Extensions to the Access Control Lists (ACLs) YANG Model

Individual IETF Internet-Draft - October 2022
NO LONGER ACTIVE DRAFT - RFC 8519 defines a YANG data model for Access Control Lists (ACLs). This document discusses a set of extensions that fix many of the limitations of the ACL model as initially defined in RFC 8519.

A YANG Data Model for Intermediate System to intermediate System (ISIS) Topology

Individual IETF Internet-Draft - October 2022
NO LONGER ACTIVE DRAFT - This document defines a YANG data model for representing an abstract view of the provider network topology that contains Intermediate System to intermediate System (ISIS) information. This document augments the 'ietf-network' data model by adding ISIS concepts.

Instantiation of IETF Network Slices in Service Providers Networks

Individual IETF Internet-Draft - March 2023
Network Slicing (NS) is an integral part of Service Provider networks. The IETF has produced several YANG data models to support the Software-Defined Networking and network slice architecture and YANG- based service models for network slice (NS) instantiation. This document describes the r

A YANG Model for Network and VPN Service Performance Monitoring

IETF RFC 9375 - April 2023
The data model for network topologies defined in RFC 8345 introduces vertical layering relationships between networks that can be augmented to cover network and service topologies.

A YANG Network Data Model for Layer 2 VPNs

IETF RFC 9291- September 2022
This document defines an L2VPN Network Model (L2NM) that can be used to manage the provisioning of Layer 2 Virtual Private Network (L2VPN) services within a network (e.g., a service provider network).

A Layer 3 VPN Network YANG Model

IETF RFC 9182 - February 2022
As a complement to the Layer 3 Virtual Private Network Service Model (L3SM), which is used for communication between customers and service providers, this document defines an L3VPN Network Model (L3NM) that can be used for the provisioning of Layer 3 Virtual Private Network (L3VPN) services withi

A Common YANG Data Model for Layer 2 and Layer 3 VPNs

IETF RFC 9181 - February 2022
This document defines a common YANG module that is meant to be reused by various VPN-related modules such as Layer 3 VPN and Layer 2 VPN network models.

Demo Paper: "Slice Grouping for Transport Network Slices Using Hierarchical Multi-domain SDN Controllers"

2023 Optical Fiber Communications Conference and Exhibition (OFC2023)
This demonstration showcases how TeraFlowSDN provides support for hierarchical control of multiple heterogeneous SDN domains (through IP, microwave and optical technologies). Different transport slices are offered with multiple SLAs and grouped to optimize resources.

Demonstration of Zero-touch Device and L3-VPN Service Management using the TeraFlow Cloud-native SDN Controller

2022 Optical Fiber Communications Conference and Exhibition (OFC2022)
We demonstrate zero-touch device bootstrapping, monitoring, and L3-VPN service management using the novel TeraFlow OS SDN controller prototype.

Experimental Demonstration of Transport Network Slicing with SLA Using the TeraFlowSDN Controller

2022 European Conference on Optical Communication (ECOC2022)
This demo presents the TeraFlowSDN controller as a solution to provide dedicated transport network slices with SLAs. To this end, the demo details how the interface between an NFV orchestrator and the SDN controller can provide transport network slices using protected disjoint paths.

Demo paper: “Operationalizing partially disaggregated optical networks: An open standards-driven multi-vendor demonstration”

2021 Optical Fiber Communications Conference and Exhibition (OFC2021)
We present and demonstrate service provisioning in partially disaggregated multi-vendor network automation scenarios with online physical impairment validation.

Advances in SDN control for Beyond 100G disaggregated optical networks

2021 European Conference on Optical Communication (ECOC2021)
This tutorial considers the evolution of SDN control for optical transport networks in disaggregated scenarios, focusing on its requirements and challenges when applied to "beyond 100G" networks - term that jointly refers to the use of coherent technology, data rates beyond 100G and the evolution

Demo paper: Scalable and Resilient Network Traffic Engineering Using Erlang-based Path Computation Element

2021 - VII IEEE Conference on Network Function Virtualization and Software Defined Networks (IEEE NFV-SDN 2021)
Scalability and resiliency are two significant requirements for upcoming beyond 5G networks. As network resource usage is expected to increase, scalability of the control plane handling the required amount of network resources is also necessary.

Field Trial of Programmable L3 VPN Service Deployment Using SDN-Based Multi-domain Service Provisioning over IP/Optical Networks

2021 - IEEE Network, Vol. 35, Issue 6, November/December 2021
Network operators cannot change their footprint to upgrade the entire network to support SDN from scratch. Hence, network operators adapted the original SDN concept into a hybrid SDN approach to have a pragmatic, evolutionary, and economically viable solution.
