  • Optimizing bandwidth of DSL connections
    Patent number: 7688848
    Abstract: An arrangement is provided for optimizing the bandwidth of DSL connections. A DSL connection is established via a customer premise equipment, a copper line connecting to the customer premise equipment, and a DSL access multiplexer connecting to the copper line. The DSL connection is operated at a transmission rate that is adaptively optimized through a DSL connection optimizer based on dynamic transmission environment.

  • Tagging packets with a lookup key to facilitate usage of a unified packet forwarding cache
    Patent number: 7269663
    Abstract: Apparatus and methods are provided for a Network Address Translation (NAT)-aware unified cache. According to one embodiment, multiple packet-processing applications distributed among one or more processors of a network device share one or more unified caches without requiring a cache synchronization protocol. When a packet is received at the network device, a first packet-processing application, such as NAT or another application that modifies part of the packet header upon which a cache lookup key is based, tags the packet with a cache lookup key based upon the original contents of the packet header. Then, other packet-processing applications attempting to access the cache entry from the unified cache subsequent to the tagging by the first packet-processing application use the tag (the cache lookup key generated by the first packet-processing application) rather than determining the cache lookup key based upon the current contents of the packet header.
