Next Generation Multicast – NG-MVPN

Introduction

Multicast is a great technology that although it provides great benefits, is seldomly deployed. It’s a lot like IPv6 in that regard. Service providers or enterprises that run MPLS and want to provide multicast services have not been able to use MPLS to provide multicast  Multicast has then typically been delivered by using Draft Rosen which is a mGRE technology to provide multicast. This post starts with a brief overview of Draft Rosen.

Draft Rosen

Draft Rosen uses GRE as an overlay protocol. That means that all multicast packets will be encapsulated inside GRE. A virtual LAN is emulated by having all PE routers in the VPN join a multicast group. This is known as the default Multicast Distribution Tree (MDT). The default MDT is used for PIM hello’s and other PIM signaling but also for data traffic. If the source sends a lot of traffic it is inefficient to use the default MDT and a data MDT can be created. The data MDT will only include PE’s that have receivers for the group in use.

Draft Rosen is fairly simple to deploy and works well but it has a few drawbacks. Let’s take a look at these:

ICANN seeks opinion on legality of ‘.sucks’ registration process

The body that manages the Internet domain name system has asked regulators in the U.S. and Canada to comment on the legality of the high prices and procedures used by Vox Populi Registry for registrations of ‘.sucks’ domain names by trademark owners.The move Thursday by the Internet Corporation for Assigned Names and Numbers (ICANN) follows a recent letter from its Intellectual Property Constituency, which asked that the rollout of the new .sucks gTLD (generic top-level domain) should be halted.The IPC, which represents the holders of trademarks and related intellectual property, described the registration scheme for the domain as predatory and designed to exploit trademark owners. It said Vox Populi had announced it would charge trademark owners US$2,499 and above to register domain names during the early ‘sunrise’ period.To read this article in full or to leave a comment, please click here

US blocks Intel from selling Xeon chips to Chinese supercomputer projects

U.S. government agencies have stopped Intel from selling microprocessors for China’s supercomputers, apparently reflecting concern about their use in nuclear tests.In February, four supercomputing institutions in China were placed on a U.S. government list that effectively bans them from receiving certain U.S. exports.The four institutions, which include China’s National University of Defense Technology, have been involved in building Tianhe-2, the world’s fastest supercomputer, and Tianhe-1A.The two supercomputers have been allegedly used for ”nuclear explosive activities,” according to a notice posted by the U.S. Department of Commerce.To read this article in full or to leave a comment, please click here

IBM, Fujifilm show tape storage still has a long future

IBM and Fujifilm have figured out how to fit 220TB of data on a standard-size tape that fits in your hand, flexing the technology’s strengths as a long-term storage medium.The prototype Fujifilm tape and accompanying drive technology from IBM labs packs 88 times as much data onto a tape as industry-standard LTO-6 (Linear Tape-Open) systems using the same size cartridge, IBM says. LTO6 tape can hold 2.5TB, uncompressed, on a cartridge about 10 by 10 centimeters (4 by 4 inches) across and 2 centimeters thick.The new technologies won’t come out in products for several years and may not be quite as extreme when they do, but the advances show tape can keep getting more dense into the future, said Mark Lantz, manager of IBM’s Advanced Tape Technologies Group.To read this article in full or to leave a comment, please click here

Jawbone’s UP3 will ship April 20 — just don’t take it swimming

Jawbone’s latest activity tracker, the UP3, will finally ship April 20 after being delayed for months, though without a core feature the company had hoped for.Water resistance issues led to delays in the product’s launch, Jawbone said Thursday. The company was hoping for a product that could be submerged up to 10 meters underwater, but Jawbone couldn’t achieve that. The shipping product will withstand everyday splashing and showers, like other trackers, but will be unsuitable for swimming or submerged use, Jawbone said in a blog post.Customers who want to cancel their pre-order can do so with no charge, the company said. Jawbone had originally planned on launching the UP3 late last year.To read this article in full or to leave a comment, please click here

Apple trying to discourage Apple Watch lines at launch

In many ways, new Apple product launches have become ritualistic affairs. The night before a new product goes on sale, enthusiastic consumers line up outside of Apple retail stores in lines that sometimes stretch out for blocks on end.With the Apple Watch slated to launch in a few weeks, that ritual may finally be coming to an end. According to an internal Apple memo obtained by Business Insider, Apple retail head Angela Ahrendts wants to put the days of waiting in line in the past, all in the interest of enhancing the customer shopping experience. To read this article in full or to leave a comment, please click here

How to overcome 3 hybrid cloud integration challenges

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

Companies adopting cloud technologies often end up with a public/private hybrid approach that balances business needs with infrastructure goals, and while the end result provides numerous benefits, hybrid clouds can result in integration challenges. But with the right planning and the strategies below, connecting cloud applications can be done easily and effectively:

1. Understand and work around individual SaaS API limitations

Surprisingly, not all APIs offer full create, read, update and delete (CRUD) operations on all of their entities, often exposing just a subset of the full data model. Always be sure to know what data entities are available and what operations you can perform on them before committing to any hybrid integration project, even when the API exposes the entity you are looking for and the operation you want.

What’s behind Microsoft’s not-so-crazy startup spending spree

Microsoft so far this year has been the most acquisitive company in enterprise IT, snapping up at least four firms on top of four others that it bought in the last two months of 2014. And while the buyouts might at first glance appear scattershot – we’re talking text analysis, calendaring and digital pen startups among others -- there does seem to be a grand plan here.Our regularly updated Enterprise Networking & IT Acquisition Tracker shows through the first calendar quarter that Microsoft has announced more than twice as many buyouts as any other company (not that all acquisitions are immediately made public and taking into account that our tracker is focused on enterprise-related acquisitions -- Google has bought at least four consumer-oriented companies).To read this article in full or to leave a comment, please click here
