Abstract: Embodiments of a method and apparatus to improve network performance by managing packet fragmentation with address translation are described.

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.

Abstract: Techniques to manage address translation for secure connections are described. An apparatus may include a secure connection manager. The secure connection manager may comprise a flow module to create a list of identifiers, with each identifier representing a secure flow terminating at a device with an internal address. The secure connection manager may also comprise a translation module to select an internal address for an encrypted packet having an external address and a flow identifier. Other embodiments are described and claimed.
