Data-Centric Network (Unit 4)

Layer 2 Networking








STP - Purpose

  • Redundancy in layer 2 switches
  • Loop intervention

  • Better than redundant switch links

STP - Loop free

  1. Elect root bridge
  2. Elect root ports

  3. Elected designated ports

  4. Elect alternate ports

Ethernet Standards

  • MSTI
  • IEEE 802.3ba
    • 40GB Ethernet VS 100GB Ethernet

  • EVB
    • TOR
    • EOR
  • VEB

  • VEPA
  • TRILL
  • FCOE VS FCIP

  Data-Centric Network (Unit 3) Server Architecture Network Attachment - Interface for the communication between server and client via the network. Network Interface Cards - Provide connectivity between hosts. DMA - Transfers data without involving the system processor. Interrupt coalescing - Reduces the number of interrupts hence reducing delay. Jumbo frames - Support bigger ethernet frames. Server Multihoming Fault tolerance - Only one port is active which upon failure would keep it on standby and the other port take up the load. Load balancing - One port receives all the traffic. Link aggregation - A bunch of ports looks like a single link with equivalent bandwidth. PCI & PCI-X Buses - Bandwidth allocation of 533 MBPS & 1.066 GBPS. Client Server Packet Processing - How the OS handles the processing of IP packets. User mode VS Kernel mode - Interrupt handling & system services etc. Ethernet Driver Server TCP/IP Sockets Listen - Length of  receive queue of...

Calculate DOF. State decision rule. Calculate the test statistic. State result. State conclusion. Two-way ANOVA - At least 2 factors that have dependent or independent levels. Three-way ANOVA Diagrammatic understanding. Assumptions of ANOVA Normality of sampling distribution of means I ndependent of errors Absence of outliers. Homogeneity of variances. Hypothesis of ANOVA H0 is the initial condition. H1 is the secondary condition. NOTE *Sums have been omitted in this article, this can be used for reference.

Basic Syntax & First Code Build

Basic Syntax & First Code Build Here is the syntax list for beginners to know how to start coding. Header Files #include<bits/stdc++.h> Function Syntax cin>> cout<< endl Data Type int string char double float Structure #include<bits/stdc++.h> using namespace std ; int  main () { //**ALL MAGIC HERE** --> Commented using '//' } The header file given above is usually enough for any code since it is a combined file of almost all C++ header files . The cin must have >> and cout must have  <<   and all code usually ends with a " ; " int accepts integer numbers between  -2,147,483,648 to 2,147,483,647 . string accepts inputs like agh3487bkk. You can guess and then check what the other data types do . With this knowledge, try and see if you can generate this output, if you just got started in C++, then see the code and get the idea and then try it on your own. #include<bits/stdc++.h> using namespace std ...
