[Digging-Up] The Story of Router Development
How has the miracle box, the Internet infrastructure supporter, evolved?

- Routers are the primary backbone device of any network. This article answers questions such as, How did they evolve into what they are today? and What will they become in the future?
Nikkei Network digs up the story of routers from engineers who were actually involved in their development.


Prologue: Pre-Router Days

Part 1: Birth of an IP Router (to 1982)

Part 2: Path to Commercialization (to 1986)

Part 3: Evolution of Router Architecture (to 2004)

Part 4: Routers of the Future

Network Technologies in the Spotlight in 2005
Explaining the key points that sum up their essence

- Various network technologies debuted in 2004 and were put to many practical uses. Nikkei Network highlights seven such technologies that are expected to take a great leap forward in the coming year and play an important role in the network field.
This article reviews those technologies so that the reader can anticipate what is likely to happen to networks in 2005.


SoftEther: SoftEther conducts software emulation of LAN devices such as LAN switches and LAN cards, and it is used to create a virtual LAN via the Internet

GE-PON (Gigabit Ethernet-Passive Optical Network): GE-PON allows users to share a fiber optics line that has a speed of 1 Gbit per second, and it delays the timing of incoming signals

MIMO (Multi-Input Multi-Output): MIMO is the basic technology for the next-generation Wireless LAN standards and enables parallel transmissions using multiple antennas

DLNA (Digital Living Network Alliance): DLNA provides standard specifications to encourage connectivity between audio-visual devices and uses the existing technologies centered on UPnP (Universal Plug and Play)

Quarantine Network: A quarantine network isolates individual computers from a main network and checks whether or not they are infected before allowing them to connect to an in-house corporate network

SIP (Session Initiation Protocol): SIP is a protocol designed to control communication sessions by establishing and terminating them with one or more participants via a server

Transmitter Identification: This new technology identifies the real sender of e-mail by verifying the IP address of the sender against the data registered in the Domain Name System (DNS)


KEY POINTS OF HOT TECHNOLOGIES

Learning about Skype, Freeware for Free PC-based IP Telephony
- How does it determine the destination of a call? How is it able to go through NAPT (Network Address Port Translation)?


STRATEGY FOR ENHANCING WINDOWS-BASED NETWORKS

Using SSH (Secure Shell) for Secure Remote Access
- SSH is a protocol for encrypting network communication, and it allows services based on TCP to go through
