Vi ställde oss då frågan varför har ingen övergång skett trots dessa fördelar. Frågeställning: Var i övergången mellan IPv4 och IPv6 står vi idag? Varför har inte övergången mellan IPv4 och IPv6 redan skett? Vilka är de största anledningarna och vilka fler möjliga finns det? Slutsats: Arbetet visar att tiden för en övergång ännu inte är inne.

Små- och medelstora företags uppdateringsarbete av hemsidor

Många små- och medelstora företag har idag en hemsida. För att en hemsida skall vara ett effektivt kommunikationsmedium med kunder krävs dock att den är uppdaterad. Vi anser att många företag ej förutser vilka resurser som krävs för att hålla sidan uppdaterad. Vi vill därför kartlägga vilka problem företag i dagsläget upplever att de har med sitt uppdateringsarbete. Vi vill därefter se om det finns en möjlig lösning i verktyget Smelink WEB ifrån Smelink AB, som säger sig underlätta webbnärvaron för denna typ av företag. För att undersöka ovanstående frågeställning har vi valt att gå ut med en enkätundersökning rörande hur uppdateringsarbetet går till i två grupper av företag. Den ena företagsgruppen använder sig utav Smelinks verktyg och i den andra företagsgruppen vet vi ej hur uppdateringsarbetet går till. Då vi sammanställt resultatet kunde vi konstatera att det ej fanns några omfattande problem rörande uppdateringsarbetet hos de företag som vi undersökt.

TCP/IP i taktiska ad hoc-nät

TCP (Transmission Control Protocol) is a transport protocol designed for the wired Internet. In wireless networks packet losses occur more frequently due to the unreliability of the physical link. The main problem is that TCP treats all losses as congestion, which leads to a lower throughput. Ad hoc networks are multihop wireless networks of mobile nodes, where each node can allow other packets to pass through it. Topology changes often occur and may lead to packet losses and delays, which TCP misinterprets as congestion.
