Summary
Network infrastructure is composed of various devices located either in the core or at
the edges of a wide-area network. These devices are required to deliver high
transaction throughput where a transaction may involve processing one protocol data
unit (PDU). Throughput of network infrastructure applications running on generalpurpose architecture based servers is constrained due to excessive memory access
latencies and limited memory transfer bandwidth. In this paper, we analyze the
memory access characteristics of three network infrastructure applications: IP
forwarding, HTTP proxying, and RTP streaming. In addition, we analyze the latencies
of these network applications with respect to three types of data transfers: memory-toCPU, memory-to-memory, and memory-to-network We calculate the optimistic
upper-bounds on throughput for these applications on general-purpose computing
platforms.
