摘要： In one embodiment, a data stream is scanned for presence of computer viruses using a stream-based protocol parser, a stream-based decoder/decompressor, and a stream-based pattern matching engine. The protocol parser may be configured to extract application layer content from the data stream to generate a file stream. The protocol parser may stream the file stream to the decoder/decompressor, which may decode/decompress the file stream to generate a plain stream. The decoder/decompressor may stream the plain stream to the pattern matching engine, which in turn may scan the plain stream for viruses. Advantageously, the aforementioned components may perform its function as soon as streaming data becomes available, without having to wait for the entirety of the data.

摘要： In one embodiment, an update file for an antivirus program is disassembled into several source packets. The source packets may be encoded using a forward error correction (FEC) algorithm to generate encoded packets. The encoded packets may include the source packets and redundant packets, the redundant packets including information that allows a client computer that includes the antivirus program to recreate the source packets even if it never receives all of the encoded packets. The FEC algorithm may be selected from several FEC algorithms based on the number of the source packets. The transmission of the encoded packets from a server computer to the client computer may be stopped when the client computer has received enough of the encoded packets to recreate the source packets.

摘要： A caller ID verifier may be employed to protect telephone users against caller ID spoofing. The caller ID verifier may be implemented in a telephony apparatus, such as a smart phone, stand alone caller ID device, or telephone network infrastructure, for example. Telephone numbers of related callers may be grouped into caller groups. The caller ID verifier may be configured to play one of several audio messages depending on the caller group of the telephone number corresponding to the caller ID of the telephone call. An audio message may include a question. The caller ID verifier may forward the telephone call to the telephone user when the caller answers the question correctly. Otherwise, the caller ID verifier may terminate the telephone call and give the telephone user the option to return the telephone call using the caller ID.

摘要： A method, apparatus, and computer program product for responding to congestion levels in a communication system by rate adaptation. A congestion condition is indicated by marking data packets. In response to receiving an indication of congestion, a data rate is reduced. A rate reduction inhibit timer is started, and further rate reduction is initiated if congestion is indicated after the rate reduction inhibit timer has expired. A rate increase timer is used to initiate a rate increase if no indication of congestion is received during a rate increase time.

摘要： A method, apparatus, and computer program product for indicating and responding to various congestion levels in a communication system, such as a wireless communication network. A congestion level in the network is determined, and a percentage of data packets to be transmitted to an endpoint, such as user equipment or another network endpoint serving the user, are marked to indicate the congestion level. The endpoint determines the congestion level at the network from the percentage of received data packets that are marked and may initiate an appropriate response behavior in response to the determined congestion level.

摘要： Disclosed are techniques for performing an antivirus task in a mobile wireless device running an embedded operating system. In one embodiment, calls intended for an application programming interface (API) function code is redirected to an antivirus function code. The redirection to the antivirus function code may be performed by modifying a kernel structure to point to a modified entry list instead of an API entry list. The redirection to the antivirus function code may also be performed by modifying the API function code to allow the antivirus function code to execute before the API function code. The kernel structure or the API function code may be properly restored back to its original form. Software implementations of these techniques may be readily loaded and unloaded, and may not require re-installation of the embedded operating system.

摘要： A method is disclosed that includes sending (304) a first full header from a source compressor (106) to a destination decompressor (112) wherein the source compressor and the destination decompressor are a part of a symmetrical configuration. An IP packet including the full header is compressed into a first compressed header (310) based on the context established in the first full header. The first compressed header is sent (312) from the source compressor to the destination decompressor. The compressor receives (322) a second full header from the destination compressor wherein the second full header indicates that the destination decompressor did not receive the first full header. The second full header can include a modified field or has an incremented generation identification. The source compressor sends (336) another full header to the destination decompressor.
