Why Cisco’s new intent-based networking could be a big deal

Scentsy, a $500 million manufacturer and seller of wickless candles, got an early look at what Cisco and some analysts are saying could be the next big thing in the network industry: Intent-based networking.“I think this could be a pretty big shift in terms of the paradigm of network management,” says Kevin Tompkins, network architect at the company. “We’re getting away from managing individual devices and into having a central, globally managed policy, all controlled from one place that pervades through the network.”+MORE AT NETWORK WORLD: Cisco brings intent based networking to the end-to-end network +To read this article in full or to leave a comment, please click here

Banks and Fed sites score as least trustworthy in OTA 2017 security and privacy audit

We frequently hear that we can’t have privacy and security; sadly, that is often still the case as an audit of over 1,000 top websites analyzed for security and privacy practices showed an alarming trend for the third year in a row. The Online Trust Alliance said, “Sites either qualify for the Honor Roll or fail the Audit. In other words, sites increasingly either take privacy and security seriously and do well in the Audit, or lag the industry significantly in one or more critical areas.”There is good news and bad news coming out of the audit (pdf). The good news is that 52 percent of websites, the highest percent in nine years of the annual analysis, qualified for the OTA’s Honor Roll. The flipside is that 46 percent of the websites failed the audit; of those, bank did the worst.To read this article in full or to leave a comment, please click here

When the Internet (Officially) Became the Public Square

Sometimes, well-intended efforts to prevent unacceptable behavior run into the reality of what it means to have an open and free society. That is what happened at the Supreme Court on Monday.

Souvenir Postcard by unknown

The Supreme Court issued an opinion confirming something we at Cloudflare have long believed -- that the First Amendment protects access to the Internet. Using sweeping language, Justice Kennedy compared internet access to access to a street or park, "essential venues for public gatherings to celebrate some views, to protest others, or simply to learn and inquire,” and concluded that "to foreclose access to social media altogether is to prevent the user from engaging in the legitimate exercise of First Amendment rights."

We share this view of the internet as a forum to discuss and debate ideas, and believe that the Court’s opinion is an important reaffirmation of the free speech principles we support.

The Packingham Case

Like many other First Amendment cases, the law at the heart of the Packingham v. North Carolina case presents complex questions about how to protect the community in ways consistent with the right to free speech.

In 2008, North Carolina passed a law making it a Continue reading

Fog computing may be IoT’s computational model

Fog computing and fog networking could fill the latency and range gap in the internet of things (IoT.) For the last couple of years, researchers have been reporting on developments in fog’s role in completing IoT’s ubiquitous connectivity. It is similar to cloud computing architectures but it brings the cloud to the edge to meet the different demands of IoT.The underlying concept is the cloud for some real-time IoT services could be too slow because the quality of service (QoS) specifications for the IoT application exceeds the cloud’s QoS. The solution is to move the cloud out into the network.RELATED: IoT catches on in New England fishing town Low latency and QoS is important in IoT use cases like self-driving vehicles and controlling robots and other control applications that require minimum latency to synchronize, supervise, control and initiate machine actions. Range is important when connecting devices over long distances where hubs and gateways are not locally available.To read this article in full or to leave a comment, please click here

Switching Basics : Private VLANs

Today I am going to talk about “Private VLANs”. By using Private VLANs you can restrict the specific port from the network and it can only communicate with the uplink port with which it connects.

We have two kind of VLANs; One is Primary VLAN and other is Secondary VLANs. Primary VLANs is a type of VLAN which is used to forward frames downstream to all Secondary VLANs.while Secondary VLANs are further divided in to the 2 types and these types are :

Isolated VLANs : 
As name suggested, it is isolated from all the port except the ports in the Primary VLAN or you can say the isolated VLAN port can only talk with the uplink port and will be isolated from the other ports in the network.

Community VLANs:
As name suggest. if two ports are in the community they can talk to each other and talk to the uplink port as well but not able to talk to the other members of the VLANs. They are restricted to have a communication with the isolated VLANs in the network.

Fig 1.1- Private VLANs

Most common question what i am thinking now;

If two different Ports Continue reading

IPv4 route lookup on Linux

TL;DR: With its implementation of IPv4 routing tables using LPC-tries, Linux offers good lookup performance (50 ns for a full view) and low memory usage (64 MiB for a full view).

During the lifetime of an IPv4 datagram inside the Linux kernel, one important step is the route lookup for the destination address through the fib_lookup() function. From essential information about the datagram (source and destination IP addresses, interfaces, firewall mark, …), this function should quickly provide a decision. Some possible options are:

  • local delivery (RTN_LOCAL),
  • forwarding to a supplied next hop (RTN_UNICAST),
  • silent discard (RTN_BLACKHOLE).

Since 2.6.39, Linux stores routes into a compressed prefix tree (commit 3630b7c050d9). In the past, a route cache was maintained but it has been removed1 in Linux 3.6.

Route lookup in a trie

Looking up a route in a routing table is to find the most specific prefix matching the requested destination. Let’s assume the following routing table:
