Where have all the global network aggregators gone?

One of the key selling points of SD-WAN is the ability to use a variety of network transport options. Enterprises can select MPLS, dedicated Internet access, business broadband, or wireless broadband, for example – whatever makes the most sense, technically and economically, for each site that needs connectivity. Cultivating a mix of suppliers can allow enterprises to significantly reduce transport costs as well as improve the flexibility of their networks.The growth in SD-WAN deployments over the last four or five years created a sweet spot for Internet transport aggregators, which, frankly, had struggled to break into the enterprise market when it was dominated by traditional MPLS providers.To read this article in full, please click here

BGP Route Reflector Myths

New networking myths are continuously popping up. Here’s a BGP one I encountered a few days ago:

You don’t need IBGP sessions between BGP route reflectors

In general, that’s clearly wrong, as illustrated by this setup:

SSH over bluetooth – cleanly

In my previous two posts I set up a login prompt on a bluetooth serial port and then switched to running SSH on it.

I explicitly did not set up an IP network over bluetooth as I want to minimize the number of configurations (e.g. IP address) and increase the chance of it working when needed.

E.g. firewall misconfiguration or Linux’s various “clever” network managers that tend to wipe out network interface configs would have more of a shared fate with the primary access method (SSH over normal network).

This post is about how to accomplish this more properly.

The problems now being solved are:

• It wasn’t entirely reliable. The rfcomm tool is pretty buggy.

• There was no authentication of the Bluetooth channel. Not as much a problem when doing SSH, but if there are passwords then there could be a man-in-the-middle attack.

• The server side had to remain discoverable forever. So anyone who scans for nearby bluetooth devices would see your servers, and would be able to connect, possibly brute forcing passwords. Not as much of a problem if running SSH with password authentication turned off, but why broadcast the name of a server if you don’t Continue reading

Cisco Brings Webex Collaboration to SD-WAN Cloud Program

The dramatic shift to remote work brought on two years ago by the onset of the COVID-19 pandemic forced companies to almost overnight not only adapt their business models but also to focus on technologies that would allow them and their employees to operate productively and securely. That included embracing connectivity solutions to ensure access to the applications and data critical for getting the job done and collaboration tools to enable employees to more easily work together even if they were located many miles apart. All that has accelerated the growth in such markets at software-defined networking (SD-WAN) and video conferencing and remote communications offerings like Microsoft Teams, Cisco System’s Webex and Zoom. Reliance on such technologies will only grow, given that many companies expect to continue a hybrid work environment even after the pandemic lifts. blog post this week pointed to numbers from Gartner that showed that 48% of employees are expected to work remotely post-pandemic and that hybrid workplaces will become commonplace. “In this new norm, seamless communication and collaboration will be the bare minimum for enterprises to achieve workforce productivity Continue reading

Top 10 outages of 2021

The biggest outages of 2021 had one thing in common: they affected major infrastructure or services providers and, as a result, affected large numbers of enterprises and end users. The lesson? Companies need to be careful about putting all their infrastructure eggs in one basket, or, if they must, to prepare for downtime if that particular service goes down."There needs to be a plan in place," says Angelique Medina, head of product marketing at ThousandEyes, a Cisco-owned network intelligence company that tracks internet and cloud traffic. "Organizations don't need to be at the mercy of the availability of any one particular service."To read this article in full, please click here
