STP

STP = 802.1d
PVST = Cisco proprietary Per-Vlan STP
Rapid-STP = RSTP = 802.1w
Rapid-PVST = Cisco per-vlan RSTP
Rapid Per-VLAN Spanning Tree (R-PVST) 
IEEE 802.1D-2004 now incorporates RSTP and obsoletes STP
Cisco latest: Rapid-PVST+
Multiple Spanning Tree (MST) = 802.1s

VoIP

CallVoip biedt een veel ruimere dienstverlening en garandeert 
bovendien dat alle huidige ISDN-nummers overgenomen kunnen worden. 
Ook is het met behulp van een zogeheten Fritz!Box 7270 mogelijk 
bestaande ISDN-apparatuur aan te sluiten. De Fritz!Box is een 
router, mini-telefooncentrale, DECT-basisstation en draadloos 
toegangspunt (WiFi) in één.
Kies voor de FRITZ!Box 7170 of FRITZ!Box 7270 en u kunt uw 
ISDN-apparatuur gewoon blijven gebruiken, zónder dat u nog de 
ISDN-dienst afneemt. De FRITZ! praat ISDN met uw apparatuur, 
en u belt voordelig via VoIP uit.

Load-Balancing

QoS

The traffic engineering term quality of service (QoS) refers to resource reservation control mechanisms: the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. In the absence of network congestion, QoS mechanisms are not required.

NTP

NOTE: 
- ntpdate will update the clock at once after consulting the time source
  BUT: it will not skew/slew and that can upset running programs
  SO: only run it at startup
- ntpd will update the clock in small steps and keep it synchronised
  BUT: it will panic exit when encountered with more the 1000s difference
  SO: when ntpd is not running, run ntpdate and restart: ntpd

Fibre Channel

  • Fibre Channel (ANSI standard)
  • Fibre Channel Protocol (FCP) is a transport protocol (similar to TCP over IP) which transports SCSI commands over FC networks.
  • SAN = Storage Area Network or Storage networking
  • iSCSI = SCSI relay over IP
  • iFCP = FC relay over IP (no tunneling like FCoIP which needs FC cabling)

FCIP

FCoE

  • FCoE = Fibre Channel over Ethernet = encapsulation of FC frames over Ethernet
  • IBM RedPaper “An Introduction to Fibre Channel over Ethernet, and Fibre Channel over Convergence Enhanced Ethernet”
    http://www.redbooks.ibm.com/Fredpapers/pdfs/redp4493.pdf
    • IEEE 802.1Qbb (priority-based flow control) is een enhancement van het zogenaamde IEEE802.3X Pause Packet
    • IEEE 802.1Qaz (enhanced transmission selection) zorgt voor een toekenning van bandbreedte voor gespecificeerde applicaties
    • IEEE802.1Qau wordt toegepast voor notificatie van congestie
    • IEEE 802.1 DCBX (data center bridging exchange protocol) is gebaseerd op het standaard link layer discovery protocol (LLDP) en zorgt voor het automatisch instellen van de verbinding op basis van uitwisseling van parameters tussen converged enhanced ethernet (CEE) hosts en switches.
