How “Dynamic Pathing” Provides Benefits Not Achievable with Static Physical Device Chains

In our last blog post we explored how Service Function Chaining (SFC) differs from the traditional model of creating a sequence of functions. Another key difference is that the path through the SFC can be “dynamic”, as noted in this Intel white paper. The dynamic qualities of the...

How Automatic Scaling and Optimal Pathing Benefits Service Function Chaining

One of the obvious questions relating to Service Function Chaining (SFC) is how does it differ from the traditional model of creating a sequence of functions (FW/IPS, ADC, vWAN, Router), whether in specialized hardware or dedicated VMs, and passing traffic between those functions...

OPNET Modeler (currently, Riverbed Modeler)

Network Simulation Wikipedia describes network simulation as “a technique where a program models the behavior of a network by calculating the interaction between the different network entities (hosts/routers, data links, packets, etc.) using mathematical formulas.” But beyond the...

Looking at OpenWrt as an option for Enterprise Routers

With the Internet of Things gaining in popularity, embedded devices are getting more attention. An operating system that’s also getting its share of attention is OpenWrt, an OS that’s primarily for embedded networking devices. It’s based on the Linux kernel and primarily used on...
