2 Overview Network node architecture refactoring Cross-layer communication and optimization Mobility refactoring
3 Real World Network Node Architecture Real world applications often use different kind of sockets and protocols simultaneously Application Kernel Socket API Transport Layer TCP UDP Network Layer IPv4 IPv6 Link Layer Ethernet PPP VLAN
4 Current Network Node Architecture 1 Nodes currently have separate submodule vectors for different kinds of applications What if an application wants to use TCP and UDP simultaneously? tcpapp[] tcp App[] pingapp[] tunapp[] ppp[] wlan[] tun[]
5 Current Network Node Architecture 2 TUN application are currently connected to TUN interfaces only TUN applications are useless without being connected to other protocols Should we connect them to TCP, UDP, IPv4, or all of them? tcpapp[] App[] pingapp[] tunapp[]? tcp ppp[] wlan[] tun[]
6 Current Network Node Architecture 3 Dual network stack needs extra dispatch mechanism towards network protocols Where should the dispatch mechanism be? In general, protocols of adjacent OSI layers should be in many-tomany relationship tcpapp[] tcp App[] pingapp[] tunapp[]? ipv6 ppp[] wlan[] tun[]
7 TCP Applications Limitation: TCP applications exclusively and directly connect to TCP tcpapp[] tcp Dispatch from TCP towards applications is built into TCP Dispatch from IPv4 towards TCP is built into IPv4 App[] pingapp[] tunapp[] ppp[] wlan[] tun[]
8 UDP Application Limitations: UDP applications exclusively and directly connect to UDP tcpapp[] tcp Dispatch from UDP towards applications is built into UDP Dispatch from IPv4 towards UDP is built into IPv4 App[] pingapp[] tunapp[] ppp[] wlan[] tun[]
9 Ping Application Network layers currently have separate gates for ping applications (pingin, pingout) tcpapp[] tcp IPv4 needs to do special ICMP packet handling to reach ping applications App[] pingapp[] tunapp[] ppp[] wlan[] tun[]
10 New Network Node Architecture app[] Added separate packet s between OSI layers Eliminated dispatch mechanisms from individual protocols tcp ipv6 ppp[] wlan[] tun[]
11 Protocol Registration Mechanism app[] Protocols have to register themselves in the (protocolid, gate) tcp registers ipv6 ppp[] wlan[] tun[]
12 Interface Registration Mechanism app[] Interfaces also have to register themselves in the (interfaceid, gate) tcp ipv6 registers ppp[] wlan[] tun[]
13 Simpler Network Node Architectures Dispatchers are optional app app[] Modules can still be organized in other ways app[] eth eth
14 IPv4 Network Layer Architecture IPv4 network layer also uses a internally ARP and IP don't exchange packets, thus no connection between them igmp icmp arp ip
15 TCP Application app[] TCP application still uses a TCPSocket to send and receive packets Dispatcher learns where sockets are, based on socket open and close commands tcp ipv6 ppp[] wlan[] tun[]
16 UDP Application app[] UDP application still uses a UDPSocket to send and receive packets Dispatcher routes packets based on the destination protocol Destination protocol is determined from control info and packet class tcp ipv6 ppp[] wlan[] tun[]
17 Ping Application app[] Ping application uses a raw IPv4Socket to send and receive ICMP echo packets There's no special network layer gate for ping applications tcp ipv6 ppp[] wlan[] tun[]
18 Ethernet Application app[] Ethernet applications can directly communicate using ethernet sockets tcp ipv6 ppp[] wlan[] tun[]
19 MANET Routing Application app[] MANET routers now share the same network node architecture Routing application can be replaced from INI file Routing applications can still use all kinds of sockets routing[] tcp ipv6 ppp[] wlan[] tun[]
20 Tunnel Application app[] Tunnel application simultaneously opens a TUN device and a raw IPv4Socket tcp ipv6 ppp[] wlan[] tun[]
21 Tunnel Application 1 app[] Node receives packet from network tcp ipv6 ppp[] wlan[] tun[]
22 Tunnel Application 2 app[] Node receives packet from network IPv4 forwards packet to TUN interface tcp ipv6 ppp[] wlan[] tun[]
23 Tunnel Application 3 app[] Node receives packet from network IPv4 forwards packet to TUN interface tcp Application receives packet from TUN interface ipv6 ppp[] wlan[] tun[]
24 Tunnel Application 4 app[] Node receives packet from network IPv4 forwards packet to TUN interface tcp Application receives packet from TUN interface Application sends packet inside another IPv4 packet ipv6 ppp[] wlan[] tun[]

26 Standard Host 2
27 Overview Network node architecture refactoring Cross-layer communication and optimization Mobility refactoring
28 Cross-layer design Application Layer Quality of service parameters Transport Layer Link quality indication Network Layer Resource optimization parameters Link Layer Physical Layer Physical channel conditions
29 Current Cross-Layer Communication Applications send UDP packets on a specific interface by setting the interfaceid in UDPControlInfo Currently applications cannot even specify type of service parameter to control the quality of service functionality
30 New Cross-Layer Communication As packets go through the layers Application Layer Packets collect various request tags Transport Layer Network Layer Link Layer Physical Layer Packets collect various indication tags
31 Tag Examples QualityOfServiceRequest tos InterfaceIndication InterfaceRequest id MACAddressRequest source destination TransmissionRequest power channel id MACAddressIndication Packet source destination ReceptionIndication power channel
32 Overview Network node architecture refactoring Cross-layer communication and optimization Mobility refactoring
33 Current Mobility Models 1 There are mobility models that do static positioning There are mobility models that move nodes around How to combine these models?
34 Current Mobility Models 2 There are group mobility models with built-in differences for individual nodes How to reuse existing models for group mobility? How to model a docking ship with passengers moving around?
35 Current Mobility Models 3 Sometimes positioning and orientation are best expressed in separate mobility models (e.g. satellites) Sometimes elevation may be derived from the position on the surface of the Earth (e.g. a moving vehicle)
36 Mobility Superposition Support combining different positioning and orientation models using superposition Support start/end time (limits) for mobility models superposition positioning & orientation group initial perturbation time individual
37 Coordinate Systems Geographic coordinate system such as WGS-84 Abstract Cartesian coordinate system How to express coordinates inside buildings around a city? How to express antenna orientation of a vehicle separately?
