGP-based LSVR making its way into software implementations. The use of BGP-based LSVR as a hybrid underlay protocol can help operators deploy robust and dynamic data center fabrics while maintaining the operational simplicity desired by many in large scale deployments.”

Gunter Van de Velde, LSVR Working Group Co-Chair:
The routing needs of a data center are different than that of the WAN. The era of SDN-based control combined with the ongoing shift towards hyperscale IoT and cloud-based services is driving the need for a hybrid routing protocol in data centers. It is exciting to see Arrcus drive innovation in the data center underlay by delivering the support for BGP-based LSVR.”


The BGP EVPN/VXLAN support on ArcOS® will be generally available in July 2019.
