A Packet-Combining Algorithm Based on SSLVPN with Hardware Acceleration Devices

SSLVPN is widely used in Web applications, e-commerce, teleworking, etc...Due to the need to provide security, the complex computing has been seriously upset the performance of SSLVPN, may even cause the VPN throughput rates decline by one to two orders of magnitude. To improve SSLVPN encryption performance, domestic and foreign scholars have made a number of studies. This paper focuses on the SSLVPN with hardware acceleration devices, and put forward a packet-combining algorithms，which could effectively improve encryption performance and data throughput of SSLVPN.
