In particular embodiments, a computing device receives a connection from an HTTP-compatible client. The device may assign the client a unique socket, launch a transcoding remote desktop client, receive a termination of the connection by the client, and update load-balancing information.

Techniques for provisioning and decommissioning web servers in an automated manner. In one embodiment, a threshold value relating to an operational metric of a web server can be stored. The metric can be monitored as the web server receives requests. If the metric exceeds the threshold value, additional web servers can be automatically provisioned to handle a portion of the requests. If the metric falls below the threshold value, the additional web servers can be automatically decommissioned. In another embodiment, information can be logged pertaining to web server requests received over time. Based on this information and a threshold value, patterns of high/low server load can be determined and a policy can be generated identifying time intervals during which additional web servers should be provisioned (or existing web servers should be decommissioned). The policy can be used at server runtime to provision or decommission web servers at the identified intervals.

The present invention includes a network service access method. In one embodiment, such a method comprises: forwarding the domain name resolution requests to a local domain name server of each Internet service provider providing services through access link corresponding with the Internet service provider; receiving Internet Protocol address on the domain name resolution requests which the local domain name server of each Internet service provider returned from the corresponding access link; selecting the Internet Protocol address according to line state of the access link of each Internet service provider providing services and returning the selected Internet Protocol address to the user equipments; and visiting network services by the access link of the Internet service provider returning the selected Internet Protocol address.

Generally described, the present disclosure is directed to managing request routing functionality corresponding to resource requests for one or more resources associated with a content provider. The processing of the DNS requests by the service provider can include the selective filtering of DNS queries associated with a DNS query-based attack. A service provider can assign DNS servers corresponding to a distributed set of network addresses, or portions of network addresses, such that DNS queries exceeding a threshold, such as in DNS query-based attacks, can be filtered in a manner that can mitigate performance impact on for the content provider or service provider.

A Dynamic Name Server (DNS) surrogation method, a DNS system, and a DNS server provide DNS surrogation which is the idea that if a user device sends a DNS resolution request to a given DNS server that server does not need to actually perform the recursion itself. A policy can be defined telling the server that first received the request to take other factors into account and “relay” or “surrogate” that request to another node. This additional node is called a “surrogate” and it actually performs the recursion therefore allowing the resolving party to perform proper localization, optimization, or any other form of differentiated resolution. This surrogation also distributes the job of actually performing resolution, which adds scalability to the DNS server or service itself. A network of “surrogate” resolvers is possible as well as the concept of every client needing DNS resolution can also become a surrogate.

A method, non-transitory computer readable medium and global traffic manager computing device for preventing distributed denial of service attack comprising machine executable code which when executed by at least one processor, causes the processor to perform steps including obtaining network information relating to a request in response to receiving the request. A rating is determined for the obtained network information based on one or more network parameters. An action to be taken for the received request is determined based on a comparison of the determined rating and a threshold rating. The determined action is executed for the received request.

Techniques for balancing network load at network devices in a virtualized computing environment are disclosed. In one embodiment, a first network device having network load above a threshold value is determined. Further, a first host coupled to the first network device is identified. The first host executes a workload that transmits and receives network traffic via the first network device. If the first host is not coupled to any other network device, the network load at the first network device is reduced by initiating migration of at least a part of the workload to a second host coupled to any other network device. If the first host is coupled to a second network device, the network load at the first network device is reduced by instructing a virtual switch of the first host to route at least a part of the network traffic between the workload and second network device.
