The Final Stretch Flashcards
RIP
Routing Information Protocol. Distance-vector. Uses hop count and limits hops to prevent looping.
EIGRP
Enhanced Interior Gateway Routing Protocol. Distance-vector. Routers on EIGRP send hello packets intermittently to verify functionality and work together to determine the best path.
OSPF
Open Shortest Path First. Link-state. Routers communicate with each other about other routers to determine the shortest path.
BGP
Border Gateway Protocol. Hybrid. Enables the internet to exchange routing information between Autonomous Systems.
Distributed Switching
A virtual switch that acts as a single switch for all hosts in a virtual environment
VLSM
Variable Length Subnet Mask. Works closely with CIDR to break up subnets for more flexibly in IPv4 networking.
IPAM
IP Address Management. The administration of DHCP and DNS. It is a means of planning, tracking, and managing the IP address space used in a network.
APC
Angled Physical Contact fiber connection
UPC
Ultra Physical Contact fiber connection
MTRJ
Small Form Factor Duplex Connector. Holds two fibers at the same time in a small body.
Media Converter
Converts media (I.e, Fiber optics to Ethernet connections)
RADIUS
Remote Authentication Dial-in User Service. Provides AAA to users
NAS vs SAN
NAS is a single device storing data for multiple hosts. SAN is a network of devices providing various storage services.
Fibre Channel
A high-speed data transfer protocol for SAN
iSCSI
IP-based standard for transferring data that supports host access by carrying SCSI commands over the network.
Infiniband
Computer networking communications standard with very high throughput and low latency.
ISDN
Integrated Services Digital Network. A set of communication standards that used digital transmissions to make phone calls, video calls, transmit data, and other network services of PSTN.
T1/T3
T1 has 24 channels. 1.544 Mbps; T3 has 28 T1 lines (672 channels) and 44.7 Mbps
E1/E3
E1 has 32 channels. 2.048 Mbps; E3 has 34.4 Mbps
OC3 – OC192
OC192 – 51.84 mbps x OC# (OC192 = 9.953 Gbps)
PRI
Primary Rate Interface. A telecommunications standard used on an ISDN network for carrying multiple DSO voice and data transmissions between the network and the user.
MPLS
Multiprotocol Label Switching. Data flow technology that increases the speed and controls the flow of by using labels instead of a routing table lookup at every stop.
