What is Vector Packet Processing (VPP)?

Vector-Packet-ProcessingVPP

The VPP platform is an extensible framework that provides out-of-the-box production quality switch/router functionality. It is the open source version of Cisco's Vector Packet Processing (VPP) technology. This a high performance, packet-processing stack that can run on commodity CPUs.  The framework allows anyone to "plug in" new graph nodes without the need to change core/kernel code.

SDN & OpenFlow

OpenFlow

Traditional networking is made up of a control plane, and data plane where the control and data planes are combined each into the network elements making up the network. This creates a limitations, because the control plane, and data plane normally resides in the individual routers and switches. Any changes in the network topology (ie: links or routing/switching devices going up/down) will have to be communicated to the other network elements. This causes a propagation delay that gets longer as the network grows.

Virtualization Machines (VM)

Virtualization-101

A VM is a tightly isolated software container that runs its own operating system and applications as if it were a physical computer. Because VMs are software, not only can you run them on any server but you can also suspend or freeze a VM and then you can

Software Defined Networking vs Traditional Networking

Software-Defined--Networking

Traditional Networking is made up of a control plane, and data plane where the control and data planes are combined each into the network elements making up the network. This creates a limitations, because the control plane, and data plane normally resides in the individual routers and switches. Any changes in the network topology (ie: links or routing/switching devices going up/down) will have to be communicated to the other network elements. This causes a propagation delay that gets longer as the network grows.  A new set of networks known as programmable networks have emerged as a solution to this problem.

OpenStack Networking

OpenStack
Cloud-based solutions are being adopted at an increasing rate by businesses for their IT driven needs. This move to cloud started with the server virtualization where a hardware server ran as a virtual machine on a hypervisor. The server hardware connects to the Network switches using Ethernet and IP to establish Network connectivity. However, as s...

Network Subnetting

billionphotos-2796585
Subnetting allows a large network block to be logically segmented into multiple smaller networks, or subnets. The use of many smaller networks allows the use of varying physical networks, such as Ethernet or Fiber Optic, which could not otherwise be combined. Additionally, the smaller subnets can improve the speed of traffic and permit easier manag...
