Comcast said to abandon Time Warner merger plan

Comcast has abandoned plans to merge with Time Warner Cable, according to a Bloomberg News report on Thursday.The report quoted “people with knowledge of the matter” and said a formal announcement could be made as soon as Friday.The decision, which was not immediately confirmed by the companies, came a day after the Federal Communications Commission referred the proposed deal to a hearing in front of a judge—a move that had been viewed as a “death sentence” for the plan because of the time and effort it would have taken.The U.S. Department of Justice was also reported to be leaning towards blocking the merger on antitrust grounds should it have received FCC clearance.To read this article in full or to leave a comment, please click here

Open Networking: Worth the Learning Curve

When’s the last time you had the opportunity to learn about a new area of technology? Not just the latest API but something big. With the emergence of open networking, now may be the time to do just that.

Open networking is becoming more wide spread in data centers, partly because of CapEx savings and customer choice from disaggregation of hardware and software. From an operational standpoint, the efficiencies of automating and managing switches like servers may be even more compelling. Those efficiencies – and resulting OpEx savings – are from using a real Linux OS for the network.

As a Linux operating system running network switches, Cumulus Linux presents a learning opportunity for two specific groups of users: network administrators who are new to Linux, and Linux administrators who are new to networking. Open networking represents a radical improvement in network management, but as with most major changes, there’s a learning curve.

Learning a new language (but still saying the same things).

Leaving IOS, NX-OS, or JunOS for Cumulus Linux means rediscovering how to perform tasks that network administrators have been doing the same way for years. This often means tweaking existing knowledge to understand where familiar commands Continue reading

FTC complains retail tracking firm didn’t notify customers

A company that tracked retail store customers through their smartphones without notifying them and without giving them a chance to turn off the tracking has settled a U.S. Federal Trade Commission complaint that it didn’t live up to its privacy promises.Retail tracking firm Nomi Technologies stated in its privacy policy from late 2012 that it would provide a customer opt-out mechanism at stores using its tracking services, thus implying that it would notify customers of the tracking efforts, the FTC said. But the company did not give customers an opt-out option and did not notify customers they were being tracked, the agency said Thursday.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Winds of change blowing in the WAN

In the past few years, enterprise computing has experienced major upheavals brought about by cloud apps, Wi-Fi, mobility, and BYOD. The enterprise WAN, meanwhile, has not evolved much since it was transformed into an MPLS Layer 3 VPN infrastructure more than a decade ago. Things are about change. Based on my experience with customer deployments, more than 50% of enterprise traffic from branches is currently Internet-bound. This is due to outsourcing of utility applications, including email, search, voice, video and collaboration, not to mention cloud application use. Despite this trend, enterprises have resisted using the public Internet to provide remote offices with direct access to cloud applications. This is primarily due to compliance issues, especially in the financial and healthcare industries. Doing so would require extensive security policies at each location and would introduce a management nightmare. The alternative, backhauling traffic to the corporate DMZ, is not feasible. To read this article in full or to leave a comment, please click here

House passes second cyberthreat information-sharing bill

For the second time in two days, the U.S. House of Representatives has voted to pass a bill that would give legal protections to companies that share cyberattack information.The House on Thursday voted 355 to 63 to pass the National Cybersecurity Protection Advancement Act (NCPA), which would protect companies from customer lawsuits after they voluntarily share cyberthreat information with each other and with government agencies.The NCPA is similar in several ways to the Protecting Cyber Networks Act (PCNA), which passed the chamber on Wednesday, despite concerns from some lawmakers that it would allow some customer information to wind up in the hands of surveillance agency the U.S. National Security Agency.To read this article in full or to leave a comment, please click here

Dell takes on Cisco and Juniper with 100G data center switch

Dell this week extended its arsenal of data center Ethernet switches, highlighted by a 100G device with ports dividable into 25G and 50G channels.Twenty-five gigabit and 50G Ethernet are becoming popular options for data centers looking to fill the bandwidth gap between 10G and 40G for server-to-top-of-rack switch connectivity. Products supporting 25/50G are intended to scale network bandwidth to cloud server and storage endpoints, where workloads are expected to surpass the capacity of 10/40G Ethernet links deployed today.To read this article in full or to leave a comment, please click here

Ubuntu, cloud-init, and OpenStack Heat

In this post I’d like to share a couple of things I recently learned about the interaction between cloud-init and OpenStack Orchestration (aka “Heat”). This may be stuff that you already know, but in the interest of helping others who may not know I’m posting it here.

One issue that I’d been repeatedly running into was an apparent “failure” on the part of Heat to properly apply cloud-init configurations to deployed Ubuntu instances. So, using a Heat template with an OS::Nova::Server resource defined like this would result in an instance that apparently wasn’t reachable via SSH (I’d get back Permission denied (publickey)):

resources:
  instance0:
    type: OS::Nova::Server
    properties:
      name: cloud-init-test-01
      image: { get_param: image_id }
      flavor: m1.xsmall
      networks:
        - port: { get_resource: instance0_port0 }
      key_name: lab

Deploying an instance manually from the same image worked perfectly. So what was the deal?

The first thing I learned was that, in some circumstances (more on this in a moment) defaults to injecting SSH keys (like the key named lab specified in the template) to a user account named “ec2-user”. Ah! I’d been using the default “ubuntu” account specified in Continue reading

How your smartphone use could affect your credit

For prospective borrowers who have no credit history, a common problem for immigrants whose credit starts anew when they move to the U.S., economists and startups are using metadata from smartphones to see how reliable a borrower is in other areas of their lives to help determine their likelihood of paying back a loan.A recent article in the New Scientist cites research conducted by Brown University economist Daniel Björkegren and the Entrepreneurial Finance Lab which involved combing through cellphone data of 3,000 borrowers from a Haitian bank to identify such trends as how often they pay their cellphone bills, how quickly they return important phone calls, and travel behavior based on location data.To read this article in full or to leave a comment, please click here

PCE Topology Notifications with OpenDaylight Helium

PCE Topology Notifications with OpenDaylight Helium

by Hariharan Ananthakrishnan, Distinguished Engineer - April 23, 2015

Helium SR3

OpenDaylight released its third maintenance release for Helium last month. Helium SR3 included a lot of bug fixes across OpenDaylight projects. In this blog, I would like to share my experience with PCE topology notifications available in SR3. 

Notifications 

The OpenDaylight controller sal-remote YANG model defines the RPC notification subscription service and data change notification constructs. Change-event notification subscription makes it possible to obtain notifications about data manipulations (inserting, changing, deleting) that are done on any specified part of any specified data store with specific scope. 

PCE Topology Notifications 

PCE topology notification is available in Helium SR3. This feature allows the user to subscribe to a notification stream and listen for asynchronous remote notifications through WebSocket. The changes that get notified are:

  • Addition, update, deletion of Path Computation Clients (PCC)
  • Addition, update, deletion of Label Switched Paths (LSP) 

Test Setup 

The setup has four routers running the IOS XRv 5.3 image, a CentOS 7 VM hosting OpenDaylight Helium SR3, and Packet Design’s SDN Service Assurance Platform acting Continue reading
