Sizing up the three popular Internet TV streaming sticks

If you’re like most folks, the back of your home entertainment center is a hive of HDMI cables, USB cords and power adaptors, not to mention the HDMI switchers necessary to cope with this cornucopia of entertainment providers. Thankfully, there is a solution: The increasingly popular streaming stick.

These Internet TV streaming devices will be the savior of every gadget-obsessed, cable-cluttered geek out there. These chewing gum-sized streaming devices can pipe the whole wide, weird and wonderful Internet into your television, with a lot less of the cable mess than you’re dealing with now.

Currently available in one of three flavors—Roku's Stick ($50), Google's Chromecast ($35), and Amazon's Fire Stick ($39)— these three devices can deliver pretty much any online content you could wish for directly to your living room. Here's a look at what these sticks have to offer:

How can router decide so fast?

How does Internet work - We know what is networking

Cisco created all sorts of different magic inside their boxes that optimize forwarding processing of packets. Main router function is fairly self-explanatory. Router performs IP forwarding more often called IP routing. IP routing is process of deciding where to send the packet after it was received.       IP Routing explained in detail Logic behind IP forwarding is listed in steps here with the assumption it will be an IPv4 packet that was received. This is process switching explained in 11 steps: A frame enters the one of router’s interface First thing that router does is to check frame

27 – Bis-Bis – Stateful Firewall devices and DCI challenges – Part 1 (cont)

Back to the recent comments on  what is “officially” supported or not ?

First of all, let’s review the different Firewall forwarding mode officially supported

ASA cluster  deployed inside a single data center:

Firewall forwarding mode within single DCFig.1 Firewall forwarding mode within a single DC. Please note the firewall routed mode supported with the Layer 2 load balancing (LACP) Spanned Interface mode.

When configured in Routed mode (e.g. default gateway for the machines), the same ASA identifiers IP/MAC are distributed among all ASA members of the cluster. When the ASA cluster is stretched across different locations, the Layer 2 distribution mechanism facing the ASA devices is achieved locally using pair of switches (usually leveraged the a Multi-chassis EthernetChannel technique such as VSS or vPC).

Subsequently the same virtual MAC address (ASA vMAC) of the ASA cluster is duplicated on both sites and as the result it hits the upward switch from different interfaces.

 

 

 

 

 

 

 

 

 

 

Fig.2 ASA and duplicate vMAC address

When the ASA cluster runs the firewall routed mode with Spanned interface method, it breaks the Ethernet rules due to the duplicate MAC address, with risks of affecting the whole network operation. Consequently Continue reading

SDN Router @ Spotify on Software Gone Wild

Imagine you need a data center WAN edge router with multiple 10GE uplinks. You’d probably go for an ASR or a MX-series router, right? How about using a 2 Tbps ToR switch and an SDN solution to make it work with full Internet routing table?

The Importance of Product Education

brainI learned something new this afternoon. While other users of this product were already aware of it, I was not. This is something that is specific to the Wi-Fi community, but there is a larger point affecting all practitioners of technology that I will attempt to illustrate in this post.

The Problem

I have been doing a lot of wireless surveys lately. These particular surveys have been large enough to require two engineers to be on site. We’ll divide up the location by floors or sections in order to get the job done in less time. These particular surveys are in place assessments, so we aren’t putting survey AP’s up on poles and measuring signal strength, determining attenuation of walls, etc. We’re simply measuring the signal of all AP’s in place and making recommendations based on the requirements of the business(e.g. moving to support voice at 5GHz or location based services). In addition to using a survey tool, which in our case is Ekahau’s Site Survey, we are also doing spectrum analysis at various points within the given facility with Metageek’s Wi-Spy DBx hardware and Chanalyzer software.

The spectrum analysis portion is where my problem resided. I happen to have a pair Continue reading

Golang for Network Ops

I get asked quite often where the traditional network engineer / network ops should start if they want to broaden their horizons with better code hacking skills or they have spent the last 20 years using Perl scripts or more recently Python and need a change. The answer is easy, Golang. At Socketplane, we all ditched the past couple of ... The post Golang for Network Ops appeared first on NetworkStatic | Brent Salisbury's Blog.

Open vSwitch to gain network virtualization

Developers of Open vSwitch, the open source networking component for hypervisors, are adding network virtualization capabilities to the code. According to this post in Network Heresy, the developers are working on the Open Virtual Network (OVN) project which is intended to bring native support for virtual network abstractions, such as virtual Layer 2 and Layer 3 overlays and security groups, to OVS.The design goal of the OVN developers is to have a production quality implementation that can operate at significant scale, state the authors of the post, two of whom work at VMware. A third is CEO of DevOps start-up Socketplane, and the fourth is the chief technologist at Red Hat.To read this article in full or to leave a comment, please click here

Open Networking Accelerated with Help from Experts

Any major technology shift in the data center, such as open networking, is about much more than just swapping out today’s hardware and software for the better, faster, more affordable next generation products.

It’s just as much about people and their processes – and the learning curve required for accelerated success as the new technology takes hold.

Open networking is at this stage now. It’s broadly seen as an inevitable tech trend as data center architectures change to a software-driven model to resolve challenges around agility, scalability and cost. The trend is reminiscent of the transformation of the server infrastructure that gave customers choice, better tools, and TCO improvements – and that allowed data center system admins to develop new technical skills along the way.

2015 is the year when open networking will expand from big cloud operators and early adopters to organizations of all sizes. The technology is proven, and now there’s support for layer 2, layer 3 and layer 3 overlay architectures.

So what does that mean to the people who keep all the world’s data centers running? It’s an opportunity to expand their technical horizons (and their contributions to the business) by learning how to leverage open Continue reading

Connecting Edge Router to physical LAN using VMware NSX

On a previous post an Edge router has been deployed and configured with OSPF. Now the edge router must be connected to external networks: An uplink interface needs to be bound to a PortGroup not configured for NSX. In other words a PortGroup named 172.31.30./27 has been manually added to the same Distributed vSwitch used […]

Plexxi Is Growing Again

We’re dodging scaffolding and flying paint cans around the office in our Nashua, N.H. headquarters this week as work crews knock down walls to expand our current office space to keep pace with Plexxi’s growth. Since Rich Napolitano was announced as CEO two months ago, the company has grown 20 percent (and we’re hiring across the board in development, sales, support and marketing!).

The office expansion will increase our headquarters footprint by 5,600 square feet to 23,000 square feet. The new space that’s being set up this week will house our growing sales, marketing and business operations. It will also feature customer meeting and demonstration areas that will be up and running soon.

We’ll keep you posted on our growth and promise to share more pictures once the space is complete. Now if I could only figure out where my desk was moved to…
