15 December 2017 - A group controlled by Solomon Yan and Ellis Yan, former CEO of TCP
, has agreed to acquire all shares of Ohio, US-based lighting manufacturer TCP
International Holdings, Ltd.
uses three way handshaking for connection establishment and four way handshaking for connection termination.
Once a TCP
has been approved, company personnel, including non-U.
data transfers typically start slowly and then ramp-up to their maximum transfer rate over time.
Most standard TCP
implementations are limited to 65-Kbyte windows.
Our new approach to TCP
acceleration fits with our overall Cooperative Tele-Optimization strategy whereby distant sites can achieve maximum efficiency without installing extra hardware or software at every site," said Vargha Moayed, executive vice president of Ipanema Technologies.
Acknowledgement Scheme: TCP
causes the entire stream from any lost portion to be retransmitted in its entirety.
The processing needed to perform for a full-offload TOE includes a check of the Ethernet CRC, check of hardware addresses, frame type check, checking and processing of any VLAN tags, stripping of the Ethernet frame header, a lookup on destination IP address in an address cache, a check for the correct protocol, calculation and check of the IP checksum, stripping of the IP header, parsing of TCP
flags, a lookup on source and destination IP addresses and ports, creation of TCP
pseudo-header checksum, calculation of the TCP
checksum, stripping the TCP
header, and DMA of the packet data to host memory.
The company pioneered Local Instance Networking, a technology that reduces "server sprawl" and achieves exceptional acceleration for all applications, including bulk TCP
applications, file transfer services, real-time applications like Citrix, media applications and VoIP in an application transparent manner.
TOEs are being used because TCP
requires a great deal of processor overhead to transport data (from Adaptec, Agilent, Emulex, Qlogic, and Troika).
Port 445 is often exposed to the Internet because the Microsoft-DS Service uses port 445 for resource sharing on Windows 2000, XP, 2003, and other samba based connections.
The problem is that both the robustness and the congestion of the Internet arise because it's a dumb network--the intelligence is at the endpoints, much of it encapsulated in TCP
, which is responsible for seeing that all the packets in a connection eventually reach the endpoint in the proper order, and, even more important, is also responsible for controlling congestion via flow control.
