Abstract

Abstract A dynamic realtime, inband routing mechanism is disclosed for a data communications network, which provides an Event Driven Interface to perform realtime, inband directed routing for load distribution and load balancing of data frames over one of a plurality of destination paths. The Event Driven Interface is programmed with control vectors to identify load balancing and load distribution bit patterns in the data frames on the data communications network. Enabling signals produced by the Event Driven Interface are applied to the control input of a multiplexer whose data input is connected to the data communications network. The multiplexer will steer the data frames from the data communications network to one of a plurality of output alternative routing paths, in response to the enabling signals it receives from the Event Driven Interface.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 77 words
An apparatus for monitoring and controlling a data communications network which communicates a serial stream of binary bits having a characteristic pattern, for data frames which include load balancing and load distribution information, comprising: network Event Driven Interfaces having inputs coupled to said data communications network, programmed to identify characteristic data patterns in said load distribution and load balancing information of said data frames to accomplish load balancing and load distribution with a minimum number of bits.
Claim 2
Independent Claim 77 words
An apparatus for monitoring and controlling a data communications network which communicates a serial stream of binary bits having a characteristic pattern, for data frames which include load balancing and load distribution information, comprising: network Event Driven Interfaces having inputs coupled to said data communications network, programmed to identify characteristic data patterns in said load distribution and load balancing information of said data frames to accomplish load balancing and load distribution with a minimum number of bits.
Claim 3
Dependent Claim 122 words
The apparatus of claim 1 which further comprises: an Event Driven Interface having an input coupled to said data communications network, programmed to identify routing patterns in said load balancing and load distribution information of said data frames, for outputting an enabling signal in response to identifying said load balancing and load distribution bit patterns; a multiplexer having a plurality of control inputs coupled to said outputs of said Event Driven Interface and having a data input coupled to said data communications network for receiving said serial bit stream, and having a plurality of output paths, for outputting said serial bit stream over one of said plurality of output paths in response to said enabling signal received from said Event Driven Interface.
Claim 4
Dependent Claim 39 words
The apparatus of claim 1 or 2 which further comprises: a data frame buffer having an input coupled to said data communications network and an output coupled to said data input of said multiplexer, for buffering said data frame.
