This past fall, Juniper introduced a new Cloud CPE solution, an exciting new addition to our Network Functions Virtualization (NFV) portfolio. This new solution empowers service providers to simplify the service creation process, reducing the operation from months to minutes by completely automating the entire service delivery workflow.  Service providers can now introduce managed business services such as virtual CPE products, delivered on-premises or in the cloud, with a new level of speed and agility that greatly improves their value to enterprise customers.

In order to support multiple tenants on a physical server both virtualization and containers comes to the rescue. This blog discusses the following three different architecture models and compares the benefits and disadvantages of each of the model:

  1. Virtualization
  2. Containers
  3. Tenant aware application

Field trials of high density DWDM router interfaces

by Juniper Employee ‎05-27-2016 09:08 AM - edited ‎05-27-2016 02:41 PM

IMG_1395_roated_right.jpgOur customers have been carrying out field trials and deployments of our latest 100GE DWDM coherent interfaces. In this new generation, a CFP2-ACO [1] module containing the tunable coherent optics plugs into an MX MIC or a PTX PIC containing the DSP, framer/deframer and FEC encoder/decoder.

From combating ransomware to managing credentials to overseeing system migrations, IT teams at small and mid-market companies have a lot on their plates – and too few resources. When it comes to provisioning networks, the hardware choices can be overwhelming, especially when all switches look more or less the same.

 

So what makes one box better than any other?

Junos Fusion Enterprise.png

We announced Junos Fusion Enterprise last year when we launched Juniper Networks® Unite, our enterprise network solution that helps customers deploy a cloud-enabled enterprise. Junos Fusion Enterprise is a foundational element of Unite that supports its simplicity pillar; previously, I've described its unique simplification features in my Simplification Trifecta blog post.

 

We recently announced two new EX Series models, the EX2300, an entry-level 1GbE access switch, and the EX3400, a mid-range 1GbE access switch, that are both Junos Fusion Enterprise capable, joining the EX4300 as satellite device options.

At a time when network complexity is driving operators to automate all aspects of networking, the push for simple no-configuration routing that is “good enough” to work in millions of homes and small businesses is driving a desire to standardize Babel in the IETF....   One idea to handle IPv6 multi-homing well is source-destination routing; that’s being discussed more in RTGWG, including a Virtual Interim (just call in) focusing on it on May 31.

You Light Up My Life: Luminescence Coming to OFC 2016

by Juniper Employee ‎03-16-2016 11:52 AM - edited ‎03-16-2016 11:57 AM

OFC 2016 is less than a week away, and I’m excited to see what innovative new photonic technologies will be unveiled at this year’s show.

In years past, the show introduced some game-changing innovations, such as 10G modem technology, the pre-cursor to coherent receivers; ultra-low loss fiber that can be tied in a knot which potentially eliminates residential fiber installation issues; and flex-spectrum ROADMs, paving the way for super-channel DWDM systems.

implifying your DC Network has many advantages for the IT Department: It becomes easier to handle, easier to upgrade, you need less training efforts and have more time to focus on high value activities like analytics and optimization. Simplification is an important step on the journey to the cloud.

It’s only a few days until the MPLS World Congress in Paris, so I thought I’d say some words about our live demo of NorthStar, our SDN WAN Controller.

 

One of the key applications of NorthStar is the creation of diversely routed pairs of LSPs. These are used to underpin services that have high SLA requirements - if something fails along the path of one LSP, the other is unaffected and so can still carry traffic. This is illustrated in Figure 1.

 

Figure 1: are these LSPs really diverse?Figure 1: are these LSPs really diverse?

But how do we know whether the LSPs are truly diverse? - they may appear to be diverse at the IP/MPLS layer, but there may be some fate-sharing in the underlying optical layer.

 

One option is to configure Shared Risk Link Group (SRLG) tags on the interfaces on routers P1, P2, P4 and P5 that share fate. These SRLGs are carried in the IGP alongside all the other link-state information and communicated to the NorthStar via IGP or BGP-LS peering. Another option is to configure the NorthStar conroller with SRLG info via the northbound REST API. However, in the conference, I will talk about a third option: a standards-based YANG-based data model [1] that enables an optical NMS to communicate essential information about the optical layer to the NorthStar controller. This allows the optical NMS to advertise Shared Risk Link Groups (SRLGs), so that NorthStar is aware of any fate-sharing. This dynamic approach provides a higher degree of automation than manually configuring SRLGs on the router interfaces, bearing in mind that the SRLGs could change over time, for example if the routing of paths through the optical network changes over time.

 

In Figure 2, the left-hand side shows details of the underlying optical infrastructure. As can be seen, the link between P1 and P4 shares fate with the link between P2 and P5, as they use the same optical fibre between optical nodes O3 and O4.

 

Figure 2: the left-hand side shows details of the underlying optical infrastructure. The right-hand side shows the resulting set of abstract links that are advertised by the optical controller to the packet controllerFigure 2: the left-hand side shows details of the underlying optical infrastructure. The right-hand side shows the resulting set of abstract links that are advertised by the optical controller to the packet controller

The optical controller describes the connections that it provides to the client packet layer in the form of abstract links, shown on the right-hand side of the slide. Abstract links allow key information (for example SRLGs and delay metrics) to be communicated to the packet controller, while hiding information that is not of interest to it, for example intermediate optical nodes in the end-to-path.

 

Let’s look at another example, this time with screen-shots from the NorthStar GUI. In Figure 3, the upper part of the network map shows the routers. The lower part shows abstract links and nodes that have been advertised by the optical controller. The table at the bottom of the screen shows SRLGs that have been advertised by the optical controller to NorthStar. The highlighted SRLG shows that the vmx10-p12 to vmx20-p22 link and the vmx10-p11 to vmx10-p21 link share fate (shown in yellow on the map).

 

Figure 3: NorthStar knows from the information it receives from the optical controller that the two highlighted links share fateFigure 3: NorthStar knows from the information it receives from the optical controller that the two highlighted links share fate

Figure 4 shows what happens if we ask NorthStar to perform a diverse path calculation between vmx10 and vmx20, taking SRLGs into account. As can be seen, NorthStar routes one of the LSPs via vmx30-p31, so that the two LSPs are truly diverse.

If you would like to hear more, come to my talk during the conference on Friday morning. Also we will be having live demos of the scheme on our exhibition booth for the whole duration of the conference. See you in Paris!

We know the Internet has changed our lives. The world fits in our pocket. We video chat across the globe. We share and connect with friends instantly. Our office follows us. These are all made possible by connecting through a network. Our lives will continue to change. Transportation. Education. Healthcare. Law enforcement. All of these will be entirely different because networks will transform them. These transformations have already begun. In 2016, I expect to see the networking space specifically evolve in a few ways.

As we have moved out of 2015 and into 2016, we’ve had time to reflect on where the industry’s headed and what changes took place last year. The number of Internet users continues to climb 7.2 percent year over year with no end in sight. It is currently at 3.17 billion, which is up from 2.94 billion in 2014(1). The proliferation of smart devices, cell phones, and tablets are penetrating the far reaches of the globe, enlightening new people everyday.
