Overture 65vSE


The Overture 65vSE is the industry’s first open Carrier Ethernet platform for hosting virtual network functions at the service edge.

The 65 Virtual Service Edge (vSE) is the newest member of the Overture 65 series. It allows communication service providers (CSPs) to instantly deploy on-demand virtualized network functions (VNF) at the customer premise to simplify operations and unleash new service innovation. By decoupling hardware from software, the Overture 65vSE enables a completely programmable network that dramatically accelerates service creation,  activation and assurance.

Open Platform for Any Managed Service

The Overture 65vSE combines Carrier Ethernet access with the benefits of virtualization, openness and software-defined services. The result is one platform for both services and network access.

As an open, general-purpose compute platform, the Overture 65vSE is specifically designed for managed services delivered on the customer premise. It can host multiple combinations of software-based virtual network functions (VNFs) that may be required for a given service.

With modular interfaces and a 100% programmable architecture, the 65vSE allows the CSP to deliver a complete managed service portfolio using a single platform instead of the multiple appliances currently required.



Radically Improved Service Velocity
The Overture 65vSE increases service velocity by combining Carrier Ethernet access and virtualization to introduce new service offerings via software.

CSPs can rapidly move from service definition to deployment, allowing them to react to new market opportunities and proactively test the market with innovative new service ideas. With the 65vSE in place at the customer premise, new services can be installed or upgraded remotely in minutes with no shipping charges or on-site technician.

Truly Open
The Overture 65vSE decouples hardware from the networking software in a truly open system so that the CSP can leverage best-of-breed suppliers for the VNFs. A carrier-grade platform based on Intel x86 micro-server technology, the Overture 65vSE is able to take advantage of many off-the-shelf software components and hardware expansion via standard PCIe, SATA and USB interfaces. The 65vSE comes pre-loaded with Overture’s state of the art Ethernet Access Device (EAD) software and can host additional VNFs.

Ubiquitous Reach with Wireline and Wireless Connectivity
The Overture 65vSE supports both wireline and wireless connections to the WAN, allowing access to all end customer locations.  

It comes with 1GigE optical network interfaces built into the base platform. Using optional interface modules, the 65vSE can connect to the CSP network via bonded copper, TDM and LTE interfaces. Interface types may be combined to support protection switching between wireline and wireless media for exceptional resiliency.

Flexible Carrier Ethernet-Based Compute Platform
The Overture 65vSE combines Carrier Ethernet access and a flexible virtualization platform to deliver dynamic new services with agility and speed never before possible. Virtual network functions may be turned up, turned down, added and removed dynamically so that compute and storage resources are used only when needed. This opens the door for a new, on-demand service model for applications such as temporary video caching, tele-presence or test generation. The functions are enabled only while the service is being used, and then freed up afterwards for use by another service.

Intergral Part of Ensemble OSA
The 65vSE is part of Overture’s Ensemble Open Service Architecture(OSA), the industry’s first open architecture for software-defined services at the metro service edge. By introducing automation, open APIs and orchestration into the metro service edge, Ensemble OSA radically accelerates the innovation cycle and enables a new generation of on-demand, application-aware services.

As with other components of Ensemble OSA, the Overture 65vSE can be deployed independently or in conjunction with the Ensemble Service Orchestrator (ESO) and/ or Ensemble Network Controller (ENC). ESO, for example, can be used when the CSP wishes to coordinate the configuration and management of Carrier Ethernet WAN connections and virtual resources in the Overture 65vSE and virtual resources in a centralized location such as a datacenter or central office.

Optimized Placement of Virtual Network Function
There are times when VNFs are well suited for deployment in a central location like a datacenter, central office or point-of-presence. Historically, network functions virtualization has been limited to this centralized deployment model. There are increasing times when the security or latency requirements of certain VNFs dictate optimal placement is on the customer premise, or service edge. Finally, for some sophisticated services, the network functions may need to be chained together across multiple host locations for optimal performance or efficiency.

The Overture 65vSE enables a hybrid NFV model whereby the virtual network functions are placed in the optimal location – the service edge, a central location, or both.

When to Host Virtual Network Functions at the Service Edge
Motivation Description
Performance Distributing functions can increase scale and processing power. Some functions (e.g. URL filtering) affected by bandwidth and delay may impact the customer experience.
Feasbility Some virtual functions, such as WAN optimization, service testing, end-to-end security and QoE monitoring may be more appropriate at the service edge.
Cost Locating certain virtual functions at the service edge may save access network bandwidth requirements and eliminate redundancy requirements, thereby reducing costs.
Security Due to policy or data sensitivity, certain security functions are more effective if located at the service edge.

When to Host Virtual Network Functions at the Datacenter, CO or POP

Motivation Description
Performance An aggregation point one hop from the edge may reduce delay and packet variation for some functions.
Feasbility Certain functions which monitor or condition traffic toward the network should be placed where traffic is aggregated. Functions which filter or condition downstream traffic to protect access links are best located at an aggregation point.
Cost Locating functions at an aggregation point allows for resource pool sharing and the associated economies of scale. Hosting functions centrally may reduce metro/core traffic backhaul requirements.
