The BGP swiss army knife of networking
Snabb (formerly "Snabb Switch") is a simple and fast packet networking toolkit.
We are also a grassroots community of programmers and network engineers who help each other to build and deploy new network elements. We care about practical applications and finding simpler ways to do things.
VXLAN is an overlay network to encapsulate Ethernet traffic over an existing (highly available and scalable, possibly the Internet) IP network while accomodating a very large number of tenants. It is defined in RFC 7348. For an uncut introduction on its use with Linux, have a look at my “VXLAN & Linux” post.
VXLAN is an overlay network to carry Ethernet traffic over an existing (highly available and scalable) IP network while accommodating a very large number of tenants. It is defined in RFC 7348.
Starting from Linux 3.12, the VXLAN implementation is quite complete as both multicast and unicast are supported as well as IPv6 and IPv4. Let’s explore the various methods to configure it.
The installation of the Openvswitch on Ubuntu brings an automatic integration into the boot sequence. When Ubuntu is booted, the Openvswitch is also started. Any bridge or port, which has been defined in previous sessions, is restored.
BUT: No L3 interfaces are set up, junk interfaces, which have been defined in previous sessions, are restored.
Open Networking Solution are based on open standard, bare-metal hardware with a choice of independent open software for NOS (Network Operating Systems), SDN, virtualization, and cloud orchestration. For years, hyper-scale data center operators have been enjoying the benefits of Open Networking Solution: reduced network equipment expenses, automated and accelerated provisioning of network capacity and services, greater control over the development of enhanced network services, flexibility to work with best-in-class suppliers, and reduced operating expenses.
These Open Networking benefits are now available for many more networking use cases. Public and private cloud data centers of all sizes are being deployed with network fabric built from open leaf and spine switches. Edgecore Networks offers choices of hardware to meet open network deployment, from 1G, 10G, 25G and 40G, to 100G.
The Guide to IP Layer Network Administration with Linux was conceived as a project to document and provide examples for the use of Linux-specific IP networking tools.
The book includes coverage of the following topics: network address translation (NAT), address resolution protocol (ARP), routing, and masquerading. There is a nascent section on bridging, although the focus of the documentation is the use of layer 3 Linux technologies.
Modeled after documents hosted at TLDP, this effort is a contribution to the Linux community undertaken of free will and in free time. I intend to release the completed guide to TLDP for inclusion in the documentation repository.

The eternal loathing between Storage and Networking professionals has manifested into a podcast when I am joined by well known storage bloggers to debate our dysfunctional family relationship.
Thanks to Martin Glassborow from Storagebod and Chris Evans from Architecting IT for taking the time to talk about networking and storage.
