And the PON is a more perfect technology in access network. The new optical access network binds the ETHERNET technology in data link layer and PON technology in physical layer to form a more broad band and less cost and more strong service process ability ,which is EPON. The EPON omits the complexity of IP mapping to ATM. It is the hottest technology in recent years.With development of IP broadband router technology and the discuss of IP network, the MAN has rapidly been the load-carrying network of future telecommunication services. The router with large capacity, High bandwidth, High process large capacity will be the load-carrying network core. The IP MAN and Layer2 broadband access network structure with clear of matter and logic is essential. The structure need distributed structure hardware Component Architecture and line-rate hardware switch to meet the requirement of MAN.Over the years, network-security technology and deployments have had to adapt to constant changes in the surrounding security foundations. To date, this has commonly resulted in firewall and other technologies being deployed on the network's border and in front of core resources. This has successfully stopped many external threats and served trusted internal users. However, the past few years have introduced several environmental factors which invalidate the inside vers...
