C# 클래스 Ipop.IpopNode

Converts from a.b.c.d to the number of 1s in a.b.c.d (CIDR notation).

This method handles all incoming packets into the IpopNode, both abroad and local. This is done to reduce unnecessary extra classes and circular dependencies. This method probably shouldn't be called directly.

This method handles IPPackets that come from Brunet, i.e., abroad.

Creates an IpopNode given a NodeConfig and an IpopConfig. Also sets up the Information, Ethernet device, and subscribes to Brunet for IP Packets

Starts the execution of the IpopNode, this passes the caller to execute the Brunet.Connect to eventually become Brunet.AnnounceThread.

The request on the IP allocation space (DHT) has returned. So we're done with the server.

Static addresses are handled nearly identically to dynamic, so we use one shared method to pull a dhcp server from the list of dhcp servers. We only want one request per Ethernet / IP at a time.

We need to get the DHCPConfig as soon as possible so that we can allocate static addresses, this method helps us do that.

Used to retrieve an instance of the DhcpServer associated with this type of node.

Parses Arp Packets and writes to the Ethernet the translation.

IpopRouter makes nodes think they are in the same Layer 2 network so that two nodes in the same network can communicate directly with each other. IpopRouter masquerades for those that are not local.

This method is called by HandleIPOut if the destination address is the broadcast address. If you want Broadcast, implement this method, output will most likely be sent via the SendIP() method in the IpopNode base class.

This is used to process a dhcp packet on the node side, that includes placing data such as the local Brunet Address, Ipop Namespace, and other optional parameters in our request to the dhcp server. When receiving the results, if it is successful, the results are written to the TAP device.

If a request is sent to address a.b.c.255 with the dns port (53), this method will be called by HandleIPOut. If you want Dns, implement this method, responses should be written directly to the tap interface using Ethernet.Send()

This method handles IPPackets that come from the TAP Device, i.e., local system.

Currently this supports HandleMulticast (ip[0] >= 244 && ip[0]<=239), HandleDns (dport = 53 and ip[3] == 1), dhcp (sport 68 and dport 67.

This method is called by HandleIPOut if the destination address is within the multicast address range. If you want Multicast, implement this method, output will most likely be sent via the SendIP() method in the IpopNode base class.

Let's see if we can route for an IP. Default is do nothing!

Is this our IP? Are we routing for it?

Sends the IP Packet to the specified target address.

This sends an Icmp Request to the specified address, we want him to respond to us, so we can guarantee that by pretending to be the Server (i.e. x.y.z.1). We'll get a response in our main thread.

Called when an ethernet address has had its IP address changed or set for the first time.

Writes an IPPacket as is to the TAP device.
