Network+ Chapter 8B - Routing
Blank
- Metric - a standard of measure of a degree
to which a software system or process possesses some property
- My traceroute -
a utility that records the
route (the specific gateway computers at
each hop) through the Internet between your computer and a specified destination compute
- NAT translation
table - defines the internal IP
addresses of computers on
the network
- Network Address
Transmission (NAT) - translates
the IP addresses of computers in
a local network to a single IP address
- Network
Management Software (NMS) - an
application or set of applications that lets network administrators manage a
network's independent components inside a bigger network management framework
-
next hop - an IP address entry in
a router's routing table, which specifies the next closest/most optimal router in its routing path
- Open Shortest Path First (OSPF) - a routing protocol for Internet Protocol (IP) networks. It uses
a link state routing (LSR)
algorithm and falls into the group of interior gateway protocols (IGPs),
operating within a single autonomous system (AS)
- Path vector - A routing protocol, sometimes known as a
policy routing protocol, that is used to span different autonomous systems. ...
The routing table maintains the autonomous systems that are traversed in order
to reach the destination system
- Port Address
Translation (PAT) - ach computer on LAN is translated to
the same IP address, but with a different port number assignment. PAT is also referred to as
overloading, port-level multiplexed NAT or single address NAT
- Port forwarding
- an application of network
address translation (NAT) that redirects a communication request from one
address and port number
combination to another while the packets are traversing a network gateway, such
as a router or firewall
- RIPv1 - a protocol used by routers to
exchange routing information on a network
- RIPv2 - a classless, distance vector routing
protocol as defined in
RFC 1723. Being a classless routing protocol, means, it includes the subnet mask with the network addresses in
its routing updates
- Route
redistribution - a process that
allows a network to use a routing protocol
to dynamically route traffic
based on information learned from a different routing protocol
- Router - a networking device that forwards data
packets between computer networks
- Routing
Information Protocol (RIP) - s the
process of converting a vector image into a raster image
- Routing table -
a set of rules, often viewed
in table format, that
is used to determine where data packets traveling over an Internet Protocol (IP) network will be
directed. All IP-enabled devices, including routers and switches, use routing tables
- Static
Nat (SNAT) - a network
address translation (NAT) technique that enables private network security by providing
a public Internet Protocol (IP) address to remote users/systems
- Static routes -
a form of routing that occurs when a router
uses a manually-configured routing entry,
rather than information from a dynamic routing traffic. ... Unlike dynamic routing, static routes are fixed and do not change if the network is
changed or reconfigured
- Traceroute - a utility that records the route
(the specific gateway computers at
each hop) through the Internet between your computer and a specified destination computer. It also calculates and
displays the amount of time each hop took
- Yost cable - a type of null-modem cable that is often used to
connect a computer terminal
to a router's console port. This cable is
typically flat (and has a light blue color) to help distinguish it from other
types of network cabling
