Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 15/16
G06F 3/00
G06F 9/44
G06F 9/46
G06F 13/00

US Classification:

709217, 719319

Abstract:

In a computational device, a technique provides network communications to a virtual machine. In particular, the technique includes receiving a first communications signal having a first address and data from an external device, performing a network address translation operation based on the first communications signal to obtain a second address that identifies the virtual machine and providing a second communications signal having the second address and the data, to the virtual machine. The technique may further include using an external network Internet Protocol address and port identifier and to translate the first communications signal into an internal network Internet Protocol address by accessing an entry of a network address translation table.

US Classification:

Abstract:

Mechanisms and techniques provide a system that operates in a computerized device(s) to establish a data distribution path for content within a content distribution network by receiving a network topology definition defining at least one hierarchical interconnection of network groups. Each network group comprises at least one content engine. The system also receives a channel definition comprising a selection of a plurality of content engines that are to distribute content within the content distribution network. The plurality of content engines in the channel definition is selected from content engines within the network groups defined within the network topology definition. The system determines an assignment of at least one root content engine within the channel definition and applies a content distribution path determination technique to the network topology definition in relation to the channel definition to determine a set of content distribution paths in the content distribution network to be used for distribution of content from the root content engine(s) to the content engines defined in the channel definition.

International Classification:

G06F 15/16

US Classification:

709218, 709203, 709229

Abstract:

This invention relates to methods for controlling and monitoring access to network servers. In particular, the process described in the invention includes client-server sessions over the Internet. In this environment, when the user attempts to access an access-controlled file, the server subjects the request to a secondary server which determines whether the client has an authorization or valid account. Upon such verification, the user is provided with a session identification which allows the user to access to the requested file as well as any other files within the present protection domain.

International Classification:

G06F 15/16

US Classification:

709229, 709227, 709250

Abstract:

A content delivery network has a content switch that intercepts content requests transmitted toward the origin server. The content switch distinguishes the content request as originating either external to the content delivery network or from within the content delivery network. The content switch forwards external requests to a content router, within the content delivery network and forwards internal requests to the origin server. Devices external to the content delivery network do not access the content carried by the origin server directly and, therefore, the content delivery network does not require the origin server alter its content when storing the content on a content server within the content delivery network. Use of the content switch, therefore, minimizes or eliminates the time, effort, and expense of rewriting content cached from the origin server to the content server within the content delivery network.

US Classification:

709220, 709226, 370 13, 370390

Abstract:

Conventional replication status reporting techniques in a Content Delivery Network (CDN) tend to produce large, unwieldy reports which are difficult to transmit, consume large amounts of bandwidth, and require a large share of CPU resources to process. A replication status reporter which identifies an ordered list of events corresponding to content items (files) for replication (pre-positioning) in a content delivery network, and determines a point of progression along a sequence represented by the ordered list of files, allows a management server to avoid computationally expensive endeavors which itemize and transmit lists of every replicated file in the CDN. The servers in a CDN channel receive files as a series of ordered events. Origin servers deliver the files generally according the event. A replication status report indicates the progression in the list, rather than enumerating the entire list, avoids cumbersome and unnecessary processing and delays in reporting replication status.

US Classification:

709219, 709227, 709230, 370389

Abstract:

An apparatus and method for defining content distribution paths in a content distribution network integrate unicast and multicast connections. Content engines in the content distributed network are organized into channels with a master content engine maintaining specific content. The content distribution network is further organized into a distribution hierarchy based on network topology and channel definitions, first by establishing unicast paths through the content distributed network and then by integrating multicast paths into the unicast hierarchy. The further organization of the content distribution network establishes distribution trees from the channel masters to the network edges.

US Classification:

707 5, 707 1, 707101, 709217

Abstract:

A method, system and apparatus are provided for dynamically pre-positioning content from servers located in a network, which may be a content distribution network. The content is pre-positioned on a proxy server, and the pre-positioning is triggered by at least one of the scheduling of an event and the presence of a user. Users commuting between different locations of a company can quickly and easily access the pre-positioned content. This content may be prioritized and pre-positioned, based on a user requiring a specific content at a particular time.

Abstract:

A security installation positions a peering ability with a peer installation by establishing a peering agreement to define the conditions constituting a situation for which peering applies, and identifies the resources and assets which will be shared, as well as the duration of the peering, typically until the resolution of the exigent situation or circumstances that prompted the peering. Peering selectively couples security installations for monitoring a particular upon determining that a situation responsive to mediation has occurred within an area monitored by the security installation for monitoring an area. The security installation initiates a peering invitation to a peer installation, in which the peer installation is configured to share resources with the security installation for mitigating the cause of the situation. The resulting peered access provides communication between the peer installation and the security installation, the access being temporary and conditional on the exigency of the determined situation.
