摘要： This invention provides methods and apparatus for web switching without connection termination while providing content routing functionality. Content-aware web switches terminate incoming TCP connections and inspect the HTTP header to recognize the URL (content) being requested from a web server farm. This invention maps application layer information (URLs) to MPLS labels. This allows a standard MPLS switch to provide web switching functionality without terminating TCP connections. In addition to content routing, this method is applied for client session affinity, server load balancing and service differentiation. This invention also relates to using TCP port numbers instead of MPLS labels to achieve web-switching functionality through the use of a TCP router that translates IP address and port numbers.
摘要翻译：本发明提供了用于在不提供内容路由功能的情况下连接终止的web切换的方法和装置。内容感知Web交换机终止传入的TCP连接，并检查HTTP头以识别从Web服务器场请求的URL（内容）。本发明将应用层信息（URL）映射到MPLS标签。这允许标准的MPLS交换机提供Web切换功能而不终止TCP连接。除了内容路由，该方法也适用于客户端会话亲和性，服务器负载均衡和服务差异化。本发明还涉及使用TCP端口号而不是MPLS标签来通过使用转换IP地址和端口号的TCP路由器来实现web切换功能。

摘要： A method for operating a server having a maximum capacity for servicing requests comprises the following steps: receiving a plurality of requests; classifying each request according to a value; determining a priority for handling the request according to the value, such that requests with higher values are assigned higher priorities; placing each request in one of multiple queues according to its priority value; and dropping the requests with the lowest priority when the plurality of requests are received at a rate that exceeds the maximum capacity. The server operates according to a session initiation protocol.Classifying each request comprises running a classification algorithm. The classification algorithm comprising steps of: receiving a rule set, each rule comprising headers and conditions; creating a condition table by taking a union of all conditions in the rules; creating a header table by extracting a common set of headers from the condition table; extracting the relevant headers from the header table; determining a matching rule; creating a bit vector table; selecting the matching rule according to data in the bit vector table; and applying the rule to place the message in the appropriate queue.

摘要： Provides methods and apparatus for offering tiered application services for access to network services on a pay-per-use basis in public access networks. Using personal devices, the user can access different tiers of application services on demand, without the need of any preexisting association, e.g., subscription, with the service provider of the wireless access system. Such on-demand access is obtained by providing a variety of personal identifiers, such as a credit card number or frequent flier identification. Moreover, the service offering allows a user through a personal device to modify, enhance or degrade the currently established tier of application services during the lifetime of the user's association with the access network. A network-level enforcement mechanism at access points within the access network ensures user access only to application services within the application service tier that they have paid for, and deny service accesses not within that tier.

摘要： This invention describes methods, apparatus and systems for virtualization of iSCSI storage. Virtual storage isolates the clients from the management of physical storage resources. In this invention, each physical storage device supports multiple logical units (LUNs). Each supported LUN is associated with a separate TCP port number and iSCSI commands received on a given port implicitly refer to the associated LUN. An iSCSI host addresses each logical unit of storage (LUN) with a virtual IP address and port number. Using an address translation table, the virtualization gateway rewrites the destination IP address in the header of an incoming packet as well as the destination port number to correspond to the target physical LUN. Migration of logical units across physical storage devices is supported by changing the address translation entries at the gateway; and the gateway can be provided by a standard network router with support for address translation.

摘要： This invention is directed to a system and method for the close coupling of Session Initiation Protocol (SIP) based Voice over Internet Protocol (VoIP) with multiplayer network games. Game state dependent voice communications are used as another method of player interaction in the game environment. The system uses SIP enhanced game servers and conference servers with audio mixing capabilities, and the game server controls the creation, maintenance and changing of the voice conferences. Participation in a voice conference is determined by the game state features associated with each player including distance and direction to determine how the voices are mixed in a voice conference.

摘要： In a method of transmitting an IP packet between a source and a destination through an ATM network which has a node formed by an ATM switch and a packet router, a reception packet or cell is transmitted to the node on an unused or undefined VC and is sent to the packet router in the node. In the packet router, an output port is selected by the use of the unused VC to establish a switched virtual channel in the ATM switch and to transfer each packet through the switched virtual channel after the switched virtual channel is established, as long as the reception packet is sent on the same VCI. Neither signaling nor protocol is needed between the nodes.
