A Feistel network means that in each round, half of the text block is sent through an F function, and then XORed with the other half of the text block. Twofish is a Feistel network. DES is a Feistel network. Blowfish (another Schneier algorithm) is a Feistel network. Five of the AES submissions are Feistel networks.
