Core Linux Live Router

2.2 Core

According to Saxena 2010, Core OS Layer contains all the middlewareOS service domains and the hardware adaptation services. It includes the Linux kernel and all the middleware needed to define hardware and usage model independent API for building both native applications and web run time applications. According to official apple, the core OS layer contains the low-level features that most other technologies are built upon. Even if you do not use these technologies directly in your applications, they are most likely being used by other frameworks. And in situations where you need to explicitly deal with security or communicating with an external hardware accessory, you do so using the frameworks in this layer,

2.3 Linux Live

According to Tomas 2011, Linux Live is a set of shell scripts allows you to create your own Live Linux from an already installed Linux Distribution. The Live system you create will be bootable from CD_ROM or a disk device, for example USB Flash Drive, USB Pen Drive, Camera connected to USB port, and so on. People use Linux Live scripts to boot Linux from iPod as well. Interesting feature of Linux Live Script: 1. Persistent changes 2. Adding modules on the fly 3. installable system to disk.

2.4 Router

Based on Dede 2010:25, router has ability to forward packet IP from one network to other networks that possible to have many routes among the routers. Router also can be used to connect some LAN, so the traffic from LAN can be handled. If two or more LAN connected to the router, every LAN consider as different sub network. According to iwan 2009:58, a router has routing function. It means, router can know the route information called packet will be forwarded, whether the packet for host in same network or for host in different networks. If the packet is for a host in different networks, the router will forward to that network. If the packet is for a host in the same network, the router will block the packet to go out, so the packets will not “flood” to other networks. According to Fathul 2001:240, router is a hardware that route data from LAN to cellular. Router is used to guarantee that only machine who has authority that can transmit data to LAN. Besides that, router is also used to check the error, save statistic the usage of network, and support firewall.
