Apparatus and accompanying methods for use therein for implementing an integrated, virtual office user environment, through an office server(s), through which a remotely stationed user can access typical office network-based applications, including e-mail, file sharing and hosted thin-client programs, through a remotely located network, e.g., WAN, connected web browser. Specifically, a front end, namely a service enablement platform (SEP), to one or more office servers on a LAN is connected to both the WAN and LAN and acts both as a bridge between the user and his(her) office applications and as a protocol translator to enable bi-directional, web-based, real-time communication to occur between the browser and each such application. During initial operation, the SEP, operating under a default profile, establishes, over an analog connection to the WAN, a management session with the site to obtain customer WAN access information, then tears down the analog connection and establishes a broadband WAN connection through which the SEP re-establishes its prior session and obtains a client certificate and its customized profile. The SEP then re-initializes itself to that particular profile.

Heuristic detection and termination of fast spreading network worm attacks
Methods, apparati, and computer program products for detecting and responding to fast-spreading network worm attacks include a network monitoring module (110), which observes (205) failed network connection attempts from multiple sources. A logging module (120) logs (220) the failed connection attempts. An analysis module (150) uses the logged data on the failed connection attempts to determine (225) whether a sources is infected with a worm using a set of threshold criteria. The threshold criteria indicate whether a source's failed connection attempts are non-normal. In one embodiment, a response module (160) responds (240) to the computer worm by, e.g., alerting a user or system administrator, terminating an infected process (20), or terminating the infected source's network access.

A user gains access to a private network by connecting to a network, either through a hardwired or wireless connection, and then initiates an Internet access request targeting any website. If the user is not already authorized for Internet access, then the user is sent to a first predetermined website that points the user to an authentication server accessible via the Internet. The authentication server sends the user an HTTP form pages requesting authentication information. When the user responds, a network monitoring device within the private network alters the form page to include the user's hardware address and an encoded ID based on the network's location. The authentication server forwards this data to a gate keeper server, which authenticates the new user and transmits an unblock message along with another encoded ID based on the network's location and the user's hardware address.

A network monitoring device includes a flow processing element, disposed to receive flow information relating to network flows, and to generate a set of virtual packets, each representing a portion of a network flow. The virtual packets are maintained in a time-sequential order, and read by elements of the network monitoring device to generate information relating to network traffic, such as symptoms affecting the communication network, problems affecting the communication network, and otherwise. The network monitoring device randomly samples virtual packets, with at least one of two effects: (1) flow information from traffic reporting devices that are themselves sampling at differing rates can be equalized, with the effect of standardizing information from all of them; (2) the network monitoring device itself can restrict its attention to a fraction of all virtual packets, with the effect of keeping up with a relatively large number of virtual packets.

A system for identifying chronic performance problems on data networks includes network monitoring devices that provide measurements of performance metrics such as latency, jitter, and throughput, and a processing system for analyzing measurement data to identify the onset of chronic performance problems. Network behavior is analyzed to develop a baseline performance level (e.g., computing a mean and variance of a baseline sample of performance metric measurements). An operating performance level is measured during operation of the network (e.g., computing a mean and variance of an operating sample of performance metric measurements). A chronic performance problem is identified if the operating performance level exceeds a performance threshold and a difference between the baseline performance level and the operating performance level is determined to be statistically significant. A t-test based on the baseline mean and variance and the operating mean and variance can be used to determine if this difference is significant.

Surveillance implementation in managed VOP networks
A procedure for accomplishing surveillance within a managed VoP network when end-user encryption / decryption and NAT are in place. The procedure comprises first analyzing the network from call signaling and message standpoints, leading to the identification of suitable surveillance access points (SAPs) for packet interception. A Delivery Function (DF) facilitated by the network service provider provides the means to intercept (without alteration) and replicate packets transmitted across the SAPs. The packets are then transmitted via the DF for collection within a Collection Function (CF), which is managed by a Law Enforcement Agency (LEA), for analysis by the LEA. This analysis provides, among other benefits, the opportunity to decrypt the intercepted packets and to identify additional suitable SAPs. In demonstrating the procedure, several embodiments of network surveillance models are described. Each one identifies the location of SAPs for that model. In each model, different information is collected and different processes are followed.

HyperLock queries collect time aggregated results for measure based operators with respect to a queried dimension. For each value of the queried dimension, the time interval buckets are traversed compiling a partial result that is finally stored in a stack as the time aggregated value. The stored sorted pointers are used to determine the starting location in each bucket with respect to the next value of the queried dimension.
