VxWorks currently supports loosely coupled network connections over serial lines (using SLIP, CSLIP, or PPP) or Ethernet networks (IEEE 802.3). It also supports tightly coupled connections over a backplane bus using shared memory. The standard VxWorks network stack uses the Internet protocols, based on the 4.4 BSD TCP/IP release, for all network communications.
In addition to the remote access provided by Tornado, VxWorks supports remote command execution, remote login, and remote source-level debugging. VxWorks also supports standard BSD socket calls, remote procedure calls, SNMP, remote file access, boot parameter access from a host, and proxy ARP networks.
Supported protocols: BSD 4.4 TCP/IP IP, UDP, TCP, IGMP, ICMP, ARP RIP 1/2 SLIP, CSLIP, PPP BOOTP, DNS, DHCP, TFTP FTP, RLOGIN, RSH, TELNET
In addition to the standard BSD socket interface, VxWorks also supports zbuf sockets, an alternative set of socket calls based on a data abstraction called the zbuf (the zero-copy buffer). Although this interface is WRS-specific, the interface can communicate with standard BSD sockets. Thus, the other end of the socket connection can use the standard BSD interface even if you chose to use the zbuf interface on the VxWorks side of the connection.
