Doc & Version: TFTP Booting Extensions, Draft Version 0.6 Problem: Suggested property string values Proposal: Per the last OFWG Meeting (6/25-26/96), the Network Recommended Practice added two properties to identify characteristics of the network adapter/device in the device tree: "supported-network-type" - all capabilities that the network adapter/device can support "chosen-network-type" - network adapter/device selected mode of operation This proposal is intended as a guideline for determining a value for these properties as new network technologies are implemented. The value is a string, as encoded with 'encode-string' that would cover known basic communication link characteristics like network type, data rate, connector type and duplexing mode information. The proposed string format would use a delimiter, "," (comma) between the values as shown below for parsing considerations: (BASIC NETWORK CHARACTERISTICS) Network Data Connector Duplexing Type Rate Type Mode (Mbps) -------------------------------------------------------------------- (Beginning list of defined characteristics) ethernet 4 rj45 half token-ring 10 bnc full fddi 16 aui fcs 25 15pin atm 100 utp 155 mic 622 sc 1000 9pin (NETWORK STRING VALUES) Proposed beginning set of network properties string values for the Network Recommended Practice Document: (ETHERNET) ethernet,10,rj45,half ethernet,10,rj45,full ethernet,100,rj45,half ethernet,100,rj45,full ethernet,10,aui,half ethernet,10,aui,full ethernet,100,aui,half ethernet,100,aui,full ethernet,10,bnc,half ethernet,10,bnc,full ethernet,100,bnc,half ethernet,100,bnc,full ethernet,10,15pin,half ethernet,10,15pin,full ethernet,100,15pin,half ethernet,100,15pin,full (TOKEN-RING) token-ring,4,rj45,half token-ring,4,rj45,full token-ring,16,rj45,half token-ring,16,rj45,full token-ring,4,9pin,half token-ring,4,9pin,full token-ring,16,9pin,half token-ring,16,9pin,full (FDDI) fddi,100,utp,half fddi,100,mic,half (ATM) atm,25,sc,full atm,100,sc,full atm,155,sc,full atm,622,sc,full (FCS) fcs,1000,sc,full [ P1275 Item #378 -- Received: Tue Jul 23 09:39:45 PDT 1996 ]
