Social media is one of the most used sites all over the world used by most mobile users counting to hundreds of millions of users. It provides different services to its users. It can be used as a fun site to upload images and videos, as a means of communication, as a way to meet different people of different beliefs and cultures all over the world, to learn and explore new and different things, and also as a business place. You reading this article also includes you among the social media users and you’ll know that there is a lot to benefit from using these sites. Let’s consider some of the most popular social media sites and what you should know about them.
- Facebook: This is one of the most popular social media sites used by over 350 million users. You get to be friends with other Facebook users. In this case, a friend request would be sent and it has to be accepted by the receiver. It is a platform where people mostly share images and videos of various content under various genres. You can always access your genre of interest by using the search icon shaped like a Continue reading
Should We Use LISP?
LISP started as yet-another ocean-boiling project focused initially on solving the “we use locators as identifiers” mess (not quite), and providing scalable IPv6 connectivity over IPv4-only transport networks by adding another layer of indirection and thus yet again proving RFC 1925 rule 6a. At least those are the diagrams I remember from the early “look at this wonderful tool” presentations explaining for example how Facebook is using LISP to deploy IPv6 (more details in this presentation).
Somehow that use case failed to gain traction and so the pivots1 started explaining how one can use LISP to solve IP mobility or IP multihoming or live VM migration, or to implement IP version of conversational learning in Cisco SD-Access. After a few years of those pivots, I started dismissing LISP with a short “cache-based forwarding never worked well” counterargument.

Micro-segmentation and Beyond with NSX Firewall
VMware-based workload environments are the norm in private clouds for enterprise-class customers. 100%[1] of Fortune 500 companies deploy vSphere/ESXi. Further, ~99% of Fortune 1000 and ~98%[2] of Forbes Global 2000 companies deploy vSphere/ESXi. VMware’s deep presence in enterprise private clouds has made NSX Firewall the preferred micro-segmentation solution for these enterprises.
Below, we expand on how the NSX Firewall has developed its prominent position in enterprise private clouds.
Agentless and Agent-based Operation
Virtualized x86 workloads on hypervisors represent ~80%[3] of all enterprise workloads. VMware’s hypervisor-based micro-segmentation solution – NSX Firewall – is the preferred agentless solution for such workloads because of the solution’s tight integration with the rest of the VMware eco-system.
~15% of workloads at enterprises are x86-based (Windows, Linux) but not virtualized. The NSX Firewall handles these workloads with NSX agents.
~5% of workloads at enterprises are non-x86-based. VMware provides an (agentless) layer 2-7 gateway firewall that supports micro-segmentation for these workloads. Note that the gateway firewall eliminates the need for integration with physical switches, routers, and load-balancers.
Between these mechanisms, 100% of all workloads in the private cloud are protected. In practice, given VMware’s penetration of enterprises, VMware’s agentless solutions apply to the vast Continue reading
Hedge 121: Computing in the Network with Marie-Jose Montpetit
Can computation be drawn into the network, rather than always being pushed to the edge of the network? Taking content distribution networks as a starting point, the COIN research group is looking at ways to make networks more content and computationally aware, bringing compute into the network itself. Join Alvaro Retana, Marie-Jose Montpetit, and Russ White, as we discuss the ongoing research around computing in the network.
Is Network Observability Different from Visibility and Monitoring?
Network observability can provide significant value in the form of reduced Mean Time to Resolution, more productive employees, and more time for the IT team to spend on other projects.Tech Bytes: Solving WAN Problems With Singtel Solutions (Sponsored)
