Implementation experience, + particularly on the effectiveness of the protocols in dual-stack + environments, is needed. + +1. Introduction + + Traditionally, TCP and UDP runs over IP. STD 17, RFC 1213 defines + TCP connection MIB object and UDP listener object assuming just that. + For TCP and UDP running over IPX, tcpConnTable and udpTable objects + from RFC 1213 cannot be used since they define the address to be of + type IpAddress. As such, we need to define new objects that can + properly describe TCP and UDP connections over IPX. + + New MIB objects, tcpIpxConnTable, udpIpxTable, tcpUnspecConnTable and + udpUnspecTable are presented in this paper, to be used in place of + tcpConnTable and udpListenerTable when TCP and UDP are running over + IPX. + +2.
