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

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 𝑀𝑃𝐿) that a packet can

exists in a network

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

retransmit its unacknowledged messages;

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

wait before sending acknowledgment.

∆𝑡 = 𝑀𝑃𝐿 + 𝑅 + 𝐴 All connections exist all the time

Decoupling of port allocation from synchronization

After period of 2-3 ∆𝑡 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)

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
