MPLS Transport Profile (MPLS-TP) Basic Explanation and Key Points
MPLS Transport Profile (MPLS-TP) Multi-Protocol Label Switching Transport Profile (MPLS-TP) is a new technology developed jointly by the ITU-T and the IETF. The key motivation is to add OAM functionality to MPLS in order to monitor each packet and thus enable MPLS-TP to operate as a transport network protocol. Motivations for MPLS Transport Profile […]

Some confusing language in the 0day debate
As revealed in last week's CIA #Vault7 leaks, the CIA has some 0days. This has ignited the debate about whether organizations like the CIA should be disclosing these 0days so that vendors can fix them, rather than "stockpiling" them. There seems to be some confusion about language.Stockpile
The word "stockpile" has multiple connotations, as shown below:
This distorts the debate. Using the word "stockpile" strongly implies "reserve for use" at some time in the future. This prejudices the debate. If the the 0day is sitting on a shelf somewhere not being used, then it apparently has little value for offense, and thus, should be disclosed/patch for defense.
The truth is that that government does not buy 0days to sit on the shelf. With few exceptions, it buys 0days because it plans to use them in an offensive operation. This was described in that recent RAND report:
It's the sellers who might keep 0days on the shelf, because the buyers have no immediate need. It's not the government buyers who are stockpiling.
Words like "stockpiling", "amassing", or "hoarding" also bring the connotation that the number is too big. Words like "hoarding" bring the connotation that the government is doing something Continue reading
The Internet’s Gilded Age
The rise of the Internet has heralded rapid changes in our society. The opportunities presented by a capable and ubiquitous communications system and a global transportation network have taken some corporations from the multinational to the status of truly global mega-corporation. There are a handful of large scale winners in this space and many losers. But this is not the first time we’ve witnessed a period of rapid technological and social change.White Box Switches Have Grown Up
White box switches have come a long way. The recent activities in OCP validate the vision and progress of white box switches, and more importantly it is clear that this trend is progressing from data centers to enterprises. I remember when Zeus Kerravala wrote in his 2016 article, “White Box Switches are Now Ready for Prime Time,” he pointed out three important advantages:
– Cost and reliability
– Features and capabilities
– Network operations
As a NOS vendor, we see NOS is being adopted into production environments. Even though there are still challenges with white box switches going from data centers to other segments, there is no doubt the networking industry has moved onto the path toward white box switches.
From what we saw at OCP Summit, the overall reliability of white box switches is improving, and in many cases, they are more reliable than some brand-name hardware. We can now find dozens of vendors providing white box switches. These vendors come with different backgrounds and carry out different approaches in designing their hardware platforms. In OCP, we can see three clearly different types of vendors providing white box switches:
- Brand name vendors, such as HPE and Dell. This group Continue reading
