It is described a network attack detection method. A topology analysis on network is conducted to obtain a probing path set containing at least one probing path. A first probing path contained in the probing path set is probed by using a probing pattern to obtain a performance metric of the first probing path. It is determined whether the first probing path is subjected to network attack according to the performance metric and a control performance metric.

Network attack detection method

It is described an information processing method and device. It is received a request for service data from a client device. In response to the request for service data, it is sent at least two probing packets which contain the service data to the client device on a forward path which is from a server to the client device. It is obtained timing information, which includes: a time stamp corresponding to the service data, a time stamp corresponding to the request for the service data, and time stamps corresponding to at least two backward-path packets sent by the client device on a backward path, the backward path being from the client device to the server. It is determined according to the timing information a one-way path metric.

Information processing method and device

Various embodiments provide methods, apparatus, and systems for allocating content delivery network (CDN) volume. In an exemplary method, a business visit request can be received. Based on at least one of a time allocation strategy, a request number allocation strategy, and a regional allocation strategy, the business visit request can be dispatched to CDN servers for handling the business visit request.

Method, apparatus, and system for allocating CDN volume

Embodiments of the present invention provide a method, system and DNS server for load balancing network servers. The method includes: monitoring whether each network server is capable of providing a network service, deleting an IP address of a network server which is incapable of providing a network service from an IP list in a DNS server or setting the IP address as invalid in the IP list according to a monitoring result; receiving, by the DNS server, a request from a network user for accessing a network server, selecting an IP address from valid IP addresses in the IP list which corresponds to the request; providing, by a network server having the selected IP address, network services for the network user.
