<a name="l1"></a><span class=c0F>Zeal Networking Stack Notes</span><span class=cF0>
<a name="l2"></a>
<a name="l3"></a>Departures from Shrine:
<a name="l4"></a>
<a name="l5"></a> ARP Cache is Hashtable. Keys are U32 ip addresses converted to &quot;%X&quot; string.
<a name="l6"></a>
<a name="l7"></a> DNS Cache is Hashtable. Keys are U8 *hostname.
<a name="l8"></a>
<a name="l9"></a> NetFIFO is NetQueue. If problems arise, maybe set a #define max
<a name="l10"></a> for the length of the Queue.
<a name="l11"></a>
<a name="l12"></a> Not defining ntohl and friends. Using Endian functions.
<a name="l13"></a>
<a name="l14"></a> Many file global vars have been condensed into global classes.
<a name="l15"></a>
<a name="l16"></a> Sockets are a non-standard finite state machine.
<a name="l17"></a> Protocols extend these to create protocol-specific sockets.
<a name="l18"></a>
<a name="l19"></a>Stack progress: (# done, ~ WIP, . N/A)
<a name="l20"></a>
<a name="l21"></a> # PCNet-II Driver
<a name="l22"></a> . Other Network Card Drivers? See </span><a href="https://zeal-operating-system.github.io/ZealOS/Home/Roadmap.DD.html#l10"><span class=cF4>Roadmap</span></a><span class=cF0>.
<a name="l23"></a>
<a name="l24"></a> # NetQueue
<a name="l25"></a>
<a name="l26"></a> # Ethernet
<a name="l27"></a> - double check.
<a name="l28"></a>
<a name="l29"></a> # ARP (Address Resolution Protocol)
<a name="l30"></a> - double check.
<a name="l31"></a>
<a name="l32"></a> # Sockets
<a name="l33"></a> - Implemented a Finite State Machine
<a name="l34"></a> through Socket function calls.
<a name="l35"></a> Sockets themselves do nothing,
<a name="l36"></a> all calls simply do/don't alter
<a name="l37"></a> socket state. Protocols will
<a name="l38"></a> need to detect socket states
<a name="l39"></a> and respond appropriately.
<a name="l40"></a> - keep eyes on verifying socket logic sanity.
<a name="l41"></a>
<a name="l42"></a> # IPV4 (Internet Protocol Version 4)
<a name="l43"></a> - double check, some TODOs.
<a name="l44"></a>
<a name="l45"></a> ~ ICMP (Internet Control Message Protocol)
<a name="l46"></a> - needs ICMPSendRequest implemented.
<a name="l47"></a>
<a name="l48"></a> ~ TCP (Transmission Control Protocol)
<a name="l49"></a> - needs much testing, still many bugs/oddities.
<a name="l50"></a> - needs reviewing RFC for better compliance.
<a name="l51"></a>
<a name="l52"></a> # UDP (User Datagram Protocol)
<a name="l53"></a> - double check, some TODOs.
<a name="l54"></a>
<a name="l55"></a> ~ DNS (Domain Name System)
<a name="l56"></a> - needs clarifying/rewriting in certain methods.
<a name="l57"></a>
<a name="l58"></a> ~ DHCP (Dynamic Host Configuration Protocol)
<a name="l59"></a> - needs clarifying/rewriting in certain methods.
<a name="l60"></a>
<a name="l61"></a> # NetHandler
<a name="l62"></a> - Uses a switch case with packet ethertype,
<a name="l63"></a> then directly calls the appropriate handler.
<a name="l64"></a>
<a name="l65"></a> - IPV4Handler was moved to NetHandler file.
