This talk will give a general Introduction to the ONOS multi layered architecture and it's distributed system platform. It will provide details around the protocol-agnostic distributed core, replication of data and state maintenance. Il will also cover the notions of an ONOS cluster and how it works.
Legacy network transition to SDN network need a gradual transition. So PCE as Central Controller(PCECC) help to move control plane of MPLS network and provide programmability and agility to the network
This talk will outline how you can interact with ONOS both from a device perspective ins the SouthBound(SB) and from an user/application perspective in the NorthBound(NB).
The talk will cover the different interfaces and primitives offered from the protocol agnostic NorthBound, from Intents to FlowObjectives and will also discuss ONOS APIs.
The talk will also describe how ONOS deals with the multiple protocols on the SB and treats the different device configurations in order to make the application network centric and free it from dealing with device specifics.
Using YANG, applications are abstracted about the external protocol interaction. Application are requited to model the NBI interface in YANG and implement the business logic. YANG framework, automates the external world interaction.
Driver / provider to register the device schema to YANG management system and interact with device (SBI) using POJO generated from YANG files.
This talk will outline the current ONOS deployments across the world in research networks and universities. It ill describe the hardware requirements and the software that runs on top of it to have seamless integration with existing non-SDN networks. It will cover the basics fo how you can start deploying on your testbed. A topic will also be SDN-IP a widley deployed application that enables seemles integration between SDN OpenFlow based networks and traditional IP networks.
The objective of this work is to implement an SDN-WAN solution to optimize the allocation of paths connecting geo-distributed data centers.
The SDN-WAN architecture adopted in this project leverages PCEP and BGP-LS protocols provided by ONOS.
To implement this architecture, we make of use ONOS framework and IOS-XR v Cisco routers. Then, we extend PCE algorithm to enhance the quality of selected paths. The results demonstrate that our approach improves QoS applications while ensuring load balancing of the network infrastructure.
This talk will outline the details behind building an ONOS application. The talk will be divided into two main parts:
- a technical presentation about what is an ONOS application and how it works in the clusters environment
- a hands on live demo of building a sample ONOS application from scratch to running code.
Mobility is one of the most ubiquitous technology of today's modern networks. On boarding end to end mobility services is a complex process. Doing so in DEVOPS model intensifies the process and resource dynamics. Agile services creation, onboarding, and full lifecycle management of these mobility services will be critical for commercial success and rapid industry adoption. Virtualized and disaggregated mobility service creation via northbound APIs, service chaining, and orchestration requires an end to end view from DevOps programmable models to service deployment and mechanisms for rapid innovation with new incremental service creation. This session will explore some of the challenges and successes with e2e integration with ONOS architecture in this realm as the industry collectively moves forward in this new and exciting space.
Smart SFC is an ONOS based application which aims to bring smartness to the current SFC solution by Reducing operators TCO by providing efficient resource utilization, increasing customer satisfaction by enhancing reliability, satisfying customer SLAs by real time resource monitoring and enabling quick provisioning by providing a smart intent GUI framework.
Smart SFC attractions
-------------------------------
1. Intent(GUI) based chain provisioning based on constraints(CPU, Memory, Jitter, Delay)
2. Explicit chain creation.
3. Chain SLA assurance is guaranteed by real time monitoring SF resources
4. Support SFC data path tracing.
5. Support Calendering.
6. SF resource management.
7. Dynamic SF addition/deletion based on need basis
8. SFC Protection and load balancing
