Claim Text:
1. A method for managing transmission characteristics for data communications between a first network site and a remote second network site of a wide area data communications network, wherein the data communications occur over a series of links of the data communications network, the method comprising: obtaining configuration information regarding a first node device of the first network site, wherein the configuration information reflects one or more transmission characteristics of the first node device with respect to outbound data communications transmitted to the second network site via a first link of the series of links of the data communications network, wherein the first link is between the first node device and a second node device serving as an entry point to a public portion of the data communications network; determining one or more outbound link throughput limits for the outbound data communications, wherein at least one of the outbound link throughput limit(s) is/are determined based on at least one of the transmission characteristic(s) of the first node device; and applying the outbound link throughput limit(s) to transmission of data packets of the outbound data communications; and wherein the configuration information is obtained by: sending a Simple Network Management Protocol (SNMP) request to the first node device for a device descriptor variable of the first node device and receiving a respective device descriptor value in response to the SNMP request; matching the received device descriptor value to a corresponding device identifier within a device management database, and retrieving one or more corresponding device SNMP variable types from the device management database; and polling the first node device for a respective device value corresponding to each of the one or more device SNMP variable types, wherein the device values reflect the configuration information.
