A remote network monitor for monitoring transaction-based protocols such as HTTP receives and analyzes protocol requests and associated responses, and derives therefrom a parameter associated with round-trip network latency. For example, TCP/IP acknowledgement packets can be used to deduce network latency. Such network latency and total latency parameters can be used to determine which portion of total latency can be attributable to the network and which portion is attributable to node processing time (e.g., server and/or client processing). A plurality of remotely located network monitors (and/or monitors co-located with servers and/or clients) can be used to derive and report on actual latency experienced throughout the network.

Methods of determining communications protocol latency

A method for communicating Internet Protocol data over a network, comprises providing an IPv4 data stream and providing an IPv6 data stream. An encrypted Internet Protocol communications tunnel is established through the network between a roaming mobile device and a further computing device. The IPv4 and IPv6 data streams are combined for encapsulation within and transmission through said encrypted tunnel. Continual secure communications of the encapsulated IPv4 and IPv6 data streams is maintained between said roaming mobile device and the further computing device while the roaming mobile device roams between network access points. The encapsulated, transmitted IPv4 and IPv6 data streams are received from said tunnel, and the received IPv4 and IPv6 data streams are demultiplexed.
