Chapter 3 Self Study Question 52 terms by Zeetzo STUDY Flashcards Learn Speller Test PLAY Scatter Gravity Scores Scores Info Info Original Alphabetical At what layer of the OSImodel would a TCP or UDPheader be added to apayload? Layer 4 A globally unique number that identifies an autonomous system. ASNs work similarly to IP addresses that identify individual nodes on a network. Each ASN now consists of 32 bits instead of 16 bits, and they are assigned by IANA. autonomous system number The largest IP packet size in bytes allowable by routers in a path without fragmentation and excluding the frame size. MTU (maximum transmission unit) A repeated trial message transmitted by the tracert and traceroute utilities to trigger routers along a route to return specific information about the route. probe A router that connects an autonomous system with an outside network—for example, the router that interior router List List Search Create Log in Sign up
connects a business to its ISP. Properties of a route used by routing protocols to determine the best path to a destination when various paths are available. Routing metrics may be calculated using any of several variables, including hop count, bandwidth, delay, MTU, cost, and reliability. routing metric The router on a network that accepts all unroutable messages from other routers. gateway of last resort The delay between the transmission of a signal and its receipt. latency A process whereby routers learn about all of the devices on their networks. On IPv4 networks, this process is managed by ARP with help from ICMP. On IPv6 networks, NDP (Neighbor Discovery Protocol) automatically detects neighboring devices and automatically adjusts when nodes fail or are removed from the network. neighbor discovery A router that directs data between networks within the same autonomous system. gateway router A number indicating a protocol's reliability, with lower values being given higher priority. This assignment can be changed by a network administrator when one protocol should take precedence over a previously higher-rated protocol on a network.
