TCP/IP problems area (2)?

• ????? 80' ST-II RC 1190 streaming protocol put
  pressure on Best Effort quality of service,
  solution extra capacity
• No security mechanisms , myth
• No support for resiliency , myth
• IMP ID addressing kept in Ipv6
• Not like CYCLADES, DECNET, XNS, OSI addressing

TCP/IP problems area (3)?

• Backbone routes smartgrid peril
• IETF LISP, Loc/ID separation protocol ignored
  IPv7 (1992)?
• TCP/IP split 1978 concept of layers from Dijkstra
  THE Operating system 1970
• TCP, UDP repeat policy/mechanism
• TCP numbers acks bytes not packets
• OSI Layer OK in 1985 (3subnetwork independant,
  dependent, convergence)?

TCP/IP problems area (4)?

• Internetwork only lt 1983 Flag Day , IP over NCP
• NAT break (only broken architectures)?
• (role 1 address, role 2 security)?
• IP address port number connection ID

CLEAN-SLATE Recursive InterNetwork
Architecture (RINA)

• John Day reporter for OSI reference model
• Upper layers 5-6-7 one layer (1983)?
• OSI programme collapse, implementers used
  different protocol machines
• TCP/IP simple layer model wins
• Practical IP community
• BUT fixed protocol stacks problem also
• Why? Protocol functions alternate up the stack
  (error cntl, cntrl DTP DTCP), same in X.25
  L2,3 same in IP, in TCP in wireless, in
  applications.
