Riverbed’s ‘firework’ CEO, Jerry Kennelly, retires

In 2010, pop singer Katy Perry released a song called Firework. Some of its lyrics are: “Cause baby you're a firework, come on show 'em what you're worth, make 'em go oh, oh, oh.”  In addition to being one of my favorite Katy Perry songs, it’s always reminded me of the firework that was Riverbed and its charismatic and often outspoken CEO, Jerry Kennelly.Riverbed was the face of WAN optimization Riverbed was indeed a firework, as it hit the market with a bang and became the face of WAN optimization. (Note: Riverbed is a client of ZK Research.) Riverbed wasn’t the first vendor in this market — that was Packeteer — but Riverbed evangelized it and became synonymous with the technology.To read this article in full, please click here

MPLS 101 – Dynamic routing with BGP

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

Docker and Java

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
