What networking challenges does for the Open Ethernet address and how does it improve them? What would be some of the future business demands on data networks that Open Ethernet would satisfy? Solution 1)Answer: challenges: If a networked Layer 2 device such as a bridge or LAN switch could contain a list of all known MAC addresses, then the network node could function in much the same way as a router, forwarding frames instead of packets hop-by-hop through the network from source LAN to destination LAN. However, the MAC address is much larger than the IPv4 address currently used on the Internet backbone (48 bits compared to the 32 bits of IPv4). This poses problems. Also, because the MAC address has no “network organization” like the IPv4 or IPv6 address, an Layer 2 network node must potentially store every conceivable MAC address in memory for next-hop table lookups. Instead of tables of about 125,000 entries, every Layer 2 network node would have to store millions of entries. Improvement: Wireless access points often use MAC addresses for access control. They only allow access for known devices (MAC address is unique and identifies devices) with the correct passphrase. DHCP servers use the MAC address to identify devices and give some devices fixed IP addresses. uses: Hotels, restaurants and bars are increasingly being pushed to offer ubiquitous and free WiFi – in hotel rooms and also in all common areas. Travelers and patrons, now used to having access anywhere, at any time for their multiple smart devices, demand connectivity and choose where to patronize accordingly. Ethernet-based Dedicated Internet Access can provide this feature both costeffectively and reliably. Moreover, multi-site hotel and restaurant chains operating in today’s fastpaced online business environment can upgrade and consolidate services onto a single network that supports voice, data and video traffic alike..
