A Segment Routing Renaissance

A Segment Routing Renaissance

The Internet was initially designed to provide best-effort connectivity over a least-cost path. Relatively few sites were connected to the Internet, and within those sites, only applications that satisfied an acceptable use policy could be connected.

 

Today, billions of businesses, households and devices are connected to the Internet. Critical applications include telemedicine, traffic control and financial transactions. Some applications (e.g., email) are tolerant of loss, latency and latency variation, while other applications (e.g., gaming) are significantly less tolerant.

In a medical emergency, every second counts. The more paramedics can do on the scene, the better it is for the patient. A more stable patient also means less need to race through traffic or for emergency handovers at the hospital, all of which impact the chance of a successful outcome.

Traffic Engineering Segment Routed Networks with NorthStar Controller

Traffic Engineering Segment Routed Networks with NorthStar Controller

Designing a network that provides optimal SLAs for its applications – bandwidth & latency guarantees, uptime and responsiveness - while reducing costs is a classic networking challenge. Historically, network planners have used sophisticated tools such as WANDL’s IP/MPLS View for capacity and scenario planning. Similarly, leading routing vendors have delivered real time end-to-end traffic engineering with built in CSPF (Constrained Shortest Path First) algorithms and RSVP-TE. These technologies have driven the growth of Internet and cloud applications by ensuring that cloud applications achieve desired network SLAs.

 

However, as cloud traffic continues to surge and new cloud services continue to go viral, network architectures must become simpler and more modular. New network architectures must allow more service customization and agility, while utilizing more cost effective routers/switches to transport ever increasing traffic economically. Most critically, network architectures must simplify operations.

 

Segment Routing (IETF name: SPRING) delivers network simplification by eliminating MPLS signaling protocols such as LDP and RSVP. It eliminates the hop-by-hop LSP path setup paradigm and allows the head-end router (or an application) to define the entire path for the application traffic by encoding path information in the packet itself. In this new SR paradigm, since the network contains no traffic engineering (TE) information, a Segment Routing (SR) controller is a must in order to ensure real time, end-to-end application level TE and SLA guarantees.

Bringing Together AWS and Vodafone SD-WAN

Bringing Together AWS and Vodafone SD-WAN

At AWS re:Invent 2018, Vodafone and Juniper Networks announced the availability of virtual end-points for Vodafone SD-WAN within AWS. The solution uses the same underlying infrastructure as the other parts of the Vodafone SD-WAN service. However, instead of using a physical device at the customer site the solution deploys a secure SD-WAN endpoint (Juniper Networks vSRX Integrated Virtual Firewall) in AWS that is then connected back to the Vodafone global network.
