Two words that can be quite trendy by themselves, but stuck together as if forgotten at a bus station long past the last ride of the night, the phrase rings a number of different, and at times discordant, bells. | 382 Index SDP Session Description Protocol format 21 codec negotiations and 53-55 description 53 53t responding description 54-55 55t as a text-based protocol 53 sectorization 120 secure password-based authentication 336 secure RTP 52 55 341-342 secure SIP 32 Secure Socket Layer TLS replacing 334 secure wireless network 169-170 security for 169-192 in controller-based architecture 121 principles of 324 technologies in Wi-Fi 170-180 for voice mobility networks 323 security handoff overhead reducing 252-253 segment in Ethernet 78 self noise 135-136 send loudness 61-62 sender s noise 61-62 sequence control field 111 111t Sequence field in TCP 88 sequence number in IPsec 338-339 in the sequence control field 114 serial number of a certificate 333 serial protocol Ethernet as 77-78 server failure codes in SIP 30 Server Hello Done message 187-188 188t Server Hello message 187-188 188t Service Control Point SCP 42 service disruption during transitions 276-277 service period in WMM Power Save 213 service provider for Wi-Fi 233 service set identifier.
