RECURSIVE INTERNETWORK ARCHITECTURE

 One generic layer (called DIF, Distributed IPC Facilty) that limits scope 1) Data transfer with soft-state timer-based synchronization 2) Complete addressing and naming scheme 3) Split between mechanism (fixed) and policy (flexible) 4) Single generic application protocol

HISTORY

 In 2007 book Patterns in Network Architecture: A Return to Fundamentals by John Day

1) SOFT-STATE TRANSPORT PROTOCOL

 Hard-state = explicit synchronization prior to communication using special messages (i.e., TCP flags and 3-way handshake)  Data Transfer Protocol (DTP) based on Richard Wattson’s transport protocol Delta-t from 1984

 Proves that hard-state is unnecessary IFF

Maximum Packet Lifetime denotes upper bound time (value 𝑁𝑄𝑀) that a packet can

exists in a network

Retransmission-timer specifies maximum period (value 𝑆) that a sender is willing to

retransmit its unacknowledged messages;

Acknowledgment-timer defines maximum delay (value 𝐵) that the receiver of data can

wait before sending acknowledgment.

∆𝑢 = 𝑁𝑄𝑀 + 𝑆 + 𝐵

 All connections exist all the time

Decoupling of port allocation from synchronization After period of 2-3 ∆𝑢 of no traffic, all synchronization state should be discarded, which effectively resets the connection

 Both reliable and unreliable transfer based on employment of sequence numbers

2) COMPLETE ADDRESSING

 Logical vs. Physical addresses  Variable addresses  Reflects scope (size) and usage (flat vs. hierarchical)

Application Namespace Node Namespace PoA Namespace MAC address IP address Port number Route Path

Application Namespace Node Namespace PoA Namespace Route Path Directory

src CEP-id dst CEP-id

Ports with port-ids EFCPIs with CEP-ids Connection-id Structured IPCP address

src CEP-id dst CEP-id QoS-id

Port allocation State synchronization

Connection Flow N-PDU has

3) MECHANISM VS. POLICY

 i.e., error-checking (fixed) employing CRC (flexible)  Programmable behavior using well-defined APIs

State Vector Tightly-bound DTP Loosely-bound DTCP

EFCP instance

data traffic control traffic State Vector Relaying & Multiplexing Task RIB Daemon Flow Allocator Resource Allocator Common Distributed Application Protocol Delimiting Data Transfer SDU Protection RIB Flow Control Error Control

a) Data Transfer c) Management

Time and functional complexity increases

b) Data Transfer Control

4) CDAP

 Common Distributed Application Protocol (CDAP)

 All application protocols are stateless, the state is in the application  DTP modify state internal to the protocol and CDAP modify state external to the protocol

CDAP encapsulated into DTP

 Request-response scheme with feedback

 Primitive operations governing objects (i.e., files)

 Read / Write  Create / Delete  Start / Stop

 Subcomponents

 CACE – connection establishment  Auth – authentication  CDAppP – protocol operation 6 messages × 2 directions = 12 message types
