TOE- an Innovative Technology for Financial Institutions

In early 19 century, there was no protocol for processing the financial transactions, to process any financial transaction it takes a lot of time or even days. The traditional approach of TCP was very complex. The network interface card receives a data packet, the NIC interrupts the host CPU and the CPU extracts the data payload from the rest of the packet then moves data from the network buffer to the server’s memory so that an application can receive it. When data needs to be sent, the CPU is interrupted so that it can copy data from application memory to network buffer where it is divided into packets for eventual transmission across the network. Hence IP developers discover the TCP offload technology which is an extremely powerful technology that helps in transferring million of transaction in less than a second. This unique technology allows software to connect, communicate and decide in less than a second. This technology is especially designed for banks, data centers, cloud infrastructure, defense aerospace platform and network equipment.

TCP Offload, Full Kernel Bypass

Kernel Bypass is also known as OS bypass. This technique is uses mainly for optimizing network performance. The kernel decodes the network packet and passes the data from Kernel space to user space by copying to it. This technology involves network interface Card (NIC) Teaming, TCP Chimney offload, Data center TCP, Receive side scaling (RSS). Theoretically this technique helps in processing the data faster and fit more data into a given packet size. In kernel bypass the user space applications communicate with input/ output library and allows handling the communication directly.

UDP Offload

UDP stands for user datagram protocol or universal datagram protocol. However it is a connection less protocol but it is used in transferring messages. UDP offload is right for applications that need fast and efficient transmission and it is also effective for a server that answers small queries from huge amount clients. It is faster because there is no error checking of packets. It is light in weight as there is no ordering of messages and no tracking connections. It does not have recovery options but it follows error checking mechanisms. The only thing is UDP offload is that it does not process the data in order; all packets are independent on each other.

NIC with Full TCP Offload

The key advantages of TCP offload engine with NIC are:

– By offloading TCP/ IP engine and doing all the processing of TCP/IP through NIC with full TCP offload; it frees up the system for other useful work.

– When the offload processing is done on the network interface card (NIC), it removes some of the data transfers required since the card acts on the data locally.

It is not wrong to accept this fact that TCP technology has given a life to network servers. Network servers were suppose to face lot of stress as so many applications are running on servers and each application carries a much bigger and heavier file. The engineers who discover these innovative technologies are well experienced and have advance degree of PhD in engineering and computer sciences. So just like TCP there are other technologies that make the work simpler for us are on it way.
