		<description><![CDATA[Last Saturday marked the 53rd anniversary of the Internet. While the vast majority of its five billion users have been online for less than a decade, the Internet was taken into use on October 29th, 1969, when two computers connected to the ARPANET exchanged a message. Although the Internet has been around for a while, it remained below most people's radar until the late 1990s when the dot com boom started. <a href="https://circleid.com/posts20221101-the-short-history-of-the-internet-from-arpanet-to-the-metaverse">More...</a>]]></description>

		<description><![CDATA[The last few weeks have reinforced the importance of modern communication networks to societies. Health care providers, schools, governments, and businesses all rely on networks that enable us to connect and collaborate remotely. Had we encountered a similar pandemic ten years ago, we would not have been able to continue our activities on the level that is possible today. <a href="https://circleid.com/posts20200327-societies-running-on-quicksand-a-critical-look-at-todays-networks">More...</a>]]></description>

		<link>https://circleid.com/posts20191011_gartner_sdn_has_left_the_building_say_hello_to_network_automation</link>
		<description><![CDATA[In their annual hype cycle on on network technologies, Gartner lists the emerging technologies and an estimate of the timeframe in which they will reach the plateau of productivity. The latest hype cycle on enterprise networking labels Software-Defined Networks (SDN) as an obsolete technology. So on the surface, it would appear that SDN is now semi-officially dead. While most natural scientists accept the Darwinian theories, the technology industry has traditionally been trying to defy evolution. <a href="https://circleid.com/posts20191011_gartner_sdn_has_left_the_building_say_hello_to_network_automation">More...</a>]]></description>

		<link>https://circleid.com/posts20181214_lessons_from_o2_network_outage_the_real_cost_of_manual_processes</link>
		<description><![CDATA[More than 30 million people lost their data connectivity on December 6, 2018, in the United Kingdom as O2's network suffered from a nationwide service outage. Based on several reports, the incident was caused by a human error at Ericsson, the telecoms supplier responsible for operating certain parts of the O2 network. To compensate for the downtime and tarnished reputation, the O2 management is now reportedly seeking damages of up to a hundred million pounds from Ericsson. <a href="https://circleid.com/posts20181214_lessons_from_o2_network_outage_the_real_cost_of_manual_processes">More...</a>]]></description>

		<description><![CDATA[In a recently published Uptime Institute Survey, Uptime Institute found that organizations operating data centers are finding it increasingly difficult to recruit professionals skilled in security, networking, and hybrid technologies. This realization comes at an interesting time, as the monolithic business infrastructure built over the last two decades is now entering a period of transformation. <a href="https://circleid.com/posts20180905_jgetting_on_with_digital_transformation_3_steps_to_making_choices">More...</a>]]></description>

		<description><![CDATA[Digital Transformation (DX) is picking up speed. According to a recent announcement by IDC, the market is expected to grow at a Compounded Annual Growth Rate (CAGR) of 17.9% to reach a whopping 321 billion dollars by 2021. In 2018 alone, IDC expects that 326 billion will be spent on transforming how people and things communicate. Based on these numbers, it looks like Digital Transformation has become the real deal. <a href="https://circleid.com/posts20180423_digital_transformation_in_five_minutes_what_why_and_how">More...</a>]]></description>

		<description><![CDATA[Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) are finally starting to pick up momentum. In the process, it is becoming clear that they are not the silver bullet originally advertised to be. While great for some use cases, emerging technologies like SDN and NFV have been primarily designed for virtual greenfield environments. Yet large service providers continue to run tons of physical network devices that are still managed manually. <a href="https://circleid.com/posts20180213_automation_for_physical_devices_holy_grail_of_service_provisioning">More...</a>]]></description>

		<link>https://circleid.com/posts20170816_the_internet_is_dead_long_live_the_internet</link>
		<description><![CDATA[Back in the early 2000s, several notable Internet researchers were predicting the death of the Internet. Based on the narrative, the Internet infrastructure had not been designed for the scale that was being projected at the time, supposedly leading to fatal security and scalability issues. Yet somehow the Internet industry has always found a way to dodge the bullet at the very last minute. <a href="https://circleid.com/posts20170816_the_internet_is_dead_long_live_the_internet">More...</a>]]></description>

		<description><![CDATA[Harvard Business Review just ran an interesting article on the information security aspects of Internet of Things (IoT). Based on the storyline, the smart city initiatives are doomed to fail unless the security of the IoT devices and the systems will be improved. While security of the digital society is obviously a key concern, I am not entirely convinced that relying on the security of individual devices and systems is the best course of action. <a href="https://circleid.com/posts20170509_iot_devices_will_never_be_secure_enter_the_programmable_networks">More...</a>]]></description>

		<description><![CDATA[As digital transformation has been picking up momentum, leading analysts such as 451 Research have suggested that hybrid multi-clouds and automated DevOps will become key constituents powering enterprises in the new era. At the heart of these enabling technologies lies Lifecycle Service Orchestration (LSO) designed for near-autonomous application deployment across hybrid infrastructures consisting of traditional on-premise data centers and public clouds. <a href="https://circleid.com/posts20170329_networks_the_next_challenge_in_digital_transformation">More...</a>]]></description>

		<description><![CDATA[Open Source (OS) Management and Orchestrations (MANO) is a European Telecommunications Standards Institute (ETSI) initiative that aims to develop a Network Function Virtualization (NFV) MANO software stack, aligned with ETSI NFV. The main goal of MANO is to simplify the onboarding of virtual network components in telco cloud data centers. The initiative has gained impressive momentum among leading Communication Service Providers (CSPs) around the world as part of their NFV programs. <a href="https://circleid.com/posts20170208_nfv_orchestration_without_network_visibility_os_mano_improvements">More...</a>]]></description>

		<link>https://circleid.com/posts20161005_transformation_the_real_business_case_for_nfv_and_sdn</link>
		<description><![CDATA[2016 has seen a steady flow of announcements on successful Network Functions Virtualization (NFV) Proof-of-Concept deployments, mostly focused on virtualizing Customer Premise Equipment (vCPE). This has been a relatively straight forward starting point because unlike many other NFV applications, the vCPE use case does not involve complex activities like having to scale in or out individual services. <a href="https://circleid.com/posts20161005_transformation_the_real_business_case_for_nfv_and_sdn">More...</a>]]></description>

		<link>https://circleid.com/posts20160902_what_is_holding_back_nfv_deployments</link>
		<description><![CDATA[Back in early 2012, the media was all over stack wars that reportedly were taking place between Cisco and VMware. This culminated in VMware's Nicira acquisition in July 2012, paving the way for the coming of software-based networking. Four years later, the market still remains in development mode. Many service providers and enterprises are trying to come to grips with Network Function Virtualization (NFV) and Software-Defined Networking (SDN). <a href="https://circleid.com/posts20160902_what_is_holding_back_nfv_deployments">More...</a>]]></description>

		<link>https://circleid.com/posts20160420_dns_and_stolen_credit_card_numbers</link>
		<description><![CDATA[FireEye announced a new piece of malware yesterday named MULTIGRAIN. This nasty piece of code steals data from Point of Sale (PoS) and transmits the stolen credit card numbers by embedding them into recursive DNS queries. While this was definitely a great catch by the FireEye team, the thing that bothers me here is how DNS is being used in these supposedly restrictive environments. <a href="https://circleid.com/posts20160420_dns_and_stolen_credit_card_numbers">More...</a>]]></description>
