A communication system speeds up digital traffic between nodes. The traffic is organized into data frames flowing over network high and low speed links attached to entry and exit ports of the nodes. Low speed modules connect the low speed links to a high speed switch. Router dispatch modules connect the high speed switch to a node attached to a high speed link for forwarding each data frame toward a dynamically selected target low speed module via the high speed switch, such that the dynamic selection of the target low speed module is based on detection of the module with the least load. At least one main router is attached to the high speed switch for storing a routing table to enable the targeted low speed module to orient one of the frames toward a right node exit port.

High-speed digital network node communication system and method

A method for improving next hop selection between internet routers (R) defined by their respective IP addresses. A source is identified by a source IP address and a source port identification. A destination or target is defined by a target port identification. Equivalent routes toward the destination host are identified conventionally. Each of the equivalent routes is defined by next router IP address. The source IP address, source port identification and target port identification are logically combined to derive a connection identifier (HO) for a first router common to all paths. An set of additional logical operations are performed to derive next hop selection identifiers. Final next hop route selection is based on predefined criterion.
