Improving Network Management Tools

In this post, Pete Welcher considers how to improve network management tools. The problem with these is that they are often sold to customers without any consideration for their use-cases and needs. He considers some of the path tracing tools he saw from SolarWinds at Networking Field Day as a great way to frame that information, and suggests that other network management tools would do well to adopt that methodology for other metrics.

Apstra to Demonstrate Intent-Based Data Center Network Automation with VMware vSphere Integration at VMworld

James Green first got a look at Apstra back at Networking Field Day in 2016. The company offers an intent-based networking solution based on their Apstra Operating System. They’ll be presenting at VMworld next week, and James looks at their newly announced vSphere integration. This now allows for viewing the relationships between workloads, applications, tenants, and virtual networks,with specific interfaces, CPUs, and links, to all co-exist in the same graph representation.

Apstra’s Unique Approach to Networking

Pete Welcher looks at Apstra’s intent-based networking automation solution, which he first saw at Networking Field Day last November. The company has a intention-based engine and a working fabric model, which Pete sees as a possible solution to organizations that want to automate without the hassles of scale. For Pete, it’s a solution to “fiddle-ware”. Instead of training an IT team on how to manage a series of kludgy scripts and programs, they can standardize around Apstra.

WAN Design Is Changing: What That Means for You

Based on discussions at Networking Field Day last year, Pete Welcher put together of why and how WAN design is changing. Pete sees this being driven by the needs of SaaS and cloud-based apps, which require low latency. This manifests in three design choices, centralized, decentralized, and regionalized internet access. This is a really thoughtful look on the topic, make sure to check it out!

Assuring your network will do what you think it…

Tim Miller wrote up his thoughts on what he saw from Forward Networks at Networking Field Day last year. Their solution is billed for providing network assurance, which they break down into correctness and performance. Their presentation focused on correctness, which they use sophisticated modeling to formally verify. Tim reviews the implications of their Forward Platform in terms of business intent, highlights their strong search functionality, and predication engine.

Network Verification with Veriflow

Pete Welcher saw a demonstration of Veriflow’s continuous network verification solution. In it, he saw some similarities with what he saw from Forward Networks last year at Networking Field Day. Both use formal verification of a network, with Veriflow pulling information from devices on the network and building a topograpghical model. Pete still has many of the same questions about how this would work as he did for Forward Networks, but ultimately his conclusion is “cool stuff”!
