IGRP calculates a composite metric based on link characteristics like bandwidth, delay, load, reliability, and MTU to determine the best path. The metric is the sum of bandwidth and delay by default. Load is a 5-minute exponentially weighted average that is updated every 5 seconds. Configuring accurate delay values on links and higher bandwidth on access links can help IGRP select the fastest path through a network cloud. When redistributing routes into IGRP, the default-metric command should be used to set appropriate metric values for those routes.

Introduce to OpenVirteXsangyun han

Shared networks to support VNF high availability across OpenStack multi-regio...Joe Huang

��

Even now with all the advances to provide high level of resiliency in hardware and software components, it’s possible to have some failures. Those failures are undesirable for Enterprises and they are constantly looking for solutions which tolerate unexpected events to offer steady and unbroken services. Cloud computing solutions are not the exception. One way to achieve that is segregating the Cloud deployment in different regions. For most of enterprise applications use stateful architectures, which means that they're constantly synchronizing their status among different instances. How to provide continuously service in case of a cloud failure happens? During this presentation we will demonstrate how to architect an OpenStack multi-region solution through the existing official OpenStack projects like Neutron and Tricircle, demonstrate and compare the pros. and cons. of different tenant level L2/L3 networking topology across OpenStack clouds.

The document discusses a new approach to OpenStack automation called Group-Based Policy (GBP). GBP aims to capture an application's infrastructure needs at a higher level of abstraction, independent of the underlying implementation details. It introduces several new concepts, including groups to organize resources, traffic classifiers to define network traffic, and policy tags to apply governance rules. The goal is for applications to simply describe their requirements and dependencies rather than having to specify low-level configuration details.

Group-based Policy for NetworkingSumit Naiksatam

��

The document discusses Group-based Policy (GBP), a new Neutron sub-team that aims to simplify network configuration workflows. It outlines the team's motivation to capture user intent through policy-driven automation and declarative abstractions.

Group-based Policy For OpenStack NetworkingSumit Naiksatam

��

The document discusses Group-based Policy (GBP), a new Neutron sub-team that aims to simplify network configuration workflows. GBP introduces policy-driven abstractions that allow users to define network connectivity and security constraints through declarative policies and rules. This separates the definition of user intent from the underlying implementation and infrastructure configuration, and makes deployments more scalable, automated, and consistent. The team provides an example use case demonstrating how GBP can define connectivity policies between application tiers to meet requirements for production versus development deployments. Going forward, the team will focus on integrating GBP into OpenStack Juno and getting community feedback to further the technology.

Quantum services' chaining open stack havana design summit, portland 2013Sumit Naiksatam

��

The document discusses a proposal for allowing users to request composite network services in OpenStack by chaining together individual services. It proposes a "Services' Chain" abstraction that allows users to specify an ordered list of services with source and destination networks. The provider would publish supported "Services' Chain Templates" and handle realizing the chain by stitching together the individual services. The Quantum plugin would be enhanced to support this by having each service return attachment points and implementing the chaining logic.

Developer Experience is Dead! Long Live Developer Experience! In this keynote-style session, we’ll take a detailed, granular look at the barriers to productivity developers face today and modern approaches for removing them. 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method, we invent to deliver products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches works? DORA? SPACE? DevEx? What should we invest in and create urgency behind today so we don’t have the same discussion again in a decade?
