Middleboxes and the End-to-End Principle

The IP suite was always loosely grounded in the end-to-end principle, defined here (a version of this paper is also apparently available here), is quoted in RFC2775 as:

The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the endpoints of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible. … This principle has important consequences if we require applications to survive partial network failures. An end-to-end protocol design should not rely on the maintenance of state (i.e. information about the state of the end-to-end communication) inside the network.

How are the Internet and (by extension) IP networks in general doing in regards to the end-to-end principle? Perhaps the first notice in IETF drafts is RFC2101, which argues the IPv4 address was originally a locater and an identifier, and that the locater usage has become the primary usage. This is much of the argument around LISP and many other areas of work—but I think 2101 mistates the case a bit. That the original point of an IP address is to locate a topological location in the network is Continue reading

Google Team Refines GPU Powered Neural Machine Translation

Despite the fact that Google has developed its own custom machine learning chips, the company is well-known as a user of GPUs internally, particularly for its deep learning efforts, in addition to offering GPUs in its cloud.

At last year’s Nvidia GPU Technology Conference, Jeff Dean, Senior Google Fellow offered a vivid description of how the search giant has deployed GPUs for a large number of workloads, many centered around speech recognition and language-oriented research projects as well as various computer vision efforts. What was clear from Dean’s talk—and from watching other deep learning shops with large GPU cluster …

How IBM wants to bring blockchain from Bitcoin to your data center

At its InterConnect conference in Las Vegas this week, IBM is announcing new features for its open source cloud-hosted blockchain service in an attempt to bring this distributed database technology from its initial use of powering Bitcoin to a broader market, including the financial services industry.Blockchain is a distributed database that maintains a continually growing list of records that can be verified using hashing techniques. Vendors such as IBM and Microsoft are attempting to commercialize it by offering customers a platform for hosting their own implementations. Analysts say the market to do so is just emerging.+MORE AT NETWORK WORLD: The future of networking is in a white box | How to get the most out of data and services in a multi-cloud world +To read this article in full or to leave a comment, please click here

Pwn2Own 2017: Your stuff as mincemeat

They came from miles around to carry out a hallowed, decade-long mission: To eat your lunch. The security researchers assembled at the Pwn2Own 2017 hacking competition, sponsored by Trend Micro, and occasionally grouped together, then performed essentially zero-day exploits (at least by the rules, heretofore unknown) on your favorite stuff, such as Windows, MacOS and Linux. Smoldering pits in the screen were left, as teams collected cash prizes and creds. RELATED: How San Diego fights off 500,000 cyberattacks a day For giggles and grins, a Type 2 Hypervisor, VMWare Workstation was also left for shrapnel, one of the first times a hypervisor has been penetrated by a virtual machine in this way. It wasn’t a cascade effect, but rather a shot across the bow. I suspect there are more ways to penetrate a foundational hypervisor, too, but they haven’t been seen in captivity to my knowledge. To read this article in full or to leave a comment, please click here
