Netware

Physical and Data-Link layers use existing standards
IPX - Internetwork Packet Exchange (Connectionless)
SPX - Sequence Packet Exchange - Transport Layer
SAP - Service Advertisement Protocol (Servers and Routers)
Netware OSI Model

Addressing

IPX Network Address
  • Unique across whole Netware environment (No subnets)
  • 80 Bits - Hexadecimal - 20 digits
Network Number (32 bits - usually IPv4 network address) . Network ID (48 bits - usually MAC Address)
192.168.2.0 (groups of 4 binary units) = C0A80200
C0A80200.0000.0C92.88FB

Routing

RIP, NLSP, or EIGRP

RIP

RIP enabled by default
Metric is TICK (Delay), hop count used as tie break
No compatible with IP RIP.
Max 16 hops.
