US 2014/0369189 A1 · METHOD OF CONTROLLING PACKET TRANSMISSION IN NETWORK SYSTEM AND NETWORK SYSTEM TRANSMITTING PACKET USING PSEUDO-TCP AGENT

Abstract

Provided are a method of controlling packet transmission in a network system and a network system that transmits a packet using a pseudo-transmission control protocol (TCP) agent. The method includes, when a packet is received from a transmitting device or a previous router, storing, at a router, the packet in a buffer and determining whether traffic exceeds a packet processing capacity, when it is determined that the traffic exceeds the packet processing capacity, controlling, at the router, an incoming packet rate to be reduced, when a congestion window is not filled with the packet to be transmitted to a next router or a receiving device due to the reduction in the incoming packet rate, waiting, at the router, until the congestion window is fully filled with a packet received thereafter, and transmitting, at the router, the packets filling the congestion window to the next router or the receiving device.

Dependent claims

A method of controlling packet transmission in a network system including a transmitting device, routers, and a receiving device, the method comprising:

when a packet is received from the transmitting device or a previous router, storing, at the router, the packet in a buffer and determining whether traffic exceeds a packet processing capacity;
when it is determined that the traffic exceeds the packet processing capacity, controlling, at the router, an incoming packet rate to be reduced;
when a congestion window is not filled with the packet to be transmitted to a next router or the receiving device due to the low transmission rate of the incoming packet, waiting, at the router, until the congestion window is fully filled with a packet received thereafter;
and
transmitting, at the router, the packets filling the congestion window to the next router or the receiving device.

2 more elements

A network system transmitting a packet using a pseudo-transmission control protocol (TCP) agent, the network system comprising:

a transmitting end terminal configured to transmit a packet;
a first router configured to store the packet received from the transmitting end terminal in a buffer, and control transmission of the stored packet using a first pseudo-TCP agent;
and
a second router configured to store the packet received from the first router in a buffer, and control transmission of the stored packet to a next node using a second pseudo-TCP agent.
