Note: You should read about Content Addressable Memory (CAM) before reading this post. Today’s networking hardware operates a Layer 2, Layer 3 and Layer 4 of the OSI model. The device might switch Ethernet frames, route IP packets and implement filters based on the TCP segments. A MAC Address is always an exact match and […]
Binary CAM performs a binary lookup ands returns either a 1 or 0.
Content-addressable memory (CAM) is silicon chip architecture that is purpose-built for extremely fast but very specific type of memory lookups.
The terms routing, switching, forwarding and bridging have different meanings that have changed over time.
Question : Is there always a feasible successor in EIGRP ?
This article provide a practical and workable definition of “What Is a Network Service ?”
The following command line will use the Text to Speech converter in *nix to say the word “pingtastic” every time a successful icmp response message is received using the ping command.
A link in a network is determined by two factors, bandwidth and speed. These are usually the same but not always. Definition: Speed is bit rate of the circuit while bandwidth is the amount of “speed” available for use. As an example, a 500 Megabit Ethernet MPLS service which uses a 1 Gigabit Ethernet connection to […]
When installing Fibre Optic cable care must be taken to ensure that cable is not bent beyond a certain radius. Most people believe this is to prevent breaking of the fibre core but there is a worse scenario.
Containers virtualize at the operating system level, Hypervisors virtualize at the hardware level. Hypervisors abstract the operating system from hardware, containers abstract the application from the operation system. Hypervisors consumes storage space for each instance. Containers use a single storage space plus smaller deltas for each layer and thus are much more efficient. Containers can boot and be […]
