Forwarding data unit associated with limit value

摘要

Among other disclosed subject matter, a computer-implemented method for forwarding data includes receiving a data unit that is on a route toward a destination. The data unit is associated with a first limit value regarding forwarding of the data unit. The method includes causing the data unit to be associated with a second limit value at least equal to the first limit value. The method includes forwarding the data unit to a next recipient in the route, the data unit associated with the second limit value.

1. A computer-implemented method for forwarding data, the method comprising:
receiving, at a first node of a network, a data unit that is on a route toward a destination, the data unit having a first time-to-live (TTL) value; determining, in response to receiving the data unit and by accessing a configuration record that includes information about nodes in the network other than the first node, a value to add to the first TTL value; based on determining the value to add to the first TTL value, assigning the data unit a second TTL value;
and forwarding, after assigning the second TTL value, the data unit to a next node in the route, the data unit associated with the second TTL value.
