MPLS Intro Series – Understanding a Simple LSP

In the previous article, we created an interesting situation with an iBGP configuration.  In that example, we made Edge2 aware of a route via BGP that the intermediary hops would not see. In this article, we will fix this problem using MPLS and label switching. Before getting started, I feel compelled to rename these routers based on their target role in an MPLS our network.

Terms

  • MPLS – multiprotocol label switching – using labels or tags to forward packets over a network (as opposed to traditional destination based routing)
  • LSR – Label switch router (transit router), aka P router, switches labels
  • LER – Label edge router or Edge LSR, often called a PE router, may push (impose) labels
  • LSP – Label Switched Path
  • Push – insert/impose a lable
  • Swap – change a label
  • Pop – remove a label

As we left it in our previous configuration, the router on the right sees a route to 1.0.1.1 via BGP but it cannot reach that destination. It is worth mentioning that I disabled BGP sync (following the last example I shared in the previous article).

LER2#show ip route | inc  1.0.1.1

How edge networking and IoT will reshape data centers

The Internet as we have all known it mirrors the design of old mainframes with dumb terminals: The data path is almost entirely geared toward data coming down the network from a central location. It doesn’t matter if it’s your iPhone or a green text terminal, the fast pipe has always been down, with relatively little data sent up.To read this article in full, please click here(Insider Story)

Multi-cloud monitoring keeps Q2 integrated operations center humming

Five years ago, Q2 had 240 servers. Today it has 8,500 servers. The company spent $150 million over the last five years building out its infrastructure, where it now hosts more than 4 petabytes of user data.“We’ve grown from 1.2 million users to 11.5 million users and reduced downtime to one-fifth of what it was during that same period,” says Lou Senko, CIO of Q2, which provides a digital banking platform for banks and credit unions. [ Related: How to plan a software-defined data-center network.] Headquartered in Austin, Texas, Q2’s cloud-based platform is aimed at helping smaller, community-based financial institutions compete with giants such as Bank of America, Wells Fargo and Citigroup. “Local financial institutions have to compete against some big, big players,” Senko says. “It’s our technology that levels the playing field in the digital world.”To read this article in full, please click here

MPLS Intro Series – Destination Routing

Yes, we are going to talk about destination routing. I know it sounds boring and archaic, and it is. But it is also necessary to contrast against another topic that I intend to introduce. As I scour PacketU, I see a substantial number of page views on articles about segmentation and VRFs. One thing I often tell my customers is that once a VRF-lite implementation reaches a certain scale, the configuration can become unwieldy.

This article is a first in a series where we will discuss MPLS. This technology enables VPNv4 and is a common method of networking. MPLS can connect VRFs without compromising their segmentation characteristics. In this first article, we are going to examine traditional destination-based routing. This is meant to nail down some of the typical behavior of an IPv4 routed network. These characteristics will not go away entirely, but it is important to understand how routing changes as we introduce label switching concepts.

Throughout this series, we will use a common topology. In later articles, we will expand as necessary to introduce the relevant topics.

To illustrate a point, I have pre-configured OSPF on all links and loopback 0 of all routers. In a minute, I will bring Continue reading

Research: Even Password Complexity is a Tradeoff

Stronger passwords are always better—at least this is the working theory of most folks in information technology, security or otherwise. Such blanket rules should raise your suspicions, however; the rule11 maxim if you haven’t found the tradeoff, you haven’t looked hard enough should apply to passwords, too.

Dinei Florêncio, Cormac Herley, and Paul C. Van Oorschot. 2016. Pushing on string: the ‘don’t care’ region of password strength. Commun. ACM 59, 11 (October 2016), 66-74. DOI: https://doi.org/10.1145/2934663

Begin with this simple assertion: complex passwords are primarily a guard against password guessing attacks. Further, while the loss of a single account can be tragic for the individual user (and in some systems, the loss of a single password can have massive consequences!), for the system operator, it is the overall health of the system that matters. There is, in any system, a point at which enough accounts have been compromised that the system itself can no longer secure any information. This not only means the system can no longer hide information, it also means transactions within the system can no longer be trusted.

The number of compromised accounts varies based on the kind of system in view; effectively breaching Continue reading

What is Hops for Hope?

Triangle Hops for Hope is a fundraising event that pairs corporate teams with local breweries to create an original beer and raise money for charity. Teams showcase their creations to hundreds of attendees at an epic beer competition on September 22, 2018 at the Raleigh Beer Garden. It’s the perfect opportunity to mix corporate social responsibility, employee engagement, and support local craft breweries.

All proceeds benefit Children’s Flight of Hope, a 501(c)(3) organization that provides air transportation for children to access specialized medical care. Last year’s event raised more than $70,000 for CFOH!

If you’re in the Raleigh-Durham area and want to buy tickets to this event you can do so Continue reading

IDG Contributor Network: The vital role of technology in the Thai cave rescue mission

Twelve boys and their coach trapped in a cave deep underground with dwindling air and the danger of being flooded by rising water levels. How did a determined international team find and rescue the boys? How did sophisticated geographical information systems (GIS), IoT sensors and 3D simulations assist the rescuers?Tham Luang Nang Non is six mile long underground cave complex in Thailand’s Chiangrai province. A boy’s soccer team was reported missing in July 2018. Thai Navy SEAL divers' found them in a cave that could only be reached after a six hour underground journey in the dark, swimming through narrow tunnels and climbing boulders. An international rescue teams with experts from Thailand, China, Japan, Australia, the US and Britain were able to rescue them.To read this article in full, please click here
