datagram

[′dad·ə ‚gram]
(computer science)
A unit of information in the Internet Protocol (IP) containing both data and address information. In TCP/IP networks, datagrams are referred to as packets.

datagram

A self-contained, independent entity of data carrying sufficient information to be routed from the source to the destination computer without reliance on earlier exchanges between this source and destination computer and the transporting network.

See also connectionless, frame, packet.

datagram

The unit of data, or packet, transmitted in a TCP/IP network. Each datagram contains source and destination addresses and data. See TCP/IP and UDP.

Datagram provides highly reliable, scalable, data center based services, such as dedicated hosting, Internet access, colocation and disaster recovery.
This option contains the home address of the mobile node sending a packet so that when a correspondent node receives a datagram that uses the care-of address as the IPv6 Source Address, MIPv6 obtains the home address.
As an example, a real time AV feed might have very specific requirements with regard to datagram latency, sequencing, and loss characteristics.
NEW YORK -- Datagram, the provider of Internet Solutions Made Simple, and CRG West, a premier colocation and datacenter management company, announce today that Datagram has expanded its state-of-the-art IP network by adding a Point of Presence (POP) in CRG West's One Wilshire data center in Los Angeles.

SIP, along with Quality of Service (QoS) based on PacketCable Multimedia (PCMM), provides a foundation for the delivery of advanced services, including fixed-mobile convergence (FMC) -- allowing consumers to "hand off" a cellular call to a Wi-Fi(R) network and landline phone, rich multimedia communications, such as interactive video sessions, secure signaling and encryption, and flexible Network Address Translation (NAT) and firewall traversal technologies like Simple Traversal of User Datagram Protocol (UDP) Through Network Address Translators (STUN).
These are: network throughput, datagram loss rate, datagram latency, and datagram sequencing.
