In most cases, NetX Duo can determine the best source address to use when transmitting a packet. The source address selection is based on the destination address. NetX Duo services are added to allow applications to specify a specific source address to use, in cases where the most suitable one cannot be determined by the destinationaddress. An example would be in a multihome system, an application needs to send a packet to an IPv4 broadcast or multicast destination addresses.

A raw IP packet is an IP frame that contains upper layer protocol payload not directly supported (and processed) by NetX Duo. A raw packet allows developers to define their own IP-based applications. An application may send raw IP packets directly using the nxd_ip_raw_packet_send service if raw IP packet processing has been enabled with the nx_ip_raw_packet_enabled service. When transmitting a unicast packet on an IPv6 network, NetX Duo automatically determines the best source IPv6 address to use to send the packets out on, based on the destination address. If the destination address is a multicast (or broadcast for IPv4) address, however, NetX Duo will default to the first (primary) interface. Therefore, to send such packets out on secondary interfaces, the application must use the nx_ip_raw_packet_source_send service to specify the source address to use for the outgoing packet.
The User Datagram Protocol (UDP) provides the simplest form of data transfer between network members (RFC 768). UDP data packets are sent from one network member to another in a best effort fashion; i.e., there is no built-in mechanism for acknowledgement by the packet recipient. In addition, sending a UDP packet does not require any connection to be established in advance. Because of this, UDP packet transmission is very efficient.
Sending UDP data over IPv6 or IPv4 networks is easily accomplished by calling the nxd_udp_socket_send function. The caller must set the IP version in the nx_ip_version field of the NXD_ADDRESS pointer parameter. NetX Duo will determine the best source address for transmitted UDP packets based on the destination IPv4/IPv6 address. This service places a UDP header in front of the packet data and sends it out onto the network using an internal IP send routine. There is no thread suspension on sending UDP packets because all UDP packet transmissions are processed immediately.
Active LatencyMonitoring provides a real-time view of the latency that is incurred by thepackets while traveling through the switch on a per port basis. The latencymeasurement is FIFO measurement. Functionally, as soon as the packet enters theswitch, the ASIC adds a timestamp to it. When it is scheduled to go out of theegress port, the egress port calculates the latency for each packet that isgoing out of that port based on current time and the ingress timestamp on thepacket.
Except as provided by 117.5(k)(1), subpart B of this part applies to the off-farm packaging, packing, and holding of raw agricultural commodities. Compliance with this requirement for raw agricultural commodities that are produce as defined in part 112 of this chapter may be achieved by complying with subpart B of this part or with the applicable requirements for packing and holding in part 112 of this chapter.
So far in this chapter we have assumed that the switches and routershave enough knowledge of the network topology so they can choose theright port onto which each packet should be output. In the case ofvirtual circuits, routing is an issue only for the connection requestpacket; all subsequent packets follow the same path as the request. Indatagram networks, including IP networks, routing is an issue for everypacket. In either case, a switch or router needs to be able to look at adestination address and then to determine which of the output ports isthe best choice to get a packet to that address. As we saw in an earliersection, the switch makes this decision by consulting a forwardingtable. The fundamental problem of routing is how switches and routersacquire the information in their forwarding tables.
A second version of the ARPANET routing algorithm took both linkbandwidth and latency into consideration and used delay, rather thanjust queue length, as a measure of load. This was done as follows.First, each incoming packet was timestamped with its time of arrival atthe router (ArrivalTime); its departure time from the router(DepartTime) was also recorded. Second, when the link-level ACK wasreceived from the other side, the node computed the delay for thatpacket as
Control transfers are typically used for command and status operations. They are essential to set up a USB device with all enumeration functions being performed using control transfers. They are typically bursty, random packets which are initiated by the host and use best effort delivery. The packet length of control transfers in low speed devices must be 8 bytes, high speed devices allow a packet size of 8, 16, 32 or 64 bytes and full speed devices must have a packet size of 64 bytes.
