Abstract: A method for Multipath Quick User Datagram Protocol (UDP) Internet Connections (MPQUIC) over Quick SOCKS (QSOCKS) in a wireless network is provided. The method includes receiving, by a QSOCKS server, a Client Hello (CHLO) message from a QSOCKS client device using a QSOCKS method tag, wherein the CHLO message comprises a plurality of client-supported SOCKS Authentication (AUTH) procedures, selecting, by the QSOCKS server, a candidate client-supported SOCKS AUTH procedure from the plurality of client-supported SOCKS AUTH procedures, and transmitting, by the QSOCKS server, a reject packet using the QSKM tag to the QSOCKS client device, wherein the reject packet includes information indicating the selected candidate client-supported SOCKS AUTH procedure.

Abstract: Methods and systems for determining ICN capability of a node/server. The ICN capability is determined based on DNS resource records or TCP options. The DNS resource records are DNS queries that are sent to a DNS server, for determining the ICN capability of the server. The DNS query includes a content to indicate the intent to determine the ICN capability. If the server is having ICN capability, a DNS response is received from the DNS server, which includes the content that is identical to the content in the DNS query. A server is selected, amongst multiple servers, for transferring ICN packets, based on locations and priorities of the multiple servers, indicated in DNS responses, and an order of issuance of DNS queries to the DNS server. TCP options in the header of TCP packets are used for determining ICN capability of the nodes/servers and parameters pertaining to the ICN capability.

Abstract: The present disclosure relates to an apparatus and a method for controlling Transmission Control Protocol (TCP) connection close to improve a battery life time of a client such as a smart phone in a wireless communication system are provided. A method of operating a client in a wireless communication system includes determining a data transfer inactivity time of at least one of TCP connections, and closing the at least one of TCP connections at the data transfer inactivity time.
