BGP in EVPN-Based Data Center Fabrics – Take 2
My BGP in EVPN-Based Data Center Fabrics blog post generated numerous comments from engineers disagreeing with my views on using IBGP-over-EBGP.
As usual, there were three kinds of comments:

In our last post we talked about how to make the MPLS control plane more dynamic by getting rid of static LSPs and adding in LDP to help advertise and distribute LSPs to all MPLS speaking routers. However – even once got LDP up and running, we still had to tell the routers to use a given LSP. In the last post, we accomplished this by adding recursive static routes in the inet.0 table to force the routers to recurse to the inet.3 table where the MPLS LSPs lived. In this post, we’re going to tackle getting rid of the static routes and focus on replacing it with a dynamic routing protocol – BGP.
So to start off with, let’s get our lab back to a place where we can start. To do that, we’re going to load the following configuration on each router show in the following lab topology…
interfaces {
ge-0/0/0 {
enable;
unit 0 {
family inet {
address 10.2.2.0/31;
}
}
}
ge-0/0/1 {
enable;
unit 0 {
family inet {
address 10.1.1.0/31;
}
family mpls;
}
}

Improved Docker Container Integration with Java 10
Many applications that run in a Java Virtual Machine (JVM), including data services such as Apache Spark and Kafka and traditional enterprise applications, are run in containers. Until recently, running the JVM in a container presented problems with memory and cpu sizing and usage that led to performance loss. This was because Java didn’t recognize that it was running in a container. With the release of Java 10, the JVM now recognizes constraints set by container control groups (cgroups). Both memory and cpu constraints can be used manage Java applications directly in containers, these include:
- adhering to memory limits set in the container
- setting available cpus in the container
- setting cpu constraints in the container
Java 10 improvements are realized in both Docker for Mac or Windows and Docker Enterprise Edition environments.
Container Memory Limits
Until Java 9 the JVM did not recognize memory or cpu limits set by the container using flags. In Java 10, memory limits are automatically recognized and enforced.
Java defines a server class machine as having 2 CPUs and 2GB of memory and the default heap size is ¼ of the physical memory. For example, a Docker Enterprise Edition installation has 2GB of memory and Continue reading

While the Candidate Pack (information about the CEO position) has been available for download on the link above during the whole open call, we have received input from our community asking us to make the Candidate Pack available also on a regular URL outside the search firm’s portal. Accordingly, for your convenience, we have now made it available on the following link as well:
https://www.internetsociety.org/wp-content/uploads/2018/04/Internet-Society-CEO-Succession.pdf
Please, distribute this call to potential candidates who may be interested so that they can apply before the upcoming deadline.
The ongoing open call for candidates will result in a long list of candidates. Taking the long list as a starting point, the whole board (at this point the search committee has already done Continue reading
