Hybrid security architecture (HSA) provides a platform for middlebox traversal in the network. The HSA decouples the middlebox control from network forwarding. More specifically, such embodiments may receive a data packet having a packet header including an Ethernet header identifying source and destination addresses in the network. A traffic type of the data packet is determined. Then, layer-2 forwarding information, which encodes a set of non-forwarding network service provider middleboxes in the network to be traversed by the data packet, is determined based on the traffic type. The layer-2 forwarding information is inserted into the Ethernet header and the data packet is forwarded into the network. The data packet will then traverse, according to the layer-2 forwarding information, a sequence of the middleboxes in the network, wherein at least one non-forwarding network service will be provided by each of the middleboxes to the data packet in a sequence.

The packet classification method for searching for a rule having a highest priority and matching among a plurality of rules included in a specified rulebase with respect to a packet input from an external network and processing the packet according to the searched rule. The method includes: a preprocessing step of partitioning the rulebase into a plurality of independent sub-rulebases based on a specified condition and producing a hash table on the basis of the sub-rulebases; and a classification step of classifying the packet by searching the hash table using a hash key extracted from a packet header of the inputted packet and mapping the packet on the sub-rulebase corresponding to the packet.

A service header is generated by an edge device (e.g., a gateway or a router) configured for providing a prescribed service operation for a prescribed network service for a received IP packet. The received IP packet includes an IP payload and an IP header having a protocol field specifying an original protocol of the IP payload. The edge device generates an encapsulated payload from the IP payload according to the prescribed network service, and generates a service header that identifies the prescribed network service and the original protocol of the IP payload. The edge device creates a modified IP header from the IP header and that identifies the service header in the corresponding protocol field, and outputs a modified IP packet including the modified IP header, the service header, and the encapsulated payload.

An electronic Yellow Pages viewer shows the pages of a Yellow Pages directory as they appear in the bound version. The print queue used to print the bound version is intercepted, and each page is rasterized into a JPEG file or otherwise converted into an image file. The page/header/advertisement data are parsed to create an index which associates each Yellow Pages heading with the first page on which that heading appears. The viewer runs as a Java applet inside a World Wide Web browser and allows a user to access a page by typing the name of a heading, selecting the heading from a tree view or typing a page number. A Yellow Pages advertiser receives an electronic bill with an electronic tear sheet showing the page on which the advertisement appears. The bill can also include one or more of the reverse page, the opposite page, or other pages in the same heading. The advertisement can be selectively highlighted.

Compression of message headers. A message including an uncompressed header, a message including a compressed header or a request to support header compression is received. In response, a determination of the impact of header compression on performance is determined. If the determination is favorable, then header compression is supported for subsequent communications. However, if the determination is not favorable, then header compression is not supported for subsequent communications. If the impact of header compression on performance is determined to be favorable, then an identifier for a reference header is returned. The identifier is for use in a subsequent compressed header. The subsequent compressed header comprises the identifier and changes relative to the reference header. A server receives a message including a compressed header. The server determines whether it has sufficient memory or storage to support header compression. If so, the server handles the message, but if not, the server refuses to handle the message or notifies a sender of the message that it will not support header compression for subsequent messages.

There is provided a mobile communications system in which at least a first and second type of message service are supported, wherein the system includes first and second application servers associated with the at least the first and second message service types, wherein the first and second types of message service are transported by an SIP message to the first application server, each SIP message including a control portion identifying the type of message, wherein the first application server is adapted to direct messages of the second type to the second application server.
