In my last post on securing BGP, I said—
The CAP theorem post referenced above is here.
Before I dive into the technical issues, I want to return to the business issues for a moment. In a call this week on the topic of BGP security, someone pointed out that there is no difference between an advertisement in BGP asserting some piece of information (reachability or connectivity, take your pick), and an advertisements outside BGP asserting this same bit of information. The point of the question is this: if I can’t trust you to advertise the right thing in one setting, then why should I trust you to advertise the right thing in another? More specifically, if you’re using Continue reading

Dealing with large datasets is often daunting. With limited computing resources, particularly memory, it can be challenging to perform even basic tasks like counting distinct elements, membership check, filtering duplicate elements, finding minimum, maximum, top-n elements, or set operations like union, intersection, similarity and so on
Probabilistic data structures can come in pretty handy in these cases, in that they dramatically reduce memory requirements, while still providing acceptable accuracy. Moreover, you get time efficiencies, as lookups (and adds) rely on multiple independent hash functions, which can be parallelized. We use structures like Bloom filters, MinHash, Count-min sketch, HyperLogLog extensively to solve a variety of problems. One fairly straightforward example is presented below.
We at CleverTap manage mobile push notifications for our customers, and one of the things we need to guard against is sending multiple notifications to the same user for the same campaign. Push notifications are routed to individual devices/users based on push notification tokens generated by the mobile platforms. Because of their size (anywhere from 32b to 4kb), it’s non-performant for us to index Continue reading

Sometimes you need to rely on more than faith to protect yourself, your data and resources.
Today Brocade and Ruckus Wireless have taken an important step toward our joint vision of creating a new type of networking company - a company with the strategy, products, talent, and focus needed to deliver the solutions that customers need in order to thrive in today’s era of digital transformation. We’re very excited to let you know that this morning we announced Brocade’s intention to acquire Ruckus, a pioneer in the wireless infrastructure market.
The combination of Brocade and Ruckus will create a pure-play networking company that has market-leading solutions spanning from the most critical part of the data center to the wireless network edge. Wireless technology is a critical element in modern, New IP network architectures. Ruckus’ wireless networking solutions will add a high-growth and highly complementary product category to Brocade’s current storage, data center, campus and mobility networking solutions. The combined company will be better positioned to deliver networks that are platforms for innovation for our customers.
The new company will start with an impressive leadership position in highly strategic areas that we plan to build from:
The IEEE 802.3 committee isn’t very good at getting standards work completed so there is a pre-standards body called the Ethernet Alliance. Its like a “pre-meeting meeting” (yes, we have all had those) for Ethernet standards where vendors thrash out most of the obvious stuff so that the committee has less work to consider and, theoretically, should […]
