摘要:
A cross-host multi-hypervisor system, including a plurality of host sites, each site including at least one hypervisor, each of which includes at least one virtual server, at least one virtual disk that is read from and written to by the at least one virtual server, a tapping driver in communication with the at least one virtual server, which intercepts write requests made by any one of the at least one virtual server to any one of the at least one virtual disk, and a virtual data services appliance, in communication with the tapping driver, which receives the intercepted write requests from the tapping driver, and which provides data services based thereon, and a data services manager for coordinating the virtual data services appliances at the site, and a network for communicatively coupling the plurality of sites, wherein the data services managers coordinate data transfer across the plurality of sites via the network.
摘要:
A system for cloud-based data services for multiple enterprises, including a plurality of cloud hypervisors that cooperatively provide cloud-based services to multiple enterprises, each hypervisor including a plurality of cloud virtual servers, each cloud virtual server being associated with an enterprise, at least one cloud virtual disk that is read from and written to by the at least one virtual server, each cloud virtual disk being associated with an enterprise, and a virtual data services appliance, which provides cloud-based data services, and multiple data services managers, one data services manager per respective enterprise, each of which coordinates the respective virtual data services appliances for those cloud hypervisors that service its corresponding enterprise.
摘要:
A data center for data backup and replication, including a pool of multiple storage units for storing a journal of I/O write commands issued at respective times, wherein the journal spans a history window of a pre-specified time length, and a journal manager for dynamically allocating more storage units for storing the journal as the journal size increases, and for dynamically releasing storage units as the journal size decreases.
摘要:
A method is disclosed for determining attributes of a client connection configured for use with a telecommunications network; comparing determined attributes with location definition information stored in a configuration file; determining at least one user-defined location in the location definition information associated with the client connection based on the comparison; wherein the method is performed by one or more computing devices.
摘要:
A method is disclosed for determining a location of a client session in a telecommunications network by comparing attributes of the client session connection to location definition information stored in a configuration file. A method of handling requests from proxy and non-proxy client connections in a telecommunications network by redirecting requests from unauthenticated proxy clients to a transparent proxy port on a captive portal such that the captive portal proxies the requests is also disclosed. The request may be directed to a service, such as a destination IP address and optional port number. A method for a proxy server to identify an edge session through an out-of-band request containing proxy metadata to a web portal for secure (HTTPS) requests is also disclosed. The edge session is identified for the web portal through a hostkey determined by the proxy server.
摘要:
A method for connecting a user computer to a first computer network includes transmitting a connection request by the user computer, via a second computer network, requesting a connection to the first computer network. The second computer network is automatically solicited to authorize the user computer, responsively to a failure of the connection request. Upon authorization by the second computer network, a connection is established between the user computer and the first computer network via the second computer network.
摘要:
A method is disclosed for determining a whether access to host requested by a user is permitted. User identifying information is obtained using any of a variety of techniques. The method includes determining a user domain, which indicates an identity of the user's home service provider. A list of hosts is determined based on the home provider. If the requested host is in the list of hosts, then the user is allowed access to the requested host though the user is not authorized. The list of hosts may be determined by one or more attributes from an actual or implied user profile, such as a domain name.

摘要:
A method of limiting domain name server (DNS) transaction bandwidth comprises intercepting one or more DNS packets, examining said one or more packets for the presence of a suspect transaction criterion and, if said suspect transaction criterion is present, implementing a transaction bandwidth limitation action.
