Abstract: Described are sequence numbers for client-server communication, to control a client's use of server resources. A server grants the client credits, and the client consumes a credit for sending each command to the server. Each credit corresponds to a sequence number, with the set of sequence numbers forming a valid command window. The server enforces that for each received command, the command includes a sequence number that is within the valid command window and that the sequence number has not been used with another command. The server may also maintain a maximum window size, such that clients with credits cannot send a command with a sequence number that beyond a maximum sequence number. When incorporated into a data communication protocol, quality of service, combating denial of service, detection of message loss, division of server resources, secure message signing, and other numerous benefits result.

Abstract: A network includes a cache server and a network aware server that operates to determine an optimization between a cost of retrieving content from a communication network and a cost of caching content at the cache server. The optimization is determined as a minimum of a sum of a transit cost, a backbone cost, and a caching cost. The transit cost includes a money cost per data unit. The backbone cost includes a money cost per data unit and time unit. The caching cost includes a money cost per server unit. In response to determining the optimization, the network aware server sends a content identifier to the cache server, and the cache server receives the content identifier, determines a source of a content item, and if the source is the same as the content identifier, then cache the content item.

Abstract: Applications executed out of router memory may acquire additional bandwidth that is not being used by other applications, in order to speed up network traffic. Scavenging may occur up to a point where current congestion is detected, at which point any scavenged bandwidth is relinquished and the application returns to its prescribed limit. After current congestion is mitigated, scavenging may occur up to a limit below the point where congestion was detected. After a predetermined interval, additional scavenging may occur beyond this limit until a preset bandwidth limit is reached.

Abstract: A content delivery network is enhanced to provide for delivery of cacheable markup language content files such as HTML. To support HTML delivery, the content provider provides the CDNSP with an association of the content provider's domain name (e.g., www.customer.com) to an origin server domain name (e.g., html.customer.com) at which one or more default HTML files are published and hosted. The CDNSP provides its customer with a CDNSP-specific domain name. The content provider, or an entity on its behalf, then implements DNS entry aliasing (e.g., a CNAME of the host to the CDNSP-specific domain) so that domain name requests for the host cue the CDN DNS request routing mechanism. This mechanism then identifies a best content server to respond to a request directed to the customer's domain.

Abstract: A data center determines whether requested content is available at the data center. The content is available when the content is both present at the data center and current. When the requested content is available at the data center, the data center returns the requested content to the browser. When the requested content is locally unavailable at the data center, the requested content is retrieved from an origin server. When retrieval of the content is delayed, the request is prioritized and placed in a queue for handling by the origin server based on the priority of the request. A status page may be communicated to the browser to inform a user of the delay and provide alternate content and status information related to the request determined as a function of the request or the current state of the origin server.

Abstract: A personal computer's (PC) microprocessor is used to provide both the physical layer (PHY) and media access control (MAC) processing functions required to implement a wireless local area network (WLAN) adapter. This technique uses the polling mechanism associated with the power save (PS) functionality of WLAN protocol to relieve networking stress on the host processing system. It does this while maintaining networking integrity and packet delivery. The WLAN protocol polling mechanism is used to briefly inhibit the transfer of packets from the WLAN access point (AP) during peak periods of network traffic and/or host processor loading. Because the modulation, demodulation, and MAC functions, typically implemented in dedicated hardware on existing adapters are implemented in software running on the host PC microprocessor, other host system processes and applications can interfere with these time critical functions.

Abstract: Systems, apparatuses and methods for determining success rates for the transfer and/or utilization of transmitted applications or other communicated services. An intermediary device specifies one or more device attributes of a target device, which are received at a server. The server determines an anticipated success rate for successfully transferring the requested content to the device and/or utilizing the content at the target device, and transfers an indication of the anticipated success rate to the intermediary device. The anticipated success rate indication is received at the intermediary device, which then determines whether the received anticipated success rate indication meets threshold criteria. If so, the intermediary device notifies the server to initiate the transfer of the content from the server to the target device if the threshold criteria is met.

Meanwhile, the received protocol signals may be converted by the remote terminal for transmission through the satellite communications system in a format appropriate for that communication medium.

Abstract: Certain aspects of a method and system for transparent transmission control protocol (TCP) offload are disclosed. Aspects of a method may include collecting TCP segments in a network interface card (NIC) processor without transferring state information to a host system. The collected TCP segments may be buffered in a coalescer. The coalescer may verify that the network flow associated with the collected TCP segments has an entry in a flow lookup table (FLT).

When an event occurs that terminates the collection of TCP segments, the coalescer may generate a single aggregated TCP segment based on the collected TCP segments. The aggregated TCP segment and state information may be communicated to the host system for processing.

Abstract: A method for minimizing latency of data transfer between the redundant storage controllers in a network-based storage controller system that utilizes adaptive data throttling. Each redundant storage controller monitors latency for round trip communications between the redundant controllers by calculating a time required to mirror a write to the other controller and receive a write acknowledge. An average latency for round trip communications between the redundant controllers during a fixed monitoring period is calculated, and at the end of each fixed monitoring period, the average latency is compared to a fixed latency to access the average time latency for mirroring writes is good, acceptable or unacceptable. If the average time latency is good, the one controller reduces or disables throttling for data transfers between the one controller and the server, and between the one controller and back-end storage, increasing a number of this type of data transfer that can be executed in parallel.
