Monitoring conditions within a switching network interconnecting two host systems engaged in a media call and adjusting the media parameters used by the host systems to improve call conditions.

Apparatus and method for media parameters selection based on network and host conditions

The present efficient packet encryption method decreases the computation time to encrypt and decrypt successive packets of plaintext data. An S-vector is generated and the S-vector is used to encrypt successive packets of plaintext, thus reducing the per packet encryption/decryption time. The formula for encrypting successive packets includes use of the packet sequence number with a third variable injected to eliminate the predictability of the variables, thus making the present efficient packet encryption method more secure. A fourth variable is injected into the calculations to generate an encryption stream that does not repeat as frequently to provide additional security from hackers. For encrypting a packet having a long payload of plaintext, a packet byte sequence number is used to generate an encryption stream that is less likely to repeat within a particular packet.
