What are packets and routers? What is an IP address? Describe the advantages of private and public IP addresses.© BrainMass Inc. brainmass.com October 25, 2018, 8:33 am ad1c9bdddf
A packet is one unit of binary data capable of being routed through a computer network. To improve communication performance and reliability, each message sent between two network devices is often subdivided into packets by the underlying hardware and software (About.com, 2013).
A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network. When any file (e-mail message, HTML file, Graphics Interchange Format file, Uniform Resource Locator request, and so forth) is sent from one place to another on the Internet, the Transmission Control Protocol (TCP) layer of TCP/IP divides the file into "chunks" of an efficient size for routing. Each of these packets is separately numbered and includes the Internet address of the destination. The individual packets for a given file may travel different routes through the Internet. When they have all arrived, they are reassembled into the original file (by the TCP layer at the receiving end) (Rouse, 2007).
A Router is a device ...
The solution discusses packets, routers and IP addresses. In terms of security, private IP address is favored over public IP address. However, Public IP addresses is favored in terms of commercial benefits.
Need some help in securing a VPN solution using IPSec
VaryNet Inc. wants to create four separate offices across the globe. They want to be able to connect these offices over the Internet, and they want to make sure that each network is available to each other, i.e., they want the routing information of all four networks to be available at each site, so that any employee can go to any site, and work from them, and they are worried about passing traffic over the Internet. What would you offer as a network suggestion?
Being this is from scratch; no systems in place, It has to be a VPN environment. Thats the simple part. IPSec is becoming more and more accepted but it is my understanding, through my reading, that IPSec will not be practical untill IP6 is fully implemented globally. Im looking for someone to tell me if I am on track. I'm also lost on the routing between offices part. With true VPN access to basically an Intranet Environment at each office; there really shouldnt be any need for "Routing" per se unless I am missing something. I only have 2 days for this project before I head back to the field, so I just need some guidence.View Full Posting Details
