Data transmission method and apparatus

This application provides a data transmission method and apparatus. The method includes: determining a first sending rate based on a network performance objective of first data and a network status of a first transmission control protocol (TCP) connection of a transport layer protocol, where the first TCP connection is used to send the first data; and sending the first data based on the first sending rate. In this way, network congestion control is more flexible, and TCP-based data transmission efficiency is improved.

Singular control path for mainframe storage

Providing TCP/IP control commands to a storage system includes intercepting TCP/IP data provided on a TCP/IP network, determining if the TCP/IP data corresponds to a control command directed to the storage system, and converting the TCP/IP data to a Fibre Channel control command that is forwarded to the storage system if the TCP/IP data is a control command directed to the storage system. A host may intercept the TCP/IP data. The host may be coupled to the storage system. The storage system may have only Fibre Channel connectivity. A PC having only TCP/IP connectivity may provide the control commands via the TCP/IP network. At least two hosts may be coupled to the TCP/IP network. Software on one of the hosts may provide the control commands for the storage system. The storage system may be coupled to an other one of the hosts.

APPARATUS AND METHODS FOR WIRELESS DATA COMMUNICATION USING SPECTRUM WHITE SPACES

There is described a computer implemented method for efficient aggregation of a Television White Space (TVWS) spectrum for backhaul use, said method comprising: providing a TVWS conversion substrate with a single antenna for combining multiple non-contiguous chunks of TVWS spectrum with said single antenna; providing a Multi-Path transport protocol; and providing an uncoupled, cross-layer congestion control algorithm for Multi-path Transmission Control Protocol (MPTCP).

MECHANISM TO ENABLE THIRD PARTY SERVICES AND APPLICATIONS DISCOVERY IN DISTRIBUTED EDGE COMPUTING ENVIRONMENT

A method and system support communication between a service executed by an edge server and a mobile application. The method includes receiving a transmission control protocol (TCP) handshake with an Internet Protocol (IP) anycast address from the mobile application; replying to the TCP handshake with an IP unicast address for the service to be utilized for a transport layer security (TLS) session; and establishing the TLS session between the service and the mobile application using the IP unicast address.

Using high speed data transfer protocol

Using high speed data transfer protocol to transfer data between a host and a storage system includes determining if a portion of data is a candidate for being transferred using the high speed data transfer protocol if the portion is not a candidate for high speed data transfer, transferring the data using a relatively low speed data transfer protocol if the portion is a candidate for high speed data transfer, attempting to transfer the data using the high speed data transfer protocol, and if transferring the data using the high speed data transfer protocol is unsuccessful, transferring the data using the relatively low speed data transfer protocol. The high speed data transfer protocol may use a first connection and the relatively low speed data transfer protocol may use a second connection. The first connection may be a PCIe or InfiniBand connection. The second connection may be a FICON connection.

Distributed resilient load-balancing for multipath transport protocols

Techniques are described for providing a distributed application load-balancing architecture that supports multipath transport protocol for client devices connecting to an application service. Rather than having client devices generate new network five-tuples for new subflows to the application servers, the techniques described herein include shifting the burden to the application servers to ensure that the new network five-tuples land in the same bucket in the consistent hashing table. The application servers may receive a hashing function utilized by the load balancers to generate the hash of the network five-tuple. By having the application servers generate the hashes, the load balancers are able to continue stateless, low-level processing of the packets to route them to the correct application servers. In this way, additional subflows can be opened for client devices according to a multipath transport protocol while ensuring that the subflows are routed to the correct application server.
