Single-bit errors in these bytes can be corrected and multiple-bit errors can be detected by this value. The key differentiation between a cell and an IP packet is that a cell is always fixed length. This may not seem such a big deal, but it is huge. In fact, it is a complete departure from the way things used to be done with pre-ATM protocols. In TCP/IP networking, IP is responsible for fragmentation (at routers) and reassembly (at hosts) of data, which takes place on a hop-by-hop basis. 5 Kbytes).

For each packet heard, keep track of the packet's source MAC address and the interface from which it originated. This is referred to as the station cache. Look at the destination field in the MAC header. If this address is not found in the station cache, forward the packet to all interfaces other than the one on which the packet was received. If the destination MAC address is in the cache, forward the packet to only the interface the destination address is associated with. If the destination address is on the same bridge interface as the source address, drop the packet; otherwise, duplicate delivery of packets will result.

Currently, these hardware-specific devices are known as Application Specific Integrated Circuits (ASICs). Figure 1-4 Encapsulation through the layers of the OSI model. Page 10 What causes the software router to require more processing power than a bridge to perform adequately under the same load is that the router performs table lookup for both IP address (the routing table) and MAC address [the Address Resolution Protocol (ARP) table] before a packet can be forwarded through an interface. Of course, in most live networks, a routing protocol of some kind is deployed, such as RIP or OSPF, which adds to the processing burden of the router.
