HP Networking announces a Whitebox Ethernet product line that runs Cumulus Linux.

In delivering this brite box solution, HP is differentiated from original design manufacturers and other competitive offerings through its ability to de-risk supply chain concerns, provide global presence in over 160 countries and deliver a wide range of high value support and consulting services. The new product line is designed to enable a more agile IT infrastructure and improve time-to-market for IT services. Another customer benefit is lower total cost of ownership due to using standards based hardware and streamlined software that reduce acquisition and operating costs by up to 68%.

Has Arista finally realised that SDN is a thing ? It might be so.

SDN (Software Defined Networking) is finally becoming clearer. It is not Still Don t Know nor is it a specific overlay controller. Simply put, it is an open and programmable way to build networks for customers looking at utilizing hybrid combinations of public and private cloud access.

We are witnessing a shift from multi-tier oversubscribed legacy enterprise networks to two-tier leaf-spine or single-tier Spline cloud networks with east- west traffic patterns scaling across thousands of servers. Arista was the first to introduce this new architectural leaf-spine approach for cloud-based networks and five years later others are still attempting to mimic. Lets review some practical examples.

Ranby Bias in a surprisingly measured blog post about the fact that OpenStack is platform not a product. In the same way that VMware is no longer a single product but a grouping of dozens of products, systems and services.

Unfortunately, none of this exists and probably none of it should have ever been expected since OpenStack won t ever become a unified cloud operating system.

More on the SD-WAN .

This cloud WAN movement, or as some call it software-defined WAN (SD-WAN), is designed to make WAN services easier to consume and manage. It s part of two megatrends in networking, including software-defined networking (SDN) and the consumerization of enterprise technology. This market for enterprise WAN services could be upwards of $7.5 billion by 2020, according to projections

HTTP2 is done. What does it mean for networking engineers and products.

The IESG has formally approved the HTTP/2 and HPACK specifications, and they re on their way to the RFC Editor, where they ll soon be assigned RFC numbers, go through some editorial processes, and be published.

mnot s blog: HTTP/2 is Done

HTTP2 and Networking

• reduces load on network devices by reducing number of concurrent TCP connections
• reduces effectiveness of IDS/IPS through binary encooding (instead of HTTP)
• reduces bandwidth consumption through use of Header Compression
• Encrypted traffic is expected to perform faster than unencrypted traffic, which will drive increase in TLS flows across your DMZ infrastructures.

Cisco ASA SSL VPN has critical flow allowing complete compromise of user data.

A vulnerability in the Clientless SSL VPN portal customization framework could allow an unauthenticated, remote attacker to modify the content of the Clientless SSL VPN portal, which could lead to several attacks including the stealing of credentials, cross-site scripting (XSS), and other types of web attacks on the client using the affected system.

Cisco still has big problems with code quality.
Why does Cisco have a twice yearly update policy ?
