The application relates to the technical field of communication, and provides a proxy routing method and
system. The method comprises the following steps: establishing a connection with an optical network
client based on a connection request sent by the optical network
client; the connection request carries routing information of a user
client; obtaining a target source IP according to the routing information; establishing a connection with a target
server based on the target source IP; and routing to-be-accelerated data to a target GRE tunnel according to the target source IP, so that the to-be-accelerated data enters an acceleration access point through the target GRE tunnel, and then is routed to a target acceleration link through the acceleration access point. In the proxy routing method provided by the application, the to-be-accelerated data is transmitted from a
proxy server cluster to an acceleration access point through a link most suitable for service requirements, and then is transmitted from the acceleration access point to a target acceleration link, and finally reaches a target
server; the link is most suitable for user service requirements, and thus the quality is good, and the problems of
packet loss and
delay in the transmission process of the to-be-accelerated data are effectively avoided.
