Future Work

Proposed Changes To Make The Code Scalable

Modifications in DHCP Server Configuration

• The current server configuration provides IP addresses to incoming clients from a single address pool.
• This pool consists of IP addresses from only the server's subnet.
• The InstallDhcpServer() function adds all the attributes of the server including its own IP address and launches the start application.
• This should be split into 2 separate functions :

  • ApplicationContainer InstallDhcpServer(Ptr<NetDevice> netDevice, Ipv4Address serverAddr, Ipv4Mask Mask)

    This function will allocate the server IP address to the Ptr argument passed, install a default traffic control configuration, creates a DHCP server app and returns that pointer.

  • void AddAddressPool(ApplicationContainer dhcpServerApp, Ipv4Address minAddr, Ipv4Address maxAddr, Ipv4Address gateway)

    It will add the IP addresses in the given range i.e. within minAddr and maxAddr, as a pair along with given gateway to m_availableAddresses (a map consisting of gateway and IP addresses allocatable a subnet).

Modification in DHCP Relay Agent Configuration

• Our current implementation supports only two subnets - one having the DHCP server and the other for incoming clients.

• We have written two functions to initialize client and server side :

  • Ipv4InterfaceContainer InstallFixedAddress (Ptr<NetDevice> netDevice, Ipv4Address addr, Ipv4Mask mask)
  • ApplicationContainer InstallDhcpRelay (Ptr<NetDevice> netDevice, Ipv4Address relayAddr, Ipv4Mask subMask, Ipv4Address dhcps)
