What protocols do the devices use to communicate? For delivering this data one widely used protocol is MQTT. MQTT is a lightweight messaging protocol for pub/sub communication typically used for Machine-to-Machine (M2M) communication. Start the KSQL server. How many devices will be creating information?

In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. During last week’s attack, the attacker was redirecting traffic that belonged to Amazon’s Route 53 DNS servers. In this case, requests for MyEtherWallet.com were answered with the IP address of a fake server in Russia.

Border Gateway Protocol (more commonly known as BGP ) is the routing protocol that makes the internet work. The entire RPKI process stands outside of the BGP routing protocol itself. What that means is that the use of RPKI to validate BGP advertised data doesn’t involve the BGP protocol at all. How Does RPKI Work?

Traditional network monitoring relies on telemetry sources such as Simple Network Messaging Protocol (SNMP), sFlow, NetFlow, CPU, memory, and other device-specific metrics. Your switches, servers, transits, gateways, load balancers, and more are all capturing critical information about their resource utilization and traffic characteristics.

Windows SMBv3 Denial of Service Zero-Day One issue that was not covered widely in the news is a zero-day attack discovered in Microsoft Windows SMBv3, the popular enterprise protocol for file and printer sharing. The POC was able to generate the so called Blue Screen of Death on Windows clients that connects into a compromised SMB server.

But while these protocols have been around for a couple of decades, their potential utility to network operators was initially unrealized, and the process of exposing more value has been a long, gradual evolution. By 1994 BGP4 had become the settled protocol for inter-AS routing. In the beginning…. Kick AS and take names.

Sometimes there is a perception that the embedded solution is about saving money for space and power needed to host the servers, but this is mostly a misunderstanding. The business case can directly compare the saved cost and the estimated cost of space and power for the embedded servers. Let’s have a look at the third case.

While DevOps may indeed be “blind to the network,” achieving visibility will involve a lot of work and contribution from NetOps.

In part 1 of this series, we established that BGP is the protocol used to route traffic across the interconnected Autonomous Systems (AS) that make up the Internet. Your provider probably puts static routes toward you on their side, and redistributes those static routes into their interior gateway protocol (IGP).
